 A port is a connector at the back of a computer where you plug in an external device such as a printer, keyboard, scanner, mouse, modem, etc.  this allows instructions and data to flow between the computer and the device.  the computer ports are also commonly referred to as the Input/Output ports (I/O ports).

 Most connectors are polarized.  this permits the cable to be plugged in only in the correct direction.  Computer ports have numerous functions and connectors of varying designs.

 Serial Ports  most commonly used for connections to mice and modems.

 Parallel Ports  most commonly used for scanners and printers.  also called the “printer port”.

 P.S. the basic difference between serial and parallel ports is that of the speed. Parallel port is needed for high speed connection like printers.  P.S.S. serial and parallel ports are now replaced by USB interface.

 PS/2 Ports  small, round-shaped ports consisting of 6 pins.  both ports (for mouse and keyboard), look the same. The only difference comes in their color. The purple one is for keyboard and green is for mouse.  P.S. nowadays we have USB ports for mouse and keyboard.

 VGA Port  used for connecting a computer to a monitor, or the CPU to the computer monitor.

 HDMI (High Definition Multimedia Interface)  ports on computer to transmit High Definition (1080p+) Video from the computer video card to the monitor/TV.

 Ethernet/Internet Ports  first introduced in 1980 to standardize the local area networks (LAN).  used to connect to internet and intranet networks at high speed.

 Universal Serial Bus (USB) Ports  used to connect many external devices including keyboards, scanners, external hard drives, USB/flash drives (also sometimes called thumb drives or portable USB drives), cameras, iPhones and many other peripherals and devices.

 E-SATA  found on the latest computers. These let you plug in the newest breed of portable hard drives with extra speed and larger capacity.  One reason why people prefer e-Sata over USB is that the transfer rate is really fast.
