You and the Internet :: Computers Web Technology Essays
You and the Internet Have you heard all about the internet? Have you heard all about the wonderfull places you can go to just by clicking a button on your computer screen? Wouldn't it be wonderfull if that were really true? A lot of exaggerations have been made about the internet. But for the money there's nothing like it on Earth. The internet is no electronic transportation device. The internet is a multinational packet switched computer network. For those of you who aren't familiar with the "packet switched network" I will explain. A data transmission can be compared to a freight train. Each boxcar is numbered. The "network" can be compared to a railroad track network with switch yards referred to as "nodes." Prior to 1970 the only way to get a freight train from, say, Los Angeles to Boston was to reserve the entire distance of track for this single train. With a packet switched network each boxcar is no longer attached to a train. With it's assigned number each boxcar or packet could navigate whichever track was available through whichever switch yard it found all the way to the destination. As each boxcar arrives at the destination the final switchyard must reassemble the freight train in sequential order and send the data to the end user. Among the more than 19.5 million sites you will find universities, libraries, governments, corporations and individuals. This huge assortment of sites is just waiting for you to visit, get comfortable and start learning. There are almost 12,000 newsgroups where you can learn about the most recent developments on just about any subject which interests you. You can subscribe to any newsgroup. That means that all the latest developments will be sent to your e-mail (electronic mail) box. This way you can have the latest news on any subject which is of continuing interest to you. Do you have an interest or gripe about anything? Send some e-mail to the people or corporations responsible. It's not difficult to find the addresses. You'll find most companies or organizations quite eager to respond. This is also a great way to do research. You can create a form letter which might ask "What is your company doing to reduce pollution?" and send it to a thousand companies in the US. I can assure you that the results you receive will be overwhelming. The internet there are about 1700 sites designated as IRC or internet relay chat.
