Course Syllabus:
Lesson 1 Syllabus	In our first lesson, you'll learn about the concept of a network stack. After a succinct review of essential network and networking terms, we'll compare the theoretical structure of a network stack—commonly called the OSI model—to real-world networking. We'll then trace how data travels through the computer for transmission on the network.
Lesson 2 Syllabus	We'll pick up right where the last lesson left off today when we begin our discussion on how a unit of computer data—called a packet—gets from one computer to another. You'll learn all about how packets are formed, how packets are sometimes chopped then reassembled to go across WAN links, and how the receiving computer handles packets upon arrival. You'll also learn why the network's most important device is the router.
Lesson 2 Objective	Learn the defined concepts and terms that will be used throughout the course, and understand the network stack model.
Lesson 3 Syllabus	Today's lesson is dedicated to helping you understand how routers operate. You'll learn all about how routers create a virtual map of the entire Internet. You'll also see how routers connect to different network types—an Ethernet segment and an ATM link, for example—transmit data across those different mediums. Then we'll discuss why routers have their own special languages, called routing protocols.
Lesson 3 Objective	Understand how a packet traverses a network, from initial placement onto the wire to crossing WAN links.
Lesson 4 Syllabus	Today you'll learn the language of routers: routing protocols. You'll learn why some routing protocols are appropriate for smaller networks, and why very large networks require specialized routing protocols. You'll also learn about the two most revealing measurements of a router's capability: latency and packets per second (pps).
Lesson 4 Objective	Learn extensive routing terminology terms and concepts, and understand operational details of routing.
Lesson 5 Syllabus	You've heard of TCP/IP, but its details may seem mysterious. After you complete this lesson, those mysteries will be banished forever! You'll learn about IP addressing, the four primary IP address classes, and all about the various protocols that come packaged within TCP/IP. Prepare to demystify TCP/IP!
Lesson 5 Objective	Learn the various types of routing protocols used, and be capable of differentiating between them. Understand the strengths and weaknesses of each.
Lesson 6 Syllabus	Security is on everyone's mind these days, so in this lesson, you'll learn the fundamentals of how computers enforce security. You'll learn what a security descriptor is and how it can allow some people to only read a document, while others can delete or modify the document as much as they like. You'll also learn the difference between a security implementation and security protocols. Finally, you'll find out how security operates in a Windows environment, including exactly what happens during log on, authentication, and authorization.
Lesson 6 Objective	Obtain an in-depth understanding of IP addressing, address classes, and the functionality of other protocols in the TCP/IP protocol suite.
Lesson 7 Syllabus	In today's lesson, we'll explore encryption, a method used to secure data for transmission over the Internet. You'll learn about various encryption schemes, and you'll get firsthand knowledge of how a chunk of data gets encrypted, how it gets decrypted on the receiving end, and how this process can be secure. You'll also learn how Secure Sockets Layer (SSL) makes it safe for you to order merchandise online, and how SSL ensures that your connection to the seller's Web site is secure.
Lesson 7 Objective	Learn the fundamentals of security in a networked environment, and understand the trio of events that preserve security.
Lesson 8 Syllabus	The Internet is a great public network, but what if you need it for private communication? For example, what if a salesman needs to make a private connection to her company's network to check on special bulk pricing? In today's lesson, you'll learn how you can create a virtual private network out of your Internet connection. You'll get a hands-on view of how these private connections are made, and why they're so useful.
Lesson 8 Objective	Understand encryption and how it can be used in public or private networks to secure data and to reliably authenticate users.
Lesson 9 Syllabus	The Internet, and almost every other network today, uses Domain Name System (DNS) to translate names we understand (like www addresses) into IP addresses that computers can use. It's important to understand how this system works, so in this chapter you'll learn details about how DNS operates. You'll learn how resource records are the building blocks of DNS, and how DNS scales to the entire Internet by being broken into zones.
Lesson 9 Objective	Learn about virtual private networks (VPNs), including the reason they were invented and the way they operate.
Lesson 10 Syllabus	We'll expand on our discussion of DNS in this lesson. Here you'll learn about the most important types of resource records, including A records, SOA records, and others. You'll also learn about the two types of DNS queries: recursive and iterative. There are many other resource record types, and you'll learn about those today, too. By the end of this lesson, it'll be clear just how important DNS is to our daily lives!
Lesson 10 Objective	Understand fundamental and operational aspects of the Domain Name System (DNS), providing a basis for the subsequent lesson.
Lesson 11 Syllabus	In this lesson, you'll learn how Internet Servers operate, including how a Web page is requested and transmitted to your computer, then displayed on your screen. You'll also learn about the two primary Web protocols—HTTP and HTML. There are other Internet-based services, such as e-mail servers, news servers, and instant messaging, and we'll investigate those in this lesson, too.
Lesson 11 Objective	Building upon the previous lesson, understand the basic units of DNS name resolution and how DNS resolves names.
Lesson 12 Syllabus	Have you ever wondered about the difference between a desktop computer and a server? There are important differences. In our final lesson, we'll go over the differences between server-class operating systems, server-class computers, and talk in-depth about the various hardware components that comprise a true server-class computer. Understanding why a desktop computer shouldn't be used as a departmental server is important! In this lesson, you'll learn why.
Lesson 12 Objective	Learn how Web surfing occurs, including languages and protocols that enable it, and how the Internet provides its rich, interactive, and commercial content.
