Two computers that are connected through a router are actually on separate networks if properly configured. Having a computer communicate another on a different network is a complex process, but Packet Tracer makes it easy to setup the design and configuration.In about 10-15 minutes, the most basic of all networks can be constructed and working.

The running configuration of the router can be accessed by using a console cable and setting up a connection from one of the desktop machines. The console cable isn\’t necessary for Packet Tracer, but if you plan on programming a real router you will definitely need one. You will also need a crossover cable so that you may connect the desktop machines to the router\’s individual Ethernet ports.

Each of the computers on the network will need an IP address for routing information from one network to another. You will also have to assign an IP address to each Ethernet port of the router. The Ethernet port connected to a single desktop machine will share the same network address, but will have a different host address. There will be two separate networks; one on each of the Ethernet ports. The IP address you assign may not be a reserved number or duplicated among ports.

Even with all of the IP address information in place, and the Ethernet ports configured, there is still something missing. We haven\’t installed a gateway address on the desktop machines. Without a gateway address, the computer won\’t be able to send and receive information over the network. It\’s simple to assign: the gateway address is going to be the IP address of the Ethernet interface that is connected to the desktop in question.

We can confirm that the network was set up properly by pinging a computer from another. As long as you did everything correctly, you should get a success message when using the command line interface. If you get an error regarding a time out, odds are you have input the wrong IP address information or forgot to open the Ethernet ports of the router. Troubleshooting is a valuable skill to have, so try to fix the problem yourself before asking for help if you get stuck on a problem.

Final Thoughts

A basic network is easy to setup in theory, but harder to actually create. Confusing Cisco IOS commands and problems such as a faulty cable is enough to give anyone a hard time. Internet tutorials and troubleshooting tactics are a good solution if you have hit a stumbling block.

Using Packet Tracer To Design A Small Computer Network is a post from: Computer Troubleshooting

As routers are connected to networks, look for a program that includes basic networking skills (for example Network+, perhaps with A+) before you start a CCNA. You must have a basic grasp of networks prior to starting your Cisco training or the chances are you’ll fall behind. When you’ve qualified and are on the job market, companies will expect good networking skills in addition to the CCNA.

Start with a bespoke training program that covers everything you need to know prior to commencing your Cisco training.

One useful service provided by many trainers is a programme of Job Placement assistance. The service is put in place to assist your search for your first position. However sometimes people are too impressed with this facility, for it is genuinely quite straightforward for well qualified and focused men and women to find a job in this industry – because there’s a great need for skilled employees.

Ideally you should have CV and Interview advice and support though; also we would encourage any student to work on polishing up their CV the day they start training – don\’t procrastinate and leave it until you\’ve graduated or passed any exams.

You might not even have got to the exam time when you will be offered your first junior support job; but this can\’t and won\’t happen if your CV isn\’t in front of employers.

Generally, you\’ll receive quicker service from a local IT focused recruitment consultant or service than you\’ll experience from any training provider\’s employment division, because they\’ll know the local area and commercial needs better.

Just ensure you don\’t invest a great deal of time on your training course, and then do nothing more and imagine someone else is miraculously going to find you a job. Stand up for yourself and get on with the job. Put as much resource into getting a good job as it took to get qualified.

We can\’t make a big enough deal out of this point: You have to get round-the-clock 24×7 instructor support. You will have so many problems later if you don\’t heed this.

You\’ll be waiting ages for an answer with email based support, and telephone support is usually to a call-centre that will make some notes and then email an advisor – who\’ll call back sometime over the next 1-3 days, when it\’s convenient to them. This is no good if you\’re lost and confused and can only study at specific times.

Top training providers tend to use a web-based 24 hours-a-day package pulling in several support offices across the globe. You\’re offered an environment which seamlessly accesses whichever office is appropriate any time of the day or night: Support when you need it.

If you accept anything less than direct-access 24×7 support, you\’ll very quickly realise that you\’ve made a mistake. You might not want to use the service late at night, but you\’re bound to use weekends, early mornings or late evenings.

A study programme should always lead to a fully recognised major qualification at the finale – not a useless \’in-house\’ plaque for your wall.

From the perspective of an employer, only the big-boys like Microsoft, Cisco, CompTIA or Adobe (for example) will open the right doors. Anything less just doesn\’t cut the mustard.

Beginning from the idea that it makes sense to choose the job we want to do first and foremost, before we can even chew over which method of training meets that requirement, how are we supposed to find the right direction?

Flicking through a list of IT job-titles is no use whatsoever. The majority of us don\’t really appreciate what our own family members do for a living – so we have no hope of understanding the ins and outs of a specific IT job.

Reflection on many issues is important if you need to expose the right answer for you:

* Your personality can play an important role – what things get your juices flowing, and what tasks you really dislike.

* Are you aiming to accomplish a key aspiration – like being your own boss someday?

* What priority do you place on travelling time and locality vs salary?

* Because there are so many different sectors to gain certifications for in Information Technology – you will have to pick up some background information on what sets them apart.

* The time and energy you\’ll have available to commit getting qualified.

For most people, dissecting each of these concepts requires a good chat with someone who can investigate each area with you. And not just the certifications – but the commercial requirements and expectations of the market as well.
