What is Ethernet and Types of Ethernet

Ethernet is an arrangement of technologies of networking and structure used in LAN (Local Area Networking), where computer systems are connected within a locality. Ethernet uses a Communication system that split data in different packets, which are known as frames. These frames (packets) include target and source address information, as well as tools, types, and devices used for detecting errors in conveying data and retransmission requests.

Ethernet is also said to be Gigabit Ethernet (GbE) in which Gb refers to the data transfer rate expressed in the units of 1,000,000,000 bps. This data transmitted in bundled units, even when there are delays in sources with one packet (frame). The speed of ethernet transmission is evolving and improving day by day for a better experience.

For example, 1000 BASE-T and 100 BASE-TX. These work at 100 Mbps and 1 Gbps respectively. 100 BASE-TX is also known as fast ethernet where many similar coaxial cables are replaced by corrupted pair cables, enabling faster frame transmission.

Carrier Ethernet is a high bandwidth system of technology used for access to the internet and connection by government, business and academic local area networks.

Metropolitan Ethernet is used by academic institutions, government entities, and corporations, etc.  It provides cost-effective and scalable solutions. Ethernet is basically used in Local Area Networks, Metropolitan Area Networks and Wide Area Networks. Ethernet was started at Xerox PARC between the years 1973 and 1974, inspired by the ALOH net, which Robert Metcalfe had studied as a part of his Ph.D. This idea was first written on 22 May, 1973 by Metcalfe. Who named it after the luminiferous aether. In 1975, Xerox charged a patent application recording Metcalfe.

TYPES OF ETHERNET

  1. Fast Ethernet

Firstly, Fast Ethernet was introduced in 1995 as the standard of IEEE 802.34 and it is the fastest ethernet version for three years before Gigabit Ethernet launched. It can carry traffic at the rate of 100 Mbps and the prior speed of ethernet is 10 Mbps. 100 BASE-TX is far the most common fast ethernet.

Now, it comes to the codification of fast ethernet so, “100” in the media refers to the speed of 100 Mbit/s, while “BASE” refers to the baseband signaling. The general design of this ethernet is an extension of 10 Mb standard of ethernet. It works on twisted pair cables or common fiber cables in a wired bus topology.

  1. Gigabit Ethernet

In the system of networking, Gigabit Ethernet (GbE or GigE) is a different technology of transferring packet at the speed of a gigabit per second (1,000,000,000 Gg per second). It is introduced at the beginning of 1999 by replacing fast ethernet also faster than that. The cables and machines, systems are most common in both ethernets. Many years ago, Half-duplex gigabit is used but for better technology full-duplex are used exclusively. Gigabit Ethernet has five standards of physical layers using optical fiber cables (1000 BASE-T) and shield cables (1000 BASE-CX).

  1. Switch Ethernet

Modern LANs have increasingly replaced the media sharing with a media of switched using switch ethernet. Basically, this ethernet uses switches and worked on the technology of switch. This decreased the bandwidth wastage which results from sharing the parts network packets which don’t need to take the data. This basically partitions the traffic to travel only on network segments. Every switch can be connected to each other, each one is broken off to other devices. It is also a major function in the wireless router and has up to 48 ports which any router has only four ports.
