WEEK 4 – L4
Inside of a Computer
The Motherboard : The motherboard is the computer's main circuit board. The motherboard connects directly or indirectly to every part of the computer.
CPU or Central Processing Unit : The Central Processing Unit is located inside the computer case on the motherboard. It is often called the brain of the computer.
Hard Disk Drive : The hard disk drive is the data center of the computer. All of your programs are stored here. The hard disk drive is long-term storage where information is stored permanently.
Optical Disc Drive : An optical disc drive is a peripheral device that reads data stored on optical discs. Some drives can only read from discs, but often drives are both readers and burners. CD and DVD drives are common optical drives.
The Memory : RAM (Random Access Memory) is your system's short-term memory. Data is temporarily stored here until you save your work to the hard disk. The more RAM you have, the more things your computer can do at the same time, and the faster your computer performs certain tasks.
Video Card : The video card is responsible for what you see on the monitor. The main function of the video card is to generate and output images to the computer screen.
Sound Card : The sound card, also called an audio card. It lets the computer play sounds through speakers.
Network Card : The network card allows your computer to communicate over a network and connect to the internet.
Power Supply Unit : The power supply unit in a computer converts the power from the wall outlet to the type of power needed by the computer. It sends power through the cables to the motherboard and other components.
