The advent of wireless routers has helped small offices and home computers interconnect and function fast. No more sharing of files with thumb drives or squabbles over who will access the internet fast. If you have notebook or laptop you can keep repositioning your place of work within your house, such is the convenience of wireless networking. With a little bit of planning you can configure a network that suits your business requirements the most.
The task of settling for a particular model of wireless router can be very puzzling. There are many models from various manufacturers and each with many features. Some of the features of wireless routers to check out before buying one are explained below.
Firewalls are ideal for home networks. They help in protecting home use computers by stalling the destructive efforts of other official websites and potential hackers. This software or hardware device filters the information coming through the internet connection, flagging the information that is not to be allowed through. You can find some such models at: http://www.reviewgist.com/wireless-router-reviews?routerFunctionalities=Firewall
VPN pass through feature of routers allows traffic between the endpoints and does not support one of the endpoints. This feature is ideal for routers of home use or small office setups; they are less expensive than a router with full VPN that supports the endpoints. Check these models at: http://www.reviewgist.com/wireless-router-reviews?routerFunctionalities=VPN+Pass-Thru
Dynamic Host Configuration Protocol (DHCP) servers can be implemented for windows based system. The server automatically assigns an IP address to the computer’s TCP/IP stack software. Check out the models having this feature at: http://www.reviewgist.com/wireless-router-reviews?routerFunctionalities=DHCP+Server
The performance of your network will depend on signal strength of the wireless access point. Before you position it, find out the exact location from where it will give the maximum network range. Check out some of the devices at: http://www.reviewgist.com/wireless-router-reviews?routerFunctionalities=Wireless+Access+Point
Digital Subscriber Line modems are faster than regular modems and can use the existing phone lines. Both internet connection and phone lines for telephone calls can be used simultaneously. Some such models are: http://www.reviewgist.com/wireless-router-reviews?routerFunctionalities=DSL+Modem
VoIP routers have both wireless networking feature and telephone terminal adapters. With this feature the network can access both Internet and voice communications. Some models are: http://www.reviewgist.com/wireless-router-reviews?routerFunctionalities=Voice+over+IP+Gateway+%28VoIP%29
Protocols
These are formats for transferring data between the various devices. The protocols determine the various aspects of the data like compression types, delivery and retrieval by devices and error checking. The standard protocols differ in their various features, so in order to communicate with other computers correct protocols must be selected.
Internet Protocol (IP) enables unique addressing for computers.
When used with transport control protocol, it is referred as TCP/IP.
The newer IP version 6 is referred as IPv6. This version addresses 16 bytes in length.
DHCP: Dynamic Host Configuration Protocol assigns dynamic IP addresses to devices on a network.
The information packets have to be routed by a series of routers to get to its destination. Latest routers automatically exchange route information with other routers through the use of routing protocols.
While configuring the router on your own, you have to choose what types of routing protocol you have to install and configure. Check models with different routing protocols at:
Static routing: http://www.reviewgist.com/wireless-router-reviews?routingProtocols=Static+Routing
RIP version-1: It is a dynamic protocol and automatically figures routing tables on its own, thus manual inputs are not required. http://www.reviewgist.com/wireless-router-reviews?routingProtocols=RIP+Version+1
This feature configures the virtual private network, encryption hardware advanced integration modules and the network modules.
Data Encryption Standard – applies 56-bit key to 64-bit block of data. This is the most commonly used encryption standard. A single key is used which is very difficult to break. Some models with this feature are available at: http://www.reviewgist.com/wireless-router-reviews?encryptionStandards=DES
Triple DES (3DES) – applies 3 keys in succession making it more difficult to break the code. Check at: http://www.reviewgist.com/wireless-router-reviews?encryptionStandards=3DES
Advanced Encryption Standard (AES) will be the next encryption standard for commercial transactions in the private sector. Check such models at: http://www.reviewgist.com/wireless-router-reviews?encryptionStandards=AES
MD5 – Check these models at: http://www.reviewgist.com/wireless-router-reviews?encryptionStandards=MD5
SHA 1 – Such models are available at: http://www.reviewgist.com/wireless-router-reviews?encryptionStandards=SHA-1
There are many standards of modulation. The most commonly used types are:
QAM: Quadrature Amplitude Modulation, a dominant modulation technique for high speed digital signals.
CCK: Complimentary Code Keying is a modulation scheme to operate in data speeds up to 11Mbps in the RF band.
OFDM: Orthogonal Frequency division multiplexing modulation is used for even higher speeds of 54Mbps.
DSSS: Direct Sequence Spread Spectrum use wideband signals that are not easy to detect and resists jamming attempts.
