Due to the Uni-directional Ring, a data packet (token) must have to pass through all the nodes. If one workstation shuts down, it affects whole network or if a node goes down entire network goes down. It is slower in performance as compared to the bus topology.

What is the disadvantage of the ring topology?
The major disadvantage of a ring topology is that if any individual connection in the ring is broken, the entire network is affected. Ring topologies may be used in either LANs (local area networks) or WANs (wide area networks).
What are the advantages and disadvantages of a ring network topology?
It has better performance than bus topology, even when the nodes are increased. Ring network can handle high volume of nodes in a network (Robust). It can handle heavy traffic as compared to bus topology due to Token passing principal. Ring topology provides good communication over a long distance.
What is an disadvantage of a star network?
The disadvantages of a star network are: it is expensive to install as this type of network uses the most cable (network cable is expensive) extra hardware is required (hubs or switches) which adds to cost. if a hub or switch fails, all the devices connected to it will have no network connection.
Is a ring network reliable?
A ring network topology, in its pure form, offers poor reliability in case of both node and link failures. Rather than each node being connected to a central hub, in ring networks link segments connect adjacent nodes to each other. Each node passes the data it receives to the adjacent node.
What is network explain its advantages and disadvantages?
Advantages and disadvantages of networks
Files can easily be shared between users. Network users can communicate by email and instant messenger . Security is good – users cannot see other users’ files unlike on stand-alone machines. Data is easy to backup as all the data is stored on the file server .
What are the advantages and disadvantages of a bus network topology?
It works very efficient well when there is a small network. Length of cable required is less than a star topology. It is easy to connect or remove devices in this network without affecting any other device. Very cost-effective as compared to other network topology i.e. mesh and star.
Which of the following is are the drawbacks of ring topology Mcq?
Adding or removing the computers disturbs the network activity. If the central hub fails, the whole network fails to operate.
What are the advantages of token ring network?
Token Ring technology uses ring topology for data transfers and provides more advanced congestion management than that available in Ethernet. One of the major advantages of the Token Ring (TR) is no collision in the network and, therefore, utilization can reach 100% under heavy load.
What are the disadvantages of hybrid topology?
Disadvantages of Hybrid Topology :
- It is a type of network expensive.
- Design of a hybrid network is very complex.
- There is change hardware in order to connect topology with another topology.
- Usually hybrid architectures are usually larger in scales so they requires a lot of cables in installation process.
What is the ring network?
In a ring network each device (workstation , server , printer) is connected to two other devices – this forms a ring for the signals to travel around. Each packet of data on the network travels in one direction and each device receives each packet in turn until the destination device receives it.
What are the advantages of star and ring topologies?
Generally speaking, a star topology will deliver a more resilient network than a ring topology but does require more interfaces. As there is dedicated bandwidth to each switch, the bandwidth requirements of the links within a star topology will be lower than that of a ring.
What are the characteristics of ring topology?
In a ring topology, each node has a dedicated pointtopoint line configuration with the two nodes on either side of it. A signal is passed along the ring in one direction, from node to node, until it reaches its receiver. Each node in the ring is integrated as a repeater.
What are the disadvantages of a mesh topology?
Disadvantages of Mesh Topology :
- It’s costly as compared to the opposite network topologies i.e. star, bus, point to point topology.
- Installation is extremely difficult in the mesh.
- Power requirement is higher as all the nodes will need to remain active all the time and share the load.
- Complex process.
What must be avoided in a mesh network topology?
The disadvantages of a mesh topology are: fully connected mesh networks can be impractical to set up because of the high number of connections needed.
How collision is avoided in Token Ring?
Token Ring eliminates collision by the use of a single-use token and early token release to alleviate the down time. Ethernet alleviates collision by carrier sense multiple access and by the use of an intelligent switch; primitive Ethernet devices like hubs can precipitate collisions due to repeating traffic blindly.
Can advantages and disadvantages?
Advantages and disadvantages of CAN bus
| Advantages | Disadvantages |
|---|---|
| High speed data rate | Limited number of nodes (up to 64 nodes) |
| Low cost and light in weight and robustness | High cost for software development and maintenance |
| Supports auto retransmission for attribution lost messages | Possibility of signal integrity issues |
What are the disadvantages of computer networks?
List of Disadvantages of Computer Networking
- It lacks independence.
- It poses security difficulties.
- It lacks robustness.
- It allows for more presence of computer viruses and malware.
- Its light policing usage promotes negative acts.
- It requires an efficient handler.
- It requires an expensive set-up.
What are the advantages and disadvantages in using computer?
Advantages and Disadvantages of Using Computers | MIS
- Speed: The speed of carrying out the given instruction logically and numerically is incomparable between a computer and human being.
- Accuracy:
- Versatility:
- Reliability:
- Storage:
- Automatically:
- Compactness:
- Repetitiveness:
Is ring a network topology?
A ring network is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node a ring.
What are the advantages of buses?
The use of the bus for those trips has some advantages such as:
- Is less stressful.
- Travelling by bus is cheaper than owning and operating a car.
- Reduces pollution and road congestion the more people who travel by bus, the fewer cars on the road.
- You do not need to look for a place to park your card.
