Mother Board - The
motherboard or main board is the main circuit board in a computer. It
is the most 'central' part of a computer. All of the different parts
of the computer are connected to the motherboard. This lets them
work together. In most computers, the motherboard is a big green
board.
Hard Disk - Hard Disk is
used by computers to store information. Hard disks use magnetic
recording to store information on rotating circular platters. The
capacity of a hard drive is usually measured in gigabytes (GB),
however hard disc capacity can also be measured in terabytes when
the capacity is over 1000 gigabytes.
Processor Chip –
Processor Chip reads data from memory and write data to memory.
Processors today can do more than 1 billion (1,000,000,000)
instructions in a single second. The speed that a processor works at
is measured in hertz (Hz). Modern processors often run so fast that
gigahertz (GHz) is used instead, which means a billion cycles per
second.
Random Access Memory (RAM)
- Random access memory or simply RAM is the memory or information
storage in a computer that is used to store running programs and
data for the programs. Data in the RAM can be read and written
quickly in any order. Normally, the random access memory is in the
form of computer chips.
Cabinet – Cabinet is a
plastic or metal enclosure that houses most of the components. Those
found on desktop computers are usually small enough to fit under a
desk. Cabinet cases usually include sheet metal enclosures for a
power supply unit and drive bays, as well as a rear panel that can
accommodate peripheral connectors protruding from the motherboard
and expansion slots. Most cases also have a power button or switch,
a reset button and LEDs to indicate power status as well as hard
drive and network activity.
CPU Cooler – CPU Cooler
are used to cool the CPU heat sink. CPU cooler fan are attached to, a
computer case used for active cooling and may refer to fans that
draw cooler air into the case from the outside, expel warm air from
inside or move air across a heat sink to cool a particular
component.
Power Supply Unit - The
desktop computer power supply changes alternating current from a
wall socket to low-voltage direct current to operate the processor
and peripheral devices. Most modern desktop personal computer power
supplies conform to the ATX specification, which includes form
factor and voltage tolerances.
Sound Card – A sound card
is the part of the computer hardware that controls the input and
output of the sound signals. A sound card is what is known as an
expansion card. This means that the card can be added to the
motherboard. Nowadays, most of the audio cards are integrated with
the motherboard.
Graphic Card - Graphic Card
is a special circuit board that controls what is shown on a computer
monitor and calculates 3D images and graphics. A graphic card can be
used to display a two-dimensional (2D) image like a Windows desktop,
or a three-dimensional (3D) image like a computer game.
Personal Computer – A
personal computer is also called desktop. A personal computer is
designed for regular use at a single location on or near a desk or
table due to its size and power requirements. It consists of input
and output device along with other computer accessories. Demand for
personal computers declined with the introduction of laptops.
