![]() ![]() The memory is equivalent to thousands of registers, each storing a binary word." Figure 1. ![]() The memory is therefore one of the most active parts of a computer, storing not only the program and data but processed data as well. During a computer run, the control section may store partial answers in the memory, similar to the way we use paper to record our work. " The memory of a computer is where the program and data are stored before the calculations begin. To answer these questions lets first define, in modern terms, what we mean by a store, or the memory of a computational machine: Of course, in the 21st century we'd recognise this as 'computer memory', but in the 19th century this really was a groundbreaking idea.īut how does one go about mechanising memory? How does a thing remember other things? How did Babbage's ideas turn into reality? ![]() The latter - a store - would retain the numbers and instructions required to define the successive stages in computation. Charles Babbage, the famous 19th century English mathematician and polymath, once said that for a machine to perform the functions of a human computer it must possess three things: a unit capable of performing the operations of arithmetic, a built-in power of judgement and a store. ![]()
