Topologies
Question 1 |
The network topology with highest reliability is -------------
Mesh | |
Bus | |
Star | |
Ring |
Question 1 Explanation:
The topology with highest reliability is mesh topology. ... It is a topology commonly used for wireless network. Mesh topology can handle high amounts of traffic, because multiple devices can transmit data simultaneously. A failure of one device does not cause a break in the network or transmission of data.
Question 2 |
Which topology requires a central controller or hub?
Mesh | |
Star | |
Bus | |
Ring |
Question 2 Explanation:
A star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, only one node will be brought down.
Question 3 |
FDDI is a
Ring network | |
Star network | |
Mesh network | |
Bus based network |
Question 3 Explanation:
Fiber Distributed Data Interface (FDDI) uses fiber-optic cable and is wired in a ring topology and Fiber Distributed Data Interface (FDDI) uses token passing as its media-access method and can operate at high speeds.
Question 4 |
In a fully-connected mesh network with 10 computers, total ______ number of cables are required and ______ number of ports are required for each device.
40,9 | |
45,10 | |
45,9 | |
50,10 |
Question 4 Explanation:
Fully connected mesh network, it means it is complete graph. We have standard formula to find total number of cables.
Here, n=10(total number of computers)
= n(n-1) / 2
= 10(9) / 2
= 45
→ To accommodate that many links, every device on the network must have n-1 input/output(I/O) ports
n=10(total number of computers)
= n-1 ports
= 10-1
= 9
Here, n=10(total number of computers)
= n(n-1) / 2
= 10(9) / 2
= 45
→ To accommodate that many links, every device on the network must have n-1 input/output(I/O) ports
