Twisted - Pair Connectors / Internet and Networking

Twisted - Pair Connectors :-
We have discussed two major twisted -Pair connectors,  the RJ-11 for four - wire telephone cable and the RJ-45 for eight - wire network cable.  There are also barrel connectors,  which are female connectors on both ends that allow you to join two cable lengths together and reach greater distance,  not exceeding 100 meters.  RJ-45 barrel connector connecting two cable lengths together.
There are also BNC barrel connectors.

Other Connectors 
There are a number of additional connector types that you will come across in networking environments, some of which are listed here:
F-type connector :- Another connector style for coax cabling,  it is the same connector style that runs to your TV.
Fiber local connector (LC)  and mechanical - transfer registered Jack (MT-RJ)  :- Additional fiber - optic connector types that are similar to the registered Jack and SC shape.  The fiber LC is the optic connector of the two for communication exceeding 1 Gbps due to its small from factor.
Universal serial bus (USB) :- A  high - speed serial bus that supports 127 devices in the chain.  USB uses a standard connector type that is used by most devices,  including mice,  printers,  network cards,  digital cameras,  and flash drives.  There are two USB standards : USB 1.1 , wh8ch had a transfer rate of 12 Mbps , and USB 2.0 , which had a transfer rate of 480 Mbps . There are two standard USB connectors,  type And Type B.  Type W connectors connect to the computer,  whereas Type B connectors connect to the device. 
IEEE 1394 (FireWire)  :- An ultra - high - speed bus that supports 63 devices in the chain and is ideal for real-time applications and devices such as for video.  FireWire has two standards : 1394a,  which has a transfer rate of 400 Mbps, and 1394b,  which has a transfer rate of 800 Mbps RS-232 :-  The standard for serial connections using the serial ports on a computer.  The serial port was a popular way to achieve a point-to-point connection between two hosts or was used for modems.  The RS-232 standard defines a transfer rate of 20,000 bits per second,  but serial devices support higher transfer rates.
