Null in computers, in most programme languages, expresses the absence of data, invalid output, zero data, empty collections, etc. In short, nothing。
In the oxford dictionary, the word null is accompanied by a "technical" symbol, which indicates that the word comes from computer terms and that it was born from the birth of the programme language。
The meaning of the null and the void data was then cited in legal terminology and the phrase “null and void” appeared。

Null was first quoted in english in 1965 and was introduced by the british tony hoare. To the extent that it is widely used, languages are influenced by the microsoft visual basic language. Thus the pronunciation of the term was regulated in english-speaking countries only in 1965。
It is clear that the english dictionary is based on the english pronunciation rule. According to the notes, some of the better-trained programmers in english will read it as “crash”. Because it's a chinese-like, double-written i-pronounced here is negative l, and it's a chinese-like o-throat, which sounds a bit like a “crash”。
But if we go to the relevant videos and listen to the pronunciation of the word, we find that people in english-speaking countries often read the word, eat it, read it, and it's easy to listen to it。

There's a lot of programmers who read the word "freak." is it true that they read it wrong? My answer is not necessarily。
The first reason for reading "angers" was that they were taught by university teachers, and that's what teachers taught them。
The second reason may indeed be that english is not good and that it is not going to look at the sound signs, which, according to the pronunciation rules of the spelling, becomes the “grumpy”。
