This module handles all things that are so basic to all other modules that they can be seen as a layer of common services to the entire system. One of the tasks is to provide platform-independence of file, date&time, threads, and more.
The difference with the 'General' module was, traditionally, that Basic utilities could in principle be insteresting outside OpendTect. This distinction is not enforced (see e.g. the survey info class). We place things in Basic that feel more basic than General. Note that General depends on Basic, not vice versa. Basic algorithm-type things go in Algo.
You'll find that many of these tools can be found in other packages in some form or another. But, the problems of management of dependencies are usually much bigger than having to maintain a bunch of lean-and-mean specially made objects that do selected things in a way that fits our system.
We'll just name a few groups of services. There are many more isolated useful objects, defines, functions and so forth.
