1.6 Memory

Memory is accessed faster than secondary storage.

Memory is used to store instructions so that the processor can quickly fetch, decode and execute them.

There are three types of memory:

• RAM (Read Only Memory)
• ROM (Random Access Memory)
• Flash Memory

RAM (Random Access Memory)

This is how you should understand the difference between secondary storage, RAM, and the processor.

RAM stores instructions and programs currently in use.

RAM is volatile – meaning that when power is lost, all the data stored on it is also lost.

The size of the RAM impacts user experience.