Today no home and office network is secure. To counter the hacking efforts of hackers, look for good built-in security functionalities. These will ensure that your system doesn’t slow down, those within the range of your wireless are not able to view your files, emails, instant messages, usernames and passwords. Depending on the security features you can also block spams, illegal activities with your internet connection and prevent loading of dangerous software.
This however doesn’t mean your network is completely secure.
Some steps that can be taken are:
Enable WEP, wired equivalent privacy encryption provides security to WLANS. The WEP keys encrypt the data stream. Check these models: http://www.reviewgist.com/wireless-router-reviews?security=WPA
Turning on WPA encryption. The Wi-Fi protected access adds on the authentication and encryption features WEP explained above. Check at: http://www.reviewgist.com/wireless-router-reviews?security=WEP
TKIP, Temporal Key Integrity Protocol covers up for the encryption weaknesses of WEP. Some such models are: http://www.reviewgist.com/wireless-router-reviews?security=TKIP
WPA2 protection is the latest one and provides high level of protection. Find such models at: http://www.reviewgist.com/wireless-router-reviews?security=WPA2
Enable wireless MAC Address filtering. Check at: http://www.reviewgist.com/wireless-router-reviews?security=Wireless+MAC+Address+Filtering
WEP Encryption length
The WEP encryption is based on a combination of secret user keys and system generated values. The key encrypts and de-encrypts the data that is transferred between the access points and the clients. There are two versions:
The earlier version supported 40-bit encryption; the key length was 40 bits and 24 additional bits of system generated data, thus a total of 64 bits. Check out the respective models at: http://www.reviewgist.com/wireless-router-reviews?wEPEncryptionLength=40-to-128
Easy decoding of 40 bit WEP encryption encouraged vendors to go in for 128-bit encryption. 128-bit encryption has a key length of 104 bits. You can find such models at: http://www.reviewgist.com/wireless-router-reviews?wEPEncryptionLength=128-to-256
The omni directional antenna of routers broadcast 360degrees around the router. Position them in such a way that you can make the most of the radiating signals.
External antennas can add strength significantly, thus giving a wider range and increased network performance when compared with the performance of in-built antennas. Check models with external antenna at: http://www.reviewgist.com/wireless-router-reviews?antennaType=External+Antenna+x+1
Detachable antennas disable 802.11a lower band communications when detached. On attaching the antenna the lower band is enabled. Thus they can be screwed into the device and can be upgraded easily. Check out different types at: http://www.reviewgist.com/wireless-router-reviews?antennaType=Detachable+Antenna+x+1

GPS units give the electronic routes and voice guided turn by turn directions to your destination. As technology has progressed in this field, you get plenty of models in the market with various accessories and add on features, some extremely useful. The basic features you need to look out for before you buy one are explained in the following sections.
Map Capabilities
Most GPS models come with internal map capabilities. Manufacturer provides maps with details up to street level in the hard drive. The menu option enables you to access the desired data. Comprehensive street level maps can help you identify the coordinates of the destination on the map by just using the name, or locate the destination on map by giving the coordinates. For some models you will have to subscribe to a plan to update the maps on an annual basis. Check out some models with internal map capabilities at: http://www.reviewgist.com/gps-devices-reviews?mapCapabilities=Internal
Some models provide map information in memory cards having detailed information of a particular region. Thus you will need extra cards if you have to store information for more coverage. Map cartridges are more flexible but can prove to be expensive. Check the few models at: http://www.reviewgist.com/gps-devices-reviews?mapCapabilities=Map+cartridges+%2F+Data+cards
Models which enable one to download the latest maps are also available. Check such models at:
http://www.reviewgist.com/gps-devices-reviews?mapCapabilities=Download+maps
Some brands provide map information in CD-ROM, DVD-ROM discs. Check out one such model at: http://www.reviewgist.com/gps-devices-reviews?mapCapabilities=DVD
Receiver type
There are 24 GPS satellites in six orbits around the earth. GPS receivers track these satellites to compute the information of your location, the bearing, distance and time left to reach destination and other route options. Since there are 12 satellites at a time in view, each of them is tracked continuously to generate the information. Latest GPS receivers marketed today are commonly 12 parallel channel receivers. You can find some such models at: http://www.reviewgist.com/gps-devices-reviews?receiverType=Parallel-Channel+%2812%29
The associated advantages of tracking more satellites are:
faster cold start
regular initialization
better reception
do not require an external antenna if you are in an open vehicle
Other receiver types are:
20 parallel channel receivers http://www.reviewgist.com/gps-devices-reviews?receiverType=Parallel-Channel+%2820%29
16 parallel channel receivers http://www.reviewgist.com/gps-devices-reviews?receiverType=Parallel-Channel+%2816%29
14 parallel channel receivers http://www.reviewgist.com/gps-devices-reviews?receiverType=Parallel-Channel+%2814%29
Display size
Large displays are a visual treat when you consider buying TVs but not the same when it comes to buying a GPS. The map on the display gives you information regarding:
current location
where next turn is
name of street you are turning onto
estimated time of arrival
While driving, casting your glance away a second longer can prove to be risky, hence a device with a smaller screen will be advantageous. The display should be easy to read irrespective of surroundings. The navigation aids come in various sizes. Some units with screen size as big as 7in. (http://www.reviewgist.com/gps-devices-reviews?displaySize=7+in.) enable you to get connected to external video devices. Some hand held ones are as small as 1.5in.X 0.9in. (http://www.reviewgist.com/gps-devices-reviews?displaySize=1.5+in.+x+0.9+in.). Some of the convenient easy to read GPS are:
3.5 in. (http://www.reviewgist.com/gps-devices-reviews?displaySize=3.5+in.)
