This document discusses several programming languages including BASIC, C, C++, Java, HTML and their key features. It explains that a programming language is a set of rules that tells a computer what operations to perform and that programs are executed as machine code after being compiled from a high-level to a low-level form. Each language is designed for different purposes such as systems programming, object-oriented programming, or web development.

2.  A programming language is a set
of rules that provides a way of
telling a computer what
operations to perform.

3.  High-level Program
Low-level program
 Executable Machine code

4.  Imperative Programming (C)
 Object-Oriented Programming (C++)
 Logo/Declarative Programming
(Prolog)
 Functional/Applicative
Programming(Lisp)

5.  Beginner’s All-purpose Symbolic
Instruction Code.
 Developed at Dartmouth College in
mid1960s
 Developed as a simple language for
students to write programs with which
they could interact through terminals.

6. C
 Developed by Bell Laboratories in the
early 1970s.
 Often Used For System Programs.
 Unix is Written In C.

7.  It is C Language with additional
features.
 Widely Used For Developing system
and application software.
 Graphical user interfaces can be
developed easily with visual
programming tools.

8.  An object-oriented language
similar to C++ that eliminates lots
of C++’s problematic features.
 Objective of JAVA developers is
that it be machine, platform and
operating system independent.

9. • HTML
 Hyper Text Markup Language.
 Used on the internet and the world wide
web (WWW).
 Web Page developer puts brief cods
called tags in the page to indicate how
the page should be formatted
