Coming up next are some normal kinds of ports. 

(I). Sequential Ports 

(ii). Equal Ports 

(iii). PS/2Port 

(iv). USB Port 

(v). Fire Wire Port 

(i) Serial Ports: 

A sequential port is a sequential correspondence actual interface through which data moves in or out the slightest bit at a time. These ports were utilized in old kinds of PCs to associate gadgets like modems. Sequential ports have 9 or 25 pins in which one pin is utilized for communicating information and the rest are utilized to send control signals. These ports are called COM 1(Component Object Model), COM 2 and COM 3. 

These ports have been supplanted with USB ports in current PCs. 

(ii) Parallel Ports: 

An equal port is an equal correspondence actual interface. It is otherwise called a printer port. Equal ports can send different pieces throughout a few wires all at once. These ports have 25 pins in which 8 pins communicate one byte of data and the others are utilized for sending control signals. Equal ports are named as LPT 1(line Print Terminal), LPT 2 and LPT 3. In today current PCs equal ports have been supplanted with USB ports. 

(iii) PS/2Port: 

The PS/2 connectors are utilized for interfacing console and mouse to an IBM viable PC. Its name comes from the IBM individual frameworks arrangement of PCs which were presented in 1987.
