No doubt, the invention of the computer has revolutionized the world. As they evolved rapidly, new features have been added to facilitate their operation and increase their usefulness. Persons adopted in their homes and businesses began to use to store and process data, as well. Soon, the need to share information between the computers resulted in more effective ways for the transport of the information on disks, but the need for two computers to communicate directly was still very high. Thus, the application for network was born.

Computers today thrive off the coast of connectivity for the world wide web, but the internet was born the idea to have several computers connected together at the same time, able to share data freely. This idea is still very much alive and present today, and it has become easier than ever to configure and use a network to share information quickly and easily.

The basis of a network shape is called and "ad hoc" network, which is essentially just two computers connected to each other to share information. This can be done with a wired connection stability and speed, or a wireless connection, since most computers these days come equipped with wireless network capabilities. Ad hoc networks are typically used to share information quickly and usually are not used for long periods of time, because they may not support all the features that performs a traditional network focused on the router.

A more common network seen in situations more is that which is performed by a "hub" or "access point". These devices act as a point of connection between multiple computers, which allows computers to be aware of the other. Computers can exchange data between them, as the ad hoc, but many network computers can be connected together in this way to form a larger network.

More complex networks to rely on "servers" to manage the data that flows between computers, and can serve as a central point that all computers can access the data from. These types of networks exist generally in large enterprises, because employees may need to store and retrieve data at all hours of the day and require a persistent reliable way to access these data. Also that most people are familiar with power servers store all the information that people need when they want web sites access and internet services.

Establishment of a computer network has been simplified considerably in recent years. What used to require specialized knowledge and sometimes years of training to implement can now be automated with the use of intelligent software and equipment that conforms to established standards.

To set up a home network that allows access to the internet computers, should all of most of the people is a router modem of sorting (according to the company that provides your internet connection, usually by cable or DSL, although that wireless broadband becomes more and more common). Many internet service providers actually provide this equipment rental or purchase to ensure that their customers are using equipment that is compatible and interoperable.

In most cases, the average consumer will not have to look beyond their local electronic retail store to find what they need to set up a home or small business network.
