Definition and Uses of Computer Peripherals and Devices

Definition:: Computer peripherals are the Devices that are connected to the computer but are not the core computer architecture.

Core Computer Architecture mainly consists of Computer Motherboard, CPU, power supply, and Computer case or Cabinet or Chassis.

You need memory [RAM], Harddisk, and various other Peripheral devices so that your computer functions to its potential.

Computer Peripherals in other terms can be defined as devices that can be easily removed and plugged into a PC system.

Just like a mouse you can remove it at any time and change it with ease…. the same for the keyboard… But on a laptop, it is difficult to remove because it is a built-in case

A printer is a Computer Peripheral Device your PC can function properly without a printer but if you take out the monitor computer system becomes useless.

In other terms we can say that without Computer peripherals devices personal computers can work properly say your PC can work without a Printer or Webcam but if you unplug the CPU from its socket.

Then the computer Becomes Useless.

In other terms we can say that without computer peripherals or devices, PC can work properly say your computer can work without a Printer or Webcam but if you unplug the CPU from its socket.
