A substitution cipher replaces one symbol with...
- A.
Parties
- B.
Single party
- C.
Others
- D.
Keys
Correct Answer
C. OthersExplanation
A substitution cipher replaces one symbol with others. In this type of cipher, each symbol in the plaintext is replaced by a different symbol or character in the ciphertext. This is done to encrypt the message and make it more difficult for unauthorized individuals to understand the original content. The symbols used for substitution can vary depending on the specific cipher being used.Rate this question:

What is known as the combination of two or more networks?
- A.
Inter-network
- B.
The Internet
- C.
Intra-network
- D.
WAN
Correct Answer
A. Inter-networkExplanation
The term "inter-network" refers to the combination of two or more networks. It suggests the connection between different networks to create a larger network infrastructure. This can involve linking local area networks (LANs) or wide area networks (WANs) together, allowing for communication and data sharing between the connected networks. The Internet, on the other hand, refers to the global network of interconnected networks. Intra-network refers to the network within a single organization or entity. WAN stands for wide area network, which is a network that spans a large geographical area, such as multiple cities or countries.Rate this question:

Which of these is an inverse of Period?
- A.
Frequency
- B.
Phase
- C.
Amplitude
- D.
Signal
Correct Answer
A. FrequencyExplanation
The inverse of period is frequency. Period refers to the time it takes for one complete cycle of a repeating event, while frequency refers to the number of cycles that occur in a given time period. Since frequency is the reciprocal of period, it can be considered as the inverse of period.Rate this question:

When retransmitting frame in the Field retry, the value must be set to...
- A.
Infinity
- B.
0
- C.
1
- D.
-1
Correct Answer
C. 1Explanation
When retransmitting a frame in the Field retry, the value must be set to 1. This suggests that when there is a need to resend a frame in the Field retry, the value should be set to 1. This value indicates that the frame is being resent once, allowing for a chance to successfully transmit the frame. The other options, such as Infinity, 0, and -1, are not suitable values for this scenario.Rate this question:

Piggybacking protocol is a technique used for...
- A.
NAKs
- B.
ACKs
- C.
A and B
- D.
None of the above
Correct Answer
C. A and BExplanation
The piggybacking protocol is a technique used for both NAKs (Negative Acknowledgments) and ACKs (Acknowledgments). This protocol allows the receiver to send both the acknowledgment for the received data and any negative acknowledgment for the missing or corrupted data in the same packet. By combining these two types of acknowledgments in a single packet, the piggybacking protocol improves the efficiency of the communication process and reduces the overhead of sending separate packets for each type of acknowledgment.Rate this question:

The data rate of Teledesic System can be up to...
- A.
155 Mbps
- B.
145 Mbps
- C.
150 Mbps
- D.
135 Mbps
Correct Answer
A. 155 MbpsExplanation
The correct answer is 155 Mbps. The Teledesic System has a data rate that can reach up to 155 Mbps.Rate this question:

What is the address space of a system with 8-bit address?
- A.
32
- B.
65535
- C.
720
- D.
256
Correct Answer
D. 256Explanation
The address space of a system is determined by the number of unique memory locations that can be addressed. In this case, the system has an 8-bit address, which means that it can address 2^8 = 256 unique memory locations. Therefore, the correct answer is 256.Rate this question:

Which of these layers directly controls the transmission media?
- A.
Network layer
- B.
Data link layer
- C.
Physical layer
- D.
Session layer
Correct Answer
C. pHysical layerExplanation
The physical layer directly controls the transmission media. This layer is responsible for transmitting raw bits over a physical medium, such as cables or wireless signals. It defines the electrical, mechanical, and procedural specifications for transmitting data, including the type of cable to be used, the voltage levels, and the encoding scheme. The physical layer handles tasks such as signal modulation, error detection, and media access control. It is the lowest layer in the OSI model and establishes the physical connection between devices for data transmission.Rate this question:

Which of these is an example of a non-periodic composite signal?
- A.
Black and white TV
- B.
Colored TV
- C.
Transistor Radio
- D.
DVD
Correct Answer
A. Black and white TVExplanation
A non-periodic composite signal refers to a signal that does not repeat itself in a regular pattern over time. Black and white TV is an example of a non-periodic composite signal because the video signal it carries does not have a repeating pattern. In contrast, colored TV, transistor radio, and DVD all involve signals that have a periodic nature or repeating patterns, making them periodic composite signals.Rate this question:
