Digital [computer](computer.md) [technology](tech.md) is that which works with [whole numbers](integer.md), i.e. discrete values, as opposed to [analog](analog.md) technology which works with [real numbers](real_number.md), i.e. continuous values (note: do not confuse things such as [floating point](float.md) with truly 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). By extension the word *digital* is also used to indicate something works based on digital technology, for example "digital currency", "digital music" etc.
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 a digital device, a book with text is a digital data storage. Fucking normies RIP.

{ Apparently it is "digitisation", not "digitalization". ~drummyfish }
The advantage of digital technology is its **resilience to [noise](noise.md)** 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) of great complexity.

A **typical example** of analog versus digital technology is wrist watches: analog ones have rotating hands to show time, digital ones use digits -- note that it doesn't matter if is the watch is electronic or not, the distinction is in how time is shown. A hand rotates continuously, it may be positioned at any arbitrary angle, basically with "infinite resolution", whereas digits are discrete, non-continuous -- a digit will instantly switch to being a different digit. This is the distinction between analog and digital.
