Windows It is a software operating system and graphical user interface that was developed by Microsoft. Following its introduction in 1985, it became immensely popular among the personal computer users. Its development had begun on two parallel routes. The development on one route was intended for personal use while the other was for professional use. The versions aimed at personal use featured greater multimedia support and lacked networking capabilities. The professional versions of Windows offered greater networking and security features but lacked multimedia support. Windows 7 was a huge success, and the relatively recent Windows 8 is also popular

Mac OS Also known as Mac, Macintosh refers to a brand name that covers a series of personal computers developed by Apple Inc. Apple produces Mac hardware and has its own operating system that comes packaged with all the Macs. The Mac Operating System can be divided into two families of operating systems. One is the 'Classic' Mac OS, which was shipped with Macs until the creation of Mac OS 9. The second family is Mac OS X, which derives its features from Mac OS 9. The operating system that is currently in use is known as Mac OS X, successor of Mac OS, which is a line of graphical user interface-based operating systems.
