THE DAWN OF THE DIGITAL AGE These days computers are everywhere, and we don´t really think about them. But they´re actually a very recent invention and the have developed very quickly. 1940s The first real electronic computers were developed in the 1940. They were huge machines which filled whole rooms at universities and other research facilities. The world´s first digital computer that could store programs was called Baby and was built at Manchester University in England in 1948. “Computers in the future may weigh no more y than 1.5 tons” Popular Mechanics magazine, 1949. 1950s During the 1950s, computers first became available to a few large businesses. They were still huge machines, thought and very expensive. They used magnetic tape to input and store data. 1960s New technology made computers much smaller and much cheaper. The minicomputer became available to even small businesses. 1970s The first microprocessor was launched in 1971 and by the mind-seventies, the first personal computers appeared. These early PCs were still quite large and expansive and used cassette tapes to store data. 1980s Personal computers became affordable and more widely available. At first, when you switched on your new PC, you got a blank screen whit a cursor flashing in the top corner. Then, in 1985, Microsoft launched the Windows operating system, making computing easier for everyone. By the late eighties, PCs were becoming smaller and more portable and laptops were now available. In 1989, Tim Berners–Lee invented the Word Wide Web and the modern digital age really began. READING A.
