What is Network Topology and What Are the Types of Topologies?
Network topology refers to the physical and logical arrangement of devices in a computer network. It determines how devices communicate and interact with each other. There are several types of network topologies, each with its own advantages and disadvantages.
Types of Topologies:
1. Bus Topology: - Devices are connected to a single shared cable. - Simple and inexpensive, but prone to network failure if the cable breaks.
2. Ring Topology: - Devices are connected in a circular fashion. - Data flows in one direction, ensuring high reliability but making it difficult to add or remove devices.
3. Star Topology: - Devices are connected to a central hub or switch. - Easy to manage and troubleshoot, but more expensive and requires additional hardware.
4. Mesh Topology: - Devices are connected to multiple other devices, creating multiple paths for data transmission. - Provides high reliability and bandwidth, but is complex and expensive.
5. Tree Topology: - A hierarchical arrangement where devices are connected in a parent-child relationship. - Provides clear network hierarchy and fault isolation, but can be complex to manage.
