Description

First, this course will teach you about the OSI reference model and examine protocols like HTTP, TCP/IP, and ATM. It will also cover the characteristics of circuit-switched and packet-switched networks as well as connectionless and connection-oriented modes in packet-switched networks. You will learn about the role played by primitives in the OSI reference model as well as how ‘vertical’ and ‘horizontal’ communication takes place in this type of reference model.

Next, you will cover the subject of Transmission Control Protocol (TCP), Hypertext Transfer Protocol (HTTP), and Asynchronous Transfer Mode (ATM). You will learn how application software interacts with the TCP/IP protocol software, how to find the network and host addresses from IPv4 addresses, and how label switching can support IP over ATM. You will also study digital network security, threats to digital networks, and authentication and access control in digital networks.

This Digital Communication Networks online course will be of interest to professionals who work in information technology, network design, and network management industry. It will also be valuable to students who would like to have a greater understanding of what's behind a digital communication network program and how it functions. So, check out the course now, dig deeper on digital communication networks, and give your career development a boost today.
