Which microcomputer is an example from the Fourth Generation of Computers?

The Apple II is indeed an exemplary representation of the Fourth Generation of Computers, which is characterized by the use of microprocessors. Introduced in 1977, the Apple II was among the first highly successful mass-produced microcomputer products. It played a significant role in the personal computing revolution, largely because it was user-friendly and accessible for individuals and small businesses.

Fourth Generation computers saw advancements due to the ability to put entire processing units on a single chip, significantly reducing size while increasing performance. This generation also brought about the increase of graphical user interfaces, enabling wider adoption and use of computers by the general public.

In comparison, earlier generations, such as the IBM 360 and IBM 370, were large mainframe systems not encapsulated by a single microprocessor. Similarly, the PDP-11 was part of the Third Generation of computers, focused on minicomputers that utilized integrated circuits but did not reach the level of microprocessor technology that defines the Fourth Generation.

Thus, the Apple II stands out as a quintessential Fourth Generation computer due to its innovative use of microprocessor technology and its role in popularizing personal computing.
