Do you which is the worlds most widely used Operating System(OS),If your answer is Microsoft Windows you are wrong OK…Guess again Is it Linux/UNIX?.Sorry this time too neither of them is not also is the answer to the question.Me too think that Windows was the most widely used OS.But OS has a really wide definition it not only operates computers but also embedded system applications too
The most popular OS is ITRON, a Japanese real-time kernel for small-scale embedded systems. ITRON runs on mobile phones, digital cameras, CD players and countless other electronic devices.
ITRON emerged as an ambitious Japanese initiative known as The Real-time Operating system Nucleus (TRON). Launched in 1984, TRON was designed to replace disparate computer systems with a unified, open architecture for a “total computer environment.”
