Networking is valuable for sharing hardware, accessing the internet, data sharing, connectivity and communication and entertainment.

Networking is the method by which two or more computing devices can be linked together for the purpose of sharing data. Networks are developed by mixing computer hardware and computer software. Networking can help you to reorganize the office, share music files and printers. The Networking course will provide you tips and give a comprehensive understanding of the tools and techniques which will get you started with setting up a network. There are two kinds of network available; wired networks which use Ethernet (CAT-5) cables to connect to networked components and wireless networks which use Wi-Fi which is a wireless communication standard.


The ExpertRating Networking Certification will help you easily set up a network at home, in the office or in schools.

ExpertRating Online Computer Networking Course-II Coverage (6 weeks program)  

Week One

Wednesday - Lesson 01

In this first lesson, you'll learn about the concept of a network stack. After a succinct review of essential network and networking terms, this lesson will compare the theoretical structure of a network stack—commonly called the OSI model—to real-world networking. This lesson will then trace how data travels through the computer for transmission on the network.

Friday - Lesson 02

This lesson will pick up right where the last lesson left off when it begins its 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.

Week Two

Wednesday - Lesson 03

This 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 this lesson will discuss why routers have their own special languages, called routing protocols.

Friday - Lesson 04

In this lesson 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).

Week Three

Wednesday - Lesson 05-

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!

Friday - Lesson 06

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.

Week Four

Wednesday - Lesson 07

This lesson will 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.

Friday - Lesson 08

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 this 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.

Week Five

Wednesday - Lesson 09

The Internet, and almost every other network now-a-days, uses Domain Name System (DNS) to translate names people 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.

Friday - Lesson 10

This lesson will expand on its discussion of DNS. 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 that too you'll learn about in this lesson. By the end of this lesson, it'll be clear just how important DNS is to your daily lives!

Week Six

Wednesday - Lesson 11

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 those will be investigated in this lesson.

Friday - Lesson 12

Have you ever wondered about the difference between a desktop computer and a server? There are important differences. This final lesson will 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.
