What is glob?
Glob or shell globbing refers to the process of matching glob patterns to files in the filesystem. Best to illustrate it with an example: bash shell command cp *.jpg ./thumbnails will copy all files that have .jpg extension to the thumbnails folder. In that context *.jpg is the glob pattern and it will match all the files in the current working directory that have .jpg extension. Think of it as a pattern matching for the filesystem.

Where is globbing used?
Globbing was first introduced in unix system. It is widely used in many tools these days. Gitignore file of the git version control system is one example. Patterns are used to exclude certain files and folders from being version controlled.
Syntax depends on the particular implementation. Minimatch used by this website supports basic wildcards (?*) as well as : brace expansion, extended glob matching and globstar. Go to glob examples section for minimatch examples and syntax details. Details are based on the minimatch documentation and sh documentation.
There are many implementations in almost every programming language.
