RAM is like our short term memory. It is used as the working memory of the computer, where the computer can store and read the program instructions. This type
of memory is volatile, so once the current source is removed, every part of the memory is wiped off, you need to back up the information on RAM if you want it to be
accessible later.RAM is generally used in the primary memory of the computer to load the data and information from the hard disk. It is also used to make cache memory,
which is nothing but a fast access memory on the processor chip.
