What is memory?
Memory is any physical device capable of storing information temporarily, like RAM (random access memory), or permanently, like ROM (read-only memory). Memory devices utilize integrated circuits and are used by operating systems, software, and hardware.
- MEMORY CAN BE VOLATILE OR NON-VOLATILE
Volatile memory – This is the memory that losses it content when the computer power off. RAM is the example of volatile memory.
Non-volatile memory – This is the memory where data can be automatically save in system if electricity off. ROM is the example of non-volatile memory.
- How memory is used?
When a program such internal browser is open. It is loaded from your hard drive and placed into the ram which allow the program with communicate with the processor.
