GST103 is listed among NOUN general-studies courses as Computer Fundamentals. Rather than treating every digital term as a separate fact, connect the concepts to practical study tasks such as organising course PDFs, using spreadsheets and submitting work online.
This supplementary guide explains general digital-literacy skills. Refer to the current GST103 material for its particular units, definitions and assessment requirements.
What you will be able to do
- Identify essential computer components and their roles
- Explain data versus information through a real example
- Choose appropriate software for a student task
- Manage files and basic cybersecurity habits
Lessons with worked examples
1. Hardware and software: working together
A physical device such as a printer, laptop or smartphone is hardware. A word processor and its operating system are software. Neither category solves every student problem independently: saving and printing a document involves both instructions and physical devices.
Think in terms of tasks. A student preparing an assignment needs to enter text, revise it, save it, and possibly export it as PDF. The keyboard or touchscreen takes input, the program handles editing and the storage system retains the result.
- Input devices send data into a system.
- Output devices communicate processed results to a user.
- Software includes system programs and applications.
Worked example — exporting an assignment
You prepare notes in a word-processing program, then select Export as PDF. The application is software; the laptop screen, keyboard and storage are hardware. The resulting PDF is a digital file, not a separate hardware device.
Takeaway: Name the role that a component performs in a workflow.
2. Data, information and simple accuracy checks
Data can be raw values, symbols or observations. Information arises when data are organised and interpreted to answer a question. An unlabelled list of numbers such as 18, 20 and 15 is difficult to use until you know whether those numbers refer to marks, ages or quantities.
Good information needs context, accuracy and relevance. In a spreadsheet, even a small formula error can produce a polished but incorrect total. Treat digital outputs as claims to verify, not automatic proof of correctness.
- Label columns with clear headings and units.
- Check input values before interpreting totals or averages.
- Keep source data separate from your interpretations.
Worked example — calculate an average
Suppose four practice scores are 6, 8, 9 and 7 out of 10. Their total is 30 and average is 30 ÷ 4 = 7.5 out of 10. ‘7.5’ becomes useful information only when identified as an average practice score with the scale stated.
Takeaway: Adding context turns a computed value into meaningful information.
3. Files, folders and everyday productivity
Files can contain text, images, spreadsheets or PDFs. Folders group related files. A helpful naming system makes a digital study library easy to maintain and reduces the risk of submitting the wrong version of an assignment.
File formats are chosen for purpose. A PDF is good for preserving a final document's layout; an editable document format is more suitable for drafting. Avoid changing extensions merely to make a file appear to have a different format.
- Use a consistent pattern such as COURSE_UNIT_TOPIC_DATE.
- Keep a draft and a submitted version where appropriate.
- Check the opened file before uploading it to a portal.
Worked example — avoiding version confusion
Instead of saving ‘final.pdf’, ‘final2.pdf’ and ‘final-real.pdf’, use ‘GST103_Assignment_Draft_2026-10-22.docx’ and ‘GST103_Assignment_Submission_2026-10-22.pdf’. Confirm the contents of the submission PDF.
Takeaway: Meaningful filenames prevent administrative errors.
4. Using the internet responsibly
The internet connects networks and applications, but not every online resource is accurate. Search results, advertisements, official notices and peer discussion posts can look similar. Review sources and avoid sharing personal credentials.
Use browser security updates, manage downloads, verify official domain names and keep backups. When submitting assignments or accessing examination tools, plan for connectivity problems and avoid leaving the task until the deadline.
- Check the website address before signing in.
- Treat unsolicited requests for passwords as suspicious.
- Store study files so they can be recovered after device failure.
Worked example — choosing a source
Two pages provide a claim about course deadlines. One is a current university notice on its official domain; the other is an undated screenshot circulating in a group. The official notice is stronger evidence for the university's current instructions.
Takeaway: Online convenience must be paired with source evaluation.
Apply what you learned — GST103 Practice Clinic
Original independent learning exercise. Try it before opening the worked explanation; this is not an official NOUN examination question.
Check a small spreadsheet before submission
Situation: A student records three assignment marks: 18, 20 and 22. The spreadsheet displays their average as 20, but the middle mark is accidentally stored as text. The displayed result looks right only by coincidence.
Your task: Find the correct arithmetic mean and describe how to make sure the spreadsheet calculation uses all three values.
Reveal the step-by-step solution
- Add the three marks: 18 + 20 + 22 = 60.
- Divide by the number of marks: 60 ÷ 3 = 20.
- Inspect the cell formatting; a number stored as text can be ignored by some spreadsheet functions.
- Convert the value into a real numeric cell, recalculate with a suitable AVERAGE formula and compare it with the manual result.
Answer: The correct mean is 20. If a formula produces a different result, inspect input types, formula ranges and empty cells.
Common mistake to avoid: A spreadsheet output should be checked against the underlying entries, not trusted just because it looks neatly formatted.
Test yourself — original practice questions
These are independently created learning questions, not official NOUN TMA or examination questions. Try each one before revealing the explanation.
Question 1. Which is an input device?
- Printer
- Monitor
- Keyboard
- Speaker
Show answer and explanation
Answer C: Keyboard
A keyboard provides input to the computer.
Question 2. Why is a spreadsheet label important?
- It increases screen size
- It explains what the values represent
- It proves every number is correct
- It replaces a calculation
Show answer and explanation
Answer B: It explains what the values represent
Labels supply context for data.
Question 3. Which file is best identified as a final submission?
- notes-temporary.tmp
- assignment-maybe.doc
- GST103_Submission.pdf
- untitled
Show answer and explanation
Answer C: GST103_Submission.pdf
The descriptive name and final document format help identify intended use.
Question 4. Which response is safest when a stranger asks for an account password?
- Provide it to speed up support
- Share it only in a large group
- Decline and use official support channels
- Write it in a public comment
Show answer and explanation
Answer C: Decline and use official support channels
Passwords should not be shared as part of informal support requests.
Three things to practise this week
- Create a subject folder and write a consistent naming convention for your files.
- Build a small table of four scores and calculate their average by hand and in a spreadsheet.
- List three warning signs of a suspicious login page.
