At their most basic, a template is a page with something on it that you want to be able to add quickly to other pages.

For example, you could create a page called "Template:Hello" with the content "Hi and welcome to the wiki, it's good to have you here"

Then, any time you wanted to say that, you would only have to write and that "Hi and welcome...." text would appear when you save.

Of course, they can get much more complicated that than, but that's the basics.
