Networks Chapter 2: Protocols Chapter 5: Physical and Logical Topologies Chapter 6: Numbering Systems Chapter 7: Classful IP Addressing Chapter 8: Classless IP Addressing Chapter 9: Media Chapter Network Devices Chapter LAN Operations Chapter Configuring Routers Chapter To create your own network cables you will first need the equipment we have listed below.

Cat5 cabling is the most commonly used cable used today for networks 2 RJ connectors - These connectors can be purchased at most electronic stores and computer stores and usually come in bulk packages.

It's always a good idea to get more than you expect you will need. To create a network cable you will need a crimper that is capable of crimping a RJ cable not just a RJ cable, which looks similar to a RJ If you do not plan on creating many network cables a knife will suffice.

For simplicity and to prevent potential issues we recommend a wire stripper. Once you have the necessary equipment needed to create your own network cables you need to determine the network cable you wish to create.

There are two major network cables: a straight through cable and a crossover cable. Below are some examples of what cable is used for each of the examples. Straight Through Wired Cables: Straight Through refers to cables that have the pin assignments on each end of the cable.

Straight-Through wired cables are most commonly used to connect a host to client. Crossover Wired Cables: Crossover wired cables commonly called crossover cables are very much like Straight-Through cables with the exception that TX and RX lines are crossed they are at opposite positions on either end of the cable.

Using the B standard as an example below you will see that Pin 1 on connector A goes to Pin 3 on connector B. Pin 2 on connector A goes to Pin 6 on connector B etc. Crossover cables are most commonly used to connect two hosts directly. Examples would be connecting a computer directly to another computer, connecting a switch directly to another switch, or connecting a router to a router. Note: While in the past when connecting two host devices directly a crossover cable was required.

Now days most devices have auto sensing technology that detects the cable and device and crosses pairs when needed. Rollover Wired Cables: Rollover wired cables most commonly called rollover cables, have opposite Pin assignments on each end of the cable or in other words it is "rolled over". Pin 1 of connector A would be connected to Pin 8 of connector B. Pin 2 of connector A would be connected to Pin 7 of connector B and so on.

Rollover cables, sometimes referred to as Yost cables are most commonly used to connect to a devices console port to make programming changes to the device. Unlike crossover and straight-wired cables, rollover cables are not intended to carry data but instead create an interface with the device.

The actual steps you take will vary from problem to problem. Later steps in the process may depend on the results from earlier steps.

Still, it is worth thinking about and mapping out the steps since doing this will help you remain focused and avoid needless steps. So, ping is basically a command that allows you to check whether the host is alive or not.

To ping a particular host the syntax is at command prompt..

It will list all the routers it passes through until it reaches its destination, or fails to and is discarded. In addition to this, it will tell you how long each 'hop' from router to router takes. The syntax is at command prompt.. This tool is especially useful to detect any intrusion attempts. Shows the packets that have been captured during the time.

Dynamic Routing Routing can be accomplished by manually entering the information necessary for packets to reach any part of the internetwork into each router.

A router acts as a dispatcher, choosing the best path for information to travel so it's received quickly.

Switches can be connected to each other, a so-called daisy chaining method to add progressively larger number of devices to a LAN. This book provides the fundamentals of networking and leads you through the concepts, processes, and skills you need to master fundamental networking concepts. Rollover Wired Cables: Rollover wired cables most commonly called rollover cables, have opposite Pin assignments on each end of the cable or in other words it is "rolled over". If you do not subnet, you are only able to use one network from your Class A, B, or C network, which is unrealistic.
