What is the purpose of memory address?

A memory address is a unique identifier used by a device or CPU for data tracking. This binary address is defined by an ordered and finite sequence allowing the CPU to track the location of each memory byte.

A memory address is an exact assigned location in RAM used to track where information is stored. On a single computer memory IC, there can be 1 million, 2 million, or more memory addresses that can be accessed at randomly, which is why memory is called RAM (random access memory).
