A network topology refers to the layout or structure of a computer network, defining how different nodes (such as computers, servers, switches, and routers) are interconnected. There are several types of network topologies, each with its own advantages and disadvantages. Here are some common network topologies:
Bus Topology:
In a bus topology, all devices are connected to a single backbone cable.
The backbone cable acts as a shared communication medium.
Devices communicate with each other by sending data packets along the bus.
It's simple and inexpensive but can suffer from issues like a single point of failure.
Star Topology:
In a star topology, each device is connected to a central hub or switch.
All data traffic flows through the central hub.
If one device fails, it doesn't affect the rest of the network.
It's easy to troubleshoot and expand, but the central hub can become a single point of failure.
Ring Topology:
In a ring topology, each device is connected to two other devices, forming a closed loop.
Data travels in one direction around the ring until it reaches its destination.
It's relatively easy to install and works well for small networks but can be problematic if one node fails, disrupting the entire network.
Mesh Topology:
In a mesh topology, every device is connected to every other device in the network.
There are two types of mesh topologies: full mesh and partial mesh.
Full mesh: Every node has a direct connection to every other node. It offers redundancy and fault tolerance but is costly and complex to implement.
Partial mesh: Only some nodes have direct connections to others. It provides redundancy without the high cost of a full mesh.
Mesh topologies are highly fault-tolerant and scalable but require a significant amount of cabling and configuration.
Tree Topology:
Also known as hierarchical topology, it resembles a tree structure with a root node at the top and branches connecting to other nodes.
It's commonly used in large networks like corporate networks, where it's easy to manage and expand.
However, it can suffer from a single point of failure if the root node fails.
Hybrid Topology:
Hybrid topology combines two or more different types of topologies.
For example, a network might use a combination of star and mesh topologies to balance cost, scalability, and reliability.
