Short Answer Questions 10×2=20

1 Define “system.”

ii What role do components play in a system?

System → Components → Interactions → Output

iii Describe the interaction between a computer and a printer.

iv What are the main components of the Von Neumann architecture?

Input

CPU

Memory

Output

v List the stages of the empirical cycle.

vi How do natural scientists validate their theories?

vii Why is computer science considered both theoretical and practical?

viii List the four main components of Von Neumann architecture.

ix What is the role of the ALU?

x Differentiate between the address bus and control bus.

Hint: Address bus carries memory addresses while control bus carries control signals

Detailed Answer Questions (Answer any 2) 2×5=10

1 Explain the four basic concepts of a system (objectives, components, environment, communication).

Key Points: Objectives define purpose, components are parts, environment is context, communication enables interaction

2 Compare deterministic and non-deterministic environments with examples.

3 Analyze the advantages and disadvantages of Von Neumann architecture.

Consider: Simplicity vs. bottleneck, flexibility vs. security, historical significance vs. modern limitations
