Answer 1

As per my knowledge what i understand this terms, i pasting here..

Cursor: Retrieving data from SQLite databases in Android is done using Cursors. The Android SQLite query method returns a Cursor object
containing the results of the query.Cursors store query result records
in rows and grant many methods to access and iterate through the
records.To use Cursors android.database.Cursor must be imported.

Context: Context is an interface to global information about an application environment. It’s an abstract class whose implementation
is provided by the Android system.

Context allows access to application-specific resources and classes,
as well as calls for application-level operations such as launching
activities, broadcasting and receiving intents, etc.

All the widgets receive a Context parameter in their constructor. In a
regular Android application, you usually have two kinds of Context,
Activity and Application. It’s usually an Activity Context that the
developer passes to classes and methods that need a Context.

DatabaseHelper Class: A good practice for dealing with databases is to create a helper class to encapsulate all the complexities of
accessing the database so that it’s transparent to the calling code.
So, create a helper class called DBAdapter that creates, opens,
closes, and uses a SQLite database.
