Passage A Personal computer software is based on specific operating systems and machines.The famous PC operating systems are DOS,Windows,OS/2,Unix,Linux,Mac OS. DOS (Disk Operating System)was the most popular operating system for IBM and IBM-compatible 16 bit personal computers.DOS is no longer widely used because it has a number of limitations. Microsoft built Windows as an extension of the widely installed DOS operating system. Windows provides not only a graphical user interface(GUI),but also memory management and multitasking capabilities. Unix is an interactive,multi-user,multitasking operating system that is highly supportive of communications and networking.At present,Unix is primarily used for workstations,minicomputers,and server computers in multi-user environments. Linux is the free Unix.It has all of the features you would expect of a modern,fully fledged Unix:true multitasking,virtual memory,shared libraries,demand loading,shared, proper memory management and TCP/IP networking. Mac OS (Machintosh Operating System)supports multitasking and networking and has a highly praised graphical user interface.Multimedia capabilities of this operating system allow Macintosh users to integrate video clip,stereo sound,and animated sequences with conventional text and graphics software. 1483H .
