| cannot usually be replaced by the user without replacing the hardware | |
| cannot usually be upgraded by the user without replacing the hardware | |
| has definition Software that is designed to run specific hardware devices, and thus is embedded in the devices, usually in a form of read-only memory (ROM) | |
| has hard real-time characteristics and will fail completely if their real-time constraints are not met | |
| has global CPU usage medium | |
| has global development effort low | |
| has global number of copies high | |
| is a subtopic of 1.1 - The Nature of Software | |
| is a kind of software | |
| runs hardware devices such as washing machines, VCRs, microwave ovens, or cars | |
| software | can be easily duplicated | |
| deteriorates as it is changed repeatedly | |
| does not wear out with use like other engineering artefacts | |
| has quality which is only as good as its lowest-quality reusable component | |
| is hard to change correctly | |
| is intangible | |
| is more reliable if it has fewer failures | |
| is designed usually for human beings to use | |
