Computer Science Unit 2

1. What is a computer processor?

• Where the computer stores its memory

• The face of the micro:bit

• The area of a MakeCode project that shows how a program looks when run on the micro:bit

• A small chip inside the computer that the computer uses

  to process and transform information

2. What is the difference between RAM and hard drive memory?

• RAM is the computer’s short-term memory and the hard drive is where the computer stores its long-term memory

• The hard drive is where the computer stores its short-

  term memory and RAM is the computer’s long-term

  memory.

• RAM is used for programming and the hard drive

  memory is for storage.

• Hard drive memory is for storing files and RAM is used

  for processing inputs.

The term input describes:

• A type of RAM memory

• A computer speaker

• How a computer takes in information from the world

• How a computer processes information

The term output describes:

• How a computer displays or communicates information

• The way a computer stores memory

• Where cords, like a USB cable, connect to a computer

• A type of RAM memory

What’s an algorithm?

• The word used to describe all computer codes

• Sets of instructions to a computer

• A type of hardware used with micro:bit

• The area of a MakeCode project that shows how a

  program looks when run on the micro:bit

What’s a function machine?

• One that takes an input, processes the input, and then

  delivers an output

• One that can understand many different coding

  languages

• A computer designed for a single task

• A peripheral machine that connects to a computer

Is a micro:bit an example of hardware or software?

8. What is pseudocode?

• The coding blocks in MakeCode

• A detailed step-by-step plan for your program

• A coding language

• A computer program

What is an event in programming?

• An action done by the user, such as pressing a key or clicking a mouse button

• A computer program

• A computer designed for a single task

• The coding blocks in MakeCode

What is an event handler?

• A type of RAM memory

• A coding language

• A routine that responds to an event

• A computer speaker
