- 6. Multiple ChoiceWhich of the following is the best definition for Event handlingProgram designed to run blocks of code or functions in response to specified events (e.g. a mouse click)Coding tasks involved in making your app respond to events by triggering functions.Function specified as part of an event listener; it is written by the programmer but called by the system as the result of an event trigger.A command (onEvent in App Lab) that can be set up to trigger a function when a particular type of event occurs on a particular UI element.

- 13. Multiple ChoiceAll events for an application will come from a user.TrueFalse
- 14. Multiple ChoiceWould it be accurate to describe an Operating system as an Event Driven Application?YesNo
- 15. Multiple ChoiceWhat is the difference between an event trigger and event handler?one creates events, the other listens for themone reports events when they occur, the other waits for themEvent triggers and handlers are the sameOne reports when an event has occurred, the other listens for the event and runs related code
- 16. Multiple ChoiceWhich of these are a benefit to developing an application as Event Driven ?Event Driven code is easier to write and is less complexEvent driven languages are easier to develop in modular sectionsEvent Driven languages are cheaper than other languages to developAll programmers can program in Event Driven languages easily
- 17. Multiple Choice
When pressed, what will a button immediately cause in an event driven language?
Code to be run
Changes to the environment
The user will make a choice and interact with the application
An event to be triggered
- 18. Multiple ChoiceAll events for an application will come from a user.TrueFalse
- 19. Multiple ChoiceWould it be accurate to describe an Operating system as an Event Driven Application?YesNo

- 21. Multiple ChoiceWhich of these indicates that Event driven languages are timely?Time driven'Timely'Service orientatedFeedback loop
- 22. Multiple ChoiceWhat is service oriented ?The application works in real timeThe application aims to provide a serviceThe application tries to support objectsThe application need to be paid for
- 23. Multiple ChoiceWhat kind of element would a "button" be ?CommandControluser InterfaceMenu
- 24. Multiple ChoiceWhich of these is not a controlKeyboard pressMouse clickMouse Move'if' statement
- 25. Multiple Choice
Which of the following is FALSE about Event driven programming?
Event driven programs can be run multiple times with different outcomes based on user interactions
The flow of event driven program cannot always be known ahead of time
Event driven programs do not implement algorithms
Some portion of an event driven program may never execute while the program is still running
- 26. Multiple Choice
What are trigger functions in event driven programming?
trigger functions are functions that save the properties of an event driven program
trigger functions are executed when the user right clicks only
trigger functions choose which event handler needs to be ran for the event
trigger functions play the same role as event handlers
- 27. Multiple Choice
Which of the following is an example of timed event?
Submit button on a form clicked
User typing into a text field
Changing the selected item in the list
Alarm ringing everyday
- 28. Multiple Choice
What is the difference between event loop and event handler?
Event handlers are executed when more than one events occur whereas event loop is executed when one event occurs
Event handlers are lines of code executed when an event occurs where as event loop are lines of code that keep on checking for an event to occur
Both of them play the same role
Event loops are lines of code executed when an event occurs where as event handlers are lines of code that keep on checking for an event to occur
- 29. Multiple Choice
