What is the main differences between site definition and site template?

• Feature Stapling
  • Site Definition: Supported
  • Site Template: Not supported
• Multiple webs
  • Site Definition: Can provision multiple webs.
  • Site Template: Can only provision one web.
• Complexity
  • Site Definition: Complex to create
  • Site Template: Easier to create
• Permissions
  • Site Definition: Requires admin access to server for deploying.
  • Site Template: Installable from a Web UI by site owners.
• Performance
  • Site Definition: Files are on disk, better performance.
  • Site Template: Files are in database, less efficient.

Difference between List and Library?

Although in most of the UI and API they can be manipulated the same way, there are some significant differences between Lists and Libraries. The latter is a specialized type of the former.

Lists:

• Can have attachments
• Have major versions only
• Do not have Check-in/Check-out features

Libraries:

• Cannot have attachments (files are directly in the library)
• Have both minor (draft) and major (published) versioning
• Have Check-in/Check-Out
• Publishing Libraries can use Page Layouts
• Have Unique Document Ids out of the box

In code, you can always obtain an SPList from a SPDocumentLibrary but not the other way around.
