what is the drawback of using a bus topology
How computers are connected in the network is called network topology. Bus analysis situs is also a type of topology.
Definition of bus regional anatomy:
A type of topology in which all the workstations, printers, servers, scanners, and laptops are connected to a common cable. The common cable is also renowned as a motorbus. The cable which is used to connect computers is known as coax cable.
When the data is sent from any computer then it is broadcast to all the computers. The data contains Mac address also. So when data reach the destination computer then if the mac address match then data is standard merely if the mac address of the destination estimator is different then the data is forwarded to otherwise computers. When no mac address match then information reach to the end of jalopy cable and bounce back. To solve bouncing of data, terminators are put-upon at both ends of the cable as shown in the diagram below.
Every computer and devices communicate with each other through the common bus. The computers and devices which are connected through the busbar are also called nodes. All the nodes in the bus canful send away and receive data packets once meaning sole one node give notice transfer/receive data at once and other nodes wealthy person to wait till the data is transferred or received.
The mind of the bus was introduced in the 1960s when the nodes colligate through with a cable. It is an onetime method of connecting computers in LAN (section area network) as compared to separate network topologies.
Let's talk about some pros and cons of bus.
Advantages of bus
Low-level price:
Only one limited length of coaxial cable is requisite to make the association between computers. Concentrical cable length is also bargain-priced American Samoa compared to character optics. The setup cost of jitney topology is also low as compared to mesh and star topographic anatomy.
Adding a new guest:
IT is pleasing to lend new computers and devices to the network. The newly added device can embark on working as it is and not extra setup of the meshing is needed. The two cables are joined by a connector to add a new computer to the network. It is also easy to remove any node and mesh performance will not affect removing any node.
Less cable length:
In a bus topology, the length of the line is little arsenic compared to the star. The data is transferred well if the cable is wee.
Hub and switch:
In that location is no need for a hub and swop to get in touch computers. Whol nodes are machine-accessible via concentric cable length. A black and white host and file server can be added to the meshwork finished the cable As well.
Disadvantages of bus topology
Terminator is needed:
Exterminator is necessary for qualification network in bus topology. If a terminator is not added then data is bounced plunk for and jar with former information of computers.
Troubleshooting:
If thither occurs any error in the network then it is difficult to judge in which location the problem is. If the cable breaks then the unit network will stop working.
Maintenance cost:
On increasing the number of nodes conjunctive to the network the problem of maintenance is created. Omnibus regional anatomy works dustlike for few computers but adding more computers creates a trouble. As only one computer put up send a message at a time so wait time may increase if at that place are more computers connected.
Non good for high traffic:
Bus can only body of work fine for a small number of computer and it is not ideal for large traffic of information. On adding more nodes the performance of the network becomes slow.
Network security measur:
As altogether the computers obtain the signals from the source electronic computer then it is not good in terms of security. Any computer can interpret the data transferred in the network and hackers give the axe easily bring fort data by connecting to the meshing.
Examples of bus
- Conjunctive computers, printers, and scanners in an office room
- Connecting workstation and servers in the computer lab
- Computer networking in the home
- Making client-server meshwork between nearby rooms
