Computers have become integral parts of our lives nowadays. From making presentations, charts, diagrams to gaming, watching movies etc. a single computer could be of much use to us.

Likewise, there are many more peripherals that will be looked at below.
- The keyboard
The keyboard is known as the most important input device. Without this, you cannot give the required commands to the computer. It is used to enter data by the set of keys which have letters, numbers and certain symbols on them. The keyboard is used for several functions by pressing the ‘Ctrl’ key.
- The mouse
This detects two-dimensional motion and will transfer it onto the screen by moving a cursor or mouse-pointer. This peripheral has come a long way, first being introduced with a ball at the bottom so that the cursor would move according to the motion of the ball. This was known as the ball mouse. Then came the modern lightweight laser and optical mice which is much easier to work with. Bluetooth mice was another great innovation since it was wireless. A usual mouse would have two buttons and a wheel in the middle to scroll up and down. However, in a student laptop HK nowadays, the function of a mouse has been replaced by the touch pad. However, there are many people who still use the mouse with laptops.
Most people back out on the option of getting a printer due to cartridge costs, however having your own printer is like no other. You could easily get coloured or black and white printout whenever you need. Just imagine a situation where you need to print a document or presentation at the last minute.

These come in all sizes and hence will not take up much space on your work-desk.
