What is Ethernet

What is Ethernet?

What is EthernetEthernet is such a widely used tern in the computer and technology world. But what is Ethernet really? How is it different from Internet?

Ethernet is a group of computer systems linked to form a local area network (LAN), a metropolitan area network (MAN) or a wide area network (WAN). Ethernet is a network that allows file sharing between computers, computers and printers, etc.

While Ethernet created a LOCAL network, the Internet is a GLOBAL one.

History

It was developed at Xerox PARC in the 1970’s and with time replaced other local area network technologies including Token Ring and Token Bus. Ethernet’s advantage over other technologies was its ability to adapt to market realities and switch to inexpensive and ubiquitous twisted pair wiring. By the 1990’s Ethernet was so wide spread it became a must have feature for modem computers, and some computers started being designed with Ethernet ports, as well as most workstations. 10BASE-T and its smaller modular connector have sped up this process.

Developments

Initially, the 10BASE5 Ethernet used coaxial cables. Today’s Ethernet alternatives use twisted pair (Ethernet cable) and fiber optic links with hubs or switches. Ethernet data transfer rates have increased from 2.94 megabits/sec to 100 gigabits/sec.

Over time and due to growing demand and use, Ethernet technology has evolved to meet new bandwidth and market standards. Now days Ethernet is used to connect computer networks, as well as to interconnect appliances and other personal devices and in industrial applications.
Ethernet have been through numerous improvements and changes over the years.
