A '''computer''', like a calculator, is a machine that is designed to perform [[mathematical]] calculations.  A computer differs from a calculator in that it follows a program stored in its memory, rather than requiring the user to enter instructions one at a time.  Most computers manipulate data in the form of [[binary|binary code]], which consists of 1s and 0s.

A '''computer''', is a machine that is designed to perform multiple different tasks set depending on the program it has stored in its memory. These could be solving [[mathematical]] problem, or controlling [[Robots|robotic arms]].  Computers manipulate data in the form of [[binary|binary code]], which is base 2. This means that there can only be a 1 or a 0 in any place value.
