Computer Network Technology

In the days before computer networking technology was born, the resources that exist on a computer can only be used by computers that have the resources. This is of course cause problems if there is a computer device that should be used together. In addition, data exchange will be very slow because it is done without going through a media that can accelerate the process of data exchange.Of these problems, in the 1940s carried out research by a professor named H. Aiken of Harvard University. After several years of development finally born as a computer networking technology available today. Currently, computer network technology is growing very rapidly, the peak of computer network technology is the Internet that connects millions of computer networks, and in it there are millions more exchange of information every second. According Yuhefizar in an article 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.Suppose a user is located 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, such that all files can be saved or copied into two, three or more computers that are connected to the network. So if one machine breaks, then copy on another computer can be used. 3. Economical, small-sized computer has price / performance ratio that 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. Unbalance ratio of price, performance, and speed is what makes the system designers to build systems that consist of several personal computers. The negative impact of network technology is the cable - the cable that connects between computers in a network can disrupt the aesthetics or beauty of the room because the cable - this cable will appear semerawut or messy if the computer is connected to numerous network. Solutions that can be done is to use wireless networking technology for the wireless network does not use wires or in building a building must be estimated first with cooked to provide a place for planting the cable so the cable does not fall apart.
