Computer Networks Questions & Answers – Topology
1. Physical or logical arrangement
of network is __________
a) Topology
b) Routing
c) Networking
d) None of the mentioned
a) Topology
b) Routing
c) Networking
d) None of the mentioned
Answer: a
Explanation: Topology in networks is the structure or pattern in which each and every node in the network is connected. There are many topologies in networking like bus, tree, ring, star, mesh, hybrid.

2. In which topology there is a
central controller or hub?
a) Star
b) Mesh
c) Ring
d) Bus
a) Star
b) Mesh
c) Ring
d) Bus
Answer: a
Explanation: In star topology a main hub is present to which all other nodes of the network is connected. Every data or information being transmitted or received in this topology has to pass through the hub. The hub directs the data to its destination.

3. This topology requires multipoint
connection
a) Star
b) Mesh
c) Ring
d) Bus
a) Star
b) Mesh
c) Ring
d) Bus
Answer: d
Explanation: In bus topology, there is a single cable to which all the network nodes are connected. So whenever a node tries to send a message or data to other nodes, this data passes through all other nodes in the network.

7. In TDM, slots are further divided
into __________
a) Seconds
b) Frames
c) Packets
d) None of the mentioned
a) Seconds
b) Frames
c) Packets
d) None of the mentioned
Answer: b
Explanation: TDM is the abbreviation for Time division multiplexing. It is technique for combining several low rate channel to a single high rate channel. For a certain time slot, the several channels could use the maximum bandwidth.
