The clock rate of the first generation of computers was measured in hertz or kilohertz kHzbut in the 21st century the speed of modern CPUs is commonly advertised in gigahertz GHz. This metric is most useful when comparing processors within the same family, holding constant other features that may impact performance. A multi-core processor is a single computing component with two or more independent actual processing units called "cores"which are the units that read and execute program instructions. The instructions[…]
