1. Which of the following best defines a communication system?
A. A method to store data securely
B. A network of devices that exchange information
C. A program that converts data into graphics
D. A hardware component that processes signals
Answer: B
Rationale: A communication system is a network of interconnected
devices or components designed to transmit and receive information.
2. The primary function of a transmitter in a communication system is to:
A. Receive data from users
B. Convert information into signals for transmission
C. Filter out noise from incoming messages
D. Store data temporarily
Answer: B
Rationale: The transmitter converts information into signals suitable for
transmission over a communication medium.
3. In radio communication, the antenna acts as:
A. A data processor
B. A signal amplifier
C. A transducer
, D. A storage device
Answer: C
Rationale: An antenna is a transducer that converts electrical signals into
electromagnetic waves and vice versa.
4. Which component receives the transmitted signal in a basic
communication system?
A. Transmitter
B. Receiver
C. Antenna
D. Amplifier
Answer: B
Rationale: The receiver captures the transmitted signal and converts it
back into usable information.
5. What type of signal varies continuously over time?
A. Digital signal
B. Analog signal
C. Binary signal
D. Encoded signal
Answer: B
Rationale: Analog signals are continuous and represent information by
varying amplitude or frequency over time.
6. In a digital communication system, data is represented by:
A. Waves
B. Frequencies
C. Bits (0s and 1s)
D. Amplitude shifts
Answer: C
Rationale: Digital communication represents data in binary form—0s and
1s.
7. The main advantage of digital communication over analog
communication is:
A. Simplicity
B. Better error detection and correction
, C. Continuous transmission
D. Less bandwidth usage
Answer: B
Rationale: Digital communication allows easier error detection and
correction, improving reliability.
8. Which of the following is a type of noise in communication systems?
A. Channel noise
B. Data noise
C. White noise
D. Optical noise
Answer: C
Rationale: White noise refers to random electrical noise that affects
signal clarity in a communication system.
9. Bandwidth refers to:
A. The time a signal takes to transmit
B. The range of frequencies used for transmission
C. The power of a signal
D. The distance a signal travels
Answer: B
Rationale: Bandwidth is the difference between the highest and lowest
frequencies used to carry a signal.
10.Modulation is used in communication systems to:
A. Reduce noise
B. Adjust signal power
C. Transmit signals over long distances
D. Filter out interference
Answer: C
Rationale: Modulation modifies a carrier signal to allow transmission of
information efficiently over long distances.
11.AM stands for:
A. Amplitude Modification
B. Amplitude Modulation
C. Analog Modulation