2.8 in. x 2.1 in. (http://www.reviewgist.com/gps-devices-reviews?displaySize=2.8+in.+x+2.1+in.)
Resolution
Screen resolution decides how clearly you can see and read in broad daylight. Color, glare free LCDs are soothing to the eyes. High end models have color screens which gives information about weather and terrain. Some GPS units with different resolutions are:
320×240 http://www.reviewgist.com/gps-devices-reviews?resolutions=320+X+240
480×272 http://www.reviewgist.com/gps-devices-reviews?resolutions=480+x+272
PC Interface
The portable models have a USB or serial ports which gets you connected to a PC. It enables you to download latest maps and system software. GPS units with USB and serial ports can be found at:
USB: http://www.reviewgist.com/gps-devices-reviews?pcInterface=USB
Serial port: http://www.reviewgist.com/gps-devices-reviews?pcInterface=Serial+RS-232
Bluetooth GPS that communicates with mobile device wirelessly are also available. Some can be found at: http://www.reviewgist.com/gps-devices-reviews?pcInterface=Bluetooth+Wireless+Technology
Built-in memory
With larger memory space one can store more route information and waypoints. Units with software that can transfer data from the unit to a PC can be used to gather more data than it can hold. So depending on how much map data and information you wish to store, you can select the units with the required memory space. You get various models with wide range of built-in memory space.
1 to 30MB http://www.reviewgist.com/gps-devices-reviews?builtInmemory=1-to-30
30 to 512MB http://www.reviewgist.com/gps-devices-reviews?builtInmemory=30-to-512
512 to 2500MB http://www.reviewgist.com/gps-devices-reviews?builtInmemory=512-to-2500
2500 to 40000MB http://www.reviewgist.com/gps-devices-reviews?builtInmemory=2500-to-40000
Antennas
External antennas are used when stronger signals are needed. If in a vehicle the system cannot be placed near the window, external Antenna hookups can prove to be ideal solution. Choice of external hookups is most practical for hiking under heavy tree cover, under tall buildings or in any place which doesn’t have a good view of sky. GPS devices with external antenna hookup can be found at: http://www.reviewgist.com/gps-devices-reviews?antenna=External+Antenna+Hookup
Built-in antennas are less prone to breakage and can communicate with more satellites. Some such devices are available at:
http://www.reviewgist.com/gps-devices-reviews?antenna=Built-in
Quadrifilar Helix- This is also an external antenna useful for situations where open sky is limited. Check the models at:
http://www.reviewgist.com/gps-devices-reviews?antenna=Quadrifilar+Helix
Flip up antennas too give strong performance. Some such models are at: http://www.reviewgist.com/gps-devices-reviews?antenna=Flip-up
Price
This is one factor not to be compromised on, if you don’t wish yourself or your loved ones to get lost in the maze of roads. The technology in this field has developed rapidly and the old models which are cheaper may have crowded maps, or confusing menu options. Latest models high on price have more detailed maps. Of course, lesser the features lesser will be the cost. If you don’t need features like live traffic data or weather data, don’t invest money in models offering these features. Features like speech recognition for hands free operation, 3D maps, and information on fuel prices all come for additional price.
Under $200- http://www.reviewgist.com/gps-devices-reviews?Price=59.5-to-199.99 You get good light weight portable navigation units in this range. Maps look great with reasonably timely route recalculations. Good value for money! Those of you looking for more memory space may check out models at higher range.
