puter is a device or machine for processing information from data according to a program â a compiled list of instructions. The information to be processed may represent numbers, text, pictures, or sound, amongst many other types.Computers are extremely versatile. In fact, they are universal information processing machines. According to the Church-Turing thesis, a computer with a certain minimum threshold capability (in technical terms, one way to describe this is that the machine must have the ability to emulate a universal Turing machine) is in principle capable of performing the tasks of any other computer, from those of a personal digital assistant to a supercomputer. Therefore, the same computer designs have been adapted for tasks from processing company payrolls to controlling industrial robots. Modern electronic computers also have enormous speed and capacity for information processing compared to earlier designs, and they have become exponentially more powerful over the years. This process was dubbed Moore's Law.
