What Is The Most Popular OS in the World?
Roland Piquepaille writes "If your answer is Windows, you're plain wrong. It's ITRON, a Japanese real-time OS kernel that can be customized for any small-scale embedded systems. According to LinuxInsider.com, it is used by more than 3 billion microprocessors found in mobile phones, digital cameras, CD players and many other electronic devices including even satellites. The article looks at the competition in this market, notably RTLinux, the real-time version of Linux, and T-Linux, an environment for running middleware. This last effort could lead to the eTRON chip, an encryption device that offers secure data transfer across wireless networks and the Internet. One thing is sure for this market: the future is definitively open-source. This overview contains more details and external references."
