Question

1. why is an operating system required for computers to function properly?

it is the foundation, or platform, needed for the motherboard.
it understands binary language and puts the information into a form the user can understand.
it is not necessary for the computer to run properly; it just makes it more convenient.
it speeds up the computer to allow it to work much faster.

1. what is the difference between save and save as?

both do the same thing; however, save is also a quick save for previously saved documents.
save is temporary, and save as is permanent.
save sends the file to a flash drive, and save as sends the file to the hard disk.
there is no difference.

Explanation:

For question 9:

• The motherboard has its own firmware (BIOS/UEFI). The operating system is not its foundation.
• An operating system is necessary for a computer to run properly, not just for convenience.
• It doesn't directly speed up the computer's hardware. But it acts as an intermediary. It takes user - level commands (in a human - understandable form like a graphical interface or text commands) and translates them into binary (machine - understandable code) for the computer's hardware.

For question 10:

• “Save As” is used to create a new file (either with a new name, location, or format), while “Save” updates the existing file (if it was previously saved). So they are not the same.
• “Save” is not temporary. Both can be permanent depending on the storage medium.
• The difference is not about the storage device (flash drive vs hard disk). “Save As” gives more options like renaming, changing format etc.

Answer:

1. B. It understands binary language and puts the information into a form the user can understand.
2. A. Both do the same thing; however, Save is also a quick save for previously saved documents.
