Network Topologies
A network topology is a visual representation of a computer network that shows how devices are connected to each other. It provides a high-level understanding of the network's structure and how data is exchanged between devices.
Types of Network Topologies:
Star topology: All devices are connected to a single central hub.
Bus topology: All devices are connected to a single cable, which runs throughout the network.
Ring topology: Devices are connected in a circle, with data traveling around the ring in a clockwise direction.
Mesh topology: Devices are connected to each other directly, creating a mesh.
Wireless topology: Devices communicate with each other using wireless signals.
Benefits of Using a Specific Topology:
Scalability: Star and bus topologies are easy to scale, while mesh and wireless topologies are more scalable for large networks.
Security: Star and bus topologies are more secure than other topologies, as it is difficult for an attacker to isolate a single device.
Cost: Star and bus topologies are typically the cheapest to implement, while wireless and mesh topologies can be more expensive.
Examples:
In a star topology, a computer is connected to a hub via a cable.
A bus topology consists of multiple cables connected to a single switch or hub.
A ring topology is commonly used in LANs (Local Area Networks), where devices are connected in a circle.
A mesh topology is used in wide area networks (WANs) for high-performance communication.
In a wireless topology, devices communicate using wireless signals, such as Wi-Fi
