RAM is a fast temporary type of memory in which programs, applications and data are stored. Here are some examples of
what's stored in Ram:
The operating system
applications
the graphical user interface (GUI)
If a computer loses power, all data stored in its RAM is lost
ROM stands for Read-Only Memory
Non-Volatile
ROM is memory that cannot be changed by a program or user. ROM retains its memory even after the computer is turned off. For example, ROM stores the instructions for
the computer to start up when it is turned on again.
