Things that you will learn here:

Ethernet

Ethernet is a widely adopted networking standard for wired LANs, and it’s also utilized in MANs and WANs. It has replaced older technologies like ARCNET and Token Ring. Despite its name, Ethernet isn’t confined to wires; it’s also employed over fiber-optic connections.

This standard governs how data is transmitted, errors are managed, and network performance is maintained. It establishes guidelines for setting up Ethernet networks and governing interactions among network components.

In the OSI model, Ethernet operates at the data link and physical layers, and it laid the groundwork for the IEEE 802.3 Standard, which streamlined network and hardware development.

Initially, Ethernet supported a modest data rate of 2.94 Mbps, but it has since evolved significantly. Today, it supports speeds ranging up to 400 Gbps, driven by the need for faster data transmission.

Fast Ethernet

Fast Ethernet, defined by the IEEE 802.3u standard, was created to achieve data transmission speeds up to 100 Mbps. It’s also known as the 100BASE-TX standard.

Gigabit Ethernet

Gigabit Ethernet, specified by IEEE 802.3ab, was designed to facilitate high-speed communication networks capable of supporting services such as streaming multimedia and Voice over IP (VoIP). Operating under the 1000BASE-T standard, it runs at speeds ten times faster than its predecessor, 100BASE-TX.

Gigabit Ethernet has become a standard part of the 802.3 framework and is highly recommended for enterprise networks. Importantly, it maintains backward compatibility with both the 100BASE-T and older 10BASE-T standards, ensuring seamless integration with existing infrastructure.

10 Gigabit Ethernet

The 10 Gigabit Ethernet standard, defined by IEEE 802.3ae, achieves a data transfer speed of 10 Gbps, representing a tenfold increase over previous standards. This enhanced speed is exclusively attainable through fiber optic technology.

To optimize efficiency, the standard mandates area-based routing for 10-Gigabit Ethernet networks instead of broadcasting data to all nodes. This approach effectively minimizes network noise and reduces overall traffic congestion, enhancing the network’s performance and reliability.

Terabit Ethernet

Terabit Ethernet represents the next leap in networking speeds, offering impressive data transfer rates of 200 Gbps and 400 Gbps initially. Future advancements are anticipated to push these speeds even higher, potentially reaching 800 Gbps and 1.6 Tbps.

This advancement in Ethernet technology is poised to meet the escalating demands of data-intensive applications, supporting faster communication and data processing across networks.
