What is the function of RAM in a desktop computer?
Temporary data storage for running applications
RAM (Random Access Memory) is the computer’s main volatile memory, meaning it holds data only while power is supplied and loses everything when the system is switched off.
The CPU keeps the currently running programs and their working data in RAM because it can be read from and written to very quickly, far faster than a hard disk.
Permanent storage of files, folders and backups is the job of the hard disk or SSD, and actual calculation is done by the processor — not by RAM.
So RAM serves as the temporary, high-speed workspace for applications that are currently active.
Hence, the answer is temporary data storage for running applications.
