They are typically manufactured by large companies for large-scale computing purposes

Embedded Systems Embedded systems are special-purpose

systems in which the computer is completely encapsulated by the device it controls.

Embedded systems perform pre-defined tasks that have very specific requirements.

Real-time operating systems are embedded systems with certain time requirements

Unix-like OS

The operating system Unix was developed in 1960 by a group of AT&T employees.

Free Unix-like operating systems can be used, studied, modified and redistributed by anyone with no restrictions.

Unix-like OS

It's a diverse group of operating systems with several major sub-categories including BSD, and Linux.

Unix like operating systems run on a variety of computers but more frequently on server systems and in academic and engineering environments due to high stability for any kind of processing

Mac OS Apple's Macintosh OS is an operating

system with a very innovative and unique design.

The history of the company behind it, Apple, that's been around since 1976 is fascinating and so is its cool operating system Mac OS.

WebOS The WebOS (Web Operating System) represent

a new form of virtual operating system that runs directly in your browser.

The main advantages of a web operating system is that you can access it from anywhere but it's very arguable if it's really an operating system or not because it runs over a browser window and have no relation whatsoever with the hardware and its drivers.

You will still need an operating system to run a WebOS.
