In the era before computer network technology is born, the existing resources on a computer can only be used by computers that have these resources. This is of course a problem if there is a computer device that must be used together. Besides the exchange of data will be very slow because it is done without going through a media that can accelerate the process of data exchange.
From this problem, in the 1940s carried out research by a professor named H. Aiken of Harvard University. After severalyears of development finally born as a computer network technology available today. Current computer network technology is growing very rapidly, the peak of computer network technology is the Internet that connects millions of computer networks, and inside there are millions more exchange of information every second.
According to an article in Yuhefizar in ilmukomputer.com, we can menklasifikasikan main benefits / positive impacts of this computer network technology into several sections including:
1. Resource Sharing, can use existing resources together. For example a user who is 100 km away from the data, no difficulty in using these data, as if the data is located nearby. This diatikan that distance troubleshooting computer networks.
2. Realibitas high, with a computer network we will get a high reliability by having alternative sources of supply, for example, all files can be saved or copied to two, three or more computers that are connected to the network. So if one machine breaks, then copy that can be used on other computers.
3. Economical, small-sized computer has a price / performance ratio is better than a big computer. Large computers such as mainframes have a speed of approximately 10 times the speed of personal computers. However, the mainframe computer 1,000 times more expensive than personal computers. Unbalanced ratio of price, performance, and speed makes the system designers to build systems that consist of several personal computers.
The negative impact of network technology is the cable - a cable that connects between computers in a network can disrupt the aesthetic of the room because the cable - this cable will appear semerawut or messy if the computer that is connected to numerous network.
Solutions that can be done that is using wireless networking technology for the wireless network is not using a cable or in constructing a building must be estimated first with cooked to provide a place for planting the cable so that cable clutter.
