HIGH-LEVEL LANGUAGE
A high-level language lets programmers

write machine-independent programs
using English-like commands, making it Fortran, developed in 1957, was the first high-level
easier to read and write than low-level language specifically designed for scientific and
languages. It is used to create software for mathematical computations.
different computers and devices.

Third Generation Language

Third Generation languages use English-like commands, are easier to read and write and are
machine-independent with a compiler or interpreter. Examples include C, C++ and Java.

Fourth Generation Language

Fourth Generation languages focus on what to do, not how to do it. They are faster, easier and
closer to human language. Examples include SQL, MATLAB and R.

Fifth Generation Language

Fifth Generation languages use visual tools and logic-based programming. They aim to build
systems that solve problems using Artificial Intelligence. Examples include Prolog, LISP, etc.

LANGUAGE TRANSLATOR

A language translator converts high-level code into machine language so the computer can run
it. The main types are Assembler, Compiler and Interpreter.

ASSEMBLER
An assembler translates assembly language into machine code (0s and 1s) that the computer
can understand and process.

COMPILER

A compiler translates the entire source code into machine language at once and shows all errors
after compilation.

INTERPRETER

An interpreter translates and runs code line by line, showing errors one at a time, unlike a compiler.

PYTHON

Python is a simple, readable high-level language used in web development, data analysis, AI
and scientific computing. Created by Guido van Rossum in the late 1980s, it was named after the
comedy show Monty Python’s Flying Circus.
