Some most popular examples of operating system are: Unix Operating System. It originally began as a one man project led by Ken Thompson of Bell Labs, and has since grown to become the most widely used operating system.• In the time since UNIX was first developed, it has gone through many different generations and even mutations. Sockets – A Unix socket (or Inter-process communication socket) is a special file which allows for advanced inter-process communication. Linux is neither pure SYSV or pure BSD. Any unauthorised copying or mirroring is prohibited. UNIX has a simple user interface called the shell that It is the responsibility of the kernel to make sure all the system and user tasks are performed correctly. Portable – Portability means softwares can works on different types of hardwares in same way.Linux kernel and application programs supports their installation on any kind of hardware platform.
