Parts of the Computer and their Function
ComputerA machine that processes information and performs computation.
Major Parts of the Computer
CPURAM
Hard Drive Optical DriveMotherboard
Central Processing Unit (CPU)The central processing unit (CPU) processes all of the data that is accessed by the machine. It is a small internal piece that is located beneath the fan. Essentially, the purpose of a CPU is to process instructions through a four-part sequence of fetching, decoding, execution and write-back.
RAM
Random access memory provides a buffer between the hard drive and central processing unit. When files are requested for processing, they transfer from the hard drive to the memory.
Hard Drive
• A hard drive provides permanent storage for the operating system, programs and files on a machine. When files are saved to the hard drive, they are retained through power outages.
Optical Drive
An optical drive is any drive that reads the data through optic technology, such as a laser. These drives can read data from discs.
MotherboardThe motherboard is an underlying circuit board that holds all the computer components together. Computer components, including the CPU, RAM, hard drive and optical drives, plug into the motherboard. This allows the separate components to interact with each other to create a fully functional machine. While each computer part has a unique function, they would be utterly useless without the unifying motherboard.
Different Equipment of the Computer
DesktopMonitor
USB flash driveMouse
SpeakersHeadphonesMicrophone
HubPrinter
ScannerKeyboard
The "box" or case that holds the parts that makes up a computer.
Desktop
Monitor
An output display device (looks similar to a TV) in a computer system. You see information on the monitor's screen
USB Flash
DriveThese can hold
documents, pictures, and music. Some flash drives are also MP3
players.
Mouse A hand-held input device you roll on your desk to point
to and select items on your screen.
When you move the mouse, the
mouse pointer on the screen moves

Speaker
Output device that produces
sound and music when connected to
the computer.
Headphone
Output device for
listening that is held over
the ears by a band worn
on the head.
MicrophoneInput device in which sound
energy is changed into
electrical energy for the sending or recording sound
(your voice).
HubHubs are devices that have many ports into which network cables are plugged. A hub takes the signal from each computer and sends it to all of the other computers through the network.
PrinterA device that produces a
paper copy of the information on your screen.
Projector
Output device for displaying onto a large surface (projection screen) what appears on the computer monitor.
ScannerInput device that reads copy as an image and
digitally records the
image.
Keyboard
The keyboard is an input device designed to enter text,
characters and other commands into a computer or similar device.
Manipulate a Computer
• Point the icon of the “computer” and open it.
• Plug the speaker to the computer and demonstrate the function of the speaker.
• Connect the projector to the computer.• Point a video, open it, plug the speaker
and project it in the white board.
Assignment
Study in advance on how to use the MS word.
