2. Processors CPU is a short name for
Central Processing Unit,
(CPU) it’s a brain of the
computer. The CPU will
likely be the larger of
the chips on the
mainboard inside your PC
The are only CPU
measured in 64-bit and
32-bit.
There are many
different types of CPU

how much speed that
your laptop or desktop
need.

your laptop or desktop
motherboard.
3. ROM stand for Read-Only
Memory memory, is a class of storage
medium used in computers
and other electronic devices.
Data stored in ROM cannot
be modified, or can be
modified only slowly or with
difficult, so it is mainly used
to distribute firmware.
RAM stand for Random
Access Memory, RAM is a
form of computer data
storage, it takes the form
of integrated circuits that
allow stored data to be
accessed in any order with a
worst case performance of
constant time.
4. Memory EPROM stand for
erasable programmable
(part 2) read only memory, is a
type of memory chip that
retains its data when its
power supply is switched
off.
Flash memory is a non-
volatile computer storage
chip that can be
electrically erased and
reprogrammed. It was
developed from EEPROM
and must be erased in
fairly large blocks before
these can be rewritten
with new data.
5. Video card is an expansion card
which generates output images
to a display, video hardware is
Adapter Card often integrated into the
motherboard, however all
modern motherboards provide
expansion ports to which a
video card can be attached.
Sound card is an internal
computer expansion card that
facilitates the input and output
of audio signals to and from a
computer under control of
computer programs.
Network card is a computer
hardware component that
connects a computer to a
computer network. Whereas
network interface controllers
were commonly implemented
on expansion cards that plug
into a computer bus.
6. SATA stand for Serial
Advanced Technology
Storage Devices Attachment) is a
computer bus interface
for connecting host bus
adapters to mass storage
devices such as hard disk
drives and optical drives.
PATA stand for Parallel
ATA , originally AT
Attachment, is an
interface standard for
the connection of
storage devices such as
hard disks, solid-state
drives, floppy drives, and
optical disc drives in
computers.
7. SCSI stand for Small Computer
System Interface and it a set of
Storage Devices standards for physically
connecting and transferring data
(part 2) between computers and
peripheral devices. The SCSI
standards define commands,
protocols, and electrical and
optical interfaces.
Solid state is a data storage
device that uses solid-state
memory to store persistent data
with the intention of providing
access in the same manner of a
traditional block i/o hard disk
drive. SSDs are distinguished
from traditional magnetic disks
such as hard disk drives (HDDs)
or floppy disk, which are
electromechanical devices
containing spinning disks and
movable read/write heads.
