Computer Networks Questions
-
Mesh topology
-
Star topology
-
Bus topology
-
Ring topology
-
Tree toplogy
A
Correct answer
Explanation
In mesh topology, every device connects to every other device. Hence, if any link in the network fails, the whole network does not fails. So, it is the most reliable network.
-
Star topology
-
Mesh topology
-
Bus topology
-
Ring topology
-
Tree topology
B
Correct answer
Explanation
This option is correct because in mesh topology, there is no central hub or a central cable. Every node in the network is connected to every other node in the network.
-
Repeaters
-
Bridges
-
Routers
-
Protocols
-
Switch
A
Correct answer
Explanation
This option is correct as repeaters are used in transmission systems to regenerate analog or digital signals, distorted by transmission loss. This improves the signal quality, and the unwanted noise is removed.
-
Partial mesh topology
-
Full mesh topology
-
Star topology
-
Ring topology
-
Bus topology
A
Correct answer
Explanation
This option is correct because in partial mesh network, only those nodes are connected to each other, which exchange most of the data.
-
Broadcasting
-
Hierarchical routing
-
Multicast routing
-
Distance vector routing
-
Link state routing
A
Correct answer
Explanation
This option is correct as broadcasting refers to transmitting a packet that will be received by every device on the network.
-
ring topology
-
bus topology
-
tree topology
-
star topology
-
mesh topology
C
Correct answer
Explanation
This option is correct as in tree topology, there are two hubs; one is primary and the other is secondary.
-
Tree topology
-
Mesh topology
-
Bus topology
-
Star topology
-
Ring topology
C
Correct answer
Explanation
This option is correct as in this topology, there is a single communication channel that is shared by all the systems in the network.
-
802.5
-
802.4
-
802.11
-
802.6
-
802.3
C
Correct answer
Explanation
This option is correct as 802.11 is IEEE standard given for W-LAN (wireless LAN).
-
10 base T
-
10 base 5
-
10 base 2
-
10 base F
-
RG-6
B
Correct answer
Explanation
This option is correct as 10 base 5 is the name given for thicknet.
-
Star topology
-
Bus topology
-
Ring topology
-
Mesh topology
-
Partial mesh topology
A
Correct answer
Explanation
This option is correct as in star topology, nodes are not directly connected to each other. They are connected through central controller.
-
802.4
-
802.3
-
802.5
-
802.11
-
802.6
A
Correct answer
Explanation
This option is correct as 802.4 is the name given for token bus.
-
It combines the hardware and software network resources and network functionality single network.
-
It provides customization of Access.
-
It provides consolidation among networks.
-
All of the above
-
Both (1) and (3)
D
Correct answer
Explanation
All are the correct statements about Network Virtualization.
-
Ring topology
-
Bus topology
-
Tree topology
-
Star topology
-
None of these
A
Correct answer
Explanation
In ring topology, all of the nodes are connected in a closed loop. Messages travel around the ring.
-
These have low cost.
-
Twisted pairs can be used for transmitting either analog or digital signals.
-
Twisted pairs have poor delay characteristics.
-
None of the above
-
Both (1) and (3)
D
Correct answer
Explanation
All are the characteristics of twisted pair cable.
-
This technique is called store and forward network technique.
-
In this technique, no physical path establishes between the sender and the receiver.
-
Message switching is useless for high data traffic.
-
There is a limit to send a block size.
-
Both (3) and (4)
D
Correct answer
Explanation
Message switching technique has no limit for block of data.