Between $200 to $312- You get better performance and features like anti glare, touch screen with good resolution. You also get good in-built memory space and battery life. http://www.reviewgist.com/gps-devices-reviews?Price=199.99-to-311.99
Between $312 to $416- Good screen settings, voice guided directions and overall good performance. http://www.reviewgist.com/gps-devices-reviews?Price=311.99-to-415.45
Between $416 to $1172- Accurate route guidance, easy to use and compatibility with Bluetooth cell phones are some attractive features of devices in the price range. http://www.reviewgist.com/gps-devices-reviews?Price=415.45-to-1171.78
Brands
There are various manufacturers manufacturing GPS units with different features to suit a wide range of customers. The major brands available today are:
Garmin has many models of handheld and mounted types. Check its models at: http://www.reviewgist.com/gps-devices-reviews?BrandName=Garmin

Digital video camcorders have made shooting and editing a movie a simple affair for many. A decade back, one had very limited options, not so anymore! You head to buy one and you find the counters are flooded with various models of digital camcorders from different manufacturers, each with an array of features and formats. Now comes the most difficult part: choosing the one that rightly fits your purpose and budget.
The following sections are intended to guide you through the maze of models and help you select one that suits you the most.
Camcorder Type
Of the two types, analog camcorders and digital camcorders, digital camcorders are a rage today. The analog camcorders are too cumbersome, complicated and heavy to handle. Hence these analog models are fast getting replaced. Recording the information digitally on to a tape or DVD or hard disk and repeatedly playing them without any loss in quality are the major plus points of digital camcorders. They produce excellent quality, color and clarity of the video with 500 lines of resolution making the option of shooting videos with digicams irresistible. Check the models at:
http://www.reviewgist.com/camcorder-reviews?camcorderType=Digital
Key Features
Let’s have a glance at the key camcorder features. This will help you understand, which of them you would actually serve your purpose.
Screen Size
Bigger the screen size, the more you can see of what you are recording. At the same time it will draw more battery power too. If you intend shooting frequently in bright sunlight, an additional feature the viewfinder will be very helpful and power saving too. There are various models with different panel sizes. You can have a look at the various models in these sizes:
1.8 to 2.4 in.: http://www.reviewgist.com/camcorder-reviews?lcdPanelSize=1.8-to-2.4
2.4 to 2.7 in.: http://www.reviewgist.com/camcorder-reviews?lcdPanelSize=2.4-to-2.7
2.7 to 3 in.: http://www.reviewgist.com/camcorder-reviews?lcdPanelSize=2.7-to-3
3 to 3.5 in.: http://www.reviewgist.com/camcorder-reviews?lcdPanelSize=3-to-3.5
Zoom
There are two distinct zoom capabilities digital and optical zooms and most camcorders have both.
Digital zoom enlarges the image i.e. it magnifies the actual pixels to achieve the maximum zoom. The final image is thus grainy in certain sections and lack clear definition. This blurring of picture due to enlargement of pixels is called pixelation. Most camcorders have the option to turn it off. It is not a very quality feature and you can afford to ignore it when purchasing a camcorder. A high digital zoom rating is impressive in figures but the images recorded are virtually useless. Check out the models in the various digital zoom ranges.
6.3 to 200: http://www.reviewgist.com/camcorder-reviews?digitalZoom=6.3-to-200
200 to 1000: http://www.reviewgist.com/camcorder-reviews?digitalZoom=200-to-1000
1000 to 2000: http://www.reviewgist.com/camcorder-reviews?digitalZoom=1000-to-2000
Optical zooms use physical movement of lens mechanism. The focal length of the lens is changed and the entire image that passes through the lens is captured with optical zoom. Thus it is more preferred. Higher optical zoom rating gives better image quality.
http://www.reviewgist.com/camcorder-reviews?opticalZoom=8.3-to-16
http://www.reviewgist.com/camcorder-reviews?opticalZoom=16-to-35
Recording Formats
Many recording formats are available. Each type of cassette or disc records video using a particular standard. Some of the commonly used formats are mentioned below:
MiniDV- MiniDV cassettes are the most commonly used. The video and sound quality is exceptionally good. These are mostly integrated in mid-range and high range models. The MiniDV camcorders are small, sleek and stylish owing to the small size of MiniDV cassettes.Some models at: http://www.reviewgist.com/camcorder-reviews?recordingFormat=Mini+DV
DVD- The three types of DVD formats are: DVD-R, DVD-RW, and DVD-RAM. With DVD camcorder you can record video directly to a DVD-R and DVD-RW. With DVD-RAM camcorders in-camera editing is possible. DVD camcorders are expensive, but the associated advantage is that even with repeated playbacks the disc doesn’t degrade.
