Description

In this quiz, we will be concentrating on communication with respect to machines or computers in general. Communication is a way of transferring or conveying information in an understandable way that can be sent and received. And you will be amazed to know that Studying communication can improve how we see others as communication is the best way we meet others, develop and manage relationships and work effectively with them.

A communication system is a system model that describes communication between two stations, transformer, and receiver.In order for information to pass from source to a destination during communication, it passes through a special route known as a channel. There are two types of communication systems, Line and radio communication systems.These two are based on physical infrastructure. The types according to baseband signals, we have analog and digital communication systems.

On taking the quiz, you will find MCQs with one and only one correct answer, and you have a chance of ¼ to have a pass mark per question. After the quiz, you can find more quizzes by going back to our home website. There are also more Computer Science quizzes.

Good luck!
