Highlighted significa destacadas, resaltadas; y Bold es lo que llamamos 'negrita', con las letras más gruesas...

Certainly! Do you have a Word program on your computer? If so, you know it is possible to change how certain words will be printed, for example, in italic letters. You can also make some words be printed in bold letters - such as the type used in the question above. When you do so, the words are "highlighted." If you still have questions, if I did not explain this clearly, please write.

I agree with sudsey
