Steps involved in the fetch/ decode/ execute cycle:

The program is the set of rules stored in the memory. CPU (Central Processing Unit) is engaged when a computer runs a program that is officially called as fetch/decode/execute cycle.

Fetch:

The next instruction is fetched by the control unit from the main memory and it is stored in the instruction register.

Finally, at the end of fetch operation, PC (Program Counter) points to the next instruction that will be read at the decode cycle.

Decode:

The next operation in the instruction cycle is decoding operation, which is performed...
