PARTS OF THE COMPUTER

NAME	IMAGE	FUNCTIONS
MONITOR		A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display, support electronics, power supply, housing, electrical connectors, and external user controls.
KEYBOARD		A computer keyboard is an input device used to enter characters and functions into the computer system by pressing buttons, or keys. It is the primary device used to enter text. A keyboard typically contains keys for individual letters, numbers and special characters, as well as keys for specific functions.
MOTHERBOARD		The motherboard is the backbone that ties the computer's components together at one spot and allows them to talk to each other. Without it, none of the computer pieces, such as the CPU, GPU, or hard drive, could interact. Total motherboard functionality is necessary for a computer to work well.
MOUSE		A computer mouse is a handheld hardware input device that controls a cursor in a GUI (graphical user interface) for pointing, moving and selecting text, icons, files, and folders on your computer.
SPEAKER		A computer speaker is an output hardware device that connects to a computer to generate sound. The signal used to produce the sound that comes from a computer speaker is created by the computer's sound card.
CPU(Central Processing Unit)		The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which data to process and how to process it. Without a CPU, we could not run programs on a computer.
MAIN MEMORY OR MEMORY		Main memory holds instructions and data when a program is executing, while auxiliary memory holds data and programs not currently in use and provides long-term storage
EXPANSION BUS		An expansion bus provides an input/output pathway for transferring information between internal hardware, such as RAM or the CPU, and expansion devices such as a graphics card or sound card.
ADAPTERS A.LAN CARD B.SOUND CARD C.VIDEO CARD		An adapter card (also known as an expansion card) is simply a circuit board you install into a computer to increase the capabilities of that computer.
POWER SUPPLY UNIT		Specifically, a power supply converts the alternating high voltage current (AC) into direct current (DC), and they also regulate the DC output voltage to the fine tolerances required for modern computing components.
HARD DISK DRIVE(HDD)		A hard drive is the hardware component that stores all of your digital content. Your documents, pictures, music, videos, programs, application preferences, and operating system represent digital content stored on a hard drive. Hard drives can be external or internal.
OPTICAL DRIVE		An optical disc drive (ODD) in a computer system allows you to use CDs, DVDs, and Blu-ray discs to listen to music or watch a movie. Most drives also allow you to write data to a disc, so you can create your own music CDs, video DVDs or even create of back-up copy of your important data files.
CPU Fan and Heat sink		A heat sink and fan is often used in modern computer systems to keep the processor cool. Without it, the processor could easily overheat and become damaged. Therefore, this combination is often found in most low- to mid-range computer systems, and even in high-end notebooks.
EIDE(Enchanced Integrated Drive Electronics)data cable		EIDE cables are used to connect older-style PATA hard drives and other PATA devices such as optical drives, tape drives, or ZIP drives to the computer's motherboard. Traditionally, IDE cables were flat, gray, ribbon-type connectors. Older (ATA-33) IDE cables had 40 conductors and forty pins.
SA-TA data cable		SATA data cables are used to connect storage devices to your computer's motherboard ("mobo") or SATA controller.
