Question

1. the operating system handles file management and what else?

printing documents
selecting color of text
spell checking
inserting graphics

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

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 is the foundation, or platform, needed for the motherboard.
it speeds up the computer to allow it to work much faster.

Explanation:

For question 15:

• The operating system is responsible for managing system resources. Printing documents is a system - level task that the operating system can handle (e.g., spooling print jobs).
• Selecting the color of text, spell - checking, and inserting graphics are typically functions of application software (like word - processing software), not the operating system.

For question 16:

• The operating system acts as an intermediary between the computer hardware (which understands binary) and the user. It takes user commands (in a more human - understandable form) and translates them into binary for the computer to execute, and vice - versa (converting computer output from binary to a user - understandable form).
• Option 2 is incorrect because the operating system is necessary for a computer to function properly (e.g., managing memory, processes). Option 3 is wrong as the motherboard has its own firmware (BIOS/UEFI), and the operating system is not the foundation for the motherboard. Option 4 is incorrect as the operating system does not directly speed up the computer's hardware in the way described; it manages resources but not in a "speed - up" sense as stated.

Answer:

1. printing documents
2. It understands binary language and puts the information into a form the user can understand.
