Universal Serial Bus ports

          Universal Serial Bus ports:

                                                       USB is the most common types of port to connect devices to a computer. It is used to connect different devices such as keyboard , mouse , digital camera, scanner and printer, and USB flash drive etc. It can connect up to 127 different peripheral devices. USB  ports can be used as a power supply for different devices like smartphone and tablets etc. Most laptop and desktop computers normally come with at least two ports. 

     USB ports support hot swapping and plug-and-play (PnP). Hot swapping is the ability to connect and disconnect devices shutting down the computer. Plug-and-play enables a  computer to automatically detect and configure a device when it is connected to the computer. 

      Multiple devices can be attached to USB port through daisy chain. It means that the first device the first is attached to the USB port of the computer, second USB device connect to the first USB device, the third USB device connect to the second USB device and so on.

        An alternate to daisy chain is USB hub. USB hub plugs into the USB port on the system unit. It contains multiple USB ports used to connected many USB devices. Some USB hubs   are wireless. The receiver is connected to a USB port on computer and USB hub communicates wireless with the receiver.

      Several USB versions have been released USB 1.0 and 1.1 were released between 1996 and 1998 with a speed range from 1.5 Mbps up to 12 Mbps. Gbps and charges devices faster than previous USB ports. USB 3.0 is backward compatible. It means that it supports the older devices as well.

Thunderbolt Port:

                                     Thunderbolt is an interconnect technology developed by Intel. Thunderbolt port is the fastest type of port used to connect devices to a computer. It supports a transfer speed of up to 10Gbps. It is very useful for laptop and Ultrabook's due to slim design. It can connect up to six different peripheral devices. It can also be used to connect USB and five Wire peripherals using proper adapter. Apple was the first company that used this port on its computer. 

HDMI Port:

                         HDMI stands for  high-definition multimedia interface. HDMI port is digital port that can transmit both audio and video signals. It is the standard connection for high-definition TVs, video game consoles and other media devices. All currently available monitors, DVD players, television and game consoles have at least one HDMI port. It is the most common multimedia port.

Fire Wire Port:

                                 Fire Wire is also known as IEEE 1394. It was originally released by Apple in  1995. It supports hot swapping and can connect up to 63 devices per port. It can be used to transfer data between two or more digital devices such as camcorders  and digital cameras etc. 

     A Fire Wire hub is a device that plug into a Fire Wire port on a system unit. It contains multiple Fire Wire ports to plug cables to Fire Wire devices. It can be used to attach multiple devices to a single Fire Wire port.
