A computer is a machine that makes it possible to work with information (numbers, words, images, sounds) called data.
Computers can process large quantities of data, store them and display them.
The first computer was invented in the 1830s by a British inventor, Charles Babbage.
In 1971 appeared the first microcomputer.

Programs and data are permanently stored on storage. Most computers are equipped with a hard disk that stores data on a metal disc, into the computer. In some storage devices (CDs, DVDs), the data are placed on disks that can be switched from one machine to another.
These media facilitate data sharing.
