Well, if a computer has a brain (CPU) , it must also have the faculty which we call memory. Indeed, it does posses a memory, however the memory of a computer is most unlike human memory. A human being can remember stored information for a long whereas a computer can not. It's memory is temporary (volatile) , it cannot remember anything after it is switched off.
The memory of a computer is more like a predefined working place, where it temporarily keeps information and data to facilitate its performance. When the task is performed, it clear it's memory and memory space is then available for the next task to be performed. When the power is switched off, everything stored in the memory get erased and cannot be recalled.
Memory Cell:- The memory of a computer can be thought of as cells. Each of these cells is further broken down into smaller parts known as bits. A bit means a binary digit I. e, 0 or 1 . A number of bits together are used to store data instructions by their combination.
A bit is an elementary unit of the memory. Eight bits together form a byte.
One byte is the smallest unit which can represent a data item or a character. Other units of memory are KB, MB, GB, TB.
