The processor finds programs and data from memory when it does its assigned task. The memory is the place where every thing is kept. The microcomputers memory is just a temporary space like a chalkboard where the computer scribbles while work is being done. Unlike human memories, the computer's memory is not a permanent repository. The computer's memory simply provides a place where computing can happen.
The processor makes vital distinction between programs and data. It is the same with the microcomputers memory. Only processor recognizes the difference between program and data.
Anything can be written on the memory, and the writing can be changed by writing over it. Unlike a chalkboard, the computer's memory doesn't have to be erases before something new can be written to it; the act of writing automatically erases what was in the memory before. Reading information from the memory is simple and straightforward as reading any thing written on paper. Both the processor and the I/O devises have the capability to read and write data from and to the main memory.
