What does Code Support mean?

Question

IT education

Please tell me what is Code support, what is code support in general?

Answer 1

There is some code that is already written and working. Someone is using it at work.
Time goes by.
Vulnerabilities and inconsistencies are found in the work of the code. Gotta fix it.
Those working with this code have changing requirements. Needs to be added.
The infrastructure that this code runs on undergoes radical changes that prevent it from working. It is necessary to decide how to adapt it to the changed conditions.
For the sake of the first and second, you need to have a good understanding of this code and the platform on which it is based. For the sake of the third - follow the latest news and trends. In principle, the usual thing for a programmer.
As rightly pointed out by mkone112, working with code, even your own, becomes its support immediately after writing and often takes much more time and effort than actually writing it.
