This course is designed to provide a full overview of computer networking. We’ll cover everything from the fundamentals of modern networking technologies and protocols to an overview of the cloud to practical applications and network troubleshooting.

By the end of this course, you’ll be able to: ● describe computer networks in terms of a five-layer model ● understand all of the standard protocols involved with TCP/IP communications ● grasp powerful network troubleshooting tools and techniques ● learn network services like DNS and DHCP that help make computer networks run ● understand cloud computing, everything as a service, and cloud storage

Welcome to the Networking course of the IT Support Professional Certificate! In the first module of this course, we will cover the basics of computer networking. We will learn about the TCP/IP and OSI networking models and how the network layers work together. We'll also cover the basics of networking devices such as cables, hubs and switches, routers, servers and clients. We'll also explore the physical layer and data link layer of our networking model in more detail. By the end of this module, you will know how all the different layers of the network model fit together to create a network.

A lot of information, but i feel like i fully understand core networking concepts. A lot of this info has helped me comprehend what will be required for me when I take my Network + certification exam.

已于 Nov 26, 2020审阅

The course gives a good overview over the computer networking, not going very deep. Quizzes are very useful for learning process. Graphical materials that given during video lessons could be improved.

已于 Apr 15, 2018审阅

I learned a lot more than I thought I would. Some of it I knew, like a few of the terms but didn't know how it connected with the entire web of Networking. Now I have a must better understanding.

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

When you enroll in the course, you get access to all of the courses in the Certificate, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
