Study Notes

Types of Programming Languages

  • Low-level programming languages provide little or no abstraction from a computer's microprocessor.
  • High-level programming languages are more abstract, easier to use, and more portable across platforms.

First Generation of Programming Language (1GL)

  • Machine language is a set of instructions and data that a computer's central processing unit can execute directly.
  • Machine language statements are written in binary code, and each statement corresponds to one machine action.

Second Generation of Programming Language (2GL)

  • Assembly language is the human-readable notation for machine language used to control specific computer operations.
  • Assembly language programmers write instructions using symbolic instruction codes that are meaningful abbreviations or mnemonics.
  • An assembler is a program that translates assembly language into machine language.

Third Generation of Programming Language (3GL)

  • Third generation programming languages, or procedural languages, use a series of English-like words to write instructions.
  • High-level programming languages make complex programming simpler and easier to read, write, and maintain.
  • Examples of third generation programming languages include PASCAL, FORTRAN, BASIC, COBOL, C, and C++.
  • Programs written in a high-level programming language must be translated into machine language by a compiler or interpreter.

Fourth Generation of Programming Language (4GL)

  • The fourth generation programming language, or non-procedural language, enables users to access data in a database.
  • A very high-level programming language is often referred to as goal-oriented programming language because it is usually limited to a very specific application.
  • Examples of fourth generation programming languages include MSQL, NOMAD, and FOCUS.

Fifth Generation of Programming Language (5GL)

  • The fifth generation programming language, or visual programming language, is also known as natural language.
  • Fifth generation programming provides a visual or graphical interface called a visual programming environment for creating source codes.
  • Fifth generation programming allows people to interact with computers without needing any specialized knowledge.
  • Python is a well-known fifth-generation language.
