Network topology
Network topology refers to the arrangement of various elements (links, nodes, etc.) in a computer network. It is a crucial aspect of network design and can significantly impact the performance, scalability, and reliability of the network.
Types of Network Topologies[edit | edit source]
Network topologies can be broadly classified into two categories: physical topology and logical topology.
Physical Topology[edit | edit source]
Physical topology refers to the physical layout of the network, including the arrangement of cables, computers, and other peripherals. Common types of physical topologies include:
Bus Topology[edit | edit source]
In a bus topology, all devices are connected to a single central cable, known as the bus. Data sent from a device travels along the bus until it reaches its destination.
Star Topology[edit | edit source]
In a star topology, all devices are connected to a central hub or switch. Data sent from a device travels to the hub, which then forwards it to the destination device.
Ring Topology[edit | edit source]
In a ring topology, each device is connected to two other devices, forming a circular data path. Data travels in one direction around the ring until it reaches its destination.
Mesh Topology[edit | edit source]
In a mesh topology, each device is connected to every other device in the network. This provides high redundancy and reliability, as there are multiple paths for data to travel.
Tree Topology[edit | edit source]
A tree topology is a hierarchical structure where groups of star-configured networks are connected to a linear bus backbone. This topology combines characteristics of both bus and star topologies.
Hybrid Topology[edit | edit source]
A hybrid topology is a combination of two or more different types of topologies. It leverages the strengths and mitigates the weaknesses of the constituent topologies.
Logical Topology[edit | edit source]
Logical topology refers to the way data flows within a network, regardless of its physical design. Common types of logical topologies include:
Importance of Network Topology[edit | edit source]
Network topology plays a critical role in determining the performance and reliability of a network. It affects:
