Commercial transactions

Academic and research networking

Entertainment distribution

Military communication

5. What major development marked the transition from ARPANET to the modern Internet?

Introduction of smartphones

Launch of commercial ISPs (Internet Service Providers)

Creation of the World Wide Web (WWW)

Implementation of fiber-optic cables

6. Define the concept of communication in the context of data communication.

The exchange of information between computers using radio waves

The process of transferring data between devices through a network

The creation of data through programming languages

The storage of data in a centralized database

7. What are the main components of data communication?

Transmitter, Receiver, Data

CPU, RAM, Hard Drive

Input, Output, Processing

Switch, Router, Hub

8. In data communication, what is a protocol?

A set of rules for formatting data

A physical device that connects networks

A type of computer programming language

A measurement of data transfer speed

9. What is the purpose of measuring the capacity of communication media in terms of bandwidth?

To determine the physical size of the communication medium

To measure the frequency range of the communication medium

To assess the cost of the communication medium

To evaluate the security features of the communication medium

10. What is the relationship between bandwidth and data transfer rate?

They are unrelated concepts

Bandwidth is a measure of speed, while data transfer rate is a measure of capacity

They are synonymous terms

Bandwidth and data transfer rate are the same thing

11. What is an IP address used for in computer networks?

To identify the type of data being transmitted

To identify the location of a device on the network

To encrypt data for secure transmission

To control the flow of data packets

12. Explain the concept of packet switching in networking.

Dedicated communication path for each conversation

Breaking data into packets for transmission over a network

A technique for assigning IP addresses dynamically

Routing data through multiple servers for redundancy

13. What is the fundamental difference between circuit switching and packet switching?

Circuit switching is faster than packet switching

Packet switching uses dedicated paths, while circuit switching does not

Circuit switching is more efficient for large-scale networks

Packet switching breaks data into packets for transmission

14. How is bandwidth related to the capacity of a communication channel?

Bandwidth is a measure of data transfer rate

Bandwidth is a measure of the physical size of the channel

Bandwidth is unrelated to the capacity of the channel

Bandwidth is a measure of signal strength

15. In the context of networking, what is the role of a router?

To connect devices within the same local network

To transmit data between different networks

To store data temporarily during transmission

To convert analog signals to digital signals
