    Unsaved work lives only in RAM and vanishes if power cuts. Saved work stays in permanent storage.

    Welcome

    Today you find out where your work actually lives when you close the lid, pull a USB stick, or the power cuts mid-sentence. That matters for every file in your Something Real project, from a Work Experience log to a small-enterprise budget.

    By the end of this lesson, you will be able to:

    • Explain the difference between RAM (working memory) and permanent storage
    • Compare local drives, USB, external drives and cloud storage for school work
    • Describe what happens to unsaved work when power is lost and why save-often matters
    • Save the same file to local, USB (or simulated) and cloud locations and evidence each save

    Warm-up

    Imagine you have typed half a page of your Project Brief and the computer suddenly restarts. What do you think is still there when it comes back on, and what is gone? Hold your answer. We will sort real cases in a few minutes.

    You need {{code:01_project_brief}} today. Project Portfolio is the folder in school cloud your teacher named (OneDrive or Google Drive). If you cannot see the folder or the file, tell your teacher before we move on. Do not invent a new brief unless the teacher asks you to.

    2 - Key Concepts ~8 mins

    Key point

    Power-cut rule: if you have not saved, the work is only in short-term working memory (RAM). A restart, crash, or power cut wipes it. Once you save, it lives in permanent storage and can still be there tomorrow. Save often while you work: autosave helps in cloud apps, but long gaps between saves still punish you if the machine dies.

    {{img:img_ram_vs_storage_concept}}

    Your teacher will walk the two rows below, then name the three homes for saved files. Listen first; you do not need to memorise every cell.

    ConceptWhy it mattersExample
    RAM (working memory) — short-term memory while programs are openUnsaved work vanishes if power is lost or the app crashesHalf a Work Experience reflection typed but never saved: gone after a restart
    Permanent storage — where files live after you save (disk, USB, cloud)Saved work survives shutdowns, so your portfolio is still there tomorrowYour {{code:01_project_brief}} in Project Portfolio after you pressed Save

    Three homes for saved files

    Once a file is saved, it still has to live somewhere. Your teacher will name these three buckets (you will sort cards into them next):

    • Local storage — on this machine only (Documents, Desktop, Downloads). Fast here, but not on another classroom PC unless you move it.
    • Portable storage — USB sticks and external drives you carry between machines that do not share the same cloud sign-in.
    • Cloud storage — online space in a browser after sign-in (the school cloud your teacher named). Same files from home or school once you sign in; needs a network to sync.

    Worked example: one file, three homes

    {{img:img_three_places_workflow}}

    Worked example

    Same Project Brief ({{code:01_project_brief}}) ends up in three places:

    1. Local — a copy in Documents on this PC
    2. Portable — a copy on a USB stick, or in a Desktop folder named {{code:USB_Simulated}}
    3. Cloud — the same file inside Project Portfolio on school cloud (OneDrive or Google Drive)

    Evidence goes in a new document called {{code:01_saved_in_three_places}}: three screenshots (filename visible each time) with one caption each, for example Local — Documents on this PC. You will build that proof after a short teacher demo.

    3 - Where Does It Live When the Power Goes? ~12 mins

    Sort each card into the place it actually lives. First talk it through as a class without dragging. Then place the cards and check.

    Common Issues

    Tip

    Keep this table handy during the Portfolio Build. Your teacher will leave it visible on the projector.

    IssueSolution
    I cannot find my {{code:01_project_brief}}Open your Project Portfolio folder in school cloud first. If it is only on this PC, check Documents and Desktop, and use the machine's search box with the filename. If it is still missing, tell your teacher and create a one-line stub before the three saves.
    The brief only opens in the browserIn Word Online or Google Docs use File → Download (for example as .docx). Save or move that download into Documents. Use the downloaded file for the USB or {{code:USB_Simulated}} copy too.
    There is no USB stick availableOn the Desktop, create a folder named {{code:USB_Simulated}}. Copy the file into that folder and treat it as portable storage for today's evidence.
    The USB stick does not appearUnplug and replug it. On Windows open File Explorer and look under This PC. On Mac open Finder and look in Locations. On a Chromebook look under Files → USB. Try another port if needed.
    I am not signed into school cloudOpen the cloud your teacher named: {{code:onedrive.com}} or {{code:drive.google.com}}. Sign in with your school account. Do not tick "remember me" on a shared school machine if your teacher has asked you not to.
    I do not know how to take a screenshotWindows: {{kbd:Win+Shift+S}} then paste with {{kbd:Ctrl+V}}. Mac: {{kbd:Cmd+Control+Shift+4}} (selection goes to the clipboard) then paste with {{kbd:Cmd+V}}. If you used {{kbd:Cmd+Shift+4}} by mistake, the image lands on the Desktop — drag or Insert that file into the evidence doc. Chromebook: {{kbd:Ctrl+Overview}} (Overview is the rectangle-with-lines key at the top; also labelled Show windows), or {{kbd:Ctrl+Shift+Overview}} for a region, then paste. The shot must show the filename {{code:01_project_brief}}.
    My cloud copy is missing after I uploadedRefresh the browser tab and open the Project Portfolio folder again. Confirm you uploaded into the folder, not only onto the cloud home page.

