What two tasks can be performed by RAM?

Answer 1

One task that can be performed by RAM (random-access memory) is to store data that is input into an application and holds it there only while the application is running. RAM also allows a user to do more things at once, depending on the amount of RAM the computer has. In other words, the more RAM your computer has, the more windows you can have open to work in without slowing down your computer.

Answer 2

The two functions of RAM is to process and store data, where as the two functions of ROM is to read and write.

RAM does no processing of data, the CPU does that. ROM cannot be written, it is read only by definition.

Both RAM and ROM reside in the memory space of the CPU, where it can read both RAM and ROM but can only write RAM.

ROM typically stores instructions and data that must not change for the computer to operate properly (e.g. boot, BIOS, system initialization data).

RAM typically stores instructions and data what change in normal operation of the computer (e.g. OS, Plug & Play I/O drivers, user applications).
