They all mean “during the time that” and can be used to introduce a long action that started before a short action.
e.g. When/While/As Millie was watching TV,
Andy came into the sitting-room.

Tip
We use past continuous tense for long actions
and past tense for short actions.

If the longer action is in the main clause, we
often use “when” to join them.
e.g. Millie was watching TV when
Andy came into the sitting-room.

2. When there are two long actions, we often
use “while”.
