Which of the following are commercially claimed RTOS?LinuxWindows CESun SolarisVX Works

To determine which of the following options are commercially claimed RTOS, we need to understand what an RTOS is. RTOS stands for Real-Time Operating System, which is an operating system specifically designed to handle real-time applications. Real-time applications require precise and predictable timing, making an RTOS crucial for their execution.

Now, let's analyze each option:

1. Linux: Linux is not typically considered a real-time operating system. While there are real-time variants of Linux available, such as PREEMPT-RT and Xenomai, the standard Linux kernel is not designed specifically for real-time applications. Therefore, Linux is not a commercially claimed RTOS.

2. Windows CE: Windows CE, also known as Windows Embedded Compact, is an operating system designed for embedded systems. It does support real-time capabilities and is often used in industrial and handheld devices. Therefore, Windows CE can be considered a commercially claimed RTOS.

3. Sun Solaris: Sun Solaris, now known as Oracle Solaris, is a Unix-based operating system. While Solaris does have some real-time features, it is not primarily marketed as an RTOS. Therefore, Sun Solaris is not a commercially claimed RTOS.

4. VX Works: VxWorks is a real-time operating system developed by Wind River Systems. It is widely used in industries such as aerospace, defense, and automotive, where real-time performance is critical. Therefore, VX Works is a commercially claimed RTOS.

In summary, the commercially claimed RTOS among the given options are Windows CE and VX Works.
