III. COMMUNICATION PORTS

Components used to communicate with other external devices such as Input/Output devices, external fax
Modems (Device used to convert PC into a fax machine, and internet surfing), Removable Storage Devices etc. There are
primarily two kinds of ports, COM ports, and USB ports.
1. COM Ports as the name suggests stands for Communication port. Present on a motherboard, these are generally
two in number, one is connected to a nine pin port (Used by Mouse), and the other to a 25 pin port (Used by printers).
The data transfer speed in these is slow as compared to other ports.
2. Serial Ports are also available on the motherboard, used primarily to connect Mouse Keyboard. These are faster
than the com ports
3. USB Port, stands for Universal Serial Bus, which is the new Industry Standard for connection of high speed
devices to the computer, these include mouse, keyboard, camera, removable storage devices, and many other
accessories.

4. Fierwire 1394 port : Fierwire 1394 port is a new global standard for transmitting extensive data to the computer
such as data from camcorder.
AS SEEN FROM THE COMPARISON, IT IS CLEAR THAT THE USB PORT IS THE CLEAR WINNER
AMONGST ALL, THANKS TO THE CONTINUOUS NEED FOR INNOVATION AND ACHIEVEMENT IN THE TECHNOLOGY.
