Jacob has a text file open, and he is typing on the keyboard. What is the best description of how the changes are being implemented?

Question

a. The original file is temporarily changed; the changes become permanent when he clicks “save.”

b. The new version is kept in a special virtual space; the file is only changed when he clicks “save.”

c. The information is stored on the clipboard.

d. A copy is created with a new filename, which will overwrite the old one when he clicks “save.”

Answer 1

The best description of how the changes are being implemented is:

b. The new version is kept in a special virtual space; the file is only changed when he clicks “save.”

This explains that while Jacob is typing, the changes are held in memory (often referred to as a "buffer") and are not written to the actual file until he selects to save the document.
