None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
CPU speed is primarily measured in Hertz (Hz), and Gigahertz (GHz) for modern processors
The fundamental unit is Hertz (Hz), where 1 Hz = 1 cycle per second.
Modern Units: Most, if not all, modern processors use Gigahertz (GHz), where 1 GHz = 10^9 Hz (one billion cycles per second).
Context: It is often referred to as the "clock speed" or "clock rate" of the CPU.
Mbps measures internet speed .
Mbytes measure data size .