    5 - Portfolio Build ~22 mins

    Portfolio Build

    Your goal: Prove your Something Real Project Brief is safe in three different kinds of storage, so a power cut or a single broken stick cannot wipe out the start of your portfolio.
    Time: ~20 minutes after the teacher demo
    Task: Your teacher will demo once on the projector, then you build the three-place proof while they circulate.
    1. If you cannot see {{code:01_project_brief}}, tell the teacher before you start. Search Project Portfolio, Documents, and Desktop. Create a one-line stub only if the teacher agrees it is missing.
    2. Open {{code:01_project_brief}} from Project Portfolio. If it only opens in the browser (Word Online or Google Doc), download a copy first (File → Download, for example as .docx) and put that download into Documents on this machine. That downloaded file is your local copy.
    3. If you already have a real file on this PC, copy it into Documents instead (right-click → Copy, then Paste in Documents, or drag it in).
    4. Copy the same file onto a USB stick, or create a Desktop folder named {{code:USB_Simulated}} and copy it there. Use the downloaded or Documents file, not only the browser tab.
    5. Upload or save the same file into your Project Portfolio folder in the school cloud your teacher named (OneDrive or Google Drive). Confirm it sits inside the folder, not on the cloud home page.
    6. Take a screenshot of each of the three locations. Each shot must clearly show the filename {{code:01_project_brief}} in a different place (Documents path, USB or {{code:USB_Simulated}} folder, cloud Project Portfolio).
    7. Still inside Project Portfolio, create a new Word Online or Google Doc named {{code:01_saved_in_three_places}}. Paste the three screenshots. Under each image write one caption line naming the storage type and where it is (for example: Local — Documents on this PC).

    If a stick will not show or cloud asks you to sign in again, that is normal on school machines. Use the Common Issues table and the {{code:USB_Simulated}} folder rather than waiting. Open Need the clicks after the demo? below only if you are stuck after watching the demo.

    Success criteria:
    • {{code:01_project_brief}} is in local Documents on this machine.
    • The same file is on a USB stick or in {{code:USB_Simulated}}.
    • The same file is inside cloud Project Portfolio.
    • {{code:01_saved_in_three_places}} is in Project Portfolio with three screenshots.
    • Each screenshot is clear enough to read the filename {{code:01_project_brief}}.
    • Each screenshot has a one-line caption that names the storage type (local, portable, or cloud).
    Need the clicks after the demo? (only if you are stuck)

    Screenshot shortcuts

    • Windows: {{kbd:Win+Shift+S}}, then paste with {{kbd:Ctrl+V}}
    • Mac: {{kbd:Cmd+Control+Shift+4}} (selection to clipboard), then paste with {{kbd:Cmd+V}}. Fallback: {{kbd:Cmd+Shift+4}} saves to Desktop — Insert or drag that file into the evidence doc.
    • Chromebook: {{kbd:Ctrl+Overview}} (Overview is the rectangle-with-lines key; also labelled Show windows), or {{kbd:Ctrl+Shift+Overview}} for a region, then paste

    Every shot must show the filename {{code:01_project_brief}} in a different location UI.

    1. Local copy into Documents

    If the brief only opens in the browser, download first (Word Online or Google Docs: File → Download), then move the download into Documents. Use that file for portable copy too.

    • Windows: File Explorer → find the file → right-click → Copy → open Documents → right-click → Paste (or drag).
    • Mac: Finder → find the file → right-click → Copy → open Documents → right-click → Paste (or drag).
    • Chromebook: Files app → find the file → right-click → Copy → My files → Documents (or Downloads if that is your class local folder) → Paste.

    2. Portable: USB or {{code:USB_Simulated}}

    • USB — Windows: File Explorer → This PC → USB drive → paste or drag the file in.
    • USB — Mac: Finder → Locations → USB drive → paste or drag.
    • USB — Chromebook: Files → USB → paste or drag.
    • No stick (all machines): Desktop → new folder {{code:USB_Simulated}} → copy the file into it.

    3. Cloud into Project Portfolio

    • Go to {{code:onedrive.com}} or {{code:drive.google.com}} (the one your teacher named). Sign in with your school account.
    • Open Project Portfolio. Upload the file into that folder (Upload / New → File upload, or drag). Confirm the filename appears inside the folder.

    4. Evidence document

    • Inside Project Portfolio, create a Word Online or Google Doc named exactly {{code:01_saved_in_three_places}}.
    • Paste three screenshots. Caption each line, for example: Local — Documents on this PC · Portable — USB_Simulated on Desktop · Cloud — Project Portfolio.
    • Leave the document in Project Portfolio. It saves there automatically.
