Ethernet Port (RJ 45 Port)
Ethernet is a networking technology that is used to connect a computer to the Internet and communicate
with other computers or networking devices.
The interface that is used for computer networking (ethernet) and communication is known as Registered Jack
(RJ) and RJ-45 post, in particular, is used for Ethernet over cable. RJ-45 connector is an eight-pin connector.
The latest Ethernet technology is called Gigabit Ethernet and supports a data transfer rate of over 10 Gigabits
per second.
RJ-11
RJ-11 is another type of Registered Jack that is used as an interface for telephone, modem or ADSL connections.
It is the main interface in all telecommunication networks.
RJ-45 and RJ-11 ports look alike but RJ-11 is a smaller port and uses a 6-pin connector.
FireWire
FireWire is used with digital audio/video camcorders and personal computers (PC) and offers sustained data
transfer rates of over 3200 Mbits/s. FireWire was developed by Apple Inc. and integrated into Apple PCs as its
main communication interface. It is similar to a USB port that facilitates a high-speed connection between a
computer and peripheral devices.
