# Digital
Digital [technology](tech.md) is that which works with whole numbers, i.e. discrete values, as opposed to [analog](analog.md) technology which works with real numbers, i.e. continuous values. The name *digital* is related to the word *digit* as digital computers store data by digits, e.g. in 1s and 0s if they work in [binary](binary.md).
Normies confuse digital with [electronic](electronic.md) or think that digital computers can only be electronic, that digital computers can only work in [binary](binary.md) or have other weird assumptions whatsoever. **This is indeed false!** An [abacus](abacus.md) is digital device. Fucking normies.
The advantage of digital technology is its resilience to noise which prevents degradation of data and accumulation of error -- if a digital picture is copied a billion times, it will very likely remain unchanged, whereas performing the same operation with analog picture would probably erase most of the information it bears due to loss of quality in each copy. Digital technology also makes it easy and practically possible to create fully programmable general purpose [computers](computer.md) if great complexity.
