A computer is an electronic device that manipulates information or data. It has the ability to store, retrieve, and process data.
One can use the computer to type a document, send an email, edit photos and videos, etc. The computer is a very helpful device. It is
sought by many people. The humble beginnings and the development of the computer will be shown by this chart.
