Which computer is not classified based on size?

Computers are typically classified based on various attributes, including size, processing power, and purpose. Supercomputers, Mainframes, and Microcomputers are all classifications based primarily on their physical size, capacity, and performance.

• A Digital Computer, however, is classified based on the type of data it processes. Digital computers process discrete data, represented by binary digits (0s and 1s), as opposed to analog computers which process continuous data. Therefore, 'Digital Computer' describes a fundamental operational characteristic rather than a size category.
