Every time someone says "my laptop is slow" or "that app won't install", they are really talking about the relationship between hardware and software. Today you will learn the difference at a practical level, so when you plan what you need for your Something Real project, or argue for a better setup on Work Experience, you can say exactly what the problem is and what would fix it.
Look at the device you are using right now. What are three physical parts you could point at, and three apps or programs you could name? Then decide: where does "the internet" fit, is it hardware, software, or something else?
Four ideas underpin every conversation about computers. If you can hold these in your head, you can talk to any tech-support person, employer, or parent about what a machine can and cannot do. Most "my computer is broken" complaints are actually software problems, not hardware faults, so these four labels help you spot where the real issue sits.
| Concept | Why it matters | Example |
|---|---|---|
| Hardware — the physical parts of a computer you can touch (screen, keyboard, CPU chip, drive) | If your machine cannot run the software an employer uses, it is usually a hardware limit. | A Centra checkout till has a barcode scanner (input hardware), a receipt printer (output hardware), and a small PC hidden inside the counter |
| Software — the programs and apps that run on the hardware, including the operating system (Windows 11, macOS, ChromeOS) and apps like Word or Chrome | Software upgrades are cheap and usually just a download; hardware upgrades mean buying new parts. | The same EPOS till software runs on different hardware from shop to shop, but the cashier's workflow stays the same |
| Input vs output — input devices send information in (keyboard, mouse, microphone, webcam); output devices show results (screen, speakers, printer) | Knowing the difference makes troubleshooting quicker: if nobody can hear you on a call, the problem is almost always the mic (an input). | A webcam captures video (input); a monitor displays video (output); a headset with a mic is both |
| Storage vs RAM — storage (SSD or hard drive) keeps files permanently; RAM is short-term working memory that empties when you shut down | More RAM fixes slowness with many apps open; more storage fixes running out of room for files. | A 256 GB SSD holds thousands of documents and photos; 8 GB of RAM keeps many browser tabs and a couple of apps open at once |
In this activity you will take a labelled tour of the machine you are sitting in front of right now. First the outside, then the inside (via System Settings). You will collect the specs you need for your My Machine page later in the lesson, so jot them down on paper or in a scratch document as you go.
Pick the tab for your operating system. If you are not sure which OS you have, look for a Windows logo in the bottom-left taskbar (Windows), an Apple menu in the top-left (Mac), or a circular launcher in the bottom-left and a Google account icon (Chromebook).
| Issue | Solution |
|---|---|
| I cannot find the Settings option described | Use your OS's built-in search. On Windows, press the Windows key and type "about"; on Mac, press {{kbd:Cmd+Space}} and type "about"; on Chromebook, open the Launcher and type "settings". |
| My CPU line shows numbers and letters I do not understand | You only need the processor family name (for example "Intel Core i5", "AMD Ryzen 5", or "Apple M2") and the generation if shown. Ignore the GHz number unless you are comparing two machines head-to-head. |
| My storage shows used and free as two separate numbers | Use the total. If your About page says "128 GB of 256 GB used", your total storage is 256 GB. That is the number that matters. |
Before you build your own page, here is the layout yours should follow. Your numbers will be different, but the sections will be the same. Read it once so you know what you are aiming for, then you'll build yours in the next step.
My Machine Device: Dell Latitude laptop (school-issued) CPU: Intel Core i5, 11th generation RAM: 8 GB Storage: 256 GB SSD OS: Windows 11 Education Input devices - Built-in keyboard - Trackpad - Webcam and microphone (above the screen) Output devices - 14-inch screen - Headphone jack and built-in speakers What I'd buy for my Something Real My Something Real is a short video case study of a local Centra for my Work Experience report. The built-in webcam is low resolution and the mic picks up background noise, so I'd buy: - A basic USB microphone (around €40), because voice clarity matters more than video quality for a case study - An external 1 TB SSD (around €80), because video files fill a 256 GB laptop fast Why not the cheap option: phone recording is fine for audio, but shaky handheld video looks unprofessional for a Work Experience deliverable that an employer might keep.

Chromebooks, laptops, and PCs are crucial tools for coding and digital skills education. Chromebooks are ideal for web-based applications and collaborative projects, while laptops and PCs support a wider range of programming environments and software for more intensive tasks like software development and data analysis.
