In which network topology does the failure of the main backbone cable result in the entire network becoming non-functional?
Answer:
Bus
In a bus topology, all devices are connected to a single central cable, known as the backbone or trunk. If this main cable breaks or experiences a fault, the entire network segment loses connectivity because the signal can no longer propagate to the other devices on the network.
52
Which of the following options represents a standard type of network topology?
Answer:
All of the above
Network topology refers to the physical or logical arrangement of devices and connections in a network. Common types include Star, where nodes connect to a central hub; Ring, where nodes form a closed loop; and Bus, where all nodes share a single communication line. All three are recognized standard topologies in networking.
53
Which of the following is a recognized network topology?
Answer:
Bus
A bus topology is a network setup where all nodes are connected to a single central cable, known as the backbone or bus. Data transmitted by a node travels along the cable and is received by all other nodes on the network.
54
Which of the following is not recognized as a standard network topology?
Answer:
Circle
Common network topologies include Star, Ring, Bus, Mesh, and Tree. 'Circle' is not a standard term used to describe the physical or logical layout of a computer network, whereas the others represent established methods for connecting network nodes.
55
In which network topology are all peripheral nodes connected to a single central hub or switch?
Answer:
Star topology
In a star topology, every individual node is connected to a central connection point, such as a switch or hub. This central node acts as a conduit to transmit messages, making it easy to manage and isolate faults within the network.
56
Which of the following configurations is recognized as a type of network topology?
Answer:
All of these
Network topology refers to the physical or logical arrangement of a network. Bus, Star, and Ring are all standard, well-defined topologies used to connect devices within a computer network infrastructure.
