C programming

In computing, C  is a general-purpose programming language initially developed by Dennis Ritchie between 1969 and 1973 at AT&T Bell Labs.Like most imperative languages in the ALGOL tradition, C has facilities for structured programming and allows lexical variable scope and recursion, while a static type system prevents many unintended operations. Its design provides constructs that map efficiently to typical machine instructions, and therefore it has found lasting use in applications that had formerly been coded in assembly language, most notably system software like the Unix computer operating system.

about Linux

Linux is a Unix-like computer operating system assembled under the model of free and open source software development and distribution.It is programmed in various (notably C and assembly languages).It’s OS kernel was first released on 5-Oct-1991,by Linus Torvalds. Tux is a penguin character(above shown) and the official mascot of the Linux kernel.

about

Python is a high-level, structured, open-source programming language that can be used for a wide variety of programming tasks. Python was created by Guido Van Rossum in the early 1990s, its following has grown steadily and interest is increased markedly in the last few years or so. It is named after Monty Python’s Flying Circus comedy program.

Raspberry Pi

Raspberry Pi is a credit-card-sized single board computer.It is a low-cost ($25-$35)  Linux system which was developed by Raspberry Pi Foundation with the primary goal of teaching computer programming to children.The device is expected to have many other applications both in the developed and the developing world.This is the one of the most advanced developments of embedded systems.
