explain any three topology?
Answers
Answer:
Computers in a network have to be connected in some logical manner. The layout pattern of the interconnections between computers in a network is called network topology. ... There are a number of different types of network topologies, including point-to-point, bus, star, ring, mesh, tree and hybrid.
Star – All computers and devices are connected to a centrally located hub or switch. The hub or switch collects and distributes the flow of data within the network. It’s better to use a switch than a hub because a switch transmits the data to the intended recipient rather than to all hosts on a network.
Bus – All computers and devices are connected in series to a single linear cable called a trunk or sometimes called a backbone. Both ends of the trunk must be terminated to stop the signal from bouncing back up the cable. Because the bus topology does not have a central point it is difficult to troubleshoot problems. Also, a break at any point along the bus can cause the entire network to go down.
Ring – In this topology, all computers and devices are connected to cable that forms a closed loop. Each computer on this type of topology acts like a repeater and boosts the signal before sending it to the next computer. It transmits data by passing a “token” around the network. Hence this type of network is commonly called a token ring network. Similar to the Bus topology, if one computer fails, the entire network goes down.
Explanation:
In a ring network, every device has exactly two neighbouring purpose.
- It's called a ring topology as its conformation is like a ring.
- In this topology, every computer is connected to another computer. Then, the last knot is combined with a first one.
Ring topology uses commemorative to pass the information from one computer to another. In this topology, all the dispatches travel through a ring in the same direction.
In the star topology, all the computers are connected with the help of a hub.
- This string is called a central knot, and all other bumps are connected using this central knot.
- It's most popular on LAN networks as they're affordable and easy to install.
The mesh topology has a unique network design in which each computer on the network connects to every other.
- It's develops a P2P( point- to- point) connection between all the bias of the network.
- It offers a high position of redundancy, so indeed if one network string fails, still data has an indispensable path to reach its destination.
