Ports
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.
1)
Ps2 ports-- The PS/2 port is a 6-pin mini-DIN
connector used for connecting keyboards and mouse to a PC compatible computer
system. Its name comes from the IBM Personal System/2 series of personal
computers, with which it was introduced in 1987.
2)
USB port-- Universal Serial Bus is an industry
standard that used for connecting, data transferring and powering of hosts,
such as personal computers, peripherals, e.g. keyboards and mobile devices, and
intermediate hubs.
3)
VGA Port--
The Video Graphics Array connector is a standard connector used for
computer video output. The 15-pin connector went on to connect PCs, as well as
many monitors, projectors and high-definition television sets.
4)
HDMI Port-- High-Definition Multimedia Interface is
a proprietary audio/video interface for transmitting uncompressed video data
and audio data.
5)
ATX connector-- 3 pin ATX connector is used for
connecting SMPS to power board. The three pins are for earth, live, nutral.
6)
Ethernet port-- A Ethernet port is a jack or socket on
a computer that allows the use of an Ethernet connector. These ports are
essential in allowing the creation of local area networks (LANs). An Ethernet
port is usually found on networking devices, including computers, routers,
video game consoles, modems, and televisions.
7)
Parallel port-- In summary, the parallel port was a
common interface used in the past for connecting various peripherals like
printers, scanners, and external drives to computers. However, due to its
limitations and the advent of more advanced interfaces like USB, it has become
largely obsolete in modern computing.
8)
20 Pin ATX Connector-- The 20-pin ATX connector is a
power supply connector used in older computer systems, primarily before the
industry standard shifted to the 24-pin ATX connector. The ATX (Advanced
Technology Extended) power supply connector provides power to the motherboard
and other components within a computer case. Here's some information about the
20-pin ATX connector.
9)
Audio Ports:
§ Headphone Jack (3.5mm):
This is a common audio output port that allows you to connect headphones or
external speakers to your computer. It's often color-coded green.
§ Microphone Jack
(3.5mm): This is an audio input port used for
connecting an external microphone. It's often color-coded pink.
§ Line-In Jack (3.5mm): This is an audio input port used for connecting external audio sources, such as music players or other devices, to your computer.
