In this article, we will see or learn all about the basics of computers or basic information technology (BIT).
Computer Organization: Input output ports
Input-output ports: Input-output ports are the port or area in a system from where a system can communicate with exterior elements or other systems.
Input output ports are:
Serial port:
Serial port also called as RS 232 represent the first interface to allow the computer to exchange information with the outside world
Serial ports are originally able to only send data and not received. hence two-way ports were developed
Parallel port:
Parallel data transmission involves sending data simultaneously on several channels.

USB:
- Universal serial bus port.
- USBs are used to transfer data from one computer to another.
- The main reason behind USB ports are
- USB are cheaper than parallel cables
