| LCDs are free from geometric image distortions at the screen edges because they are a flat matrix display where every pixel is active. CRT s are subject to peripheral distortion of the image as the electron beam becomes progressively more tangential to the monitor screen phosphors at the edges, hence CRT screens typically have a black dead space around them. |
| LCD s are free from flicker because they do not rely on a scanning electron beam. CRTs are more prone to flicker. |
| Notebook is very handy and can easily be transported and conveniently used in temporary spaces such as in class rooms, in libraries, temporary offices, and at meetings. It can be used while you are on plane or navigating through ship. Notebook computer is a small computer that can be tuck into a handbag or briefcase to carry anywhere, in shopping, meetings or even in vacations. You can carry your notebook to class and take note the important points in the discussion directly into your notebook. |
| You can see the actual computer in action here before you pay and you can take it back for a full refund if not functioning well. The computer here comes with complete operating system and some bundled software and has easy payment terms. But commonly the staff at these stores may have limited knowledge and could give you a wrong information. |

| Your Need and Purpose will determine the SIZE. Below are the group of laptop or notebook computer that are categorized according to its SIZE. |
 | A camera connected to a computer or server that allows anyone connected to the internet to view still pictures or motion video of a user. The term webcam is also used to describe the low-resolution digital video cameras designed for such purposes, but which can also be used to record in a non-real-time fashion. . |
 | A hardware device that enables an image, such as a computer screen, to be projected onto a flat surface. All video projectors use a very bright light to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings. Video projectors are widely used for video conference, room presentations, classroom training, and home theatre applications. |
 | Also known as a graphics card, graphic adapter, video board, video controller, video adapter is an internal circuit board that allows a display device, such as a monitor, to display images from the computer. It operates on similar principles as a sound card or other peripheral devices. The term is usually used to refer to a separate, dedicated expansion card that is plugged into a slot on the computer's motherboard. |
 | Uninterruptible Power Supply, UPS is a hardware device that provides a backup power source in case of a power outage (blackout), brownout, or a surge in power. A UPS provides enough power for the computer or computers to shut down properly or to remain up during a temporary power outage. Typically, a UPS keeps a computer running for several minutes after a power outage, enabling you to save data that is in RAM and shut down the computer gracefully. |
 | Also known as a sound board or an audio card, a sound card is an expansion card or integrated circuit that provides a computer with the ability to produce sound that can be heard by the usercanner is commonly connected to a computer USB, Firewire, Parallel or SCSI port. |
 | A Scanner is a computer peripheral device that allows a user to take an image and/or text printed on paper and convert it into a digital file, allowing the computer to read and/or display the scanned object. A scanner is commonly connected to a computer USB, Firewire, Parallel or SCSI port. |
 | The processor is the brain of the computer. It handles all the processes and transactions done by a personal computer. CPU and processor are used interchangeably. CPU or processor is housed in a single chip called microprocessor. |
 | An external hardware device responsible for taking computer data and generating a hard copy of that data. Printers are one of the most used peripherals on computers and are commonly used to print text, images, and/or photos. |
 | Network Card also known as Network Interface Card or NIC, network adapter, LAN Adapter, is a printed circuit board containing the necessary hardware used to connect a computer to a network or other computer. It provide a dedicated, full-time connection to a network. |
 | A mouse is a small device that a computer user pushes across a desk surface in order to point to a place on a display screen and to select one or more actions to take from that position. |
 | A motherboard is a printed circuit board that is the foundation of a computer and allows the CPU, RAM, and all other computer hardware components to function with each other. It is also known as a mainboard, baseboard, system board, and logic board. |
 | A Modem which comes from the word “Modulator/Demodulator” is a device that modulates outgoing digital signal from computer or any digital devices into an analog signal to transmit trough cable or telephone lines and demodulates incoming analog signal from cable or telephones lines into digital signal to be used for any digital devices such as computer |
 | Memory or RAM is the temporary working memory that your computer uses to perform calculations and manipulate files. When you open a document, it is copied from the hard drive into RAM. As you and your word processor work on the file, the modified copy exists only in RAM. When you save the file, it is copied from RAM back to the hard drive, or permanent storage. It is also the place in a computer where the operating system, application programs, and data in current use are kept so that they can be quickly reached by the computer's processor. |
 | LCD Monitors are commonly used in notebook computers and now are most popular for flat panel desktop monitors. It is a flat panel display device that uses rod-shaped molecules called liquid crystals that flow like liquid and bend light. It is often utilized in battery-powered electronic devices because it uses very small amounts of electric power. |
 | A Keyboard is a primary input device that is used mainly for inputting text. Its key-arrangement was patterned from and electronic and mechanical typewriter. |
 | Hard Disk Drive is the mechanism that controls the positioning, reading, and writing of the hard disk, which furnishes the largest amount of data storage for the PC. Although the hard disk drive and the hard disk are not the same thing, they are packaged as a unit and so either term is sometimes used to refer to the whole unit. There are several interface standards for passing data between a hard disk and a computer. The most common are IDE and SCSI. |
 | DVD-RW is a rewritable optical disc which has a typical storage of 4.7 gigabytes. Its primary advantage is its ability to erase and rewrite data. It is most suitable for volatile data such as back ups or collection of files. One advantage also of using this disc is if there are writing error in recording data, the disc can be reused again by erasing the faulty data. |
| DVD-ROM is an optical disc storage that is capable to store atleast 47.7gigabytes. DVD-ROM has data which can only be read but cannot be written over. It has the same size and form with CD-ROM |
 | CD-RW(Compact Disc ReWritable) is a rewritable optical disc. It enables you to write over it many times. |
| CD-ROM (Compact Disc-Read-Only Memory) is an optical disk use for storing large amount of data, the most common is 650 Megabytes. CD-ROMs are popularly used to distribute computer software, including games and multimedia applications, though any data can be stored (up to the capacity limit of a disc). |
 | A desktop computer is a personal computer that is designed to fit conveniently on top of a typical office desk and comes in a variety of case styles ranging from large vertical towers to small form factor models that can be tucked behind an LCD monitor. Desktop computer is used in businesses, schools, and households. It is used for performing office tasks, organizing digital photos, video editing, gaming and Internet access. |
 | Notebook computer, commonly called laptop computer, is a personal computer generally equal or smaller than a briefcase. It is very handy and can easily be transported and conveniently used in temporary spaces such as in class rooms, in libraries, temporary offices, and at meetings. It can be used while you are on plane or navigating through ship. Notebook computer is a small mobile computer, which usually weighs 2-18 pounds depending on size, materials used to make it. |
