RAM and persistent storage both hold data, but they support different parts of a computer’s work. RAM provides working space for active processes. Persistent storage keeps files and applications when power is removed. When an application opens a document, it loads information into working memory and may create temporary data. Saving writes the intended changes to persistent storage. More RAM can help with some workloads, but it does not automatically make every task faster or increase the space available for saved photos. A device can have free storage and still struggle with many demanding applications. It can also have adequate RAM but insufficient storage for a new file. Performance depends on several components and the workload. Unsaved changes may be lost when an application stops unexpectedly. Practice: Classify three examples: an open document being edited, a saved photo, and an installed application. Explain which data must be saved to survive closing the program.
