- 1OpcodeThe opcode tells the processor the job that needs to be done. A simple operation could be add or subtract.
- 2OperandThe operand specifies the data that needs to be acted on. The operand can also refer to a place in memory.
- 3InstructionsMost programmers do not write programs as sequences of binary digits. They use programming languages like Java, C++, Ruby, BASIC or Python.
- 4TranslatorsA piece of translator software, which is usually included within programming software, converts high-level languages into machine code.
- 5Assembly languageAssembly language is a low-level language which closely reflects how opcodes and operands work
- 6Assembly codeAssembly language instructions use abbreviations called mnemonics they are easier to understand than machine code to humans.
- 7Fetch-decode-execute cycleThe main job of the CPU is to execute programs using the fetch-decode-execute cycle (also known as the instruction cycle). This cycle begins as soon as you turn on a computer to the moment it is turned off.
- 8Human readable languageHuman-readable language instructions are encoded in a language that humans can understand more easily.
- 9machine readable languageMachine-readable language instructions are written using only binary codes
- 10CompilerA compiler translates a human-readable program directly into an executable, machine-readable form before the program can run.
