What are the main parts of the computers and their functions?

Answer 1

1. Monitor:

A monitor displays information in visual form, using text and graphics. The portion of the monitor that displays the information is called the screen. Like a television screen, a computer screen can show still or moving pictures.

2. CPU:

The central processing unit (CPU), or microprocessor, which acts as the "brain" of your computer. Another component is random access memory (RAM), which temporarily stores information that the CPU uses while the computer is on. The information stored in RAM is erased when the computer is turned off.

Almost every other part of your computer connects to the system unit using cables. The cables plug into specific ports (openings), typically on the back of the system unit. Hardware that is not part of the system unit is sometimes called a peripheral device or device.

3. Keyboard:

A keyboard is used mainly for typing text into your computer. Like the keyboard on a typewriter, it has keys for letters and numbers, but it also has special keys:

• The function keys, found on the top row, perform different functions depending on where they are used.

• The numeric keypad, located on the right side of most keyboards, allows you to enter numbers quickly.

• The navigation keys, such as the arrow keys, allow you to move your position within a document or webpage.

• You can also use your keyboard to perform many of the same tasks you can perform with a mouse.

4. Harddisk:

Your computer's hard disk drive stores information on a hard disk, a rigid platter or stack of platters with a magnetic surface. Because hard disks can hold massive amounts of information, they usually serve as your computer's primary means of storage, holding almost all of your programs and files. The hard disk drive is normally located inside the system unit.

5. Mouse:

A mouse is a small device used to point to and select items on your computer screen. Although mice come in many shapes, the typical mouse does look a bit like an actual mouse. It's small, oblong, and connected to the system unit by a long wire that resembles a tail. Some newer mice are wireless. A mouse usually has two buttons: a primary button (usually the left button) and a secondary button. Many mice also have a wheel between the two buttons, which allows you to scroll smoothly through screens of information. When you move the mouse with your hand, a pointer on your screen moves in the same direction. (The pointer's appearance might change depending on where it's positioned on your screen.) When you want to select an item, you point to the item and then click (press and release) the primary button. Pointing and clicking with your mouse is the main way to interact with your computer.

6. Printer:

A printer transfers data from a computer onto paper. You don't need a printer to use your computer, but having one allows you to print e‑mail, cards, invitations, announcements, and other materials. Many people also like being able to print their own photos at home.

7. Speakers:

Speakers are used to play sound. They may be built into the system unit or connected with cables. Speakers allow you to listen to music and hear sound effects from your computer.

8. Modem:

To connect your computer to the internet, you need a modem. A modem is a device that sends and receives computer information over a telephone line or high-speed cable. Modems are sometimes built into the system unit, but higher-speed modems are usually separate components.

9. Floppy Disk Drive:

Floppy disk drives store information on floppy disks, also called floppies or diskettes. Compared to CDs and DVDs, floppy disks can store only a small amount of data. They also retrieve information more slowly and are more prone to damage. For these reasons, floppy disk drives are less popular than they used to be, although some computers still include them.

Answer 2

Power Source-provides electricity to components

CPU-the processor, it is the computer's "brain"

RAM-Random Access Memory-holds data for immediate use

Hard Drive-stores data long-term

Video Card-provides video output to the monitor

Disk Drive-reads CD's data

Answer 3

The main parts of a computer are the HDD ( storage of data), Motherboard, CPU and Memory (management), Power supply, ( multi-purpose tasks) Slots to install audio and Video graphics, CD driver(multi-purpose tasks)

Answer 4

CPU-central processing unit. Computes all of the basic functions of you computer.

GPU-graphics processing unit. Processes the images that you see on your screen.

RAM-random access memory. The memory used by the computer to store temporary files related to computing.

HD or Hard Drive-the memory of the computer that stores all of your files (music, photos, documents, games)

keyboard-measures the input from your fingers and turns it into type on the screen

mouse-measures the movement of your hand and translates it into the movement of the cursor on your screen

thats all for now...I will try to add more in the future

Answer 5

CabinetThe cabinet is the part of your computer that holds all the parts that make the computer operate. MotherboardThe motherboard is the part of your computer that wires all of the other parts together. Processor (CPU)The processor, or CPU, of a computer is basically the brains of the computer. Hard DriveThe hard drive part of your computer is also called the hard disk. Essentially, it is the part of the computer that stores your information. Display AdapterWhether a graphic card or part of the motherboard, the display adapter is the component of your computer that interprets video signal. RAM (Memory)Random Access Memory, or RAM, is the part of your computer that is used as instant memory. Optical DriveAn optical drive uses light to read and write data. It is the drive you use to burn CDs, DVDs and Blu-Ray discs.
