Development of Internet

More and more people nowadays are interested to be known about all events, in taking some information quickly. With the help of Internet you can make it easily.

Back in the 1960th, at the time of cold war, Pentagon needed military systems that would continue to work even the phones and radio had broken down. In 1964 Paul Baran connected 4 computers in different parts of the USA and posted a message.

You couldn’t destroy Internet – if some computers will be broken down, the rest will work well. Nobody owns the Internet, and no organization controls its use.

Now millions of people around the world are logging into libraries, call up satellite weather photos, download computer programs and music, take part in discussion groups. Even the Presidents have their own Internet accounts. In fact, anyone with modem connected to the phone line can enjoy Internet.

The total number of people in Russia, who get into Internet, due the Putin’s statistics, is 10 million. In the modern Europe this number is much more – there are more than 200 million Internet users.

In future all technics will be connected to the Internet. Now we can connect with Internet mobile phone, photo camera, palm computers and even alarm clock. Now we can be connected with all the world everywhere – in the bus, underground and even on the north pole.

Supercomputer and Mainframe

Supercomputer is a broad term for one of the fastest computers currently available. Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations (number crunching). For example, weather forecasting requires a supercomputer. Other uses of supercomputers scientific simulations, (animated) graphics, fluid dynamic calculations, nuclear energy research, electronic design, and analysis of geological data (e.g. in petrochemical prospecting). Perhaps the best known supercomputer manufacturer is Cray Research.

Mainframe was a term originally referring to the cabinet containing the central processor unit or "main frame" of a room-filling Stone Age batch machine. After the emergence of smaller "minicomputer" designs in the early 1970s, the traditional big iron machines were described as "mainframe computers" and eventually just as mainframes. Nowadays a Mainframe is a very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously. The chief difference between a supercomputer and a mainframe is that a supercomputer channels all its power into executing a few programs as fast as possible, whereas a mainframe uses its power to execute many programs concurrently. In some ways, mainframes are more powerful than supercomputers because they support more simultaneous programs. But supercomputers can execute a single program faster than a mainframe. The distinction between small mainframes and minicomputers is vague, depending really on how the manufacturer wants to market its machines.
