What are Computer Network topology and what types of network topology?

Admission Open

The configuration of how computer systems or network devices are in relation to one another is a topology. Additionally, topologies help to attain information about a network's exact specifications. A network may have the same or different logical and physical topologies.

It helps determine the connection between more than one network. They are an essential part of computer hardware and networking.

Bus Topology

  • All of the stations of the computer network are in unison by a single cable known as a backbone cable thanks to the bus topology's design.
  • Either a drop cable or a direct connection to the central node connects each node to it.
  • A node puts communication over the system whenever it wishes to transmit a message. Regardless of how it has all the features, the message will reach every station in the network.
  • A computer networking coursewill teach you that, most 802.3 (ethernet) and 802.4 standard systems use the bus topology.
  • In comparison to other topologies, the implementation of a bus topology is very straightforward.
  • The signal is there for all the stations via the backbone cable, which is popular as a "single lane."

Features of Bus Topology

  • Cheap cable: In a bus topology, nodes and cables are directly one bypassing a hub. As a result, the installation has a minimal initial cost.
  • Coaxial or twisted pair cables are typically utilised in bus-based networks that offer up to 10 Mbps for moderate data rates.
  • Technology that is well-known: Bus topology is a well-known technology since hardware components are readily available and installation and troubleshooting methods are well-known.
  • A computer networking course will teach you that, most 802.3 (ethernet) and 802.4 standard systems use the bus topology.
  • One node's failure will only have a limited impact on the other nodes

Star Topology

Star Topology connects several nodes to the computers with ease.

When compared to the bus topology, troubleshooting in a star topology is far more effective. The manager must examine the kilometres of cable in a bus topology. All of the stations are in a central network in any star topology. As a result, the network administrator must visit the single station to investigate the issue.

Network control: The star topology makes it simple to incorporate sophisticated network control capabilities. Any modifications to the star topology are automatically taken into account.

It is a strong unit of connection between the server and the nodes.

Since each station has its own connection connecting it to the central hub, a cable failure won't affect the entire network.

Due to the low cost of its tools, star topology is the main technology.

As more stations may be available to the hub's open ports, it is easily extendable. Star topology systems are economical because they use coaxial cable, which is readily available. A bandwidth of about 100 Mbps is available there. One of the most often used Star topology networks is Ethernet 100BaseT.

All of the connected nodes won't be able to interact with one another if the centralized location or switch fails.

When a lot of cable routing is necessary, it can occasionally become challenging.
