    • Module 1: Overview of networking Page

      Module overview

      We live in an increasingly connected world, and effective communication is becoming more important. To maintain and improve connections, the basic building blocks of networked systems must be efficient and reliable.


      In this module, you’ll learn about the fundamentals that help enable smooth, reliable communication within the digital world. We’ll examine the building blocks of these networks: network protocols, security zones, firewalls, remote access, and VPNs. You’ll also learn how to combine these building blocks to create intranets and extranets, and you’ll learn how to join devices to the internet.

      Objectives

      After completing this module, you will be able to: 

      • Describe networking protocols. 
      • Define the internet, an intranet, and an extranet. 
      • Explain how firewalls work and define security zones. 
      • Understand how to implement VPNs.

    • Module 2: Local area networks and wide area networks Page

      Module overview

      Historically, the earliest networked systems spanned only single offices. They connected a small number of personal computers for the primary purpose of facilitating access to shared resources such as files and printers.


      As the usefulness of personal computer networks became more apparent, the need arose to extend those networks. Initially, this was to overcome distance and signaling limitations that some of the networking components imposed. Later, it was to extend networks across sites, countries/regions, and eventually continents.

      Throughout this period, several networking standards were devised. The various standards implemented a variety of different structures and access methods to link devices over local and wide areas.


      In this module, you’ll learn about local area networking and wide area networking, and you’ll discover the various network topologies and access methods you use to create them.

      Objectives

      After completing this module, you will be able to: 

      • Describe LANs. 
      • Describe WANs. 
      • Identify and explain various network topologies and access methods.

    • Module 3: Media types Page

      Module overview

      To connect network devices together, you must implement either wired media types, a wireless network infrastructure, or both. In this module, we’ll examine the different media types, their susceptibility to interference, and common wireless standards.

      Objectives

      After completing this module, you will be able to: 

      • Describe wired media types. 
      • Explain how to implement a wireless network

    • Module 4: Extending your network Page

      Module overview

      In this module, we’ll examine the technologies that enable you to extend your network. Precisely what technology you use will depend on how far and in what way you want to extend it. For example, some network topologies have imposed limits on the number of devices that can be connected to a single wiring concentrator. Others impose constraints on the distances over which you can reliably transmit data between networked nodes. Essentially, you can extend your network in two ways: by using network switches, or by using routers and selecting an appropriate routing protocol.

      Objectives

      After completing this module, you will be able to: 

      • Describe network switches. 
      • Explain routing. 
      • Describe common routing protocols. 
      • Explain how to implement routing in Windows Server.

    • Module 5: Implementing IP Page

      Module overview

      Earlier in this course, we examined the TCP/IP stack, which Figure 1 depicts. Now it’s time to zoom in and talk a bit more about the IP layer. You might remember that IPv4 and IPv6 operate at the Internet layer of the TCP/IP protocol stack (the network layer of the Open Systems Interconnection (OSI) model). This layer is responsible for delivering packets of information between hosts that might (or might not) be in different subnets. And, of course, we’re going to talk about subnets in this module as well.

      Devices attached to an IP network are assigned a logical network address—an Internet Protocol version 4 (IPv4) or Internet Protocol version 6 (IPv6) address. This unique address ensures that other devices can communicate with the device. In this module, we’ll examine both IPv4 and IPv6 and learn about the two addressing schemes used by these protocols. A heads up: there’s a bit of math in the following pages, so you might want to go and turn on the coffee machine now. Again, Figure 1 depicts a TCP/IP stack:


      Objectives

      After completing this module, you will be able to: 

      • Implement IPv4. 
      • Implement IPv4 subnets. 
      • Implement IPv6.

    • Module 6: Name resolution Page

      Module overview

      For most of us, it’s probably been a long time since we last entered a phone number into our mobile device before we called home. Instead, we just use a contact name that automatically references a number. It’s the same with networking; we use computer names rather than logical numbering systems, like IPv4 or IPv6 addresses, to connect a web browser to a web server.

      In this module, we’ll examine name resolution, the process that resolves a name to the appropriate IPv4 or IPv6 address. As we’ll discover, there are several ways in which computers can resolve names, and we’ll learn more about at each of them.

      Objectives

      After completing this module, you will be able to: 

      • Identify the main methods of name resolution. 
      • Describe how to resolve host names with Domain Name System (DNS). 
      • Describe how to resolve network basic input/output system (NetBIOS) names.

    • Module 7: Network services Page

      Module overview

      So far, we’ve learned about the technologies and tools involved in planning, deploying, and configuring the networking components necessary to provide the network infrastructure fundamentals for an organization. In this module, we’ll explore adding services that enable you to more easily configure computer devices with the necessary network settings. We’ll also examine how to facilitate remote access for users who want to access organizational resources from somewhere other than the corporate network.

      Objectives

      After completing this module, you’ll be able to: 

      • Describe how to implement DHCP.

    • Module 8: Troubleshooting networks in Windows Page

      Module overview

      Configuring network settings is a common administrative task, and for many organizations, it accounts for a significant percentage of overall administrative effort. The Windows 10 operating system includes several tools that you can use to set up and troubleshoot both wired and wireless network connections more efficiently. To support an organization’s network infrastructure, it’s important that you understand how to use these tools to configure and troubleshoot network connections.
