3.4 Microbit RETRIEVAL PRACTICE

In computer programs an _______ is something that happens.

• surprise

• event

• divide

• code

Pick two ways in which the BBC micro:bit can sense many different events?

• milkshake

• screen down

• free fall

• skyfall

Functions will only run their instructions when the function is ‘called’.

• True

• False

• Sometime

Why do we only have to create a function once, and then the function can be used again and again throughout the same program?

• Can't compare the speed of a function as it is a trick question.

• All functions just works well when a programmer does it.

• This can make it run quicker as the function dog will run for it.

• This can reduce the number of instructions needed, and make programs more efficient.

Can you make as many functions as I want or need?

• Yes

• No

• Sometimes

pause (ms) blocks means?

• Pauses in muti-seconds

• Pauses in mini-seconds

• Pauses in miliseconds

• Pauses in make code seconds

Referring to the image, how many times does the program repeats the intstructions?

• 1

• 2

• 3

• 4

• forever

String in computing means...

• The BBC micro:bit needs a special computer programmed as hexadecimals

• A computer program are often referred to as code

• Is a data-type, and usually means any information that is stored as text. In BBC micro:bit blocks we can store data as either (text) or numbers.

• Computers contain the instructions that enable computers to do something useful.

Iteration in computing means...

• The BBC micro:bit needs a special computer programmed as hexadecimals

• The Computing term for repeating code again and again

• Is a data-type, and usually means any information that is stored as text. In BBC micro:bit blocks we can store data as either (text) or numbers.

• Computers contain the instructions that enable computers to do something useful.

How do computers make decisions in makecode editor?

• Uses an IF, THEN ELSE block

• Uses an END IF block

• Uses all the logic blocks together

• Uses a sequence of commands that make sense
