|How is that possible and what is the reason behind this?|
|Niveditha said: (Feb 13, 2011)|
|What is the explanation? please post it.|
|Vijay said: (Feb 19, 2011)|
|You can see that in the given options only operation code is capable of conducting some operation that too at machine level.
I hope you are satisfied with my answer.

|What is the explaination post it.|

|Operation code only says about the operations performed in micro processor.|
|Robin said: (Sep 13, 2011)|
|Operation code is right answer.|
|Jan said: (Oct 15, 2011)|
|An instruction includes an opcode specifying the operation to be performed, such as "add contents of memory to register", and zero or more operand specifiers, such as registers, memory address or physical data.|
|Hitesh said: (Mar 9, 2012)|
|Operation code is the better answer.|
|Shaharyary Qureshi said: (Apr 26, 2012)|
|Operations code are used in assembly language to instruct the MP that which instruction is going to excute.|
|Abhijit Sahoo said: (May 22, 2012)|
CPU has ALU (arithmatic and logic unit) for performing many arithmatic and logical operations and CU (control unit) for sending control signal to tell ALU about which operation to be performed.
As we have many operation to be performed by the same hardware unit of ALU, so we should have different binary equivalent code to identify each operation and that binary code is called opcode.
Control unit decode the opcode and issue corresponding control signal to perform appropriate operation between operands.
|Ritesh Bora said: (May 30, 2012)|
|Operational code is right beacause muchine instruction has two part a) operational code b) operands i.e. address in that address tell about location of operands and operational code tells about what to perform on operands.
I hope you got it.
|Ansh said: (Sep 29, 2012)|
|Address is right because for execution of instruction that have to converted into binary codes.|
|Narendra534 said: (Nov 22, 2012)|
|The machine can understand only the OP-CODES like ADD, MUL, SUB, DIV, SUM etc. So the OP-CODE (operation code) tells the CPU to perform the kind of operations like ADD, MUL, DIV, SUB, .|
|Nisha said: (Sep 26, 2013)|
|Whenever a process executed by ALU now it check the process id provided by operating system which helps to identify the required process by processor, the operation is to be performed.|
|Lucky said: (Dec 28, 2013)|
|What are flip flops?|
|Rahul Ranjan said: (Feb 24, 2014)|
|The Operation Is The Machine Level Programming, That Are Predefined Or Fixed, WE Can Implement only No one Can Change It.|
|Rupesh said: (Feb 27, 2014)|
|The processors job is to process the information right. So the address it cannot process so it has to process only the data. So the data is residing in opcode. As you all are familiar with 8051 instructions.|
|Aman said: (Apr 10, 2014)|
|Answer to the question of @Lucky.
Flip flops are small storage cells which can store one bit of information at a time. They are further used in " registers" too.
There are too many types like SR flip flop. D flip flop, T flip flop etc.

|What was the right answer?|
|Chetan said: (Jun 30, 2014)|
|Operation code is right answer.|
|Vasu said: (Aug 12, 2014)|
|Micro process take operation code based on the user request and it's take value instruction binary conversion.

|Dave said: (Oct 7, 2015)|
|Operation code instruct processor to perform to operation.|
|Vinay said: (Dec 3, 2015)|
|Gali Bhargav Reddy said: (Jul 11, 2016)|
ADD A, B.
Here ADD is an OPERATIONAL CODE (OP CODE) which performs addition of A and B and this is an INSTRUCTION to the PROCESSOR to do.
|Manoj Kumar said: (Sep 7, 2017)|
|Operation code is correct answer.|
|Tanvi said: (Jun 2, 2018)|
|Yes, as an instruction has two parts, opcode and operands out of which opcode is the operation code which operates on the operands.|
|Esiyas said: (Nov 24, 2018)|
|The answer is the operation code. Because it is a machine level code that is controlled by a control unit which controls the operations of the central processor.|
|Harun Danish said: (Feb 5, 2019)|
|What is explanation this question will problem?|
|Harish Margam said: (Apr 5, 2019)|
|This is opcode so opcode is understanding machine language.|