http://www.reviewgist.com/camcorder-reviews?recordingFormat=DVD
Flash Media- You can record digital stills to the Flash Media card just as it is done in digital cameras. Very few camcorder models record video to a flash media card. The various Flash Media cards used by the various manufacturers are: SD, Compact Flash, Memory Stick and Memory Stick Duo. http://www.reviewgist.com/camcorder-reviews?recordingFormat=Flash+Media
HDD- HDD camcorders are compact and record in MPEG-2 encoded video and also in other encoded formats too. Huge amounts of video data can be stored using compression techniques. The video is saved to an internal hard disc, the data has to be downloaded to a computer, and then burnt in to a DVD; the camcorder is then ready for reuse. HDD camcorders have no moving parts, hence the recording is free of motor noise and there is less chance of mechanical breakdown. http://www.reviewgist.com/camcorder-reviews?recordingFormat=HDD
HDV-High Definition Video- The images are recorded to MiniDV tapes and deliver 1080i resolution. The sharp, clear video looks great on 1080i capable HDTV. In case you are editing HD video the prerequisites are the computer must have a fast processor, plenty of memory to meet the requirements of video editing software. http://www.reviewgist.com/camcorder-reviews?recordingFormat=HDV
Digital 8- The Digital 8 camcorders record digital video on to Hi-8 video tapes. These camcorders can playback analog video tapes recorded on Hi-8 camcorders. The picture quality is very good and can be viewed on your television. http://www.reviewgist.com/camcorder-reviews?recordingFormat=Digital-8
Micro MV- MicroMV camcorders use tapes that are much smaller than MiniDV tapes and use a compression technology. The digital video is compressed much more than a MiniDV camcorder. The MicroMV camcorders record high quality video and are equipped with full digital editing capability. These are ultra compact, light weight and amazingly small size that can fit in your palm. And they sure do come with heftier price tags. http://www.reviewgist.com/camcorder-reviews?recordingFormat=Micro+MV
Image Stabilization
For shooting a good video, you need to hold the camcorder steady and it should be jerk free. Camcorders have in built stabilization techniques which rectify errors caused due to jerks while shooting. The two types of stabilization techniques are Optical method and the Electronic method.
In the Electronic image stabilization technique the camcorder’s internal computer shifts the image electronically in the opposite direction of the shake. This is achieved by slightly zooming in on the image. Poor electronic techniques can cause loss of sharpness or resolution.
In the Optical image stabilization technique, a part of the lens is moved in the camcorder to compensate for the shake. This technique is superior to electronic method.
The best way to get a stable video shoot would be to use camcorder with tripod.
Controls
A small compact camcorder is convenient to carry no doubt but check out whether it is convenient for you to handle the controls too. Don’t compromise on usability. If you are able to see and operate all the main controls with less hassle, it will be easy for you to get the desired pictures.
Batteries
The LCD monitor of camcorders consumes huge amounts of power. So to keep the camcorder going when you are recording those crucial moments high capacity batteries are recommended. Rechargeable batteries are the best options. The most common ones used are NiCd and Lithium ion batteries. Of the two, Lithium ion batteries are preferred as they can be charged quickly and they are lighter than others. Lithium ion batteries score over NiCd batteries over the fact that they do not have the memory effects that reduce the effectiveness over time. Most batteries have a life period of around six hours. Check at: http://www.reviewgist.com/camcorder-reviews?batteryLife=0.58-to-6.4 however if you are keen in longer lasting batteries, check http://www.reviewgist.com/camcorder-reviews?batteryLife=6.4-to-150 .
Cost Factor
The low priced ones are of older technology. It is easy to record and also play them back. You get reasonably good results. Various manufacturers are in the fray with these digital camcorders. If shooting videos is your new passion low cost ones are ideal to get the hang of it. Low priced models at:
http://www.reviewgist.com/camcorder-reviews?Price=0.01-to-239.9
For editing the recordings, adding sound tracks and effects the camcorders are priced more. The models in this mid range come with better features, more manual options and are also capable of taking good resolution still images. Check out some of the models in this range:
http://www.reviewgist.com/camcorder-reviews?Price=239.9-to-595.8
http://www.reviewgist.com/camcorder-reviews?Price=595.8-to-1404.39
High priced camcorders needn’t always mean they are most suited to your needs. They are the latest in the market with a newly added feature and only few companies have monopoly over this latest technology. So before you invest in one check out how best it is suited to your needs. If you are looking for quality with high resolution and flexible digital editing capabilities spend more. With more money you are going to get more features and thus more quality videos. Some of the models in this high range of $1404.39 to $23277.99 are at:
http://www.reviewgist.com/camcorder-reviews?Price=1404.39-to-23277.99

Notebook shopping can be rewarding provided you are literate about the various features that various manufacturers offer. Popularity of notebook has soared more because of its portability without any compromise on performance. Since buying a notebook can be once in few years affair you need to be clear about its use.
