Types of Programming Languages:

  1. Low-Level Languages:
    • Machine Language: Directly executed by the computer’s CPU; written in binary (0s and 1s).
    • Assembly Language: Uses symbolic representations of machine instructions, requiring an assembler to convert to machine code.
  2. High-Level Languages:
    • Easier for humans to read and write; translated to machine code by compilers or interpreters.
    • Examples: Python, Java, C++, JavaScript, Ruby.
  3. Scripting Languages:
    • Designed for automating tasks within other software.
    • Examples: Python, JavaScript, Perl.
  4. Markup and Query Languages:
    • Focused on structuring and managing data rather than performing computations.
    • Examples: HTML, XML, SQL.
  5. Domain-Specific Languages (DSLs):
    • Tailored for specific applications or domains.
    • Examples: MATLAB (for mathematical computations), R (for data analysis).
  6. Object-Oriented Languages:
    • Focus on objects (data structures containing data and methods).
    • Examples: Java, C++, Python.
  7. Functional Languages:
    • Emphasize mathematical functions and immutability.
    • Examples: Haskell, Scala.
