Ports are nothing but it is connections between external and internal input/output devices such as keyboards, mice, mouse, Disk Drive, and many more with motherboards using cables. That allows to communicate between external devices or peripherals with a laptop or computer. Computer ports may be virtual or physical. In this article, we are going to discuss about different types of physical computer ports available in the market.
There are different characteristics of computer ports:
There are two types of computer ports discussed below:
Let us now discuss a few important types of ports:
Now let us discuss these ports one by one:
A serial port is also called a communication port and they are used for connection of external devices like a modem, mouse, or keyboard (basically in older PCs). Serial cables are cheaper to make in comparison to parallel cables and they are easier to shield from interference. There are two versions of the serial port, which are the 9-pin serial port model and the 25-pin serial port model. The rate of transmission of data in the serial port is 115 KB/sec.
Parallel ports are generally used for connecting scanners and printers. It can send several bits at the same time as it uses parallel communication. Its data transfer speed is much higher in comparison with the serial port. It is a 25-pin model. It is also known as Printer Port or Line Printer Port.
In 1997 USB was first introduced. This can connect all kinds of external USB devices, like external hard disk, printer, scanner, mouse, keyboard, etc. There are a minimum of two USB Ports provided in most of the computer systems. It is a kind of new type serial connection Port that is much faster than the old serial Ports These USB Ports are much smarter and more versatile, as they allow the “daisy chaining” of up to 127 USB peripherals connected to one port. The data transfer rate in this is Data12 megabits per second. It also provides plug-and-play communication.
PS/2 ports are special ports used for connecting old computer keyboard and mouse. It was invented by IBM. In old computers, there are a minimum of two PS/2 Ports, each for the keyboard and the mouse. It is a 6-pin mini Din connector.
VGA ports also known as Video Graphic Array connectors are those which connect the monitor to a computer’s video card. VGA port has 15 holes and it is similar to the serial port connector. But VGA Ports have holes in it and the serial port connector has pins in it.
Microphones and speakers are connected with the help of Sockets to the sound card of the computer.
The IEEE 1394 interface, which is developed in the late 1980s and early 1990s by Apple as FireWire. It can transfer large amounts of data at very high speed. It is used to connect camcorders and video equipment to the computer. It comes up with three variants which are 4-Pin FireWire 400 connector, 6-Pin FireWire 400 connector, and 9-Pin FireWire 800 connector.
An infrared port is a wireless communication interface that is used to send and receive infrared signals from other devices. The range of connectivity of the infrared port is 5-10ft. Infrared port allows devices to communicate without a physical connection.
These ports are used previously to connect a joystick to a PC. But nowadays it is replaced by USB ports.
As the name suggests, a Modem port is used to connect a PC’s modem to the telephone network.
DVI Port is used to connect an LCD(flat panel) monitor to the computer’s high-end video graphic cards and it is very popular among video card manufacturers.
Ethernet Port helps to connect to a network and high-speed Internet(provided by LAN or other sources). It connects the network cable to a computer and resides in an Ethernet card. It provides a data travel speed of 10 Mb to 1000 Mb(megabits) per second.
The full form of USB is Universal Serial Bus.
Ethernet cable is used for networking and internet, because ethernet port helps to connect to a network and high speed Internet(provided by LAN or other source).
Microphone and speakers are connected with the help of Sockets to the sound card of the computer.

PS/2 ports are special ports used for connecting old computer keyboard and mouse. In old computers there are minimum two PS/2 Ports, each for the keyboard and the mouse.
There are two versions of Serial ports, which are 9 pin model and 25 pin model. It transmits data at 115 KB/sec.
