Discuss how the speed of storage devices and memory is defined.

What will be an ideal response?

Student responses will vary, but should be drawn from the following information from the text.

When you turn on a computer or mobile device, it locates the operating system on its storage medium and loads the operating system into its memory (specifically, RAM). When you issue a command to run an application, such as a browser, the operating system locates the application on a storage medium and loads it into memory (RAM). When you are finished using the application, the operating system removes it from RAM, but the application remains on the storage medium. A storage medium is similar to a filing cabinet that holds file folders, and memory is similar to the top of your desk. When you want to work with a file, you remove it from the filing cabinet (storage medium) and place it on your desk (memory). When you are finished with the file, you remove it from your desk (memory) and return it to the filing cabinet (storage medium).
