1. The physical or logical arrangement of the network is called________?

A topology

B routing

C networking

D None of the above

A
A network topology describes the arrangement of systems on a network. It defines how the computers, or nodes, on the network are connected to each other. Some common network topologies include star, ring, bus, and other configurations.

 

 

2. In _______ topology, there is a HUB.

A star

B mesh

C ring

D bus
 

 
A
A star topology is a network topology in which each network element is associated with a central node (often called a hub or switch).

 

 

3. _______ topology, requires a multipoint connection

A star

B mesh

C ring

D bus

D
The multipoint connection is used in BUS topology. All devices are connected to a single transmission medium, which serves as the backbone of the connection.

 

 

4. The communication system that covers a state, country or the whole world is called a _______ network?

A LAN

B WAN

C MAN

D None of the above

B
The Wide Area Network (WAN) covers the entire global network.

 

 

5. The communication system in a building or campus is ___?

A LAN

B WAN

C MAN

D None of the above

A

 

 
 

6. The WAN means _______?

A World area network

B Wide area network

C Web area network

D None of the above

B

 

 

7. In TDM, the time slots are divided into _______?

A Seconds

B Frames

C Packets

D None of the above

B
A TDM (time division multiplexing) circuit operates with a much higher signal bandwidth, which allows the bandwidth to be divided into time frames (time slices) for each voice signal multiplexed on the line by the transmitter.

 

 

8. Which multiplexing technique moves each signal to a different carrier frequency?

A FDM

B TDM

C FDM and TDM

D None of the above

A
FDM stands for Frequency Division Multiplexing.

 

 
 

9. The sharing of a medium by two or more devices is called _________?

A Full duplex

B Multiplexing

C Both A and B are true.

D None of the above

B
In a multiplexed system, the link is divided into channels, n lines share the bandwidth of a single line.

 

 

10. Multiplexing is used in the _______?

A packet switching

B circuit switching

C data switching

D None of the above

B
