Topology is the study of the properties of space that are preserved under continuous transformations. In mathematics, topology is concerned with the study of the properties of objects that are unchanged by stretching, bending, or other types of deformation.
In computer networking, topology refers to the way in which the devices in a network are connected to each other. There are several common types of network topologies, including:
Bus topology: In a bus topology, all devices are connected to a single cable, which acts as a backbone for the network. Data is transmitted between devices by broadcasting it over the cable.
Star topology: In a star topology, each device is connected to a central hub or switch. Data is transmitted between devices by sending it to the hub or switch, which then forwards it to the appropriate device.
Ring topology: In a ring topology, each device is connected to two other devices in a circular chain. Data is transmitted between devices by passing it from one device to the next in the ring.
Mesh topology: In a mesh topology, each device is connected to every other device in the network. Data is transmitted between devices by sending it directly to the destination device.
The choice of network topology depends on factors such
as the size of the network, the distance between devices, and the amount of
traffic on the network. Each topology has its own advantages and disadvantages
in terms of performance, reliability, and cost.
In summary, topology is the study of the properties of
space that are preserved under continuous transformations, while in computer
networking, topology refers to the way in which devices are connected in a
network. Understanding different types of network topologies is important for
building efficient and reliable computer networks.
