Final answer:
VxWorks is based on the Wind microkernel and is distinct from the Linux and UNIX kernels. It is renowned for its use in embedded systems, while Linux is also extensively used in various applications but is based on open-source principles.
Step-by-step explanation:
VxWorks is centered around the Wind microkernel. It is a real-time operating system (RTOS) developed by Wind River Systems, which is distinct from the Linux kernel developed by Linus Torvalds or the UNIX kernel. While VxWorks is used for embedded systems, it is worth noting that Linux has also been widely adopted for various applications including embedded systems, file servers, and internet routers since its creation. However, despite Linus Torvalds's contribution to the open-source ecosystem through the development of Linux, VxWorks remains built on its proprietary microkernel architecture.
