, PART ONE: INTRODUCTION
Chapter 1: Introduction to Data Communications
1. What is the primary function of data communication?
o A) Data storage
o B) Data processing
o C) Data transmission
o D) Data retrieval
Answer: C) Data transmission
Explanation: Data communication focuses on the transmission of data between devices, enabling
information exchange.
2. Which of the following is NOT a component of data communication systems?
o A) Message
o B) Sender
o C) Receiver
o D) Processor
Answer: D) Processor
Explanation: The main components include sender, receiver, message, medium, and protocol.
Processor is part of computing systems, not directly a data communication component.
3. Which layer is responsible for data encryption and decryption in data communication?
o A) Physical layer
o B) Data link layer
o C) Application layer
o D) Presentation layer
Answer: D) Presentation layer
Explanation: The presentation layer handles data translation, encryption, and decryption.
4. What is bandwidth in the context of data communications?
o A) The physical distance between sender and receiver
o B) The capacity of a communication channel
o C) The speed at which data is processed
o D) The type of encoding used
Answer: B) The capacity of a communication channel
Explanation: Bandwidth refers to the maximum rate of data transfer across a given path.
5. Which medium is considered a guided transmission medium?
o A) Radio waves
o B) Microwave
o C) Fiber optic cables
o D) Satellite
