Hard Drive: A hard disk drive (HDD), commonly referred to as a hard drive, hard disk, or fixed disk drive,is a non – voltatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces.

CPU (central proccessing unit): is a description of a class of logic machines that can execute computer programs.

Motherboard: A motherboard is the central or primary printed circuit board(PCB) making up a complex electronic system, such as a modern computer.

Power Supply: A device or system that supplies eletrical or other types of energy to an output load or group of loads is called a power supply unit or PSU.

PCI: Peripheral Component Interconnect, or PCI Standard (commonly PCI), specifies a computer bus for attaching peripheral devices to a computer motherboard.

PCI-Express: (Peripheral Component Interconnect Express) a computer expansion card interface format introduced by Intel in 2004. PCI Express was designed to replace the general-purpose PCI expansion bus, the high-end PCI-X bus and the AGP graphics card interface.

USB (universal serial bus): a serial bus standard to interface devices to a host computer. USB was designed to allow many peripherals to be connected using a single standardized interface socket and to improve the plug-and-play capabilities by allowing hot swapping, that is, by allowing devices to be connected and disconnected without rebooting the computer or turning off the device.

Firewire: is Apple Inc.’s name for the IEEE 1394 High Speed Serial Bus

IEEE 1394: a serial bus interface standard for high-speed communications and isochronous real-time data transfer, frequently used in a personal computer (and digital audio and digital video).

LCD: A liquid crystal display (LCD) is an electro-optical amplitude modulator realized as a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector.

Plasma: plasma display panel (PDP) is a type of flat panel display now commonly used for large TV displays (typically above 37-inch or 940 mm). Many tiny cells located between two panels of glass hold an inert mixture of noble gases (neon and xenon). The gas in the cells is electrically turned into a plasma which then excites phosphors to emit light.

HDMI: High-Definition Multimedia Interface (HDMI) is a compact audio/video connector interface for transmitting uncompressed digital streams.

RAM: Random Access Memory a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. Ram is the most common type of memory found in computers and other devices.

Flash Memory: non-volatile computer memory that can be electrically erased and reprogrammed. It is a technology that is primarily used in memory cards and USB Flash Drives for general storage and transfer of data between computers and other digital products.

AGP: Accelerated Graphics Port is a high-speed point-to-point channel for attaching a graphics card to a computer’s motherboad, primarily to assist in the acceleration of 3D computer graphics.

DVD: Digital Versatile Disc” or “Digital Video Disc” is a popular optical disk storagemedia format. Its main uses are videoand data storage. Most DVDs are of the same dimensions as compact discs (CDs) but store more than six times as much data.
