Year 8 - CPU and Von Neumann Architecture

What does CPU stand for?

• Central Processing Unit
• Central Protecting Unit
• Central Processing Units
• Core Processing Unit

Select the correct CPU cycle:

• Execute -> Decode -> Fetch
• Fetch -> Execute -> Decode
• Decode -> Fetch -> Execute
• Fetch -> Decode -> Execute

What are the three main components of a CPU?

• Hardware, Software, Memory
• Memory, Control, ALU
• ALU, Memory Unit, Control Unit
• Fetch, Decode, Execute

What is the purpose of an Operating System?

• stores the user's application data
• provides interface for hardware to use
• operates the computer system
• provides interface for software to use

Which of the following affects the performance of a CPU?

• Number of cores
• Hard Drive capacity
• Number of applications stored
• Number of Hard Drives used

A single core has a clock speed of 1.8 GHz. How many instructions per second can the quad core version process?

• 6.2 billion
• 7.2 billion
• 8.2 billion
• 7.6 billion

What is the purpose of the Control Unit in Von Neumann architecture?

• save data onto memory
• manage process of moving data in and out of memory
• controls the hardware components
• controls the software

What is the purpose of using the ALU?

• performing calculations on data
• controlling calculations on data
• controlling the speed of calculations
• save memory onto hard drive

What is the purpose of a 'Bus' in a computer system?

• Carry data to and from internal components
• execute user's instructions
• control flow of data
• connects the CPU to motherboard

Why can dual core processors be considered better than single core?

• Faster speed 
• More instructions carried out per second
• Two instructions can be run in parallel
• double the processing power
