As more computers connect to a broadband Internet connection

A broadband or high speed connection is what many people currently use in their home. Along with high-speed Internet, many users also use a router to connect multiple computers to the Internet. This document describes how a router is used to connect multiple computers here. To make it easier to understand, I'm going to use, in which we live Internet as a comparison of how the computer is connected to the Internet.
What is an IP address?
IP addresses are a seriesnumbers of the form: nnn, where nnn is a number of 1-3 digits. An IP address is unique to a single computer in a network, such as yours has a unique address. For an Internet connection, an IP address from your Internet service provider (ISP) delivered. In some cases, the ISP gives you more of an IP address that allows you to connect multiple computers here. As discussed below, but you can connect multiple computerswith a single IP address.
Connecting a single computer
Connecting a single computer to the Internet at high speed is your very easy to do. Simply connect a network cable to the modem and then the network card in your computer. The computer then your ISP assigned IP address. For example, if your ISP assigned IP address 24.24.50.17, then the computer has an IP address.
IfMake a request to a server, such as a Web page, the web server know the IP address the request is made. The information is then sent through the Internet and back to your computer. It 's like if someone sends mail to your home. The address on the mail can go home and not elsewhere.
Connect multiple computers
How can you connect multiple computers, whether assigned to a single address? If you have a request for a WebFirst, as it aims to know which computer requested page? We take our home analogy a step further. Let's say that instead of living in a house that you live in an apartment. If someone sends you mail, they belong to not only address but also an apartment. This number is internal to your house and every apartment has its own number. Similarly, multiple computers connected to the Internet when they were all there own local IP address. This canmanaged by a router.
A router is a piece of hardware that is directly to the modem. Each computer is then connected to the router, instead of the modem. Instead of using the IP address from your Internet service provider will now have computers, the router is now that the IP address assigned. This is similar to the router than the home.
The beauty of a router is that it has assigned its own local IP addresses. If you buy a computer with the routerassigned to receive an IP address of the router, similar to each his apartment number. Well, if you make a request for a Web page, the request must be sent to the same IP address, but this time is assigned to the router. If the Web page is returned, the router receives the request and sends it locally on the computer, the requested page.
The router also has its own local database, which is related to the IP addresses of the local computer. So now theRouter has two addresses are assigned to: an outsider from a local ISP and made available to him. This allows the network router to connect to the Internet and the local.
Note: The address is 192.168.xxx.xxx specific IP addresses) reserved for Local Area Networks (LANs.
Managing a Web or FTP server on the network
Let's take a look at this scenario. You have a router connecting multiple computers to the Internet. But now I want to To create an FTP or Web server. No problem. The installation of the necessary software on a computer network, said someone outside the local network IP address of the FTP server and try to connect. Then they discover that they can not connect. Why? His list something only someone like you to give your home number, no address.
The IP address assigned by your computer to your local network. You can connect to the socketComputers on the network but not from the Internet. You must use your ISP assigned IP address (assigned by the router) to have someone from the Internet to your FTP server to connect. The problem is that the router assigns IP and not the computer as an IP address must be unique, how can two computers have the same IP? The answer: they can not, but it is not.
Routers are able to retrieve information about a port forwarda specific computer. A port is a channel number, the data is sent across a network on. You can not see directly as a virtual channel is widely used in network for sending / receiving data. For the FTP server the default port is 21, but you can use another port.
Open the router configuration and find the option for port forwarding. Enter the internal IP address of FTP server and the port number and then save this information. Now, when a user tries toAccess to the FTP site, have the IP address assigned by your ISP to your router to use. The router will then be seen that the data sent to port 21 and then sends it automatically to the FTP server. A Web server can be set in the same way, but the default port is 80, in general,
Note: By default, a router to dynamically assign IP addresses to connected computers. This means that the first computer to connect to the IP router is to get the first availableAddress, and the next gets the second and so on. If you manage an FTP server, it may be easier to assign a static IP address to the computer to make sure the FTP server is always the same IP address.
This article describes how to connect one or more computers to an Internet connection. It 'important that the following points:
If you have a modem connected directly to your computer and your ISP assigned IP address of your computer.
Ifusing a router, the the router will be assigned the IP address from your ISP. Any computers connected to the router will be assigned a local address by the router.
A router will have the ISP IP address and a local IP address. This allows it to connect to both the Internet and your network.
When setting up a computer as a FTP, Web, or other server to communicate over the Internet, it is important to use the router’s IP address to access your server. You will then need to forward the necessary ports on the server.

To connect two computers – Windows
Okay, so why write about it? Well, there was a time I needed to combine the know-how to connect two computers together and I found no article for me and the links on the Internet that it did in detail, then this is for the people's experience could be the same.
So let's begin!
First you need to know how to go exactly your two PC to get in touch. So here it is. The computer connects directly to each other so no hub is required. For thosethat are not connected, a hub is simply a device to the computer over a network using UTP STRAIGHT THROUGH.
The reason why I wrote in capsules is straight, because this is not what you intend to use, it will connect two computers together. Instead, with cross-over cable. You can save them from a local computer to a relatively low cost. Or, if you want to do the job then make it the very simple. If you need help, then do a Google search, as youCrossover cable will be of great help. The reason why I can not tell you how you, not because I tell you how to connect two computers together to create a crossover.
Anyway, that all the requirements you need is just a crossover cable. (Please note, if you buy, or a cross-over, make sure there is at least Cat5e UTP cable.)
Now that we've got that off the road, we go to work!
Step 1
On each computer, right-click on My Computer. "Click Properties and then click"Computer Name" to. Where it says: "Computer Description:" Give each computer a description, which should not (be identical). Now click on "change" so that you can change the computer name and workgroup. Optional name, returning the same name you gave him for his description and job, enter "My first goal" (remember the name of the computer must not be the same, but the name of the working group should be exactly the same onboth)
Be ', if you change this, you will be prompted to restart your computer, simply click Yes or OK, who are always with you will be asked to do so.
Step 2
After restarting the computer, you must configure IP addresses for each computer. This is the following:
On the desktop, locate the icon "My Network Places". Now you dpouble to open it.
Once the map open view on the left to select an option, see "Network Connections" and click on it.
NowRight-click Local Area Network and select Properties.
Where it says: "The connection uses the following items:", scroll to iternet Protocol (TCP / IP) ", click it and click the Properties button.
Now click on "Use the following IP address" and "IP address", enter an IP address as 192.168.0.1.
Although do the same for both computers, you need different IP addresses, so you have the second computer's IP address is 192.168.0.2
AfterIP addresses only the Tab key and you should get a number of subnet mask of 255.255.255.0, then press OK and wait for a bit 'and now almost over!
Step 3
This is the easiest part, just to bring cross-over cable and connect to any computer network RJ45 connector. That's it for now be able to find the computer in "My Network Places". You can start sharing files!
