Good Day Katreena,

There are many types of computer ports, please see below the details:
Serial port  – used for RS232 connectors and devices
Parallel port – used for LTP printers
PS/2 ports – used for keyboard and mouse
VGA port – used for monitors and LCD output
HDMI – used for LCD's and TV's with HDMI connector
DVI, mini-DVI and micro-DVI – used for digital video interface
                  
LAN port or Ethernet – used for network patch cord to connect to internet and network access at high speed
Modem – used to connect internet via telephone line or dial up connection
USB port – used to connect other USB devices                                                                                                                                                                       
SATA / eSATA port – used for hard drive with SATA connector
PCMIA / Cardbus – used for WIFI and explanation cards
                   
Audio jack sockets – used for microphone, stereo line-in, stereo line-out, etc.
Firewire – used to transmit data in high-bandwidth digital devices faster by USB

Hi Katreena, the computer has different types of ports, 10 ports to be exact. These are;

  • Serial port
  • Parallel port
  • USB port
  • Ethernet port
  • VGA port
  • IEEE interface port
  • PS/2 port
  • Digital visual interface
  • SCSI port (Small Computer System Interface)
  • TRS port
  1. Serial port – This is the port in the computer that connects the monitor to the system unit via a cable. The monitor cannot display the information without the cable connected via this port. The information here transfers in 1 bit at a time
  2. Parallel port – This is a port in which the printer cable is connected to the computer. The computer sends information to the printer via the port
  3. USB port – This is a general port in which flash drives or any external device e.g camera, modem can be connected to the computer for transfer of data and information.
  4. Ethernet port – This is the port where the computer connects with the internet via the network cables. e.g the shielded twisted pair and unshielded twisted pair. The data is usually transferred in megabytes per second.
  5. VGA port – This is the type of port in which the computer connects to the monitor to show the contents in the computer i.e programs, and information which is displayed on the screen.
  6. IEEE interface port – This is also known as IEEE 1394 port  and is where the computer connects to other computers via it. It is used for high speed communication and synchronous realtime data transfer mostly by personal computers. It is also known as firewire and is also used for fiber optic connections
  7. PS/2 port – This is the port in which the keyboard or mouse connects to the computer with. It transfers data quickly. The keyboard or mouse cannot communicate with the computer without the connection through the port, unless of course, those that use the USB port!
  8. Digital Visual Interface – This is a data transfer point in which the computer can connect with an external monitor like a television for display or projector screen.
  9. SCSI (Small Computer System Interface) port –  This is a port in which the computer uses to communicate with hard disks, tape drivers or even scanners and CD/dvd drives. It uses peer to peer interface methodology.
  10. TRS port – This is a connection interface in which a video device or speaker/microphone can be used to connect and transfer data with a computer mostly using a jack pin.

So those are the types of devices and their uses in the computer.

Thanks
