For example, port 80 is the http network port. A listing of commonly known and used ports can also be found on the below listing. Techopedia Explains Computer Port.
What Does Computer Port Mean? Techopedia Explains Computer Port Computer ports have numerous functions and connectors of varying designs. Types of computer ports include: Serial Ports: These are most commonly used for connections to mice and modems.
Parallel Ports:These are most commonly used for printers. Small Computer System Interface SCSI Ports: These are used to connect printers and up to seven total devices, such as hard disks and tape drives, to the same port; they can support higher data transmission speeds than serial or parallel ports. Universal Serial Bus USB Ports: As the name implies, these can be used to connect many devices including all previously mentioned plus keyboards, scanners, external hard drives, USB drives also sometimes called thumb drives or portable USB drives , cameras, iphones and many other peripherals and devices.

Even though Mini DisplayPort has 20 pins, the physical size of the connector is smaller than a regular DisplayPort and the pin out is also different.
RCA Connector can carry composite video and stereo audio signals over three cables. Composite video transmits analogue video signals and the connector is as yellow colored RCA connector. The video signals are transmitted over a single channel along with the line and frame synchronization pulses at a maximum resolution of i standard resolution.
The red and white connectors are used for stereo audio signals red for right channel and white for left channel. Component Video is an interface where the video signals are split into more than two channels and the quality of the video signal is better that Composite video.
Like composite video, component video transmits only video signals and two separate connectors must be used for stereo audio. Component video port can transmit both analogue and digital video signals. The ports of the commonly found Component video uses 3 connectors and are color coded as Green, Blue and Red.
S-Video or Separate Video connector is used for transmitting only video signals. The picture quality is better than that of Composite video but has a lesser resolution than Component video. The S-Video port is generally black in color and is present on all TVs and most computers. Out of the 4 pins, one pin is used to carry the intensity signals black and white and other pin is used to carry color signals.
Both these pins have their respective ground pins. The pinout diagram of an S-Video port is shown below. HDMI can be used to carry uncompressed video and compressed or uncompressed audio signals. HDMI 2. The pinout diagram of an HDMI port is as follows. While HDMI 2. Coming to the display resolution, HDMI 2. With HDMI 1. USB port can be used to transfer data, act as an interface for peripherals and even act as power supply for devices connected to it.
