Topology comes from the Greek terms topo and logy, which indicate ‘location’ and study. Topology is used in computer networks to describe how a network is physically connected and the logical flow of information. A topology is a diagram that shows how devices are connected and communicate with one another via communication lines. Topology transfers the data from one place to another in various types divided into other topologies like a star topology, mesh topology, bus topology, hybrid topology. Let us read about the meaning of line topology, all nodes are connected, and the straight-line connection in the article below.

There are primarily two types of topologies in computer Networks:

1. Physical Topology: In a computer network, a physical topology describes how computers or nodes are connected. It entails the deployment of devices, the installation of code, and the configuration of a computer network’s multiple elements (links, nodes, and so on) of a computer network. It’s the physical configuration of the network’s nodes, cables. And workstations, in other words.
2. Logical Topology: The way data flows from one computer to another is described by logical topology. It’s tied to a network protocol and determines how data travels over the network and its path. In other words, it’s the internal communication between the gadgets.

Meaning of line topology:

The host connects directly with all nodes over one bus line in a line topology, also known as daisy-chaining or bus topology. A regular Ethernet device or switch can be attached to the chain’s terminus and utilised normally. Be mindful that these devices will compete with the FieldDAQ device for network bandwidth. so this is the meaning of line topology. The bandwidth required by each device during operations must be considered while designing a reliable system. There are no additional links in this topology.

Advantages:

• Installing, expanding, and troubleshooting is simple and affordable.
• This topology is the best option for nodes with a small number of connections. A total of 15 nodes is suggested by NI, where all nodes are connected.
• There is no need for a separate switch.
• Long-distance travel ability.

Disadvantages:

• Unpowered nodes and node failure disrupt network communication.
• The addition or removal of any node causes network connectivity to be disrupted.
• Any Ethernet cable failure, as well as poor cable termination, causes network communication to be disrupted.
• When the number of nodes in a network surpasses 15, the performance and synchronisation suffer. Consider the star topology for systems that require a larger number of nodes.

Straight-line connections 

Network topology refers to how a network is organised, including the physical and logical descriptions of how connections and nodes are connected.

• Star Topology: 

In a star topology, which is the most popular network design, all nodes in the network are connected directly to one central hub through twisted-pair, coaxial, or fibre-optic cable. This central node acts as a repeater and a server, ensuring that data received from any network node reaches its intended destination.

• Bus topology: 

A bus topology arranges all devices on a network along a single wire that runs in a single direction from one end of the network to the other—hence the names “line topology” and “backbone topology.” The network’s data flow also follows the cable’s path, travelling in one direction.

• Ring topology: 

The nodes of a ring topology are arranged in a circle (or ring). The data can move in either one route or two directions across the ring network, with each device having precisely two neighbours.

• Tree topology: 

The tree topology structure gets its name because the network’s trunk is the central node, while nodes branch outward in a branch-like arrangement. The nodes are connected in a parent-child hierarchy in a tree topology, but each node is directly connected to the central hub in a star topology.

• Mesh topology: 

A mesh topology is a complex and extensive framework of point-to-point links that connects the nodes. Mesh networks are divided into two types: partial mesh and complete mesh. Partial mesh topologies are generally interconnected, with just two or three connections between a few nodes, whereas full-mesh topologies are entirely interconnected.

• Hybrid topology: 

The tree topology, which combines the bus and star layouts, is an example of a hybrid topology that combines two or more distinct topological structures. Individual departments have specialised network topologies suited to their demands and network usage in hybrid architectures, most popular in bigger corporations.

Conclusion:

The topology is simple to operate because of its centralised structure. It also ensures that each device in the network is isolated. It’s simple to add or remove network nodes, and it doesn’t have to affect the entire network. It is simple to identify defects in network devices due to their centralised structure. A network topology map is a diagram that shows the physical network structure of linked devices to an administrator. Knowing how devices link to one another and the best troubleshooting approaches is aided by a map of a network’s topology.
