3. operating system
An operating system (OS) is system software that manages computer hardware and
software resources and provides common services for computer programs
Examples
• Some examples include versions of Microsoft Windows (likeMicrosoft Windows
(like Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP),
Apple's macOS (formerly OS X) Chrome OS, and flavors of the open source
operating system Linux
4. • WINDOWS
The history of Microsoft began on April 4, 1975,
when it was founded byBill Gates and Paul
Allen in Albuquerque.
Microsoft Windows is a series
of software operating systems and graphical user
interfaces produced by Microsoft.
Microsoft first introduced an operating
environment named Windows in November 20,
1985 as an add-on to MS-DOS as windows 1.0

10. Software
There thousands of programs available for Linux, and many are available as easy-
to-install software packages all for free. Also, many Windows programs can be run
on Linux using compatibility layers such as WINE. Linux supports a wider array of
free software than Windows.
Windows commands the highest number of desktop users, and therefore the
largest selection of commercial software. It also has the largest selection of video
games by a wide margin.
11. Software Cost
Many of the available software programs, utilities, and games available on Linux
are free and open source. Even complex applications such as GIMP, Open Office,
and Star Office are available for free.
Although there are many free Windows programs, utilities, and games, the
majority of the programs are commercial
12. Security
Linux is a highly secure operating system. Although attack vectors are still
discovered, its source code is open and available for any user to review, which
makes it easier to identify and repair vulnerabilities.
Microsoft has made great security improvements over the years. But as the
operating system with the largest user base, especially among novice computer
users, it is the primary target for malicious coders. As a result, of all major
operating systems, Microsoft Windows is the most likely to be the victim of viruses
and malware.
13. Hardware
Fifteen years ago, Linux struggled to support new hardware. Manufacturers often
considered Linux support a secondary concern (if they considered supporting it at
all). Furthermore, device drivers for Linux were created only by enthusiasts who
devoted their own time and resources to making Linux compatible with new
hardware. Since then, the Linux user base has grown exponentially.
Windows has a massive user base, so it would be madness for a consumer
hardware manufacturer not to support Windows. As a Windows user, you can rest
assured that your operating system is compatible with any hardware you might
buy.
14. Support
There is a massive amount of online support available for Linux.
Microsoft Windows offers integrated and online help systems, and
there are thousands of informative books about Windows available
for every skill level.
