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.
Tell whether the following statements are true(T) or false(F) according to the passage A.（根据上文的内容判断下列句子的正误）
