Memory (Primary Storage Device)
Memory contents, locations, and addresses (read text).



Memory stores programs and data on their way to be processed by the CPU. What stored in memory can be categorized as:

- Input data supplied by input devices as keyboards.

- Output data to be sent to output devices as monitors.

- Intermediate data resulted from processing input data.

- Programs.

Memory is partitioned into many memory locations, with each location having a unique address and a location's size is fixed. Suppose n bits are used to form the memory address. Since each bit can be set to 0 or 1, the maximum possible number of memory locations is 2n. If the location size is 1 byte. Then, maximum memory size = 1x 2n byte.
