7 what is the role of the power supply unit (psu) in a computer? stores data long - term processes data and information connects the computer to the internet provides the electricity needed for the computer to run 8 what is random access memory (ram)? volatile memory that stores data long - term non - volatile memory that stores data short - term non - volatile memory that allows data to be accessed in any order volatile memory that allows data to be accessed in any order 9 what is the function of cmos in a computer? processes data and information holds essential information for starting the computer connects the computer to the internet stores long - term data

Explanation:

• For question 7: The power supply unit (PSU) in a computer is responsible for providing the electricity required for the computer's components to operate.
• For question 8: Random - Access Memory (RAM) is volatile memory that allows data to be accessed in any order. When the power is turned off, the data in RAM is lost.
• For question 9: CMOS (Complementary Metal - Oxide - Semiconductor) in a computer holds essential information for starting the computer, such as system settings.

Answer:

1. Provides the electricity needed for the computer to run
2. Volatile memory that allows data to be accessed in any order
3. Holds essential information for starting the computer
