Study Notes
Primary Memory
- There are two types of primary memory: ROM (Read-Only Memory) and RAM (Random Access Memory)
ROM vs RAM
- ROM is non-volatile, meaning its contents are retained even when the power is turned off
- RAM is volatile, meaning its contents are lost when the power is turned off
- Data cannot be written to ROM, it is pre-programmed and unchangeable
- Data can be written, read, and erased from RAM
Primary Memory Function
- Primary memory provides fast access to data and instructions because it is a part of the central processing unit (CPU) and is directly connected to it
Primary Memory Size
- The size of primary memory in a modern personal computer varies, but it is typically in the range of 4-16 GB or more
