The document provides descriptions of common computer hardware components. It describes the central processing unit (CPU) as carrying out program instructions. The motherboard holds crucial components and connects peripherals. Hard drives store files using rigid rotating discs in various form factors. A network interface controller (NIC) allows computers to communicate over a network. Fans cool components to prevent overheating. Optical drives read discs like DVDs. Random access memory (RAM) temporarily stores data for fast access. A sound card facilitates audio input and output. USB connectors define cables and communication standards. Adapter cards expand functionality via slots. Common input devices include touchscreens, graphics tablets, and keyboards. Output devices include printers, monitors, and speakers.

2. CPU (Central Processing
Unit)
 The central processing unit (CPU) is the
source that carries out the instructions of
a computer program. It basically gives
instructions to the computer.

3. Motherboard
 A motherboard is the central printed circuit
board in many modern computers and holds
many crucial components of the system
providing connectors for other peripherals.

4. Hard Drive
 A hard drive is used for comprising one
or more rigid rotating discs. You can
save your files, music, documents and
download certain things. There are
different types of hard drive external,
internal.

5. NIC card
A network interface controller (NIC) is a
computer hardware component that
connects a computer to a computer network.
This NIC allows computers to communicate
over a computer network.

6. Fans
The fans are used to cool down the
components in the computer, so they don’t
overheat and break. It also draws cold air in,
to give a better circulation.

7. Optical drive
In computing an optical drive is a disk drive
that uses laser light or electromagnetic
waves near the light spectrum. You can play
DVDs and other discs in a optical drive.

8. RAM
Random access memory (RAM) is a form of
computer data storage. Today it takes the
form of integrated circuits that allows stored
data to be accessed in any order with a worst
case of performance of constant time.

9. Sound card
A 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.

10. USB connector
Universal serial bus (USB) is an
industry standard developed in the
mid 1990s that defines the cables,
connectors and communication
protocols used in a bus for connection.
And also communication and power
supply between and electronic
devices.

11. Adapter cards
 A adapter card in computing is a printed
circuit board that can be inserted into an
expansion slot of a computer
motherboard. Types of adapter cards
PCI, PCIe and card bus.

12. Input Devices
 There are many input devices that
involve in our everyday life. There is
thing like touch screen , graphics , tablet
, games controller , microphone and
keyboard . Out of the examples touch
screen is the most used, as it used for
smartphones as these type of phones
have become highly popular.

13. Output Devices
 Printer , monitor and speakers are all
types of outputs. Printers used widely in
businesses and in home use. Monitors
are also the same as they are widely
used in businesses and in home use.
Speakers are mostly used in the music
industry. The speakers output sound ,
the printer outputs images and the
monitor outputs light.
