The transfer of digital signals between computers serving as the transmitter and receiver on both ends of a data communication session is called data communication. This course begins by examining the fundamentals of data communication. We explain standards organisations for data communications and identify the most important aspects of a layered architecture for data communication. We will help you answer questions like What is the OSI Model? and 'What are layers and interfaces?.This course describes how data communication circuits work. We outline the measuring capacity of communication media and explore the crucial processes of serial and parallel data transmission including data communication circuit arrangements. The course then delves into data communication networks. This section researches the benefits of peer-to-peer NOSs over client-server NOSs and the significance of network topology.This course provides the concepts you need to understand data communication and the layered architecture for data communication. You can use these ideas to find a job or use them in the position you already have. We cover topics that can help your career such as amplitude modulation and converting data into signals. Sign up today to confidently use these concepts in your work or to help others understand them.
