RAM – Random Access Memory (temporary)
It holds the data that is being manipulated by the
CPU until it is moved to a permanent memory store
such as a disk.
RAM – Random Access Memory (temporary)
the computer can read its contents but cannot write
to the contents of memory.
ROM – Read Only Memory (Permanent)
holds permanent information such as the software
that enables the components in your computer to
communicate with each other. It cannot usually be
deleted or overwritten.
ROM – Read Only Memory (Permanent)
