WorksheetsUnderstanding CPU Performance Factors
Total questions: 10
Worksheet time: 5mins
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
