COMPUTER HARDWARE
Computer hardware includes
the physical parts of a
computer, such as the case,[1]
central processing unit (CPU),
random access memory (RAM),
monitor, mouse, keyboard,
computer data storage,
graphics card, sound card,
speakers and motherboard.[2]
MOTHERBOARD
A motherboard is the main
printed circuit board in general-
purpose computers and other
expandable systems. It holds and
allows communication between
many of the crucial electronic
components of a system, such as
the central processing unit and
memory, and provides connectors
for other peripherals
CPU ( CENTRAL PROCESSING UNIT)
A central processing unit, also
called a central processor,
main processor or just
processor, is the electronic
circuitry that executes
instructions comprising a
computer program. The CPU
performs basic arithmetic,
logic, controlling, and
input/output operations
specified by the instructions in
HOW CPU WORKS ?
COMPUTER COOLING FAN
Computer cooling is required to
remove the waste heat produced
by computer components, to keep
components within permissible
operating temperature limits.
Components that are susceptible
to temporary malfunction or
permanent failure if overheated
include integrated circuits such as
central processing units (CPUs),
chipsets, graphics cards, and hard
disk drives.
RAM
Random-access memory is
a form of computer
memory that can be read
and changed in any order,
typically used to store
working data and machine
code.
ROM
Read-only memory, or ROM, is
a type of computer storage
containing non-volatile,
permanent data that, normally,
can only be read, not written
to. ROM contains the
programming that allows a
computer to start up or
regenerate each time it is
turned on.
OPTICAL DISC DRIVE
• 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. Some drives can only
read from certain discs, but recent drives
can both read and record, also called
burners or writers (since they physically
burn the organic dye on write-once CD-R,
DVD-R and BD-R LTH discs). Compact
discs, DVDs, and Blu-ray discs are
common types of optical media which can
be read and recorded by such drives.
OPTICAL DISC DRIVE
HARD DRIVE
A hard disk drive, hard disk,
hard drive, or fixed disk is an
electro-mechanical data
storage device that stores and
retrieves digital data using
magnetic storage with one or
more rigid rapidly rotating
platters coated with magnetic
material. It is secondary
Memory Device.
SOLID-STATE DRIVE
A solid-state drive is a solid-
state storage device that uses
integrated circuit assemblies to
store data persistently,
typically using flash memory,
and functioning as secondary
storage in the hierarchy of
computer storage.
POWER SUPPLY UNIT
A power supply unit converts mains
AC to low-voltage regulated DC
power for the internal components of
a computer. Modern personal
computers universally use switched-
mode power supplies. Some power
supplies have a manual switch for
selecting input voltage, while others
automatically adapt to the mains
voltage.
NETWORK INTERFACE CONTROLLER
A network interface controller
is a computer hardware
component that connects a
computer to a computer
network. Early network
interface controllers were
commonly implemented on
expansion cards that plugged
into a computer bus.
GRAPHICS PROCESSING UNIT
A graphics processing unit is a
specialized electronic circuit
designed to manipulate and alter
memory to accelerate the creation
of images in a frame buffer
intended for output to a display
device. GPUs are used in
embedded systems, mobile
phones, personal computers,
workstations, and game consoles.
WIRELESS NETWORK INTERFACE
CONTROLLER
A wireless network interface
controller is a network
interface controller which
connects to a wireless network,
such as Wi-Fi or Bluetooth,
rather than a wired network,
such as a Token Ring or
Ethernet.
SOUND CARD
A sound card is an internal
expansion card that provides
input and output of audio
signals to and from a computer
under the control of computer
programs. The term sound
card is also applied to external
audio interfaces used for
professional audio
applications.
COMPUTER PORT
In computer hardware, a port
serves as an interface between
the computer and other
computers or peripheral
devices. In computer terms, a
port generally refers to the part
of a computing device available
for connection to peripherals
such as input and output
devices.
