Introduction of Programming Languages

An animation that shows a for loop compiled to binary

  • Purpose: Communicate instructions to a computer.
  • Overall
    • High-level languages: Easy for humans to read and write.
    • Low-level languages: Close to machine code, harder for humans to read but easier to control lower level details

  • High Level

    • Logo of the Java Programming Language

  • Low Level

    • Logo of the c programming language
    • Logo of the fourth programming language
Concepts in Computer Science

Functional, procedural, and low-level programming

  • Functional Programming
    • Mathematical functions (pure function - ex: tidy up desk)
    • Immutability (no side effects - ex: no changes in filing cabinet)
  • Procedural Programming
    • Sequence of commands (step by step instructions - ex: tidy up desk, move file to cabinet)
    • Immutable data (side effects - ex: new files in cabinet or sign document)
  • Low-level Programming
    • Access inner workings (hardware manipulation - ex: change office thermostat)
    • Immutable (side effects - ex: thermostat, spacing in file cabinet)
  • Examples
    • Functional: (Lisp, Scheme)
    • Procedural: (Python, Java)
    • Low-Level: (C, Assembly)

Examples:

  • LLM's (Large Language Models):GPT-4, Claude-3, Google Gemini
  • High-Level Languages:Python, Java, Cobol, Javascript
  • Assembly Languages:x86, ARM
  • Machine Language:binary
  • Hardware: No programming this is the core hardware that does the work
