4. Cabinate
A computer case, also known as a computer
chassis, tower, system unit, or cabinet, is the
enclosure that contains most of the components of
a personal computer. Cases are usually constructed
from steel, aluminium and plastic.
5. SMPS (Switch mode and power supply)
SMPS stands for Switched-Mode Power Supply. It
is an electronic power supply that uses a switching
regulator to convert electrical power efficiently. It is
also known as Switching Mode Power Supply. It is
power supply unit (PSU) generally used in
computers to convert the voltage into
the computer acceptable range.
6. MOTHERBOARD
A motherboard (also called mainboard, main
circuit board, system board, baseboard, planar
board, logic board, or mobo) is the main printed
circuit board (PCB) in general-purpose
computers and other expandable systems.
7. HARD DISK
A hard drive is the hardware component that
stores all of your digital content.Your
documents, pictures, music, videos, programs,
application preferences, and operating system
represent digital content stored on
a hard drive. Hard drives can be external or
internal.
8. D.V.D Reader
In computing, an optical disc drive is a disc drive
that uses laser light or electromagnetic waves
within or near the visible light spectrum as part
of the process of reading or writing data to or
from optical discs.
9. Processor
A processor (CPU) is the logic circuitry that
responds to and processes the basic instructions
that drive a computer. ... CPUs will perform most
basic arithmetic, logic and I/O operations, as well
as allocate commands for other chips and
components running in a computer.
