GAC = Global Assembly Cache

Let's break it down:

1. global- applies to the entire machine
2. assembly- what .NET calls its code-libraries (DLLs)
3. cache- a place to store things for faster/common access **** So the GAC must be a place to store code libraries so they're accessible to all applications running on the machine. GAC it's a way to keep DLLs (assembly) globally accessible without worrying about the conflicts.

gacutil can be used to find all the assembly installed in GAC.

To install an assembly to GAC use the command --> gacutil -i <assembly name>

To uninstall/removes an assembly in GAC --> gacutil -u <assembly name>
