Star topology - GCSE Computer Science Definition

A star topology is a type of network setup used in computer systems, where each device is connected to a switch or central hub. Imagine it like a wheel, with the switch as the centre and the devices like the wheel's spokes. This central switch acts as the controller, sending and receiving data between the connected devices. If one device wants to send information to another, the data first goes to the switch, which then directs it to the right place. One of the advantages of a star topology is that if one cable fails, it doesn't affect the rest of the network. However, if the switch itself fails, the whole network could go down. This topology is popular in homes and small businesses because it is easy to set up and manage.
