A short overview of what will be presented in this course.
Section 1: Lesson One - Network Basics

A brief introduction of what will be covered in this lesson.

Today network structures can range from very simplistic through to something that is very, very complex. Let's take the first steps.
Let's dig a little bit deeper under the surface and have a look at "Why use a network"?
Within networks, there are many services and components that connect it all together.
Within networks, there are many services and components that connect it all together.
Let's demystify some of the jargon that you have to become familiar with, regarding modern networks.

The seven layer OSI model rationalizes how data travels across the network.


Let's take a look at the four layers in the TCP/IP protocol stack.

Learn how the TCP/IP Protocol and the OSI model relate to each other.

Protocols are where we get the magic and the mysticism happening within networks.

On a network, data has to move between computers. We do this using addressing or IP addressing which is referred to as routing.

Section 2: Lesson Two - Elements of a Network
A brief introduction of what will be covered in this lesson.
A Local Area Network, or a LAN, consists of a well-connected group of computers. But how are these connections actually created for us?

What is an internetwork connectivity device?


Every network card in existence has a unique property. This property is a media access code, or MAC address.


For data to be transported across an Ethernet network, it needs to be assembled into an Ethernet frame.

Ethernet cables are used to connect network cards within computers to other network devices.

In this video you will learn about the network operating systems.

A Network Operating System allows us to connect to resources over a network on devices other than computers. Let's now take a look at how we can do that with Windows 7 and Windows XP.

Section 3: Lesson Three - TCP/IP Basics

A brief introduction of what will be covered in this lesson.

Transmission Control Protocol, Internet Protocol or TCP/IP. It's not a single protocol. In fact, it's a suite of protocols that are arranged in a four layer stack.
An IPv4 address has a defined structure. You'll see it broken down into four octets.
IPv4 is a “classful” addressing system and it's broken down into five classes of addresses.

You will learn that some IP addresses are reserved addresses.

Learn how to set an IP address up on a computer system.
Address Resolution Protocol, or ARP, is a broadcast based protocol that is responsible for resolving the IP address of a computer to its physical or MAC address.

How does a computer system access resources on other networks, or indeed, how does a computer system find its way off of one network and to the Internet?


Why break large networks down into smaller subnetworks or subnets?


Computers use binary number format. What does that mean for our IP addresses?


We're running out of IP addresses because the standard classful IP addressing system is wasteful. What should we do?


The available public IPv4 address space is limited and nearly exhausted. So, we need another solution. That solution is IP Version 6, or IPv6.


IPv6 offers sextillions of IP addresses, which is billions of IP addresses per square millimeter of the planet's surface.


When we're working with an IPv6 network, there are three major types of IP addresses that we'll work with.


Within IPv4, you have two transport protocols available.


The Transmission Control Protocol is the TCP element of the TCP/IP protocol suite.


The User Datagram Protocol, or UDP, is the second transport protocol in the TCP/IP Suite.

How can a computer system work out which applications it should be going to?

Section 4: Lesson Four - Commonly Used IP Network Protocols

A brief introduction of what will be covered in this lesson.


The TCP/IP protocol is operating around a four-layer stack. An application layer, a transport layer, an Internet layer and a network interface layer. Learn what sits within these layers.


You know that on an IP network, every machine must have an individual or unique IP address. Now, imagine that this network has got thousands of computers. How does the data find the correct one?


The DHCP lease has an expiry time. So what happens when that lease is approaching its expiration date? What will the client do?

You can switch to an IP address that is obtained automatically using either the GUI or using the command line.
What does DHCP use during the DORA process? The discover, offer, request and acknowledgement steps.

If you've got 500 computers, does that mean that you have to go and buy 500 public IP addresses?

PAT, or Port Address Translation, is a more complex version of NAT, or Network Address Translation.

DNS or the Domain Name System is something that a network simply couldn't exist without today.


DNS Name-Space Syntax is used to give us a fully qualified domain name.


Domain Name System, or DNS, is hosted by a DNS server.

How is it, that our internal computer can actually resolve the name of an Internet-based web server?

When we're working on a computer network, we use the names of those computers to actually establish communication sessions with them.


What happens if we have the IP address of a computer, and we need the name of that computer?

There may be occasions where you need to interact with DNS on the client side, and the best way to do this is using command line utilities.
Learn how to use Telnet and FTP to your advantage.

Telnet is a Terminal Emulation program, which allows you to actually open up a remote sessions on a computer system over the network and work as if you were logged on locally.

FTP is a great quick and clean system for transferring files over a network.

Section 5: Lesson Five - Windows Networking Tools
A brief introduction of what will be covered in this lesson.

A lot of the networking tools that we can work with, within Windows, are actually accessible through the command prompt, or the command-line interface.

Learn how to run Network Shell (netsh) from the command prompt.
Learn how to us ipconfig to view the IP configuration of a system or ping to make sure that another machine is up, available, and responding on the network.

Learn how to use traceroute, or tracert, for troubleshooting.


Address Resolution Protocol is the protocol that's responsible for mapping a computer's IP address to a MAC address.

Use netstat to display the current connections to a computer system, which computers those connections are coming from, which IP addresses they're using, and which ports they're connected to.

Learn how to run NS lookup in interactive mode and non-interactive mode.

Section 6: Lesson Six - Windows Control Panel
A brief introduction of what will be covered in this lesson.
Control Panel is your window through the system Registry within the Operating System.

Learn how you can use the Control Panel to manage network settings.


The firewall exists to protect our internal machines from any unauthorized traffic.

The host-based firewall in a Windows Operating System.
The Windows Firewall comes with a whole suite of predefined rules. Learn how you can work with these rules.

Learn how you can put together a Windows Firewall rule using the GUI to enable access to the web server through the firewall.


Learn how you can put together a Windows Firewall rule using the command line to enable access to the web server through the firewall.


Learn how you can use the Control Panel to view connected devices.


The Device Manager allows you to look at device drivers, versions, how devices are connected and how to enable or disable devices.

Learn to work with the Task Manager, and discover some of the Task Manager's hidden gems.

Learn to manage printers and devices in the Control Panel.


If an application stops, somebody logs on or connects that computer over the network, all of this information can be found within the Event Viewer.


In Windows 7, Event Viewer is being modified. Learn how to use the newest version.


Learn how and why to clear an event log.
