Understanding CPU Performance Factors

What does the clock speed of a CPU measure?

• The amount of data it can store

• The size of its cache

• The number of cores it has

• The number of cycles it can perform per second

What is the purpose of cache in a CPU?

• To increase the number of cores

• To reduce the clock speed

• To store temporary data and instructions

• To permanently store data

What is a core in the context of CPU architecture?

• A complete copy of a CPU

• A unit measuring the cache size

• A type of clock speed

• A temporary storage area

Why doesn't doubling the number of cores necessarily double the processing speed?

• Most programs can use multiple cores effectively

• Doubling cores reduces the cache size

• Cores do not need to communicate

• Cores need to communicate, which takes time

What is the effect of a larger cache size in a CPU?

• It decreases the clock speed

• It slows down the processing speed

• It reduces the need to fetch data from memory frequently

• It increases the number of cores

Which component of the von Neumann architecture is responsible for executing instructions?

• Memory Unit

• Control Unit

• Arithmetic Logic Unit (ALU)

• Input/Output Devices

In von Neumann architecture, what is the role of the control unit?

• Storing data permanently

• Performing arithmetic operations

• Managing the flow of data and instructions

• Connecting to external networks

Which technology is primarily used for archival data storage?

• SSD

• NVMe

• HDD

• Magnetic tapes

What is the primary purpose of data compression in computer systems?

• To increase the processing speed

• To reduce the size of data for storage and transmission

• To enhance the security of data

• To increase data redundancy

Which compression method does not lose any data during the process?

• Lossy compression

• Lossless compression

• Variable compression

• Adaptive compression