Following is a condensed notebook buying guide dealing with just the main factors you need to keep in mind before purchasing one.
The need of the hour today is to carry work and information and instant access to internet to present information for sales and clinch business deals. So obviously the size and weight of the notebook you carry around matters a lot. Notebooks are categorized both on basis of weight and on basis of screen size.
The four basic sizes are:
Tablet PCs have all the normal functions. There is the added advantage of being able to physically write and manipulate applications with a specially designed input device- the Pen. The two types are the slate and the convertible. Example: Lenovo ThinkPad X41 2526, Lenovo ThinkPad X41 (S5519073) PC Notebook . More at- http://www.reviewgist.com/notebook-tablet-reviews
Ultra portable notebooks are extremely light with small keyboards and screen. There is however no compromise on emailing and web surfing capabilities and can connect to cellular broad band wireless providers. The CD/DVD drives are removed to save space. Lenovo ThinkPad X60 Ultraportable
Thin and light notebooks weigh five to seven pounds. The swappable media bays make it possible to switch between CD/DVD and spare battery. You will have to recharge often else carry the power adapters too. Lenovo ThinkPad X60s (X60s_Standard_Ultralight)_BT…) PC Notebook
Desktop replacements are powerful notebooks, only that you won’t be able to carry it around much. Available with powerful processors, adequate memory, plenty of drive space and wireless connectivity. The negative factor associated being comparatively lesser battery life due to power draining screens and the powerful components.
The travel weight specified must include the weight of power adapters and media bays but most manufacturers mention just the weight of the system and its batteries. Check out the models in the following three ranges:
0.6 to 4 lb. Most ultra portables come in this range. – http://www.reviewgist.com/notebook-reviews?weight=0.6-to-4
4.1 to 5.7 lb. Thin and light models with reasonably good battery life. – http://www.reviewgist.com/notebook-reviews?weight=4.1-to-5.7

Notebook displays come in thin film transistor Liquid Crystal Display (LCD) models, perfectly flat and just half an inch thick, as they are easily portable. Specifications state TFT Active Matrix Display or LCD Display. If you are a frequent traveler, a good combination of small size and less weight will be easier for you to carry around. In case you wish to view movies bigger displays will well serve the purpose. Check out the three commonly available sizes.
8.9 to 11.1 inches- most of them have smart designs and good battery life, but reduced video quality limits its uses- http://www.reviewgist.com/notebook-reviews?displaySize=8.9-to-11.1
12 to 14 inches- good for watching movies and for gaming http://www.reviewgist.com/notebook-reviews?displaySize=12.1-to-14
14.1 to 17 inches- for gorgeous display and powerful performance, so, ideal for business presentations- http://www.reviewgist.com/notebook-reviews?displaySize=14.1-to-17
Display resolution
Displays have another criterion which needs scrutiny before purchase. It is the display resolution- higher the resolution cleaner and crisper will be the image. Resolution is number of pixels across the width and height of screen. 1024 x 768 means 1024 pixels across the height and 768 pixels across the width. Pixels mean the individual dots that make up the picture.
In specifications the standard screen and widescreen is specified with abbreviations as XGA, SXGA, WXGA, WSXGA or WUXGA. The widescreen are fast becoming the rage because the reading space increases more with slight increase in size.
1024 x 768 Small displays 12.1 in. usually have this resolution XGA (1024 x 768), WXGA resolutions (1280 x 800). Larger screens too come with so low resolutions and they are cheap and ideal for budget computers. – http://www.reviewgist.com/notebook-reviews?displayMaxResolution=1024+x+768
1400 x 1050 Many large displays 12.1 and 15 inches come with this resolution like SXGA+ (1400 by 1050) and give very good picture quality. – http://www.reviewgist.com/notebook-reviews?displayMaxResolution=1400+x+1050
1920 x 1200 Models with such resolution WUXGA (1920 x 1200) is ideal for making movies as there is more detail in the image and more work space on the display. However a negative factor associated with such high resolution is that the fonts tend to be smaller, difficult to read especially for people with poor eyesight. This factor is corrected by changing the font size in operating system but the correction can have unintended effects on other programs. – http://www.reviewgist.com/notebook-reviews?displayMaxResolution=1920+x+1200
Display screens
The screen is of two types Glossy and Matte. Glossy screens have the advantage of reduced screen door effect i.e. reduced black spaces between pixels, thus improving the contrast and brightness of the image. The disadvantage is the reflective ness causing eye strain. Matte screens don’t have this feature and are a lot cheaper than glossy ones. The brightness of LCD screen can be adjusted and a lower setting can help conserve power. The brightness is adjusted by adjusting the intensity of the back light inside the panel that illuminates the screen.
