Ethernet is a communication technology that is mostly used to establish local area networks. It uses cables to send and receive data. This allows network communication between two or more types of network cables, such as copper to fibre optic and back.

Networks throughout the 1960s and 1970s were haphazard jumbles of technology with little rhyme or rationale. But then Xerox's Palo Alto Research Center asked Robert "Bob" Metcalfe to set up a local-area network (LAN) (PARC). Ethernet, his invention, revolutionised everything.

Ethernet is a technology that is used to transmit data in networks. The benefits of using Ethernet are many. It is more reliable than Wi-Fi, so service will not be interrupted by signal interference. Moreover, it allows for higher speeds than Wi-Fi and uses less power than Wi-Fi.

Ethernet is an old networking technology that has been around for about 30 years. It’s based on the CSMA/CD protocol, which stands for Carrier Sense Multiple Access with Collision Detection. That means it uses a method of sharing bandwidth where the network cards on each computer take turns transmitting data packets. The other type of protocol is CSMA/CA, which stands for Carrier Sense Multiple Access with Collision Avoidance. WiFi networks are based on this protocol and they use a different method of sharing bandwidth which avoids collisions by using an algorithm that allows computers to transmit data packets at the same time, without any interruptions.

Ethernet was created in 1973 by a team at the Xerox Corporation's Palo Alto Research Center (Xerox PARC) in California. The team, led by American electrical engineer Robert Metcalfe, sought to create a technology that could connect many computers over long distances.
