Definition

Say you just bought a new computer and, with excitement, you unpack it and set it all up. The first thing you want to do is print out some photographs of the last family party. So it's time to head back to the store to buy a printer. A printer is known as a peripheral device.

A computer peripheral is a device that is connected to a computer but is not part of the core computer architecture. The core elements of a computer are the central processing unit, power supply, motherboard and the computer case that contains those three components. Technically speaking, everything else is considered a peripheral device. However, this is a somewhat narrow view, since various other elements are required for a computer to actually function, such as a hard drive and random-access memory (or RAM).

Most people use the term peripheral more loosely to refer to a device external to the computer case. You connect the device to the computer to expand the functionality of the system. For example, consider a printer. Once the printer is connected to a computer, you can print out documents. Another way to look at peripheral devices is that they are dependent on the computer system. For example, most printers can't do much on their own, and they only become functional when connected to a computer system.

Types of Peripheral Devices

There are many different peripheral devices, but they fall

into three general categories:

1. Input devices, such as a mouse and a keyboard 2. Output devices, such as a monitor and a printer

3. Storage devices, such as a hard drive or flash drive

Some devices fall into more than one category. Consider a CD-ROM drive; you can use it to read data or music (input), and you can use it to write data to a CD (output).

Peripheral devices can be external or internal. For example, a printer is an external device that you connect using a cable, while an optical disc drive is typically located inside the computer case. Internal peripheral devices are also referred to as integrated peripherals. When most people refer to peripherals, they typically

1. What are the input devices? Input devices are used to enter data from outside world into primary storage & output devices supply the result of processing from primary storage to users. 2 What is the purpose of a storage hardware ... The purpose of a storage hardware is to store computer instructions. 3. What is expansion slots?

The expansion slots in the rear of the case are specially cut out so the peripherals connected to the motherboard can extend from the case for easy connection to external devices such as printers, monitors and other external devices.

4.What is External memory

External memory is a disk for long-term storage of information, as well as for reading and writing

5. What is output device?

Output device : a display screen, printer, or other device that lets you see what the computer has accomplished.

6. What does Card Reader mean?

"Card reader" is the generic term for an input device that
