• In sequential programming commands run faster than in event-driven programming. 

• In sequential programming each command is run many times in sequence. In event-driven programming all commands are run a single time as an event.

• In sequential programming commands run in the order they are written when code runs. In event-driven programming, commands only run in response to user interactions or other events.
