Study Notes

Java SIBA Syllabus - Programming Terminology

  • Source Code: A set of instructions written in a human-readable programming language, understood by programmers, but not directly by computers. It needs translation.
  • Machine Code: The code that can be directly executed by a computer.
  • Compiler: Translates the entire high-level source code into machine code at once.
  • Interpreter: Translates and executes high-level language code line by line.
  • Advantages of using an Interpreter: Faster error detection with diagnostic messages, smaller program size, and better efficiency at execution speed.
  • Advantages of using a Compiler: Optimized execution speed compared to interpreters. More efficient use of computer memory.
  • Translator (in programming): Converts source code to machine code.
  • Object Code: The output of a compiler stage, an intermediate representation of source code that can be executed by a virtual machine.
  • Executable Code:The final output from the compilation process, ready to run on the computer.
  • Byte Code: Another name for object code.
  • Compiled programs: Characteristics include slower translation speeds to interpreted programs.
  • Interpreted programs: Executed line by line
  • Late Binding: A characteristic of an interpreter, decisions about program implementation until runtime
  • File extension for executables: .exe
  • Languages often used for source code: Python
  • Why source code needs conversion: Computers can't directly understand human-readable source code. Needs to be converted into machine code for execution.
