Parts of a computer (all that we have learnt)

Static Wristband: It goes around you wrist and is clipped to the case while you put the computer together. If you don't do so then the static electricity will go from your body and damage the computer parts.

Power Supply: The power supply has a cord that plugs into and electrical outlet that sends electricity to the rest of the computer.

RAM: It stands for random access memory. This is where your computer stores your data while it runs your programs. When your computer shuts down then it deletes all the data stored in it.

Central Processing Unit: This is the brain of your computer. It runs a program by performing a series of simple instructions. This includes managing the movement of the data through the motherboard.

Fan: The fan keeps the processor from overheating.

Disk Drive: It is a laser that reads the CD’s/ DVD’s

Hard drive: This is where all the data (Documents/ Pics/etc..) is stored. Unlike the RAM it saves the data even after the computer is shut down.

Motherboard: It connects the RAM, processor, and hard drive together and lets them communicate and work together.

Case: The case houses all the parts and protects them from hazards like bumps and dust.

Graphics Card: A graphics card, also known as a video card, is a piece of hardware installed in a computer that is responsible for rendering the image on the computer’s monitor or display screen. The images you see on you are made of tiny dots called pixels. At most common resolution settings, a screen displays over a million pixels, and the computer has to decide what to do with everyone in order to create an image and this job is done by a graphics card. A graphics card must work very hard to render images to the screen. Unlike text files, graphics images are much larger files consisting of great amounts of data that must be processed by the graphics or video card.

Disk Array Controller: A disk array is a hardware element that contains a large group of hard disk drives (HDDs). It may contain several trays and has an architecture which improves speed and increases data protection. The system is run via a storage controller, which coordinates activity within the unit. Disk arrays form the backbone of modern environments. A storage area network contains one or more disk arrays that function as the source for the data which is moved in and out of the SAN.

PCB: PCB’s (Printed circuit board) or adapters come in tows, the sound card and the video graphics card. They enhance the sound and video quality of the computer. It is also the skeleton of most electronic devices. It provides not only a solid physical base for the components to be mounted upon, but also the electrical interconnects (traces) between the components.
