Understanding How much RAM different tasks need in ACARA Digital Technologies Years 7–8

What it does: Each tab takes a slice of memory. Many tabs together add up to a lot of GB, which can use up most of an 8 GB computer. Adding up the memory used by each open program shows the total RAM needed. Running several programs at once pushes the total up. Big video files and editing software use lots of memory at once, so 16 GB or more is a better fit. Different tasks need different amounts. Heavy tasks with big files and many programs need more RAM. Tabs and programs add up. When they use all the RAM, the computer slows down.

Common mistakes: Web browsing and documents run smoothly on about 8 GB of RAM. 16 GB is for heavier tasks like editing and gaming. The line should be ramNeeded <- 8. Gaming uses big files and many background programs, so it needs 16 GB or more. 8 GB suits web and documents. The line should be ramNeeded <- 16.

Quick Questions

1. Which device is more likely to run smoothly for just web browsing and Word documents?
A. A laptop with 8 GB of RAM ✓
B. A laptop with 2 GB of RAM and many tabs open
8 GB of RAM is enough for everyday web and documents. Much less than that can struggle once several things are open.
2. Video editing with big 4K files usually needs...
A. 16 GB of RAM or more ✓
B. 4 GB of RAM is plenty
Big video files and editing software use lots of memory at once, so 16 GB or more is a better fit.
3. True or false: Each browser tab uses some RAM, so lots of open tabs add up.
A. True ✓
B. False
Every tab holds a web page in memory. Thirty tabs can use several GB together.
4. Which task needs the MOST RAM?
A. Typing one short document
B. Playing a modern game while streaming and chatting ✓
More programs running at once means more GB of RAM is needed. A single document needs very little.
5. Which statement about RAM and tasks is correct?
A. The number of GB of RAM you need is the same for every task
B. The more programs and bigger files open at once, the more GB of RAM you need ✓
Different tasks need different amounts. Heavy tasks with big files and many programs need more RAM.

Match the Pairs

RAM: 8 GB → Enough memory for everyday web browsing and documents
RAM: 16 GB or more → Memory for heavy tasks such as video editing and gaming
Browser tabs add up: every open tab uses some RAM, so 30 tabs need far more than 3 tabs → tabs: 30 x 0.2 GB = 6 GB
The more programs and bigger files open at once, the more GB of RAM a task needs → game 8 GB + video call 2 GB + browser 3 GB = 13 GB
Task: 4K video editing -> RAM: 4 GB → 4 GB is far too little for video editing. Big video files and editing software need 16 GB or more.
Having 40 browser tabs open needs no extra RAM → Browser tabs add up. Each open tab uses some RAM, so many tabs need more GB in total.

Key Term

GB of RAM
How much memory a task needs. More programs and bigger files open at once need more GB. 8 GB suits web and documents; 16 GB or more suits editing and gaming. Browser tabs add up.

Fill in the Blanks

1. Web and documents need about 8 GB of RAM
Hint: Type the number of GB that suits everyday web browsing and documents.
2. Editing and gaming suit 16 GB or more
Hint: Type the other heavy task that needs lots of RAM, besides editing.
3. 10 tabs x 0.5 GB each = 5 GB of RAM
Hint: Multiply the tabs by the RAM each one uses. Browser tabs add up.
4. A laptop with 16 GB of RAM
Hint: Type the unit used to measure the size of RAM.
5. Bigger files open at once need more RAM
Hint: Type the word that describes how much RAM bigger files need compared with smaller ones.

Spot the Error

Question 1
A task <- 'web and documents'
B tabs <- 5
C ramNeeded <- 16
D OUTPUT ramNeeded
Line C — Web browsing and documents run smoothly on about 8 GB of RAM. 16 GB is for heavier tasks like editing and gaming. The line should be ramNeeded <- 8.
Question 2
A task <- 'gaming'
B files <- 'large'
C ramNeeded <- 8
D OUTPUT ramNeeded & ' GB'
Line C — Gaming uses big files and many background programs, so it needs 16 GB or more. 8 GB suits web and documents. The line should be ramNeeded <- 16.
Question 3
A tabs <- 10
B ramPerTab <- 0.2
C totalRam <- 0
D totalRam <- tabs + ramPerTab
Line D — Browser tabs add up: every tab uses its own memory, so the total is tabs multiplied by RAM per tab. Adding is wrong. It should be totalRam <- tabs * ramPerTab.
Question 4
A task <- 'photo editing'
B ramGB <- 2
C OUTPUT task & ': ' & ramGB
Line B — Photo and video editing use big files, so they need 16 GB or more of RAM. 2 GB is far too small to run smoothly. The line should be ramGB <- 16.
Question 5
A openProgramsGB <- 12
B IF openProgramsGB < 8 THEN
C OUTPUT 'Choose 16 GB RAM'
D ENDIF
Line B — The programs use 12 GB, which is more than 8 GB, so the advice to choose 16 GB should show. The comparison must be > not <. It should be IF openProgramsGB > 8 THEN.
