During a computer science class, Michael asked, 'What does the CPU stand for?'

• Central Processing Unit

• Central Programming Unit

• Central Performance Unit

• Central Peripheral Unit

In a classroom project, Jacob and Holly are building a model of a CPU. Which component of the CPU manages its components?

• Control Unit

• Arithmetic and Logic Unit

• Memory Address Register

• Memory Data Register

Kyan and Michael are working on a project. What is the function of the Arithmetic and Logic Unit (ALU) in their computer?

• Carries out basic mathematics and comparisons

• Manages the components of the CPU

• Stores the address of the next instruction

• Stores the data fetched from the main memory

Oskar and Jacob are discussing how a CPU works. What is the purpose of the Cache in a CPU?

• Stores commonly used data and instructions

• Stores the address of the next instruction

• Records the current instruction being executed

• Stores the results of calculations

During a computer science class, Freeborn asked, 'What does the Memory Address Register (MAR) store?'

• The address of the next instruction

• The data fetched from the main memory

• The current instruction being executed

• The results of calculations

Mohamed and Abigail are working on a computer science project. Mohamed asks Abigail, 'What is the function of the Memory Data Register (MDR)?'

• Stores the data fetched from the main memory

• Stores the address of the next instruction

• Records the current instruction being executed

• Stores the results of calculations

Ali is programming a robot to navigate a maze. What does the Program Counter do in this context?

• Records the current instruction being executed

• Stores the address of the next instruction

• Stores the data fetched from the main memory

• Carries out basic mathematics and comparisons

Michael is learning about the CPU in his computer science class. What is the role of the Accumulator in a CPU?

• Stores the results of calculations

• Stores the address of the next instruction

• Records the current instruction being executed

• Stores the data fetched from the main memory

Jenny and Mohamed are discussing what Clock Speed measures in a CPU. What is the correct answer?

• The number of fetch-decode-execute cycles per second

• The amount of data stored in the cache

• The number of cores in the CPU

• The size of the memory address register

Oskar and Michael are discussing different types of computers. What is an Embedded System?

• A special purpose computer built into another device

• A processing unit within a CPU

• A register that records the current instruction being executed

• A super fast memory located next to the CPU
