What is the difference between opcode and assembly language?

Assembly language, or just assembly, is a low-level programming language, which uses mnemonics, instructions and operands to represent machine code. Opcodes and Operands. An opcode is short for 'Operation Code'. An opcode is a single instruction that can be executed by the CPU.

What are opcodes and mnemonics in assembly language?

What this means is that each instruction in assembly language, which we call a ‘mnemonic’ represents a binary instruction, which we call an ‘opcode’, and you can see the opcodes and mnemonics in the list of x86 instructions I gave you above. Let’s take the CALL instruction for example. The opcode/mnemonic list is shown as:

What is an opcode in computing?

In computing, an opcode (abbreviated from operation code) is the portion of a machine language instruction that specifies the operation to be performed. Beside the opcode itself, instructions usually specify the data they will process, in form of operands.

What is the structure and arrangement of an opcode table?

The structure and arrangement of an opcode table appears as follows: Each cell from 00-FF contains information about the operation such as the equivalent assembly instruction corresponding to the opcode, parameters, and CPU cycle counts.
