Which of the following internal components is used for temporary data storage in a workstation?

A power supply provides electrical power to all the components of a computer, it does not store data.

The CPU (Central Processing Unit) is the "brain" of the computer, responsible for executing instructions and processing data, but it does not primarily store data temporarily in large quantities.

RAM (Random Access Memory) is a volatile form of memory used for temporary data storage where the CPU can quickly read and write data. It holds the operating system, applications, and data currently in use, allowing for rapid access and processing.

A hard drive is a form of non-volatile storage used for long-term data retention, meaning data persists even when the computer is turned off.
