21.
Which network topology allows data to flow in a single direction from one node to another in a loop?
Correct Answer: C. Ring
One-liner
The Ring topology connects nodes in a circular loop where data travels in a single direction from one node to the next.
22.
What is a primary benefit of using a Star Topology in a network setup?
Correct Answer: A. A single computer failure does not bring down the whole network
One-liner
In a Star Topology, a single computer failure does not bring down the whole network because each node connects independently to a central hub or switch.
23.
What does network topology represent in computer networks?
Correct Answer: A. The arrangement of network connections
One-liner
Network topology represents the arrangement of network connections, describing how nodes are physically or logically interconnected.
24.
In which network topology is every device connected to a single main cable line?
Correct Answer: C. Bus topology
One-liner
In Bus topology, every device is connected to a single main cable line called the backbone.
25.
In a star topology network, each node is connected to which component that controls the network?
Correct Answer: D. Central minicomputer
One-liner
In a star topology, each node is connected to a central minicomputer (or hub/switch) that controls all network communication.
