Just like we use a port to transport any goods, similarly we need a port to send or receive the data in a computer. These are called System Ports.
A Port is an interface through which data is sent or received. We connect the devices to the ports. Modern computers have ports, which are colored and marked specifically to indicate which device fits into a particular port. You cannot fit a device into a wrong port as the device will not fit in and all the ports are marked universally the same.
- The first port is for the input devices or PS/2 connectors, which is a female connector. The keyboard connector is always in blue and the mouse connector is in green.
- The two small rectangular hollow boxes are USB (Universal Serial Bus) connectors. You can plug in high speed serial devices into this port.
- The small square type connector is called Ethernet port, which is used to connect network cable. The connector looks like a telephone connector.
- The 9 pin blue male connector is for connecting the modem.
- The blue 15 pin female connector is for connecting the monitor.
- The purple color female connector is a parallel port for connecting a printer.
- The yellow color female connector is a game port and is used to connect the joystick.
- The last three sockets are for connecting speakers, headphones and microphones.
