Templates are a type of page that contain boilerplate text that is intended to be displayed on more than one page in Wikipedia.
This Tip of the day box is an example of a template (there are several versions actually), and besides being displayed here it is displayed on many userpages as well.
Template names start with the prefix "Template:" followed by the page name. The main version of the template you are reading right now is called "Template:totd".
To display a template on a page, go to the target page, click "edit", and add the template's name (with or without the prefix) surrounded by double curly brackets to the page's source text. (The text you see in the edit box when you click edit this page is called "source text", because it is a lot like programming code, which is called "source code").
Including a template on a page in this way is called "transclusion". Here's an example:
Committed identity: c94fff8096b1e248747397e879248fe79241bd7f68986f4e0e00224b58c7ec0a7c79fe6258885ccd9881d15794aabaa563d4456740777974441f67ff96192c3a is a SHA-512commitment to this user's real-life identity.