This is the most important feature of notebook. There are types of processors and subtypes of processors. Sub-types being ultra low voltage, low voltage, and normal chips of say Pentium M or Intel Core Solo. Low voltage processors give good battery life. So depending on the ultimate application you intend to use the specifications will vary. Since notebooks cannot be easily upgraded (any upgrade of CPU would require dismantling the system to the core and replacement of motherboard, RAM, and may be add another heat sink.) it will be worth the money if you spend enough for fast processors to satisfy your current and future requirements. No single processor can fit all needs and functions, it may be ideal for single function but not for all tasks.
Processor brands
Two of the leading companies manufacturing processors used in notebooks are AMD and Intel. The processor market is entirely in the grip of these two companies. The clock speed of single core versions of the processors produced has touched the upper limit. These single core processors develop heating problems when multiple functions are carried out. Both Intel and AMD have developed the dual core technology in its processors that has increased the multitasking capabilities of notebook PCs.
Intel uses the SpeedStep technology which senses and reduces frequency and power consumption if power is drawn from battery and increases the same if power is drawn from external source. AMD features PowerNow for the same purpose.

Intel - http://www.reviewgist.com/notebooks-reviews?processorManufacturer=Intel .
Knowledge of the processor type will be handy to install the correct packages. Some processor types in notebooks are:
AMD processors are http://www.reviewgist.com/notebook-reviews?processorManufacturer=AMD&processorType=Athlon+XP-M
http://www.reviewgist.com/notebook-reviews?processorManufacturer=AMD&processorType=Mobile+Sempron
Intel processors are Celeron M- http://www.reviewgist.com/notebook-reviews?installedRAM=512-to-2048&processorType=Celeron+M
Pentium 4- http://www.reviewgist.com/notebook-reviews?installedRAM=512-to-2048&processorType=Pentium+4
Core Duo- http://www.reviewgist.com/notebook-reviews?installedRAM=512-to-2048&processorType=Core+Duo
Core 2 Duo- http://www.reviewgist.com/notebook-reviews?processorManufacturer=Intel&processorType=Core+2+Duo
Processor speed is another factor to be considered. The one you would use for just surfing and as a letter box would be cheaper and slower, while heavy duty multitasking, running multimedia applications require faster processor and cost more.
1.1 to 1.5 GHz- A do everything notebook processor like creating and sharing documents, net browsing, send and receive mails, write or receive text messages, make phone calls etc. Check http://www.reviewgist.com/notebook-reviews?processorSpeed=1.1-to-1.5
1.6 to 2.1 GHz the double core processors with this speed give good performance and long battery life. – Check http://www.reviewgist.com/notebook-reviews?processorSpeed=1.6-to-2.1
2.2 to 3.3 GHz The dual core CPUs are the fastest. Programs run faster with such fast processors, they cost more too. Recording videos, playing extremely high definition videos, touching up digital photos, video editing all require fast processors. These fast processors consume more power especially when used in portables. Check http://www.reviewgist.com/notebook-reviews?processorSpeed=2.2-to-3.3
The memory requirements depend on OS and the applications you plan to put in use. RAM is used to process the program information. More is always better for faster loading, printing and down loading of your files. Buy the ones that have easy to access memory slots as you would very soon want to upgrade this feature. There are two ranges of RAM available.
128 to 256 MB- this space can manage your daily mails and normal applications check at http://www.reviewgist.com/notebook-reviews?installedRAM=128-to-256
512 MB to 2048MB for improved performance check at http://www.reviewgist.com/notebook-reviews?installedRAM=512-to-2048
A memory specification like 512 MB (DDR2 SDRAM) indicates; the space is 512 MB, DDR2 (double data rate 2 synchronous dynamic random access memory) is the memory type, latest widely used one. DDR2 is the new version of DDR. Speeds are assigned by the memory type and clock rating and another method by bandwidth.
Drives
Drives provide the storage for the computer programs. Again this choice depends on how much data you wish to store. Some laptop models come with swappable drives which increases the flexibility.
Drives have three specifications: size, type of interface and speed. Notebook hard drives come in two sizes; 1.8 inch and 2.5 inch. The 1.8 inch ones are mostly in ultra portables, while the 2.5 inch size Hard Drives are used commonly in other notebooks. IDE and Serial ATA are the two types of connectors between hard drives and computer and of the two it is IDE which is more commonly used. Speed at which the hard drive spins also determines the performance. Most notebook hard drive spins at 5400 rpm speed. A higher spin rate of 7200 rpm gives better performance but uses more power.
