Completely Electronic Device (Part II)
Mainframe computers can take up a whole room and can handle the needs of many simultaneous users while processing large volumes of data; they are most often used in large organizations and institutions. Supercomputers, the most sophisticated computers, are designed for extremely high speed processing of huge amounts of data, often using multiple processors working together. They are most often used for performing complex computations by the government, research organizations, and large industrial groups. Fifteen or twenty years ago most books on computers described mainframes, because mainframes were the most common. Today, though, you are more likely to use a microcomputer. The firs micros were sold to computer hobbyists in 1975. In 1977, Apple entered the market with the Apple II, and in 1981 IBM joined the race. Apple released the Macintosh, the cornerstone of its current computer line, in 1984. during the 1980’s, literally hundreds of manufacturers began making microcomputers. The competition kept prices down, and millions of people and businesses bought micros. As the microcomputer industry grew, computer makers constantly tried to lure new customers with more powerful machines. The typical microcomputer sold today can work with more than 200 times as much data as the first IBM PC, and it can work with that data at least 200 times as fast. In fact, many of today’s laptop and desktop microcomputers are more powerful than the minis and mainframes that dominated the market only fifteen or twenty years ago. The power of the modern microcomputer enables it to be used for all kinds of tasks. You can use it to write papers, perform mathematical computations and analyses and conduct research. At home you can use the same computer to communicate with friends, play games, buy airline tickets, and keep track of finances. The same computer can be used again at work for correspondence, financial analyses, compiling and analyzing data, communicating with clients and a thousand other tasks.
