A computer is one component of a larger system
A useful system is defined by its purpose and by the relationships among its components.
Computer versus computer system
| Computer | Computer system |
|---|---|
| A programmable electronic device | A connected combination of hardware, software, data, users and procedures |
| Focuses on the device | Focuses on relationships and purpose |
| May operate independently | Often interacts with networks and other systems |
Key idea
A powerful computer does not guarantee a successful system. Software quality, data accuracy, user needs, procedures and connectivity also affect the result.
