Factors Affecting CPU Performance

What are the factors affecting the speed of a racing car?

• Horsepower, weather conditions, driver's skill, aerodynamics

• Clock speed, number of cores, cache size, instructions

• Tyres, weather conditions, driver's skill, aerodynamics

• Clock speed, cache size, number of cores, instructions

What is clock speed measured in?

• Instructions per second

• Operations per second

• Hertz

• Gigahertz

What is the purpose of the cache in a CPU?

• To store temporary storage of instructions and data

• To store the main memory

• To store the CPU cores

• To store the clock speed

What is the tipping point in terms of cache size?

• When the cache size is equal to the main memory size

• When the cache size is smaller than the main memory size

• When the cache size is larger than the main memory size

• When the cache size is zero

What is a CPU core?

• A temporary storage of instructions and data

• A complete copy of a CPU

• A specialized processor for graphics and sound

• A communication unit between CPU cores

What is the disadvantage of having multiple CPU cores?

• Increased efficiency and performance

• Decreased communication and synchronization

• Limited storage capacity

• Incompatibility with programs

What is a chip multiprocessor?

• A single physical chip with multiple CPU cores

• A specialized processor for graphics and sound

• A temporary storage of instructions and data

• A communication unit between CPU cores

How can the overall performance of the main CPU be improved?

• By increasing the clock speed

• By offloading tasks to specialized processors

• By increasing the cache size

• By adding more CPU cores

What are separate graphics cards and sound cards?

• Highly specialized forms of the main CPU

• Temporary storage of instructions and data

• Separate CPUs for graphics and sound

• Communication units between CPU cores

What is the benefit of offloading tasks to specialized processors?

• Decreased overall performance

• Increased efficiency of the main CPU

• Limited storage capacity

• Incompatibility with programs