Following is categorization based on storage space.
1 to 31GB-Mostly incorporated in low cost budget notebooks. http://www.reviewgist.com/notebook-reviews?hardDriveCapacity=1-to-31
40 to 80GB- Home users using notebooks for photos and videos, in addition to normal surfing can opt for 80 GB hard drives. http://www.reviewgist.com/notebook-reviews?hardDriveCapacity=40-to-80
100 to 256GB- Most multimedia notebooks have dual hard drives of 200 to 320 GB. For gaming uses 100 GB should suffice. http://www.reviewgist.com/notebook-reviews?hardDriveCapacity=100-to-256
The battery life definitely depends on the chores or tasks that are carried out; some of them being the applications like MS Office, Norton AntiVirus programs, Netscape. Huge amount of power is consumed for displaying images on the screen. The rest of the system like the core-logic, chip set and memory too draws power. Notebooks designed to handle large power consumption weigh more as they come with large batteries and thermal heat sinks.
If you are traveling too frequently go for batteries that have longer run time or purchase two of them and use both of them equally. Prefer the notebooks equipped with lithium-ion rechargeable batteries. Check with dealer for battery settings and battery backup so that it lasts long. Normally batteries can last 700 charging cycles.
Check the following three categories of battery run time:
1.5 to 3 hrs-great for viewing movies, video chats and photos at home, viable for budget desktop replacement. http://www.reviewgist.com/notebook-reviews?batteryRunTime=1.5-to-3
3.1 to 4.3 hrs- http://www.reviewgist.com/notebook-reviews?batteryRunTime=3.1-to-4.3
4.4 to 12 hrs- http://www.reviewgist.com/notebook-reviews?batteryRunTime=4.4-to-12
These systems have high flexibility, more durability and security features. Business laptops use stronger materials and lighter cases, more mobility features like lightweights and wireless options. There are plenty of hardware features and software to choose from to configure to your business requirements. Check this link: http://www.reviewgist.com/business-notebooks-reviews
These are available for less than $1000USD with a lot of compromise on speed, storage and convenience. So depending on what you wish to use it for, decide what tradeoffs are acceptable to you. A 100GB hard drive, fifteen inch screen, a DVD/CD combo drive which can be upgraded and connection ports should come within a reasonable budget. Check the following brands in the price range of 162.3 to 912.5 $:
IBM- http://www.reviewgist.com/notebook-reviews?BrandName=IBM&Price=162.3-to-912.5
HP Compaq- http://www.reviewgist.com/notebook-reviews?BrandName=HP+Compaq&Price=162.3-to-912.5
Dell- http://www.reviewgist.com/notebook-reviews?BrandName=Dell&Price=162.3-to-912.5
These use fastest processors with powerful video cards, ideal for gaming, has good graphics and faster speeds. The gaming version can be for 3D games, wide-screen HDTV, and video editing studio and for dynamic presentations. While purchasing one consider the graphics, RAM and processors with highest speed. Lenovo ThinkPad T60p (200783U) PC Notebook, Toshiba Satellite A65-S126
Must haves are good portability, performance, battery life, light weight. A thin and light or ultra portable should fit the bill. It may be used for office applications and gaming purpose. Lenovo ThinkPad X60s (X60s_Standard_Ultralight)_BT…) PC Notebook. Check for light weight notebooks at http://www.reviewgist.com/notebooks-reviews?weight=0.6-to-4
Weight may not be major criteria. You may be using this for after trips video editing, storing pictures, and may be exchange information. You may wish for a large screen and 512MB memory, in a mid-range budget. Consider the following recommendations:
Brand Lenovo- http://www.reviewgist.com/notebook-reviews?BrandName=Lenovo&Price=937.8-to-1258&displaySize=15-to-15.4&installedRAM=256-to-512
Brand Toshiba- http://www.reviewgist.com/notebook-reviews?BrandName=Toshiba&Price=937.8-to-1258&displaySize=15-to-15.4&installedRAM=256-to-512
These are an all in one item. Serves as television, digital video recorder, mobile DVD player, MP3 juke box, digital photo album. Battery life of three hours so can be taken on vacation but definitely not for frequent travelers. Some models can boot to non-Windows environment to play audio CDs even when the system is off. It will require high speed processors and cost more too. Lenovo ThinkPad T60p (200887U) PC Notebook, Acer Ferrari 3200 (lxfr206001) PC Notebook
Everything ultimately depends on how much you intend to shell out from your pocket. Following are the three price ranges which will help you select the desired model with desired features.
