Network_Topology and its types BUS TOPOLOGY.pptx

Network topology
The physical layout or arrangement of connected devices in a network
Types of topologies
Bus Topology
simplest type of network topology
supports small number of computers
all computers or network nodes are connected to a central wire/medium
This medium is known as bus or backbone
The terminators are used at the end of a bus to absorb signals
A collision can occur in bus topology if two computers transmit data at the same time
Ring Topology
Star Topology
Tree Topology
Mesh Topology

1. N etwork topology Network Topology A network can be configured or arranged in different ways The physical layout or arrangement of connected devices in a network is... It is the shape of a network

2. Types of topologies Different network topologies are as follows: Bus Topology Ring Topology Star Topology Tree Topology Mesh Topology

3. Bus topology simplest type of network topology supports small number of computers all computers or network nodes are connected to a central wire/medium This medium is known as bus or backbone The terminators are used at the end of a bus to absorb signals A collision can occur in bus topology if two computers transmit data at the same time

4. Diagram of Bus Topology

5. Working of Bus Network The sending computer sends the data and destination address through the bus The data and address move from one computer to the other Each computer checks the address If it matches with the address of a computer, the computer keeps Otherwise the data moves to the next computer.

6. Advantages It is simple and easy to use. It requires small length of cable to connect computers. It is less expensive. If one node fails, it does not affect the rest of the...

7. Disadvantages It only supports small number of computers. The network speed slows down as the number of computers increases. A cable break can disable the entire network.
