Functions can be compiled separately, and then linked with a program
in which case they are globally accessible.

A function exists in the scope in which it was created.
If a function is part of a script, the function is available to statements within that script. By default, a function in a script is not available at the command prompt.
You can specify the scope of a function. For example, the function is added to the global scope in the following example:
<lang PowerShell>
function global:Get-DependentService
{
Get-Service | Where-Object {$_.DependentServices}
}
</lang>
When a function is in the global scope, you can use the function in scripts, in functions, and at the command line.
Functions normally create a scope. The items created in a function, such as variables, exist only in the function scope.
