9618 Chapt_4: Processor Fundamentals

What is the basic model for a computer system proposed by John Von Neumann?

• Quantum computing model

• Distributed computing model

• Parallel processing model

• Stored-program digital computer

Which unit is responsible for arithmetic and logic processing in a CPU?

• Program Counter (PC)

• Arithmetic and Logic Unit (ALU)

• Memory Data Register (MDR)

• Control Unit

What does the Control Unit manage in a computer system?

• Arithmetic calculations

• Moving data in and out of memory

• Input/Output operations

• Data storage

Which of the following is NOT a type of register?

• Program Counter (PC)

• Memory Address Register (MAR)

• Accumulator

• Data Bus

What is the purpose of the Fetch-Execute cycle?

• To store data permanently

• To process instructions from memory

• To manage input/output devices

• To increase clock speed

What does the term 'bus width' refer to?

• The speed of the system clock

• The number of instructions a CPU can execute

• The number of wires in a data bus

• The size of the CPU cache

Which type of interrupt is triggered by hardware devices?

• Software interrupt

• Timer interrupt

• External interrupt

• Internal interrupt

What is the role of the Memory Data Register (MDR)?

• To manage the flow of data between CPU and memory

• To execute arithmetic operations

• To temporarily hold data fetched from memory

• To hold the address of the next instruction

Which of the following is a characteristic of the Von Neumann architecture?

• Uses multiple processors

• Requires separate memory for data and instructions

• Processes instructions in parallel

• Data and programs are stored in the same memory

What does the term 'clock speed' measure?

• The number of cycles per second performed by the CPU

• The number of cores in a processor

• The amount of cache memory

• The width of the data bus
