Learn the skill

Ordinary computer RAM holds information in use and normally needs power to retain it. Storage such as an SSD keeps saved files without continuous power. Editing is not saving. Real applications may autosave; this exercise explicitly does not.

Worked example

A saved story has 100 words. You add 20 in an editor with autosave off. Until saving, the saved file still has 100 words even if the screen shows 120.

Saved file before editing: 4 stars. Working copy after editing: 7 stars. Saved file after successful save: 7 stars. Autosave is off. — A working copy and its saved file can differ.

No-Autosave Sketchbook

A saved drawing has 4 stars. A student opens it and adds 3. Autosave and recovery are off in this simplified model. Before saving, the working copy has 7 stars but the saved file has 4. After a successful save, the stored file has 7. Do not switch off real equipment to test this story.

Question 1 How many stars are in the working copy after editing? Answer

Question 2 Before saving, how many stars are in the saved file? Answer

Question 3 After a successful save, how many stars are in that file? Answer

Question 4 Which statement matches ordinary RAM? It holds information in use and normally needs power It is always permanent storage It is a speaker

Question 5 Why does the story state that autosave is off? Autosave changes the number 4 Applications can save edits automatically RAM always saves every file
