RAM and temporary memory in Intro to Computing - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does RAM stand for and what is its main purpose?

RAM stands for Random Access Memory. It temporarily stores data and programs that the computer is currently using, allowing quick access and fast performance.

beginner

Why is RAM called 'temporary memory'?

RAM is called temporary memory because it only holds data while the computer is on. When the computer is turned off, all data in RAM is lost.

beginner

How is RAM different from a hard drive?

RAM is fast and temporary memory used for active tasks, while a hard drive stores data permanently but is slower to access.

intermediate

What happens if a computer has too little RAM?

If a computer has too little RAM, it slows down because it cannot hold enough active data and must use slower storage like the hard drive to compensate.

beginner

Explain RAM using a real-life analogy.

Think of RAM like a desk where you work. The bigger the desk, the more papers and tools you can keep handy. When you turn off the desk light (computer off), everything on the desk is cleared away.

What type of memory is RAM?

A External memory

B Permanent memory

C Temporary memory

D Optical memory

RAM is temporary memory that stores data only while the computer is on.

What happens to data in RAM when the computer is turned off?

A It is erased

B It is saved permanently

C It moves to the hard drive automatically

D It becomes read-only

Data in RAM is erased when the computer is turned off because RAM is temporary memory.

Which of these is a real-life analogy for RAM?

A A filing cabinet

B A photo album

C A bookshelf

D A desk where you work

RAM is like a desk where you keep things you are currently working on.

Why does having more RAM help a computer run faster?

A Because it allows more data to be accessed quickly

B Because it cools the computer

C Because it increases internet speed

D Because it stores more permanent files

More RAM means the computer can hold more active data for quick access, improving speed.

Which memory type is slower but permanent?

A RAM

B Hard drive

C Cache

D CPU registers

Hard drives store data permanently but are slower than RAM.

Describe what RAM is and why it is important for a computer's performance.

Think about what happens when you open many programs at once.

Use a simple analogy to explain RAM to someone who has never used a computer.

Imagine a place where you keep things you are working on right now.
