Physical topology is a web constellation of the overseas telegrams, computing machines and other peripherals. Physical topology should non be confused, logical topology ; the attack is to go through information between workstations. Linear coach topology consists of a chief terminus at each terminal to run overseas telegrams. All nodes ( file waiter, workstations and peripherals ) connected to the additive overseas telegram.
Design star topology with each node ( file waiter, workstations and peripherals ) connected straight to a cardinal web hub, switch or concentrator. Datas on the stars through a web hub, switch or hub, and so go on to its finish. Hub, switch, or centralized direction and control of all maps of the web. It can besides be used as repeater informations watercourse. This constellation is common twisted-pair overseas telegram, but it can besides utilize coaxal overseas telegram or fiber ocular overseas telegram.
Features of the tree topology, combined with the additive coach and star topologies. It consists of groups of star constellation workstation connected to a additive coach anchor overseas telegram. Tree topology to let enlargement of bing webs, so that the school configure the web to run into their demands.
Advantages of a Linear Bus Topology:
- Easy to link a computing machine or peripheral to a additive coach.
- Requires less overseas telegram length than a star topology.
- Disadvantages of a Linear Bus Topology:
- Entire web shuts down if there is a interruption in the chief overseas telegram.
- Exterminators are required at both terminals of the anchor overseas telegram.
- Difficult to place the job if the full web shuts down.
- Not meant to be used as a stand-alone solution in a big edifice
Advantages of a Star Topology:
- Easy to put in and wire.
- No breaks to the web when connecting or taking devices.
- Easy to observe mistakes and to take parts.
Disadvantages of a Star Topology:
- Requires more overseas telegram length than a additive topology.
- If the hub, exchange, or concentrator fails, nodes attached are disabled.
- More expensive than additive coach topologies because of the cost of the hubs, etc
Advantages of a Tree Topology:
- Point-to-point wiring for single sections.
- Supported by several hardware and package sellers.
Disadvantages of a Tree Topology:
- Overall length of each section is limited by the type of telegraphing used.
- If the anchor line interruptions, the full section goes down.
- More hard to configure and wire than other topologies.
I recommend utilizing star topology, because it is easy to spread out the web to another concentrator, overseas telegram easy to put in, no web connexion break, easy to look into and cancel a portion of the mistake, and lower costs.
