First network topology refers to how computers and other DEVICES such as scanner are arranged to transfer DATA within a network Typesbus topologyStar topology Ring topology Mesh topology Explanation::-In bus topology the devices are all connected to the central backbone at the end there is a terminator used : to connect many but limited devices in a small local area for instance schools and offices:- In star topology the devices form a star like structure where each device is connected to the central concentrator used:to connect devices in small area example at homes and hospitals SINCE it is very expensive due to the presence of concentrator so it is not widely used :- In ring topology devices are connected in a ring like structure ie each device is connected to the other to form a circle:-In Mesh topology each device is connected to ANOTHER in the network. It is difficult to configure since all devices must be connected to each other :-Tree topology is a combination of star and bus topology used:in LARGE areas since sooo many computers and devices can be connected I hope it helped
