Computer memory is one of the most important parts of a computer. It includes RAM (Random Access Memory), ROM (Read Only Memory), and Cache (click computer booting to know the relationship between RAM and ROM). It enables CPU (Central Processing Unit) to access instructions and data quickly.

relationship between CPU, hard drive, and memory

The memory is used to temporarily store the operational data of CPU and the data exchanged with an external memory (such as a hard disk). To put it plainly, CPU will transfer the data that needs to be operated into the memory for operation when the computer is running and transmit the result out when the operation is completed.
