__________ helped spawn one of the first electronic digital computer.
Eniac was used to do what? __________________________________________________
Eniac was huge- how many switches did the video say it had? __________________________
In 1948, ____________________ Labs introduced the transistor, an electronic device that carried and amplified electrical current but was much smaller than the cumbersome vacuum tube.
Ten years later, scientists at Texas Instruments and Fairchild Semiconductor came up with the ___________________________________, an invention that incorporated all of the computer’s electrical parts–transistors, capacitors, resistors and diodes–into a single silicon chip.
Microprocessors were the size of a ____________________________, and they could do things the integrated-circuit chips could not: They could run the computer’s programs, remember information and manage data all by themselves.
In 1971, the first microprocessor was sold by ____________________.
These innovations made it cheaper and easier to manufacture computers than ever before. As a result, the small, relatively inexpensive “microcomputer”–soon known as the _______________________–was born.
In 1976, 2 men introduce the 1st BASIC programming language for the Altair- their names were? ________________________________ & _____________________________________
Intel chips keep getting (larger or smaller) over the years.
This area, where processors are made, is now known as __________________________________
In April 1977, Jobs and Wozniak introduced the ________________, which had a keyboard and a color screen.
Name 4 of the companies that began entering the PC revolution:
Innovations like the _______________________________________, which allows users to select icons on the computer screen instead of writing complicated commands, and the computer mouse made PCs even more convenient and user-friendly.
