Ethernet

Ethernet, also known as Fast Ethernet (when referring to speeds up to 100 Mbps), is the foundational technology for most Local Area Networks (LANs). It is widely used to connect devices in a network using cables, typically Twisted Pair Cables (such as Cat 5e or Cat 6) or Fiber Optic Cables. Ethernet provides reliable and efficient data transmission at speeds ranging from 10 Mbps to 100 Mbps in its traditional form.

Key Features of Ethernet:

  • Standardized Protocol: Ethernet follows IEEE standards, specifically IEEE 802.3, to define its specifications.
  • Medium: Can operate over copper twisted pair cables or fiber optic cables.
  • Transmission: Utilizes CSMA/CD (Carrier Sense Multiple Access with Collision Detection) to manage how data is sent over the network.

Ethernet has evolved over time, with improvements leading to higher speeds. While Ethernet (Fast Ethernet) and Gigabit Ethernet are distinct standards, they are not separate technologies but rather different versions of the Ethernet protocol. The next major version of Ethernet is Gigabit Ethernet, which offers faster data transmission rates.
