What is Network Topology?

Network topology refers to the physical and logical arrangement of nodes and links in a computer network and governs how data flows between devices. It affects network performance, security, and scalability, making it an important concept in network design and management1.

Components of Network Topologies

Network topologies consist of two basic components: nodes and links.

Nodes: Connection points in a network that can send and receive data, such as computers, routers, switches, and IoT devices.

Links: The transmission medium used to send information between nodes, which can be wired or wireless.

Types of Network Topologies

Star Topology: All nodes are connected to a central hub.

Bus Topology: All nodes share a single communication line or data path.

Ring Topology: Each node is connected to two other nodes, creating a circular data path.

Mesh Topology: Each node is connected to multiple nodes, providing high redundancy and reliability.

Hybrid Topology: A combination of two or more different topologies.

Importance of Network Topology

Choosing the right network topology is important to maintain network reliability, security, and scalability. It also affects how efficiently data is transmitted and how easily the network can be expanded or modified.
