The term AMIGA can be broken down into three parts: PAL, A, and MIGA. PAL stands for 'Personal Advanced Logic, ' which was the name of a computer system developed by Commodore International in 1985. The A stands for 'Amiga, ' which was the name of the operating system developed for the PAL computer. Finally, MIGA stands for 'Microprocessor-Independent Graphics Architecture, ' which was the graphics architecture used in the Amiga operating system. Together, these three components form the term AMIGA, which is used to refer to the PAL computer system and its associated operating system.
