TCP/IP is the globally accepted group of protocols at the core of the Internet and organizational intranets. In this course, you'll start at the beginning and learn about the origins of the protocols that underpin the Internet and enterprise networks. You'll explore each of the layers of the TCP/IP networking model, as well as the concept of peer protocols. You'll also examine the standardization process that is overseen by the Internet Engineering Task Force. Finally, you'll learn about the types of requests for comments that are used by this task force. Depending upon the type of information you have and who is using it, information is stored, transmitted, and displayed in different ways. As a result, different numbering systems are used to represent that information. Understanding these number systems, which can be binary, decimal, or hexadecimal, is an important skill for those who interpret and troubleshoot network systems. In this course, you'll also learn about the four numbering systems used by data systems. You'll also explore positional number system representations, how values are represented using numbering systems, and how to convert values between them. Finally, you'll learn different methods for determining the base of a value when the base is unknown. This course was originally created by Global Knowledge (GK).
