what is the difference between ring network and bus network?

A Bus topology is a network topology in which all nodes connect to the network via a central cable, , called the bus. ... In a Ring topology every device/node is connected to exactly two other nodes one on either side of it in closed loop fashion.

In wide area networks (WAN) and meteropolitan area networks (MAN), a ring topology is used to as the topology for the backbone (sometimes called a city ring) to connect the customers. In that case the ring is used in both directions to have two distinctive paths to the public switch.

Network connects thousands of PC, at one-time while the Internet connects millions of computers at one time. ... The Network is a collection of computer systems and devices that are linked together using LAN, WAN, CAN, or HAN whereas the Internet is a global system to link various types of electric devices worldwide.

So, in short, a hub glues together an Ethernet network segment, a switch can connect multiple Ethernet segments more efficiently and a router can do those functions plus route TCP/IP packets between multiple LANs and/or WANs; and much more of course.

Mainly size. Ring roads are usually miles in length and tend to take you around a large area such as a town or other large, often built up area etc. Roundabouts are a form of junction designed to deal with several merging roads usually devoid of traffic lights.

['There are five types of topology in computer networks: ... ', 'In mesh topology each device is connected to every other device on the network through a dedicated point-to-point link. ... ', 'In star topology each device in the network is connected to a central device called hub.']

FDDI uses a dual ring topology. The dual ring topology uses two counter-rotating rings known as the primary and secondary ring. The primary ring is similar to the main ring path in token-ring terminology.

Ans: Network topology is the physical design of a LAN which resolves the conflict that occurs between computers on the network attempting to transmit at the same time. Whereas protocols are the standards used by networks to permit communication between network-connected devices.

Disadvantages of Ring Topology The failure of a single node in the network can cause the entire network to fail. The movement or changes made to network nodes affect the entire network's performance. Data sent from one node to another has to pass through all the intermediate nodes.

Reduced chances of data collision as each node release a data packet after receiving the token. Token passing makes ring topology perform better than bus topology under heavy traffic. No need of server to control connectivity among the nodes. Equal access to the resources.

['The cable length is limited. ... ', 'This network topology can perform well only for a limited number of nodes. ... ', 'It is suitable for networks with low traffic. ... ', 'It is heavily dependent on the central bus. ... ', 'It is not easy to isolate faults in the network nodes.']

Unlike Mesh topology, star topology doesn't allow direct communication between devices, a device must have to communicate through hub. If one device wants to send data to other device, it has to first send the data to hub and then the hub transmit that data to the designated device.

Although FDDI logical topology is a ring-based token network, it did not use the IEEE 802.5 token ring protocol as its basis; instead, its protocol was derived from the IEEE 802.4 token bus timed token protocol.

As mentioned above, a hub only contains the basic function of a switch. ... For instance, hub is a passive device without software while router is a networking device, and data transmission form in hub is in electrical signal or bits while in router it is in form of packet.

Physical topology refers to how physical devices are placed and connected together with cables. In contrast, logical topology is about how data and information flows within the network. ... Ring – Each node in a ring topology connects to exactly two other nodes.

There are three major system bus types that can be identified based on the type of information they carry. These include the address bus, data bus, and control bus. The address bus is a uni-directional pathway, which means that information can only flow one way.
