C (programming language)

In computing, C is a general-purpose, cross-platform, block structured, procedural, imperative computer programming language developed in 1972 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system.

Although C was designed for implementing system software, it is also widely used for developing application software.

It is widely used on a great many different software platforms and computer architectures, and several popular compilers exist. C has greatly influenced many other popular programming languages, most notably C++, which originally began as an extension to C.

Histroy of Linux

Linux is a multiuser - multitasking operating system. This was developed by Linus Bendedict Torralds a second year computer science student of Helsinki University. This operating system is a colone of unix operating system. This was designed and developed mainly to incorporate all the functionalities of unix for PC users.

The first version of Linux 0.01 was released in mid September 1991 over the internet. Linus holds the copy right, but allowed other users to use the software freely. The users can modify and resell the modified versions. Many interested programmers added many applications and features such as windows manager, networking tools, program development utilities such as C, C++ compilers and debuggers.

Although Linux is free and open environment in the internet, it follows the official standard of unix called POSIX (Portable Operating System Interface for Computer Environments) given by IEEE.
