Data Communication Notes for CSE Students | DC Lecture Notes PDF Free Download

Data Communication Notes: Data Communication course provides the theoretical and practical knowledge of Data Communication. It educates the students about the basic concepts of data and network communication used in networking technologies. Students get the opportunity to understand the fundamentals of modern data and network communication. There are different courses available on Data Communication. Sometimes, Data Communication is also taught in the bachelor’s programme. However, study materials and notes are essential for this course. In this article, you will get complete details about the reference books, study materials, and Lecture notes available for Data Communication.

Introduction to Data Communication

Data Communication is the process in which data gets exchanged between a source and a receiver through transmission media. If the communicating devices are in a similar geographical area, it is called local data communication. The device that transmits data is called the source. The receiver receives the transmitted data. Data Communication focuses on data transfer and maintenance throughout the transmission process. Data exists in various forms such as text, numbers, and bytes. This article will help you to learn more about the subject in detail before you choose to start studying Data Communication.
