Whether you’ve been tinkering with IT or are completely new to the field, you’ve come to the right place.
If you’re looking for a job, upon completion of the certificate, you can share your information with top employers, like Bank of America, Walmart, Sprint, GE Digital, PNC Bank, Infosys, TEKsystems, UPMC, and, of course, Google.

Course 2 - The Bits and Bytes of Computer Networking (Module 1 Introduction to Networking)

About the Course
This course is designed to provide a full overview of computer networking. In this course, we’ll cover everything from the fundamentals of modern networking technologies and protocols 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. Except as otherwise noted.

Who is this class for: This program is intended for beginners who are interested in developing the skills necessary to perform entry-level IT support. No pre-requisite knowledge is required. However, if you do have some familiarity with IT, you can skip through any content that you might already know.
Module 2 - The Network Layer

In the second module of this course, we'll explore the network layer in more depth. We'll learn about the IP addressing scheme and how subnetting works. We'll explore how encapsulation works and how protocols such as ARP allow different layers of the network to communicate. We'll also cover the basics of routing, routing protocols, and how the Internet works. By the end of this module, you'll be able to describe the IP addressing scheme, understand how subnetting works, perform binary math to describe subnets, and understand how the Internet works.
