What is clock speed?
A
fast access memory on the CPU
B
The time that the instruction was read
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -A clock speed of 3.5 GHz to 4.0 GHz is generally considered a good clock speed for gaming but it’s more important to have good single-thread performance. This means that your CPU does a good job of understanding and completing single tasks. This is not to be confused with having a single-core processor.

Detailed explanation-2: -One of them is clock speed. This determines how fast the RAM processor your data. The clock speed of extra RAM has to be the same as that of your current RAM. With a new PC, the maximum clock speed is determined by the motherboard.

Detailed explanation-3: -Why Does Clock Speed Matter? CPU clock speed is a good indicator of overall processor performance. Though applications like video editing and streaming are known to rely on multi-core performance, many new video games still benchmark best on CPUs with the highest clock speed.

Detailed explanation-4: -In a computer, clock speed refers to the number of pulses per second generated by an oscillator that sets the tempo for the processor. Clock speed is usually measured in MHz (megahertz, or millions of pulses per second) or GHz (gigahertz, or billions of pulses per second).

Detailed explanation-5: -Clock speed CPU clocks can sometimes be sped up slightly by the user. This process is known as overclocking. The more pulses per second, the more fetch-decode-execute cycles that can be performed and the more instructions that are processed in a given space of time.
