What is a PROCESSOR?
A central processing unit (CPU), or sometimes simply processor, is the component in a digital computer that interprets computer program instructions and processes data.

What is a HARD DISK DRIVE/HDD?
A hard disk drive (HDD), commonly referred to as a hard drive or hard disk, is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces. Strictly speaking, "drive" refers to a device distinct from its medium, such as a tape drive and its tape, or a floppy disk drive and its floppy disk. Early HDDs had removable media; however, an HDD today is typically a sealed unit with fixed media.

What is RAM?
Pronounced ramm, acronym for random access memory, a type of computer memory that can be accessed randomly; RAM is the most common type of memory found in computers.

What is a SOUND CARD?
A sound card is a computer expansion card that can input and output sound under control of computer programs. Typical uses of sound cards include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation/education, and entertainment (games). Many computers have sound capabilities built in, while others require these expansion cards if audio capability is desired.

What is a TFT?
Short for Thin Film Transistor, a type of LCD flat panel display screen, in which each pixel is controlled by from one to four transistors. The TFT technology provides the best resolution of all the flat-panel techniques, but it is also the most expensive.

What is a DVD?
DVD (also known as "Digital Versatile Disc") is an optical disc storage media format that can be used for data storage, including movies with high video and sound quality. DVDs resemble Compact Discs because their diameter is the same (120 mm or 4.72 inches, or occasionally 80 mm or 3.15 inches), but they are encoded in a different format and at a much higher density.

What is a VGA?
Video Graphics Array (VGA) is an analog computer display standard. VGA was the most recent graphical standard that the majority of manufacturers conformed to, making it the lowest common denominator that all PC graphics hardware supports before a device-specific driver is loaded into the computer. For example, the Microsoft Windows splash screen appears while the machine is still operating in VGA mode, which is the reason that this screen always appears in reduced resolution and color depth.

What is a FLOPPY DISK/DISKETTE?
A floppy disk is a data storage device that is composed of a disk of thin, flexible ("floppy") magnetic storage medium encased in a square or rectangular plastic shell.

What is a Floppy Disk Drive or FDD?
 Floppy disks are read and written by a floppy disk drive or FDD, the latter set of initials should not be confused with "fixed disk drive", which is another term for a hard disk drive.

What is a USB FLASH DRIVE/DISK
USB flash drives are NAND-type flash memory data storage devices integrated with a USB (universal serial bus) interface. They are typically small, lightweight, removable and rewritable.

What is a MEMORY CARD?
A memory card or flash memory card is a solid-state electronic flash memory data storage device used with digital cameras, handheld and laptop computers, telephones, music players, video game consoles, and other electronics. They offer high re-record-ability, power-free storage, small form factor, and rugged environmental specifications. There are also non-solid state memory cards that do not use flash memory, and there are different types of flash memory. They are sometimes called "mem-cards" by gamers and/or techies.

What is a TOUCHPAD?
A touchpad is an input device commonly used in laptop computers. They are used to move the cursor, using motions of the user’s finger. They are a substitute for a computer mouse. Touchpad’s vary in size but are rarely made larger than 20 square centimeters (about 3 square inches). They can also be found in PDA’s. Touchpad’s operate by sensing the capacitance of a finger, or the capacitance between sensors.

What is a KEYBOARD?
A computer keyboard is a peripheral partially modeled after the typewriter keyboard. Keyboards are designed for the input of text and characters and also to control the operation of a computer.

What is a MOUSE?
In computing, a mouse (pluralmice or mouses) functions as a pointing device by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of a small case, held under one of the user's hands, with one or more buttons.

An Optical mouse uses a light-emitting diode and photodiodes to detect movement relative to the underlying surface, rather than moving some of its parts — as in a mechanical mouse.

What is a WEBCAM?
A web camera (or webcam) is a real-time camera (usually, though not always, a video camera) whose images can be accessed using the World Wide Web, instant messaging, or a PC video calling application. 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.

What is USB?
Universal Serial Bus (USB) is a serial bus standard to interface devices. A major component in the legacy-free PC, USB was designed to allow peripherals to be connected using a single standardized interface socket, to improve plug-and-play capabilities by allowing devices to be connected and disconnected without rebooting the computer (hot swapping).

What is GB?
A gigabyte (derived from the SI prefix giga-) is a unit of information or computer storage equal to one billion (short scale, meaning a thousand million) bytes. It is commonly abbreviated GB (not to be confused with Gb, which is used for gigabits)
