• D) Watts

What is the relationship between the clock speed and the performance of a CPU?

• A) The higher the clock speed, the faster the CPU

• B) The lower the clock speed, the faster the CPU

• C) The clock speed has no effect on the CPU performance

• D) The clock speed depends on the CPU performance

What is an embedded system?

• A) A system that is embedded in another system

• B) A system that consists of a microprocessor and software

• C) A system that performs a specific function as part of a larger system
