Answer:
PDF
Step-by-step explanation:
The Portable Document File (PDF) can be opened on many computers that have a good running windows. The PDF format, is known as the adobe document, chiefly because it is powered and driven by the adobe reader software. The software saves the file with all the formatting so that it cannot be altered when opened with another computer.
A good example is the file numbers and symbols in word that cannot be opened or displayed correctly on a Mac book. In this case, the PDF saves the original symbol format.
