a bus network is like a road with bus stops. the data stops at every computer this is easy to do but very slow. if the main cable fails or gets damaged the whole network will fail

Star Network

a star network is were every computer is connected to a sentral server some advantages of this are: its very reliable – if one cable or device fails then all the others will continue to work and high performing as no data collisions can occur. Some Disadvantages are it`s expensive to install as this type of network uses the most cable (network cable is expensive) and if a hub or switch fails all the devices connected to it will have no network connection
