Advanced ethernet – Networking concepts Video Tutorial

Advanced Ethernet – Networking – Network involves connection of computers, workstations and peripheral devices such as routers, switches, bridges and hubs. These devices are interconnected with the help of a medium. There are several types of networks such as Local Area Networks, Wide Area Networks and so an.

3. identify different types of high speed Ethernet standards

Definition – What does 5-4-3 Rule mean?

The 5-4-3 rule is a guideline used in the design of shared Ethernet networks which promotes optimal traffic flow. This refers to the number of repeaters and segments that must be present on shared Ethernet backbones set up in a tree topology. The rule states that there should be a maximum of five segments which are connected by four repeaters, and only three of those segments can contain active senders/terminals.

Explains 5-4-3 Rule

The Ethernet protocol dictates that data sent over the collision domain must reach every part on its path toward its destination within a specified length of time. However, each repeater and segment that the signal passes through adds a certain amount of time in the process. The rule was created in the early days of the Ethernet when 10Base5 and 10Base2 were the only Ethernet types available, and shared access backbones were quite slow. The 5-4-3 rule was designed to minimise signal transmission time.

what is 10 Base – T..?

One of several adaptations of the Ethernet (IEEE 802.3) standard for Local Area Networks (LANs). The 10Base-T standard (also called Twisted Pair Ethernet) uses a twisted-pair cable with maximum lengths of 100 meters.

10BaseT Standard. The IEEE committee published the 802.3 specification for running Ethernet over twisted pair wiring in 1990. This 10BaseT (10 Mbps, baseband, over twisted pair cable), is an Ethernet network that typically uses unshielded twisted pair (UTP) cable to connect computers.
