Since you added a question mark, commands is the correct general term. However there are two types that can be a command. Functions: which are written in pure powershell and cmdlets: which are commands provided by dotnet classes. (Also exes and a bunch of other stuff common to other shells can be a command, but that’s not important.)
The reason they have different names is early on functions didn’t support some of the features available to cmdlets, such as pipeline input. There was later a way to add this support to functions.
In practice call them any of the 3 and people will know that you mean.
