The document provides a history of computers from ancient times to the present. It begins with the abacus, one of the earliest calculating tools used in Asia for arithmetic. Mechanical computers then emerged between 1650 and 1940, followed by the introduction of electronics between 1940 and 1960, including the invention of the vacuum tube and the creation of the ENIAC, one of the first general-purpose electronic computers. Integrated circuits were developed between 1960 and 1975, allowing millions of transistors to be placed on a single chip. The document then discusses the creation of the Macintosh in 1984 and the rise of computer networks from 1990 to the present. It concludes with a brief discussion of ergonomics and the importance of preventing repetitive strain injuries

22. the mac taps into pent-up desire for ease and pleasure of use Then, during the 1984 Superbowl, you see the first commercial for the Macintosh (directed by Ridley Scott of Blade Runner fame). A crowd of solemn men is gathered in a gloomy auditorium, listening to a ranting bureaucrat on a huge screen. Think of a world full of command-line interfaces… An athletic woman in colorful clothing runs into the auditorium, carrying a huge hammer… … which she throws into the screen, smashing the image and voice of the status quo. hello.

24. Ergonomic tips in using computers Ergonomics is the science of designing the job, equipment, and workplace to fit the worker. Proper ergonomic design is necessary to prevent repetitive strain injuries, which can develop over time and can lead to long-term disability
