the first work which deserves to be considered as the beginnings of topology is due to Euler. In 1736 Euler published a paper on the solution of the Königsberg bridge problem which translates into English as The solution of a problem relating to the geometry of position .
The configuration of a communication network of Computer Science in which the arrangement in nodes of a LAN is connected to each other is known as Topology. It is a term which defines Topology in a simple manner.
StarTopology. Bus Topology Ring/Network Topology Tree/Extended Star Topology.
This type Topology is often called a multi-port repeater. In a star topology, each device has a dedicated point to point link only to central controller, usually called a hub/server/host.
Advantages- Disadvantages- Easy to install Requires more and wire. cable length than a linear Easy to detect topology. . More faults and to remove parts. expensive.
The bus topology is the simplest and most common. It is often used when a network installation is small, simple, or temporary.
Advantages- Disadvantages- In an active topology Heavy network traffic network, the computers can slow a bus regenerate signals and considerably. are responsible for moving the data through the network. On a bus network, all the computer are A break in the cable or connected to a single lake of proper cable. termination can bring the network down.
In a ring topology, each computer is connected directly to the next computer in line, forming a circle of cable. It uses token to pass the information from one computer to another.
Advantages- Disadvantages- All the computers Failure of one have equal access to computer can affect the network. the whole network. Even with many It is difficult to users, network troubleshoot the ring performance is even. network. Adding or removing Allows error computers disturbs checking, and the network . acknowledgement.
Among all the Network Topologies the Tree Topology is a combination of the bus and the Star Topology.
Advantages- Disadvantages- Overall length of Point-to-point wiring for each segment is individual segments. limited by the type of cabling used. If the backbone line Supported by breaks, the entire several hardware segment goes down. and software More difficult to venders. configure and wire than other topologies
The Network of Topology differs from place to place. But, however, all of them have their advantages & disadvantages. If the server problem occurs or server gets down, then Topology faces its failure
