Computer Science Quiz

What is the main benefit of decomposition in problem-solving?

• It reduces the complexity of the problem.

• It removes all errors from a program.

• It ensures faster execution of code.

• It eliminates the need for abstraction.

What does abstraction focus on in problem modeling?

• Removing unnecessary details.

• Increasing computational speed.

• Storing data in RAM.

• Providing low-level hardware control.

Which concept is fundamental to the von Neumann architecture?

• Programs and data are stored together in main memory.

• Programs are hardwired into the CPU.

• Instructions are executed in parallel.

• Data is stored only in secondary storage.

What is the primary role of the control unit in the CPU?

• To perform calculations and comparisons.
