Detailed explanation-1: -Opcodes and operands The opcode is the instruction that is executed by the CPU and the operand is the data or memory location used to execute that instruction.
Detailed explanation-2: -In computing, an opcode (abbreviated from operation code, also known as instruction machine code, instruction code, instruction syllable, instruction parcel or opstring) is the portion of a machine language instruction that specifies the operation to be performed.
Detailed explanation-3: -The opcode supplies the instruction details to the processor, and the operand provides the necessary data. An operand might contain the data or an address for where the data can be found, such as a location in a register or in system memory.
Detailed explanation-4: -The opcode is the machinecode representation of the instruction mnemonic. Several related instructions can have the same opcode. The opcode field is 6 bits long (bit 26 to bit 31). The numeric representations of the source registers and the destination register.
