Computing Environment — Introduction
A computing emvironment means a particular configuration of layers of software and hardware to run a program.
For example, your computer is running on a particular OS (e.g. mac OS X Yosemite). On it, particular versions of programing language (e.g. Python 3.8), web framework (e.g Django 3.2) and / or many libraries are installed.
When you run a program, it will utilize the sets of these resources which are interlinked each other (called “dependencies”).
As functionalities of software are being updated rapidly (“version update”), a program dependent on another program may not run properly if there is even a single version difference between the dependencies.
There are three typical issues relating to computing environment:
1) Conflict on the same computer
2) Conflict with others’ computers
3) Conflict at test & production stage
The following sections will explain each of the issues.
