3.1.1: The CPU (Edexcel GCSE Computer Science)

In Von Neumann architecture, where are programs and data stored?

• In separate memories

• In the same memory

• In the cloud

• On external drives

What is the key idea of the Von Neumann architecture called?

• Cloud computing

• Distributed processing

• Stored program concept

• Parallel processing

What is one advantage of storing programs and data in the same memory?

• It makes computers slower

• It makes computers more expensive

• It makes computers simpler and cheaper

• It requires more memory types

What is a benefit of using the same space for both data and instructions?

• It makes the computer less efficient

• It helps run different tasks easily

• It requires more hardware

• It limits the computer's capabilities

Which component in Von Neumann Architecture acts as pathways for data?

• Main Memory (RAM)

• CPU

• Buses

• Clock

What does the Control Unit (CU) do within the CPU?

• Performs mathematical calculations

• Directs the flow of data

• Stores data temporarily

• Carries out logical operations

Which component of the CPU tells the computer's memory and devices how to respond to instructions?

• Registers

• Arithmetic Logic Unit (ALU)

• Control Unit (CU)

• Hard Drive

Which of the following statements is true about CPU clocks?

• They only synchronize input/output operations

• They are not related to the FDE cycle

• They synchronize all actions in the CPU

• They only affect memory access speed

What happens when the clock speed is increased?

• The CPU processes fewer instructions

• The CPU generates less heat

• The CPU processes more instructions

• The CPU uses less power

Which type of bus sends control signals to coordinate operations?

• Address Bus

• Data Bus

• Control Bus

• Signal Bus
