Different Types of Computer Connectors

 The USB Port

The Universal Serial Bus (USB) is used to connect peripherals devices like, keyboard, mouse, printer, USB drive, external hard drive, digital camera, mobile phones etc. This cable is used to transfer data between connected devices and in some cases provides power.

* USB 1.0 and 1.1 the first commercial versions supported a maximum data rate of 12 Mbps.
* USB 2.0 supported maximum data rate of 480 Mbps.
* USB 3.0 supported maximum data rate of 4.8 Gbps.

The FireWire Interface

FireWire is used to connect power devices that require a lot of bandwidth. For example in the case of some digital cameras, external hard drives and printers. There are currently two versions of FireWire cables: FireWire 400 and FireWire 800. The FireWire 800 is twice faster than the FireWire 400. The FireWire 400 is also called IEEE-1394a and FireWire 800 is also called IEEE-1394b. FireWire 400 has two types of connector’s 6-pin connector and 4-pin connector. 6-pin connector is used for computers and 4-pin connector is used for output ports on many tape-based digital video and HD camcorders.
* FireWire 400 – Speed up to 400Mbps (Megabits per second).
* FireWire 800 – Speed up to 800Mbps (Megabits per second).

DB9 and DB25 Connectors

These are old ports respectively called "serial" and "parallel port" for the connection of older generation devices like: older printers. DB9 and DB25 connectors are increasingly often replaced on computers and devices by USB and network. DB9 has the smallest "footprint" of the D-Subminiature connectors, and 9 pins houses for the male connector and 9 holes for the female connector. The DB25 connector is an analog 25-pin plug of the D-Subminiature connector.

The Audio Jacks

 The Audio jacks are used to transmit sound. They are used to connect your computer to the speakers (output, "line out"), a stereo (input, "line in") and / or a microphone.





The Ethernet Port

It is a rectangular plug that receives a cable called RJ45. It is used to connect a computer to a network, a router or ADSL box. It allows you to connect to the Internet or an intranet. Among the available Ethernet cables, there are several variations, more or less rapid: Ethernet, Fast Ethernet and Gigabit Ethernet.



The VGA Connector

VGA Connector is also called RGB, HD-15 or SUB-D15, it allows you to connect analog graphics card of a computer screen. It is usually blue. This port is progressively more replaced on computers, computer monitors and TVs with HDMI or DVI, faster and capable of supporting a much wider range of color ports.



The HDMI Connector

 HDMI "High Definition Multimedia Interface", nicknamed "HD SCART socket" is used to transmit multimedia data like audio and video in high definition. It should soon provide all the audio and video equipment.




  The DVI Connector

DVI "Digital Visual Interface" allows you to connect your computer to a screen, such as flat-panel LCD monitor and deliver the highest quality video signals. DVI is a video display interface developed by the industry Digital Display Working Group (DDWG).
