1.2 Memory
- Cache: A special type of
computer memory that can
be accessed much faster
then RAM
- Solid State/
Flash
storage:
Uses
transistors
Solid state
refers to
no moving
parts
- Virtual memory: It stores
information from Ram that is not
needed urgently
- Ram: It is a type of memory that you can change and read what
information is stored. Applications and programms use this
memory for your settings etc. The information is stored.
Applications and programs use this memory for your settings
etc. The information is temporary and when power is lost so is
the information
- RAM is a volatile storage.
RAM makes our computer
faster when booting up your
computer.
- Volatile means
that the
information can
change quickly
and upredictdly
for the worse.

Only Memory it implies that
programmer or user of the
monitor can not change the
instructions given/stored in the

- Dynamic means
the memory is
refreshed
constantly.
- Static means
that it will
stay the same
until the
power turned
