Following my instincts when it comes to any job that I do, be it blogging or the primary job that I am involved in, that is Programming and Networking, makes my job easy for me and it also reduces the number of errors that I usually run into. Well, I was never too committed to my previous job because the only time that I learnt by staying at the job was when I was in training. Guess how much time the training was for???? Well, 2 weeks I should say. Thats the reason I quit my job.
Anyways, whatever I learnt should be exercised so as to remember it and so that I don’t lose my knowledge. So, I thought the best way to utilize my knowledge was to share with you folks who would like to fill in their hungry brains with some techie know-how. The job was simple….
A person would tell me that he is not able to go online….
And what was my goal? To make him go online. Well, the only flaw in this communication b/w me and the customer was that neither nor I was aware where the problem lay in the network. That was the biggest ordeal. Anyways, I think that I did pretty much as I could possibly remember from what I learnt and guess what, I even managed to get a 78% hit rate( solved queries). Thats good, ain’t it?
Ok, lets get to the topic…
First of all lets talk about routers.
Router:
Forgive me guys, I know that most of them reading this post know what a router is. But I have to reach to the broader populi and for that I would like to extend my description to a couple of words more than that is required. A router is basically a device that provides a single internet connection to more than one computer. Yes, it basically bifurcates the internet connection to more than one.
So, what are the jargons???
We have what we call as the firewall for the router so that the internet connection is protected from unauthorised intrusion, we have the DMZ so that we can put certain computers unprotected from the firewall. This is because certain applications like connecting an XBOX to the computer via the router requires the firewall to be turned off, an application where DMZ comes into the picture. (DMZ stands for DeMilitarized Zone).
So there are two ways of connecting the router to work as a ROUTER. One would be by using the setup CD that comes along with the router while the other one would be manual wherein we access a special page called the router setup page to get the router configured. We use the browser to reach the router setup page(rsp).
So, how to reach the rsp. Well, just as we open a webpage that has a particular ip address, the router also has an ip address. Just how do we know the ip address of the router? For one, the ip address is given along with the manual of the router itself. Otherwise we can find out the ip address by the following method….
Click Start and click on Run->type in cmd and open command prompt. We will see a black box coming up that addresses itself as command prompt. Well then, half the job is done. Next, we type in “ipconfig” on the black box where we see the cursor blinking and voila! we see several lines of text coming up. Just search for ” Ethernet Adaptor Local Area Connection “. Do we see three options that say
1: ip address
2: subnet mask
3: default gateway?
The default gateway is the ip address for your router in most of the cases.
Next class tomorrow(Type the default gateway on the address bar of your browser and see the magic)……….
