WHAT IS A MOTHERBOARD

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
One measure of CPU performance is the number of cycles or instructions it can perform in a second-two examples of this measurement are ____
A
gigabytes, megabytes
B
hyperthreading
C
gigahertz, megahertz
D
multicore
Explanation: 

Detailed explanation-1: -The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz).

Detailed explanation-2: -With every tick of the clock, the CPU fetches and executes one instruction. The clock speed is measured in cycles per second, and one cycle per second is known as 1 hertz. This means that a CPU with a clock speed of 2 gigahertz (GHz) can carry out two thousand million (or two billion) cycles per second.

Detailed explanation-3: -GHz, short for gigahertz, is a unit of frequency equal to one billion hertz. It is commonly used to measure computer processing speed, alternating current, and electromagnetic (EM) frequencies.

Detailed explanation-4: -A CPU which completes three billion clock cycles per second has a clock speed of 3 GHz.
