Differences of Opcode and Bytecode
Opcodes and Operands. An opcode is short for 'Operation Code'. An opcode is a single instruction that can be executed by the CPU. In machine language it is a binary or hexadecimal value such as 'B6' loaded into the instruction register. In assembly language mnemonic form an opcode is a command such as MOV or ADD or JMPDifference between: Opcode, byte code, mnemonics, machine code and assembly. I am quite new to this. ... Generally, a mnemonic is a symbolic name for a single executable machine language instruction (an opcode), and there is at least one opcode mnemonic defined for each machine language instruction.Object code is in a form that only the OS on which it was compiled can interpret. The C compiler outputs object code for the OS that it was written for. The Java compiler puts out byte code that runs on its JVM(Java Virtual Machine). ... So as long as your OS has a JVM, you can run Java bytecode on it without recompiling.By using this approach, source code can be run on any platform once it has been compiled and run through the virtual machine. Bytecode is the compiled format for Java programs. Once a Java program has been converted to bytecode, it can be transferred across a network and executed by Java Virtual Machine (JVM).
