• Unit 1: Networking Fundamentals

    When you think of networking, what is the first word that comes to mind? If you answered "Internet," you are correct. The Internet is an example of a massive computer network. Computer networks make it possible for one device to communicate with another device. Another example of a computer network is the local area network, or LAN. If you can access all of the desktops, laptops, wireless devices, and printers in your workplace, college, or home, you have a LAN.

    This unit will introduce the basic concept of a computer network and arm you with the tools you will need to work through the more technical aspects of this course. You will take a look at the different types of networks that exist, with the primary focus on the LAN. The unit continues with an introduction to the concept of layers, which is central to understanding how computer networks operate. You will also become familiar with Request for Comments (RFC) documents, which are standards that define all of the Internet protocols. RFCs are created by The Internet Engineering Task Force (IETF).

    The concepts presented in this course will provide you with the background information needed to develop network applications, take a network certification course, or communicate with other networks neighboring your LAN.

    Completing this unit should take you approximately 4 hours.
