When ever the central processing unit or the CPU gets the commands from main memory to carry out a particular process, the phase of time it takes to recover the instruction and set off the task is adverted to as the instruction cycle and might also be known as the I-cycle or the I-time.

The execution series also can be explained as the time duration or period in which the given command is executed and then the end result is just saved in a register and it might also be known as the E-cycle or the E-time. A machine cycle is composed of the instruction cycle in addition to one or more execution cycles. A machine cycle used to be calculated in milliseconds (thousandths of a second). But with the initiation of forever quicker central processing unit, we at the present are more expected to calculate machine cycles in microseconds and also in the nanoseconds or the picoseconds in the biggest and best ever computers.

The central processing unit has an internal clock that syncs all of the procedures and processes in the cycle and the clock speed aids or assists to decide the speed at which the processes are carried out.

Thank you very much! Yours is the only explanation I could even get close to understanding, and I understood it perfectly.
