SharePoint Definitions:
Check-out: To lock a file while editing it to prevent others from overwriting or editing it inadvertently. Only the user who checks out a document can edit the document.
Home Page: A Home Page is the main page of a SharePoint web site; it provides a navigational structure that links the site components together. The home page has two major navigational areas: the top link bar and the quick launch bar.
Library: A library stores files as well as information about files. You can control how documents are viewed, tracked, managed and created in libraries.
List: A list is similar to a library, except that it is a collection of information where your college or department can store, share and manage information (not files).
Versioning: The process of creating a numbered copy of a file or an item whenever a revision is saved to the library or list.
Web Part: Web parts are basic building blocks of a web part page. A Web Part can be reused, shared and personalized by all users who have permission to access it.
Web Part Page: a special type of page on a SharePoint site that contains one or more web parts.
