Network Topologies
Network topologies refer to the physical arrangement of devices (like computers, routers, switches) in a network. The topology determines how information flows and the overall efficiency of the network. Here are some common topologies:
Bus Topology: Imagine a single cable running through all devices in a network. This is a bus topology. If one device fails, the entire network can be disrupted. It’s simple to set up but less reliable.
![](https://i0.wp.com/afzalbadshah.com/wp-content/uploads/2024/09/Computer-Networks-Bus-Topology-jpg.webp?resize=484%2C175&ssl=1)
Ring Topology: In a ring topology, devices are connected in a circular fashion, forming a ring. Data flows in one direction around the ring. If one device fails, the entire network can be disrupted, but there are mechanisms to bypass faulty devices.
![](https://i0.wp.com/afzalbadshah.com/wp-content/uploads/2024/09/Computer-Networks-Ring-Topology-jpg.webp?resize=404%2C335&ssl=1)
Star Topology: In a star topology, all devices are connected to a central hub or switch. This is like a star with the hub at the center. If one device fails, the rest can continue to operate. It’s more reliable than bus topology but can be more expensive due to the central hub.
![](https://i0.wp.com/afzalbadshah.com/wp-content/uploads/2024/09/Computer-Networks-Star-Topology-jpg.webp?resize=330%2C295&ssl=1)
Mesh Topology: In a mesh topology, every device is connected directly to every other device. This provides high redundancy and fault tolerance, but it requires a large number of cables and can be complex to manage.
![](https://i0.wp.com/afzalbadshah.com/wp-content/uploads/2024/09/Computer-Networks-Mash-Topology-jpg.webp?resize=330%2C295&ssl=1)
Classification of Networks
Networks can be classified into different types based on their size, geographical coverage, and purpose. Here are some common classifications of networks:
