Understanding how networks work on a basic level is fairly simple but can quickly become complicated, especially true if you are unfamiliar tonetworks functions. While there will be differences between hard wired and WiFi networks, the basic ideas behind this is very similar. In order to fully understand all of the different complications and complexities that come with computer networks one must start at the beginning.

The most common type of physical connection between computers is through Ethernet. Ethernet uses category five, or Cat 5, cable and an RJ 45 jack to connect up. The cable inside this is usually crossed over, meaning that physical connections on either end are different yet interchangeable. This allows for a better signal and longer length of cable.Once this physical connection has been established the two computers can now talk back and forth. Any computer that has a physical link with the router can now talk to any other computer that has a physical link to it as well. Understanding these basic concepts will allow you to visualize any of the millions of networks around the world.

Now that you have the computers connected up they need a language to talk to each other, is called in a protocol. Over the years many different protocols have been developed, but the most common networking protocol used today is TCP/IP. Others from the past include SPX, IPX, as well as a host of other proprietary ones. While you will find them in use on occasion, TCP/IP is by far and away the most common of all the networks around the world. TCP/IP is actually a combination of two different protocols that work in tandem. TCP, or Transfer Control Protocol, describes how files will be transited between two computers.

Using this protocol, computer can take files and break them down into tiny packets that can be received and built back into the file by the computer on the other end. IP, or Internet Protocol, describes the location of the computer. Each computer that in networks needs to have an IP address. This address will let other computers on the network know where the computer is. Each computer however does not have a unique IP address. This is where things start to get a bit more complicated and understanding how networks work together gets a bit more interesting.

The IP address of every computer will contain four different numbers ranging from zero to two hundred and fifty five. A typical IP address may look something like this: 192.168.1.100. No two computers on the same network can have the same IP address, although two computers on two separate, non public networks can have the same IP address. This does not mean that two computers with the same IP cannot communicate, in fact more than likely the computer your are working on right now shares an internal IP that is the same as many other computers out there in the real world. In order to understand why this is the case you need to be able to visualize how these computers interact. The world wide web is one singular network. Every computer on this network has its own unique IP address. There are certain addresses that cannot be on the world wide web. It’s called as private network address, use in intranet.

This is the basic knowledge about networking, its just a simple for you to learn it.

Every computer that communicates over the Internet must have an IP address according to this article It seems look like our address in the real world. If we want to send a letter to our friends, we have to know her/his address first, so mr. postman not confuse to deliver it. There is two types of IP address, they are static and dynamic.

Static means that IP will be configured by the owner, and never change until the owner change it. This type ussualy use in point-to-point connection. But we have to consider, one IP address just for one computer, so remain that another computer use another IP address. If one IP address used by two computers, there will be make confuse to communicate, because we can not determine wich one.

Dynamic means that IP will be automatically configured when computer boot. We need a server, called DHCP server, that assign IP address to all computer in network. With this, we don’t need to manually set our IP address. Just turn on your computer, you will have an IP address.

There are a lot of types computer communicate each other, but the base type is one-to-one, one-to-many and many-to-many.

In this article we can see a brief description how to connect to internet using IP address.
