Star topology
A network topology where all devices are connected to a central hub or switch.
Mesh topology
A network topology where devices are interconnected, allowing multiple paths for data to travel.
Advantages of star topology
Easy to add/remove devices, centralised management, and failure of one device does not affect others.
Disadvantages of star topology
If the central hub or switch fails, the entire network goes down.
Advantages of mesh topology
Highly reliable as there are multiple paths for data, and it can handle high traffic effectively.
Disadvantages of mesh topology
Expensive to set up due to the large number of connections and complex maintenance.
Central hub in star topology
The device that manages communication between all connected devices in a star topology.
Data redundancy in mesh topology
Mesh topology provides data redundancy by offering multiple paths for data transmission.
Scalability of star topology
Star topology is scalable as devices can be added easily without affecting the network.
Complexity of mesh topology
Mesh topology is complex to set up and maintain due to the large number of connections.
