The Input/Output (I/O) ports are used to connect various devices to the computer and hence enable communication between the device and the computer.
These ports are typically present at the backside of the computer.
They are clearly marked.
Example: External Modem is connected to serial ports; Printers are connected to parallel ports.These ports help in transmitting the data from the device to the computer and vice versa.
Each port has a specific way of communicating and this depends upon the speed and size of the port. Example: Serial, Parallel and USB.
In the following lesson, you will learn to identify these ports and list their functionality.
