2. CACHE MEMORY
It is an electronic memory specific to the processor and

is usually located near the central processing unit (CPU), or
on the CPU chip itself. It is similar to RAM, but smaller and
much faster than it. The processor uses it to store some
special data that it needs repeatedly, for easy reference. Very
quickly and to reduce the average time required to reach the
target.

Cache memory is called (cache), from the French verb (cacher), which means
hidden. The reason is that access to this memory is not always open to
applications and programs. Rather, the processor places the information itself in
the cache memory.

3. Read-only memory )ROM(
It is an electronic memory and contains information placed by the manufacturer
of the device (or motherboard). This information is useful in the initial operation
of the device and performing some other necessary
functions.

It is called read-only memory, and it is a type of
memory that can only be read from, in order to
preserve the program stored on it by the
manufacturer, in order to protect it from being
written to so that it is not damaged.

It is the BIOS program, which is an abbreviation for the term Basic Input
Output System, which means the system. Or the basic program for entering and
exiting information, and this program is responsible for the basics of the
computer’s operation, and it contains all the programming commands that the
computer needs during the operation and booting process, and the information
that is found on this memory is permanent and non-volatile information, even
when the power is disconnected from it.
