ChromeOS
Objective:
*To compare the pros and cons of
diffrent OS
*To understand their purposes
*To give a final Verdict

4. Understanding what an OS is ?
An operating system (OS), in its most general sense, is software that
allows a user to run other applications on a computing device. While it
is possible for a software application to interface directly with
hardware, the vast majority of applications are written for an OS,
which allows them to take advantage of common libraries and not
worry about specific hardware details.

Mac OS
It is a powerful OS designed by Apple.
At macOS's core is a POSIX compliant
operating system built on top of the XNU
kernel, with standard Unix facilities
available from the command line
interface. Apple has released this family
of software as a free and open source
operating system named Darwin. On top
of Darwin, Apple layered a number of
components, including the Aqua
interface and the Finder, to complete the
GUI-based operating system which is
macOS.

Microsoft Windows
Windows OS, computer operating
system (OS) developed by Microsoft
Corporation to run personal
computers (PCs). Featuring the first
graphical user interface (GUI) for
IBM-compatible PCs, the Windows
OS soon dominated the PC market.
Approximately 90 percent of PCs run
some version of Windows.

12. The first version of Windows, released in 1985, was simply a GUI offered as an extension of
Microsoft’s existing disk operating system, or MS-DOS. Based in part on licensed concepts
that Apple Inc. had used for its Macintosh System Software, Windows for the first time
allowed DOS users to visually navigate a virtual desktop, opening graphical “windows”
displaying the contents of electronic folders and files with the click of a mouse button,
rather than typing commands and directory paths at a text prompt.

13. Advantages Of
Microsoft Windows
1)It has a large User base
2)It has much more
variety
3)Supports a large variety
of Software and games
4)It has a great visual
user interface

6)Hardware choices
available

14. Disadvantages of
Microsoft
1.High resource requirements
2.Closed Source
3.Poor security
4.Virus susceptibility
5.Outrageous license agreements
6.Poor technical support
7.Poor stability
