What is the name given to a computer processing speed measured in?

The processing speed of a computer is commonly measured in hertz, which reflects the number of cycles per second that a processor can perform. Specifically, gigahertz is defined as one billion cycles per second, making it a standard unit for measuring modern processors' speeds. As technology has advanced, processors have increasingly operated at speeds measured in gigahertz, providing better performance and processing power for various applications.

While megahertz, which represents one million cycles per second, was once a common measurement for earlier CPUs, gigahertz has taken precedence for current technology. Megabytes and terabytes, on the other hand, are units related to data storage rather than processing speed, indicating the volume of data that can be stored or processed. Thus, gigahertz is the most appropriate answer for measuring computer processing speeds today.
