files. The operating system also lets you run programmes such as the basic word
processor. Lastly, the operating system provides several of its own commands that
help you to use the computer.
DOS is the most commonly used PC operating system. DOS is an abbreviation
for disk operating system. DOS was developed by a company named Microsoft. MS-
DOS is an abbreviation for «Microsoft DOS». When IBM first released the IBM PC
in 1981, IBM licensed DOS from Microsoft for use on the PC and called it PC-DOS.
From the users perspective, PC-DOS and MS-DOS are the same, each providing the
same capabilities and commands,
The version of DOS release in 1981 was 1.0, Over the past decade, DOS has
undergone several changes. Each time the DOS developers release a new version,
they increase the version number.
Windows NT (new technology) is an operating system developed by
Microsoft. NT is an enhanced version of the popular Microsoft Windows 3.0, 3.1
programmes. NT requires a 386 processor or greater and 8 Mb of RAM. For the best
NT performance, you have to use a 486 processor with about 16 Mb or higher. Unlike
the Windows, which runs on top of DOS, Windows NT is an operating system itself.
However, NT is DOS compatible. The advantage of using NT over Windows is that
NT makes better use of the PC's memory management capabilities.
OS/2 is a PC operating system created by IBM. Like NT, OS/2 is DOS
compatible and provides a graphical user interface that lets you run programmes with
a click of a mouse. Also like NT, OS/2 performs best when you are using a powerful
system. Many IBM-based PCs are shipped with OS/2 preinstalled. UNIX is a multi-
user operating system that allows multiple users to access the system. Traditionally,
UNIX was run on a larger mini computers to which users accessed the systems using
terminals and not PC's, UNIX allowed each user to simultaneously run the
programmes they desired. Unlike NT and OS/2, UNIX is not DOS compatible. Most
users would not purchase UNIX for their own use.
Windows 95 & 98, are still the most popular user-oriented operating systems
with a friendly interface and multitasking capabilities. The usage of Windows95 and
its enhanced version Windows 98 is so simple that even little kids learn how to use it
very quickly. Windows 95 and 98 are DOS compatible.
The new series of operating system by Microsoft are Windows Millenium,
Windows 2000 and Windows XP. Each of these new products is addressed to the
both corporate and private clients". New strategy of the Microsoft is aimed at creating
«a one for alb product, which will be useful for both the beginners and advanced
users.
