Summary 📝
A network topology is the way devices (nodes) are arranged and connected in a network.
In a star topology, all devices are connected to a central switch or hub.
If one device fails, the others keep working.
Easy to add new devices.
If the central hub fails, the whole network stops.
Key learning Points 📌
In a bus topology, all devices share a single cable (called the bus).
Cheap and easy to set up for small networks.
If the main cable fails, the network goes down.
Can be slow if too many devices are using it at once.
Star networks are more reliable and faster, but cost more.
Bus networks are cheaper but can be less reliable.
