Explain the differences between Bus Topology and Star Topology.?

Answer 1

why does it look like you need to write some assignments? :-)
I am not going to research my answer, but what I will write is pretty close to explaining it to you.
The bus topology is the notion of a all data going through a single broad path, and every pc on the network is connected to this path. One good way to visualise this is to imagine a wide road with cars on it. Exits on that road lead to various computers. Bus topology was quite popular till about a decade ago, but is now being replaced with the star topology.
In the star topology, there will be a central hub/bridge/switch and every computer is connected to it directly. To communicate with the other computers, you will need to go through the switch. This method lends itself well if we have dynamic number of PCs connected to the system.

Answer 2

A topology is the network configuration. The design or style determines the type of hardware you are going to use.

Bus topology: All devices are connected to a central cable, called the bus or backbone. Bus networks are relatively inexpensive and easy to install for small networks. Ethernet systems use a bus topology.

Star topology: All devices are connected to a central hub. Star networks are relatively easy to install and manage, but bottlenecks can occur because all data must pass through the hub

Answer 3

Bus topology

In a network, the master scheduler controls the data traffic. If data is to be transferred the requesting computer sends a message to the scheduler, which puts the request into a queue. The message contains an identification code which is broadcast to all nodes of the network. The scheduler works out priorities and notifies the receiver as soon as the bus is available.

The identified node takes the message and performs the data transfer between the two computers. Having completed the data transfer the bus becomes free for the next request in the scheduler's queue.

Bus benefit: any computer can be accessed directly and message can be sent in a relatively simple and fast way. Disadvantage: needs a scheduler to assign frequencies and priorities to organize the traffic.

Star networks are one of the most common computer network topologies. In its simplest form, a star network consists of one central switch, hub or computer which acts as a router to transmit messages. If the central node is passive, the originating node must be able to tolerate the reception of an echo of its own transmission, delayed by the two-way transmission time (i.e. to and from the central node) plus any delay generated in the central node. An active star network has an active central node that usually has the means to prevent echo-related problems.

Answer 4

The STAR topology has all the connections from a central point and they radiate outward. most HUB based systems are considered a star topology.

A BUS technology used to be the primary way that the Ethernet was connected to computers. The cable ran from computer to computer and had a terminator put on the last computer in the link. That was 10base2 wiring.

Answer 6

famous person this style of community topology wherein each and all of the nodes of the community is linked to a imperative node with a factor-to-factor link in a 'hub' and 'spoke' style, the imperative node being the 'hub' and the nodes that are linked to the imperative node being the 'spokes' (e.g., a determination of factor-to-factor links from the peripheral nodes that converge at a imperative node) – all documents it extremely is transmitted between nodes interior the community is transmitted to this imperative node, it extremely is often some style of device that then retransmits the information to some or all of the different nodes interior the community, in spite of the reality that the imperative node could additionally be an effortless easy connection factor (alongside with a 'punch-down' block) with out any lively device to repeat the indications. Ring this style of community topology wherein each and all of the nodes of the community is linked to 2 different nodes interior the community and with the 1st and final nodes being linked to a minimum of one yet another, forming a hoop – all documents it extremely is transmitted between nodes interior the community travels from one node to the subsequent node in a around way and the information often flows in a unmarried direction in elementary terms. Bus Linear bus this style of community topology wherein each and all of the nodes of the community are linked to a easy transmission medium which has precisely 2 endpoints (it extremely is the 'bus', it extremely is likewise often pronounced by way of fact the backbone, or trunk) – all documents it extremely is transmitted between nodes interior the community is transmitted over this easy transmission medium and is able to be gained via all nodes interior the community almost concurrently (brushing off propagation delays)
