What is the clock cycle and clock frequency?

I read a book about a computer processor. And I stumbled upon some of the terms Clock Ticks, Clock Cycle and Clock Speed ​​which I find very difficult to understand. I will be very grateful if someone can clarify this in simple language. Thanks in advance!

A sync cycle is the speed of a computer processor or processor and is determined by the clock cycle, which is the amount of time between two oscillator pulses. Generally speaking, the higher the number of pulses per second, the faster the computer processor can process information. Clock speed is measured in Hz, usually either megahertz (MHz) or gigahertz (GHz). For example, a 4 GHz processor performs 4,000,000,000 cycles per second. Computer processors can execute one or more instructions per clock cycle, depending on the type of processor. Early computer processors and slower processors could only execute one instruction per cycle, but faster, more advanced processors can execute multiple instructions per cycle, processing data more efficiently.



On the other hand, Clock Speed ​​(sometimes called clock speed) refers to the number of pulses per second generated by a generator that sets the tempo for the processor. Clock rates are usually measured in MHz (megahertz, or millions of pulses per second) or GHz (gigahertz, or billions of pulses per second). Today, personal computers run at hundreds of megahertz, and some exceed one gigahertz. The clock frequency is determined by a quartz crystal circuit similar to that used in radio communications equipment.
