Computer Network Topology

Network topology is the arrangement of nodes and connecting lines in a computer network. It defines the structure and interconnections between various components, such as computers, routers, switches, and connections. Network topologies can be classified into two main categories: physical and logical. Physical topology shows the actual physical wired layout, while logical topology shows the logical network path along which data travels from one end to another.

Physical Topology

Point-to-Point Topology

Point-to-point topology is the simplest form of networking, connecting exactly two hosts such as computers, switches, routers, or servers. It provides swift and efficient transmission of data between network nodes, as it does not involve connecting multiple intermediate devices. Point-to-point networks are commonly used in settings like secure VPN tunnels between two sites and telecommunications.

Bus Topology

In bus topology, all devices share a single communication line or cable. It is a simple form of networking, where a failure of a device does not affect the other devices. However, failure of the shared communication line can make all other devices stop functioning. Bus topology either uses CSMA/CD technology or recognizes one host as the bus master to solve the issue.

Star Topology

Star topology is the most commonly used topology system. Every node connects to a central network device, like a hub, switch, or computer. It is centralized and user-friendly, reliable, and easy to manage. In star topology, data is sent in only one direction, and the terminator removes the data from the line once it reaches the extreme end.

Tree Topology

Tree topology is a variation of the star topology. It has a hierarchical flow of data. In tree topology, protocols like DHCP and SAC are used. It is a multi-point connection and a non-robust topology because if the backbone fails, the topology crashes.

Mesh Topology

Mesh topology is a fully or partially connected network. It allows for multiple paths between network nodes, improving network resiliency. In a fully meshed network, all nodes are connected to all other nodes, while in a partially meshed network, only some nodes have multiple connections with others.

Hybrid Topology

Hybrid topology is a combination of two or more topologies. It offers flexibility to different departments of an organization to implement a customized network topology mapping that is more suitable to their needs.

Logical Topology

Ring Topology

Ring topology is a cost-efficient topology with minimum chances of packet collision. In this topology, data is transmitted in a continuous ring, and each device connects to exactly two devices. However, failure of a single node can cause the entire network to fail.

Daisy Chain Topology

Daisy chain topology is a sequential series of network nodes. Data flows from one network node to another in a unidirectional manner. It has linear daisy chain and ring daisy chain subtypes.

In conclusion, network topology is a crucial aspect of computer networking, as it defines the structure and interconnections between various components. Understanding different topologies and their advantages and disadvantages can help in designing and managing efficient and reliable networks.
