Programming languages can be categorized into different main groups, each with its unique features and applications. Understanding these categories is essential to comprehend the evolution of programming languages and appreciate their impact on the technological world. Below, the key categories are explained:
Machine code consists of sequences of zeros and ones directly understood by a computer processor. It represents the most fundamental form of programming and is specific to a particular hardware architecture. An example of machine code might look like this: 10110000 01100001.
Assembly languages are successors to machine code and provide a more human-readable form of programming. These languages translate symbolic instructions into the corresponding machine language. An example of assembly code could look like this:
High-level programming languages, such as C, Java, and Python, are designed to reduce the complexity of programming. They use readable syntax and provide abstraction from the underlying hardware. Here's an example of a simple program in C:
Fourth-generation languages are specialized languages designed for specific tasks, like SQL for databases and MATLAB for scientific calculations. They enable users to accomplish complex operations with minimal code. An example SQL query might look like this:
Object-oriented languages, such as C++ and Java, organize data into objects containing both data and associated functions. This approach promotes reusability and modularity in the code. Here's an example of a class in Java:
main categories represent the evolution of programming languages, each with its advantages and applications. In the following sections, we will explore some of the most influential programming languages within these categories and discuss their contributions to the world of computer science.
Name of the Programming Language: Fortran (FORmula TRANslation).
Developer(s): IBM (designed by John Backus)
Name of the Programming Language: COBOL (COmmon Business-Oriented Language).
Developer(s): COBOL standardization was led by a committee of technicians from various companies and
government entities. Grace Hopper played a significant role in COBOL's development.
Programming Language Name: BASIC (Beginner's All-purpose Symbolic Instruction Code).
Developers: John G. Kemeny and Thomas E. Kurtz developed the original BASIC language at Dartmouth College in
1964.
Programming Language Name: C.
Developers: C was developed by Dennis Ritchie at Bell Labs in the early 1970s. It was based on the B language
developed by Ken Thompson.
Programming Language Name: Pascal.
Developer(s): Pascal was designed by Professor Niklaus Wirth in 1968 and named after the French
mathematician and philosopher Blaise Pascal.
Programming Language Name: C++.
Developer(s): C++ was developed by Bjarne Stroustrup at Bell Labs in Murray Hill, New Jersey during the early
1980s.
Programming Language Name: Prel.
Developer(s): Larry wall
Programming Language Name: Python.
Developer(s): Python was created by Guido van Rossum. The development of Python started in the late 1980s, and
the first official Python release, Python 0.9.0, came out in February 1991.
Programming Language Name: Ruby.
Developer(s): Ruby was created by Yukihiro Matsumoto, often simply known as Matz, in the mid-1990s in Japan.
Programming Language Name: PHP (Hypertext Preprocessor).
Developer(s): PHP was created by Rasmus Lerdorf in 1994. Over the years, it has been further developed and
maintained by a large and active community of developers.
Programming Language Name: Java.
Developer(s): Java was developed by James Gosling and his team at Sun Microsystems (which was later acquired
by Oracle Corporation) in the mid-1990s.
Programming Language Name: JavaScript.
Developer(s): JavaScript was developed by Brendan Eich while he was working at Netscape Communications
Corporation. The language was first introduced in 1995 as part of Netscape Navigator web browser.
Programming Language Name: Ruby (Rails is a web application framework written in Ruby).
Developer(s): Rails, also known as Ruby on Rails, was extracted by David Heinemeier Hansson from his work on
the project management tool Basecamp at 37signals (now Basecamp). The framework was first released as
open-source in July 2004.
