– The speed of a computer processor, or CPU, is determined by the clock cycle, which is the amount of time between two pulses of an oscillator. Higher the number – higher the speed – faster the CPU.
– Computer processors can execute one or more instructions per clock cycle, depending on the type of processor.

In software engineering and computer science, abstraction is a technique for arranging complexity of computer systems. It works by establishing a level of complexity on which a person interacts with the system, suppressing the more complex details below the current level.
