Data Communications Quiz

What are the types of communication?

• Simplex and Duplex

• Analog and Digital Signal

• Half Duplex and Full Duplex

• Parallel and Serial Transmission

Answer explanation

The correct types of communication are Simplex and Duplex, where Simplex allows communication in one direction only, and Duplex allows communication in both directions simultaneously.

Answer explanation

The correct answer is 'Data Communications and Network Classifications' as it covers the evolution of network technology from basic data communications to the classification of different types of networks.

What is the difference between Simplex and Full Duplex?

• Simplex allows data to flow in both directions simultaneously, Full Duplex allows data to flow in both directions simultaneously

• Simplex allows data to flow in one direction at a time, Full Duplex allows data to flow in one direction at a time

• Simplex allows data to flow in one direction only, Full Duplex allows data to flow in both directions simultaneously

• Simplex allows data to flow in both directions simultaneously, Full Duplex allows data to flow in one direction at a time

Answer explanation

Simplex allows data to flow in one direction only, Full Duplex allows data to flow in both directions simultaneously

What are the characteristics of Analog Signal?

• Continuous and smooth signal

• Discrete and step-wise signal

• Single direction flow

• Bi-directional flow

Answer explanation

Analog signals are characterized by being continuous and smooth, unlike digital signals which are discrete and step-wise.

How does Parallel Transmission differ from Serial Transmission?

• Parallel Transmission sends multiple bits simultaneously, Serial Transmission sends one bit at a time

• Parallel Transmission sends one bit at a time, Serial Transmission sends multiple bits simultaneously

• Parallel Transmission is slower than Serial Transmission

• Serial Transmission is slower than Parallel Transmission

Answer explanation

Parallel Transmission sends multiple bits simultaneously, Serial Transmission sends one bit at a time

What is the purpose of Network Classifications?

• To categorize networks based on their size and functionality

• To determine the speed of data transmission

• To identify the type of communication used

• To differentiate between analog and digital signals

Answer explanation

To categorize networks based on their size and functionality

What is the significance of Analog Signal in data transmission?

• Continuous and smooth signal

• Discrete and step-wise signal

• Single direction flow

• Bi-directional flow

Answer explanation

Analog signals are continuous and smooth, allowing for the representation of data in a non-discrete manner, making them significant in data transmission.
