Which network topology requires terminators?
- A.
Bus Network
- B.
Star Network
- C.
Ring Network
Correct Answer
A. Bus NetworkExplanation
Bus network topology requires terminators because it is a linear network where all devices are connected to a single cable. Without terminators, the signals would bounce back and forth on the cable, causing interference and signal degradation. Terminators are used to absorb these signals and prevent them from reflecting back, ensuring proper communication within the network.Rate this question:

- 9.
Which Network Topology is fastest?
- A.
Bus Network
- B.
Ring Network
- C.
Star Network
Correct Answer
C. Star NetworkExplanation
The star network topology is considered the fastest because it allows for direct communication between devices and the central hub (usually a switch). In a star network, each device has its own dedicated connection to the central hub, which eliminates the need for data to pass through multiple devices before reaching its destination. This results in faster data transmission and reduced network congestion compared to bus and ring network topologies, where data must pass through all devices in the network.Rate this question:

The bridge is a networking device used at the network layer of the OSI reference model.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Bridges are actually networking devices used at the data link layer of the OSI reference model, not at the network layer. The network layer is responsible for routing and addressing, while the data link layer handles the physical transmission of data between adjacent network nodes. Bridges operate by examining the MAC addresses of incoming data packets and forwarding them to the appropriate destination based on that information. Therefore, the correct answer is false.Rate this question:

FM radio signal is an example of ful-duplex communication.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is incorrect. FM radio signal is an example of half-duplex communication, not full-duplex. In half-duplex communication, data can be transmitted in both directions, but not at the same time. In the case of FM radio, the radio station transmits the signal, and the receiver (radio) picks up the signal. However, the receiver cannot transmit back to the radio station simultaneously. Therefore, the correct answer is False.Rate this question:

IP addresses are same as MAC addresses.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement "IP addresses are same as MAC addresses" is false. IP addresses and MAC addresses are two different types of addresses used in computer networks. An IP address is a numerical label assigned to each device connected to a network, while a MAC address is a unique identifier assigned to the network interface card of a device. IP addresses are used for routing and identifying devices on a network, while MAC addresses are used for identifying devices on a local area network.Rate this question:
