Many of the applications mentioned here are called Embedded-Systems

They are complete, mainly to fulfill one single application e.g.:

- Mobile-Phone

- Hearing-Aid

- Automotive Control

- „intelligent“ Washing-Machine

- ...

They work like a Computer (PC), but they don´t look like:

- implementing Processor(s)

- have Memory for Program and Data (often very restricted)

- use LEDs / Display, Buttons / Keyboard for the user

- have optional Interfaces for Input and Output

- often battery-powered

They are produced in large quantities:

- Produced in thousands to millions

- ARM Processors have ~80% of the world market
