What is terminator in bus topology?

What is terminator in bus topology?

A bus topology consists of a central cable — known as the backbone — that is used to connect all the devices. Terminators are used at the end of the cable, so that the electrical signal does not bounce back. Figure 1: Bus topology. In a bus topology, the signal sent via the main cable reaches all the connected devices.

How does a token bus network work?

Token bus is a network implementing a Token Ring protocol over a virtual ring on a coaxial cable. A token is passed around the network nodes and only the node possessing the token may transmit. If a node doesn’t have anything to send, the token is passed on to the next node on the virtual ring.

Is token bus still used?

Token bus networks are mainly used for industrial applications such as manufacturing. The IEEE 802.4 working group has disbanded, meaning that the standard is no longer being updated and not seeing wide use.

Why did token ring fail?

Probably the main reason why Token Ring failed however was pricing. IBM charged too much for royalties to vendors that wanted to produce Token Ring cards and MAUs. This made all Token Ring equipment too expensive. A Token Ring card could cost 5 and 6 times as much as an Ethernet card.

What are terminators in network?

(1) A device attached to the end-points of a bus network or daisy-chain. The purpose of the terminator is to absorb signals so that they do not reflect back down the line. Ethernet networks require a terminator at both ends of the bus, and SCSI chains require a single terminator at the end of the chain.

Which topology uses terminators?

bus topology
Terminators are used in bus topology.

Is token bus a LAN protocol?

Token Bus (IEEE 802.4) is a popular standard for token passing LANs. In a token bus LAN, the physical media is a bus or a tree, and a logical ring is created using a coaxial cable. The token is passed from one user to another in a sequence (clockwise or anticlockwise).

Which is IBM Token Bus?

4. Which of the following was the IBM Token bus? Explanation: The IBM Token bus was IEEE 802.4.

Why did Ethernet beat token-ring?

The token ring contains the routing information. Ethernet does not contain the routing information. Token rings are quite slow in terms of speed of data transmission, which is probably 16M bit/ sec. Ethernet is many times faster in terms of speed of data transmission, which is probably 100M bit/ sec.

Is terminator a media connector?

BNC connectors are associated with coaxial media and 10Base2 networks. BNC connectors are not as common as they once were, but still are used on some networks, older network cards, and older hubs. Common BNC connectors include a barrel connector, T-connector, and terminators.

What are terminators in networking?

(1) A character that ends a string of alphanumeric characters. (2) A hardware component that is connected to the last peripheral device in a series or the last node in a network.

Which of the following network uses terminator?

EXPLANATION. The correct answer to the question “Which Network topology requires terminators?” is letter A or bus network.

What is the difference between token ring and Token Bus?

Token Bus (IEEE 802.4) is a standard for implementing token ring over virtual ring in LANs….Differences between Token Ring and Token Bus.

Why is Ethernet better than Token Ring?

What is the difference between Token Ring and Token Bus?

What is the Terminator?

A Terminator, or T-Unit, is a type of Hunter-Killer designed to terminate other life forms. Various Terminators are built by an artificially intelligent computer called Skynet in order to wipe out the remains of the human race after Judgment Day.

What is an active terminator?

An active terminator is a type of single ended SCSI terminator with a built-in voltage regulator to compensate for variations in terminator power.
