Start Course
Description

In this course, Introduction to Networking for Cisco CCNA, you will examine how basic human communication, like talking in person or on the phone, contains the same fundamental concepts used in moving data across a network. First, you will learn how to examine communication, and determine how to dissect it into components so it can be individually categorized and described. Next, you will learn how to break down communication into components, which will be of great benefit when understanding data networking, as there are many simple protocols which interact in complex ways. To accomplish this you will learn the TCP/IP and OSI models of networking, encapsulation, addressing, as well as what is called "chunks of information" at different points in the communication process. Finally you'll learn about the history and the birth of high speed data communications. By the end of this course, you'll know the OSI Model, TCP/IP Model, and you'll have an understanding of what encapsulation is as it relates to data networking.

Start Course
Description

As early as 1985, engineers knew there would be a shortage of IPv4 addresses before the end of the century. Over the next decade, engineers found a very clever solution to the problem, however it created a complex address. In this course, Network Layer Addressing and Subnetting, you will dive into extreme detail about the structure of an IPv4 address and its subnet mask counterpart. To do this, understanding binary numbers becomes very important. First, you will learn to describe how binary numbers work, how to convert from decimal to binary and back again, as well as see how hexadecimal easily integrates into binary. This may sound daunting, however, we keep the content simple and easy to follow, so it is not overwhelming. Next, you will explore how to understand binary and the structure of an IPv4 address, examining how to break a single IPv4 network into multiple IPv4 networks, understand the definition of a network address, broadcast address, and a host address. You will the examine how to calculate networks more efficiently using Variable Length Subnet Masking(VLSM), and to wrap up IPv4 addressing, we will take a simple IPv4 network, break it into 2 networks, and then observe its behavior across a router. Finally, you will wrap up IPv4, and move into IPv6, and understand the nuances of this new and obscure looking address. We keep it as simple as possible, so you understand the structure and operation of the IP address, without getting bogged down in nuanced details, infrequently used in IPv6. By the end of this course, you will have a much better grasp on IPv4 and a new understanding on the growing IPv6.
