First general-purpose computer to be developed was a mainframe. Can be used by many at once, can handle complex problems and large volume jobs. Used for data processing for businesses and scientific applications. Performs many jobs, expensive, introduction to distributed computing. Microcomputer: first development in 1969 and 1971 creating of the first general-purpose microprocessor chip. Performs jobs that were once handled by large computers. Most common function to control operations of the machine which they are in. In phone: memory chip, microprocessor, speaker, lcd, keypad. Processing data (performing calculations and manipulate the info) Outputting the data, display it in some way. Computers allowed us to make advances in many important fields: medicine, military, engineering and more.
