A keyboard is a peripheral device modeled after the typewriter keyboard. Keyboards are designed for the input of text and characters, and also to control the operation of the computer

A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface.

A printer is used to print pages from a computer. It is a device that takes digital information from a computer and transfers it onto physical paper, creating a hard copy of documents, images, or other content. By sending a print command from the computer to the printer, the printer uses ink or toner to reproduce the digital content onto paper, allowing users to have physical copies of their digital files.
