This part contains a survey of the world of computer hardware. This chapter introduces computer hardware and provides a very short history of computing. This section introduces the computing environment thrugh a brief history of computers and an overview of the subjects within hardware.
Outline of computer history[edit | edit source]
There is some disagreement about when the digital age began. After all, the Babylonians used a kind of abacus about 500 BC. If we call it the computer age, we can get a much cleaner mark. 1951 was a watershed year, and two events identify it as the beginning. The UNIVAC became the first commercially available digital computer. That same year a research team at MIT completed the first user-interactive computer (named Whirlwind) that used a keyboard and a television screen or CRT. Considering developments by decades gives a pretty clear picture of the evolution of computers.
- 1950s the vacuum tube decade - introduction of computers and their use in business and major scientific research;
- 1960s the mainframe decade - transistor-based computers used in business;
- 1970s the PC decade - the first CPU on a chip to widely available personal computers;
- 1980s the software decade - windows, games, and spreadsheets make the PC useful;
- 1990s the internet decade - creation and then commercialization of the Web.
