- 1Arithmetic logic unit (ALU)The ALU carries out calculations and makes decisions on the data sent to the processor.
- 2Control unit (CU)The CU, which is also called the controller, controls data moving through the processor, and controls the timing of operations and the instructions sent to the processor and the peripheral devices. The CU directs the system to carry out program instructions. It does the fetching, decoding, and managing of instructions.
- 3RegistersRegisters are also called internal memory or immediate access memory stores. A register is a small amount of fast temporary memory within the processor where the ALU or the CU can store and change values needed to execute instructions.
- 4high-level programming languages.High-level languages need to be translated into a binary code before the CPU can execute them. The benefit of high-level languages is that they are more like everyday written language than sequences of binary numbers, so people find them easier to write and understand.
- 5TranslatorsA piece of translator software, which is usually included within programming software, converts high-level languages into machine code. These translators are known as compilers and interpreters. Programs are translated using either a compiler or interpreter.
- 6CompilerA compiler translates a human-readable program directly into an executable, machine-readable form before the program can run.
- 7InterpreterAn interpreter translates a human-readable program into an executable, machine-readable form, instruction by instruction. It then executes each translated instruction before moving on to the next one. A program is translated every time it is run. Python is an example of an interpreted language.
