MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A CPU which completes three billion clock cycles per second has a clock speed of 3 GHz.

Detailed explanation-2: -One gigahertz represents 1 billion cycles per second.

Detailed explanation-3: -A 3.0 GHz processor has 3 billion opportunities per second to do something, while a 3.6 GHz processor has 3.6 billion chances–making it roughly 20 percent faster.

Detailed explanation-4: -A CPU with a clock speed of 3.2 GHz executes 3.2 billion cycles per second. (Older CPUs had speeds measured in megahertz, or millions of cycles per second.) Sometimes, multiple instructions are completed in a single clock cycle; in other cases, one instruction might be handled over multiple clock cycles.
