# What is bus topology in data communication?

## What is bus topology in data communication?

Bus topology, also known as line topology, is a type of network topology in which all devices in the network are connected by one central RJ-45 network cable or coaxial cable. The single cable, where all data is transmitted between devices, is referred to as the bus, backbone, or trunk.

## What is the communication basis for bus topology?

Bus topology usually uses coaxial cable. In a ring topology, all stations are connected to the medium to form a single closed path (Fig. 6-7). Ring topology allows unicast, multicast and broadcast addressing.

What is the diagram of bus topology?

What is a Bus Topology? Bus topology definition is, this is one of the simplest physical topology used for the network. This topology is famously used for the Local Area Network. In this topology, all the nodes are connected through a single cable known as ‘Backbone’.

How the communication is done in a bus network?

How do bus networks work? Station devices connect to a bus network using physical network interface cards joined to a single cable — the bus — for transport to all other connected stations. When stations on the bus communicate, the data is broadcast to all devices on the bus.

### Where is bus topology used?

Bus network topologies are used when a small, cheap and often temporary network is needed that does not rely on very high data-transfer speeds. They may be used in locations such as a laboratory or office.

### What is bus in communication?

In computer architecture, a bus (shortened form of the Latin omnibus, and historically also called data highway or databus) is a communication system that transfers data between components inside a computer, or between computers.

What is the communication basis for bus topology Mcq?

Explanation: In bus topology, there is a single cable to which all the network nodes are connected. So whenever a node tries to send a message or data to other nodes, this data passes through all other nodes in the network through the cable.

What is the function of bus topology?

A bus topology connects computers along a single or more cable to connect linearly as figure 1. A network that uses a bus topology is referred to as a “bus network” which was the original form of Ethernet networks.

## Why is bus topology important?

Advantages of Bus Topology : It works very efficient well when there is a small network. Length of cable required is less than a star topology. It is easy to connect or remove devices in this network without affecting any other device. Very cost-effective as compared to other network topology i.e. mesh and star.

What are the features of bus topology?

In a bus topology, all nodes or devices are linked with one transmitter or server computer via a single cable (mostly coaxial cable) called backbone. All nodes are connected to the bus cable by drop lines. A drop line is a connection running between the nodes and the main cable.

What are some examples of bus topology?

Bus topology

• Ring topology
• Star topology
• Mesh topology
• Tree topology

Advantages of Bus Topology • Easy to connect a computer or peripheral to a linear bus. • Requires less cable length than a star topology. Disadvantages of Bus Topology • Entire network shuts down if there is a break in the main cable. • Terminators are required at both ends of the backbone cable.
