Is a measure of frequency of failure and network recovery time after a failure?
Data Communication and Computer Networks – Computer Network Explanation : Reliability can be measured by a frequency of failure and network recovery time after a failure. In this case frequency of failure and network recovery time after a failure are the reliability issues.
Which is measured by the frequency of failure?
Failure rate is the frequency with which an engineered system or component fails, expressed in failures per unit of time. It is usually denoted by the Greek letter λ (lambda) and is often used in reliability engineering.
What is measured by the frequency of failure the link to a recovery after a failure and the network’s robustness in a catastrophe?
In addition to accuracy of delivery, network reliability is measured by the frequency of failure, the time it takes a link to recover from a failure, and the network’s robustness in a catastrophe.
Which of the following are network reliability issues?
Often when the people are ready to be productive, the network doesn’t cooperate. Avoiding all the jargon, the three most common causes (in no particular order) of network reliability issues are the following: poor/outdated infrastructure, congestion, and bad configuration.
What two main categories of network topologies are there?
Two basic categories of network topologies exist, physical topologies and logical topologies. The transmission medium layout used to link devices is the physical topology of the network.
What is a reliable network?
1. Capacity of the network to offer the same services even during a failure. Single failures (node or link) are usually considered since they account for the vast majority of failures.
Is TCP reliable or unreliable?
TCP provides reliable stream delivery of data between Internet hosts. Like UDP, TCP uses Internet Protocol, the underlying protocol, to transport datagrams, and supports the block transmission of a continuous stream of datagrams between process ports. Unlike UDP, TCP provides reliable message delivery.
Which network technology is more reliable?
Explanation: Ethernet cables, hubs, and switches are reliable, mainly because manufacturers have been continually improving Ethernet technology over several decades. Loose cables likely remain the most common source of failure in a wired network.
Which topology has the highest reliability?
Discussion Forum
| Que. | The topology with highest reliability is ? |
|---|---|
| b. | Star topology |
| c. | Ring Topology |
| d. | Mesh Topology |
| Answer:Mesh Topology |
Which network is more reliable client server or peer to peer?
Thus, client/server networks possess much more security than do peer-to-peer networks. Client/server networks also tend to be much more stable. In a peer-to-peer network, certain shared resources reside on each user’s machine. Servers can become very expensive.
Which of these is used to connect the two computers?
Ethernet cable
What is the advantage and disadvantage of peer to peer network?
5. Peer-to-Peer Network: advantages and disadvantages
| Advantages | Disadvantages |
|---|---|
| Much easier to set up than a client-server network – does not need specialist knowledge | Ensuring that viruses are not introduced to the network is the responsibility of each individual user |
What is the difference between a peer to peer network and a client to server network?
In Client-Server Network, Centralized server is used to store the data. While in Peer-to-Peer Network, Each peer has its own data. In Client-Server Network, Server respond the services which is request by Client. While in Peer-to-Peer Network, Each and every node can do both request and respond for the services.
What are the advantages of a server based network over Peer to Peer Network?
Following are the advantages of using a server-based network: It facilitates a Centralized storage system. Centralization makes administration easy. Data can be easily backed in such networks.
Which of the following is a disadvantage of a peer to peer network?
It is difficult to backup the data as it is stored in different computer systems and there is no central server. It is difficult to provide overall security in the peer to peer network as each system is independent and contains its own data.
What is the disadvantage of P2P networking?
P2P networks often suffer from performance issues. Each direct connection results in slower performance, even if the user of the terminal is not trying to access any other information except what is locally stored. This disadvantage is the primary reason why most peer to peer connections involve only two devices.
What are the disadvantages of client server network?
Disadvantages of Client Server Computing
- If all the clients simultaneously request data from the server, it may get overloaded.
- If the server fails for any reason, then none of the requests of the clients can be fulfilled.
- The cost of setting and maintaining a client server model are quite high.
What is the advantage and disadvantage of client server network?
3. Client-Server Network: advantages and disadvantages
| Advantages | Disadvantages |
|---|---|
| Backups and network security is controlled centrally | Specialist staff such as a network manager is needed |
| Users can access shared data which is centrally controlled | If any part of the network fails a lot of disruption can occur |
What are the advantages of client to server network?
The advantages of a client-server network are greater security of the network, more control e.g. network traffic passing through the network, being able to see what each computer is doing and limiting certain actions and preventing things such as viruses spreading, also the amount of data storage available to each …
