There are several parts that interact with each other but ultimately the central has the end say of how it is handled - of course each company has their own design but these are just the basics - most of them when you look at the motherboard you will be able to find the processor - but you need to look close because they may have put in another to back it up. I have seen some systems where they have put in several for backup purposes - but this was years ago and with the micro-processors it is usually not needed - they have gotten somewhat better
this is called a central processing unit
the Fetch-Execute cycle is the process by which a computer retrieves a programmed instruction from its memory, determines what actions the instruction dictates, and carries out those actions.

Embedded processor is a part of the computer that follows instructions and carries out action.It is like the "brain" of a computer.
The only part of a program a computer understands is each instruction as it is presented to the instruction decoder. It understands the instruction by an intricately designed logic circuit and/or microprogram configured by a human computer hardware engineer. This engineer had to fully understand the instruction set of the machine to teach it to understand the instructions one at a time at runtime.
The CPU (Central Processing Unit) is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions. It is the unit that reads and executes program instructions. The data in the instruction tells the processor what to do.
A computer instruction is a command given to the computer to perform an operation.There are three instruction code formates.Memory - reference instructionRegister - reference instructionInput - output instructionIf you mean "Computer Instruction" as a field of study, then that is learning how to use computers.
The instruction unit (decodes and sends commands to alu of the cpu)
In programming, an instruction that directs the computer to another part of the program based on the results of a compare.

The instruction register holds a pointer to the current instruction (in working memory) while the next instruction register points to the next instruction (the first instruction immediately after the current instruction's operands). If the current instruction is a jump instruction, it can change the next instruction register, allowing the program to branch to a new instruction once the jump instruction is processed. The next instruction pointer is automatically moved into the current instruction register once the current instruction has been processed. The entire process of executing an instruction is known as the fetch-decode-execute cycle.
