The document discusses different ways of classifying computers, including by hardware design (digital, analog, hybrid), utility (general purpose, special purpose), size and capacity (mini, micro, super, mainframe), and modes of use (palmtop, laptop, personal, workstations). It also covers computer languages at different levels (low-level like machine language and assembly, middle-level like C language, and high-level like BASIC, FORTRAN), the binary number system, computer software categories of system software (operating systems, utilities, libraries, translators) and application software (general purpose, special purpose, bespoke).
