An activity is a general name for a group of features in a Moodle course. Usually, an activity is something that a student will do that interacts with other students and or the teacher.
An Activity, such as Forums or Quizzes, properly means something students can contribute to directly, and is often contrasted to a Resource such as a File or Page, which is presented by the teacher to them. However, the term activity is sometimes for convenience also used to refer to both Activities and Resources as a group.

A resource is an item a teacher can use to support learning, such as a file or link. Moodle supports various resource types that teachers can add to their courses.
Book - A multi-page resource in a book-like format, with chapters and subchapters. Books can contain media files and well as text and are useful for displaying lengthy passages of information that can be broken down into sections.
File - A picture, PDF file, spreadsheet, sound file, video file or any other file type. Where possible, the file will be displayed within the course interface; otherwise, students will be prompted to download it.
Folder - For helping organize files. A folder may contain other folders.
Page - A web page that a teacher creates using the text editor.
URL - For providing a web link as a course resource.
