What is network topology ?

Network topology refers to the physical or logical layout of a network. It defines how devices, such as computers, servers, routers, and switches, are connected to each other and how data is transmitted between them. There are several types of network topologies, including bus, ring, star, mesh, and hybrid topologies, each with its own advantages and disadvantages. The choice of network topology depends on factors such as the size of the network, the type of devices being used, and the desired level of redundancy and scalability.
