Microcomputers (personal computers)
Microcomputers are the most common kind of computers in use as of 2014. The term “microcomputer” was introduced with the advent of systems based on single chip microprocessors. The best-known early system was the Altair 8800, introduced in 1975. The term "microcomputer" has practically become an anachronism.
These computers include:
Desktop computers – A case and a display, put under and on a desk.
In-car computers (carputers) – Built into a car, for entertainment, navigation, etc.
Game consoles – Fixed computers specialized for entertainment purposes (video games).
Smaller microcomputers are also called mobile devices:
Laptops and notebook computers – Portable and all in one case.
Tablet computer – Like laptops, but with a touch-screen, entirely replacing the physical keyboard.
