Explanation:

• Question 31: The power supply unit (PSU) in a computer is responsible for converting the alternating current (AC) from the wall outlet to the direct current (DC) that the computer components need. So, it provides the electricity needed for the computer to run.
• Question 32: A microprocessor is a CPU (Central Processing Unit) on a single chip that carries out instructions and handles computations. It is the "brain" of the computer or other electronic devices.
• Question 33: Embedded operating systems are designed for devices with specific functions. These devices have limited resources (like memory and processing power) compared to supercomputers, personal computers, or servers.
• Question 34: Microsoft Windows is known for its user - friendly interface and extensive software compatibility. It has a large market share, and many software developers create applications for the Windows platform.

Answer:

• 31. Provides the electricity needed for the computer to run
• 32. A CPU on a single chip that carries out instructions and handles computations
