Study Notes

Computer Architecture

  • Computers utilize a fundamental architecture comprising both hardware and software components.
  • Hardware encompasses physical devices like the central processing unit (CPU), memory (RAM), storage devices (hard drives, SSDs), input/output devices (keyboard, mouse, monitor), and network interfaces.
  • Software consists of programs, instructions, and data that tell the hardware what to do.
  • CPUs perform arithmetic and logic operations, controlled by instructions encoded as machine code.
  • Memory stores data and instructions that the CPU needs to execute programs.
  • Storage devices retain data even when the computer is turned off.
  • Input/output devices allow users to interact with the computer and the external world.
  • Network interfaces enable communication between computers.

Programming Languages

  • Programming languages are formal languages used to instruct computers to perform specific tasks.
  • They translate human-readable code into machine code understood by the computer's CPU.
  • Different programming languages have distinct syntax, semantics, and features.
  • Common programming paradigms include procedural, object-oriented, functional, and logic programming.
  • Procedural languages (e.g., C, Pascal) structure programs as a sequence of procedures or functions.
  • Object-oriented languages (e.g., Java, C++) organize programs around objects that contain data and methods.
  • Functional languages (e.g., Haskell, Lisp) emphasize functions as the primary means of computation.
  • Logic programming languages (e.g., Prolog) use logical statements to describe problems and solutions.
  • Programming languages often involve different levels of abstraction, ranging from low-level languages like assembly language to high-level languages like Python or JavaScript.
  • Low-level languages are closer to machine code, offering fine-grained control over hardware but requiring more complex code.
  • High-level languages provide higher abstraction and ease of use, but they require translation steps to machine code.
  • Popular high-level programming languages are used for diverse purposes: web development (JavaScript, Python), mobile app development (Swift, Kotlin), data science (Python), game development (C++, C#), and system programming (C).
  • Programming languages usually have compilers, or interpreters to translate code into machine-executable instructions.
  • Compilers translate the entire program into machine code before execution.
  • Interpreters translate and execute code line by line.
  • Programming environments provide tools for writing, testing, and debugging programs (integrated development environments, or IDEs).
  • Programming involves logical problem-solving, algorithmic design, and code implementation.
  • Code needs to be correctly structured and semantically valid.
