RAM stands for Random access Memory. The main function of RAM is to act as a temporary store of data and program instructions so that they can be retrieved quickly by the CPU when they are required.
If they were stored on the hard disk drive, it would take longer to retrieve them when they were required and so slow down the processing speed of the CPU.
RAM (Random Access Memory) is storage used for a place to hold data. Think of it as a big filing cabinet that keeps things ready for the CPU in your phone to present it to your eyes and ears.
