Are Palm OS Windows CE and Linux real-time operating systems?

Answer 1

Palm OS is generally not considered a real-time operating system. True real-time operating systems are multi-tasking; the "real-time" refers to the ability to effectively manage resources to achieve a result in as little time as possible. Palm OS is single-tasking, so the speed at which it performs is mostly bottlenecked by the individual application running.

Windows CE is a real-time operating system; most uses of it are in multi-tasking devices.

Linux is not necessarily a real-time operating system, but can be configured that way, depending on the scheduler selected.
