Network topologies refer to the physical layout of nodes and cables in a network. These layouts determine how data is transmitted between devices and how the network is divided into smaller subnets.
A ring topology consists of a central hub connecting multiple devices. The hub acts as a single point of failure, and any device can communicate with the others directly.
Example: A computer network with a ring topology would be used in a lecture hall where the instructor is at the center and students connect to the hub to participate.
A star topology is similar to the ring topology but with a central device (star) that controls access to the network. The star has one central hub that broadcasts signals to all devices connected to it.
Example: A computer network with a star topology would be used in a school network where the principal's computer acts as the central hub.
A mesh topology consists of multiple switches and routers connected directly to the devices in the network. This allows for redundant connections, ensuring that data can be transmitted between any two devices.
Example: A computer network with a mesh topology would be used in a large office building where multiple servers and workstations are connected to the network.
A bus topology consists of a single cable that connects all devices directly to the hub. This is the simplest topology but is also the least efficient, as data must travel the entire length of the cable.
Example: A computer network with a bus topology would be used in a small home network where all devices are connected to a single cable that runs through the house
