Processing Devices
Processing Devices are the computer’s circuitry in the system unit.

Motherboard is
the circuit board
housing the
memory and the
central processing
unit (CPU).

Central Processing Unit
(CPU) – manipulates input data
into the information needed by
the users.

Memory – also known as Random
Access Memory or RAM. It is a
series of electronic elements that act
as temporary storage of data and
program instructions while the
instructions are being processed by
the CPU.

Chips – these make up the CPU and the
memory; these are electronic devices that
contain many microscopic pathways designed to

carry electrical currents.

Storage Devices
Storage devices store data and programs. These holds data, information and
programs permanently.

Solid State Drive (SSD) – mass storage device that stores
data in a permanent state even without power. Similar to an
HDD’s function, only the internal components are different.
SSDs do not have moving parts but store data on magnetic
platters making use of flash memory.
