4. An Operating System (OS) is an interface
between a computer user and computer hardware. An
operating system is a software which performs all the
basic tasks like file management, memory management,
process management, handling input and output, and
controlling peripheral devices such as disk drives and
printers etc. The two most common Computer Operating
Systems are
⁙Windows
⁙ MacOS

5.  Single & Multi tasking
 Single & Multi Users
 Distributed
 Tempelated
 Real-Time

6.  Linux
 Unix
 MacOS
 Windows
 McIntosh
 Android
 I O S
 MS DOS

7. Linux is a tried-and-true, open-source
operating system released in 1991 for
computers, but its use has expanded to underpin
systems for cars, phones, web servers and, more
recently, networking gear.
Its longevity, maturity and security make it one of
the most trusted OS available today, meaning it
is ideal for commercial network devices as well
as enterprises that want to use it and its
peripherals to customize their own network and
data center infrastructure.

8. 1) Better Security
2) Good Privacy
3) Large Community
Support
4) Free to Use
5) High Performance
6) High Stability
7) Runs Multiple Desktops
8) Proper use of Hard Disk

9. The original Unix operating system was
developed at AT&T's Bell Labs research center
in 1969. The Unix operating systems and Unix-
like variants run on a wide variety of digital
architectures, and are commonly used on web
servers, mainframes, and supercomputers. In
recent years, smartphones, tablets, and
personal computers running versions or
variants of Unix have become increasingly
popular. Unix was developed using a high-level
programming language instead of platform-
specific assembly language.

10. 1) Hierarchical File System
2) UNIX shell
3) Utilities
4) Machine-independence
5) Portability

11. It was announced in November 1983
under the name "Windows" , but the original
Windows 1.0 was released in November 1985
and was Microsoft's first true attempt at a
graphical user interface in 16-bit. It is one of
the most commonly used Graphical User
Interface OS in the World. In this OS some
elements are Open and some are for
Purchase. The Windows OS Dominated the
PC Market very soon.

12. 1) Easy to Use
2) Backwards Compatibility
3) Plug & Play
4) Games
5) Compatibility with MS websites

13. MacOS is a series of proprietary GUI operating
systems developed and marketed by Apple Inc. since
2001. It is the primary operating system for Apple's
Mac computers. Within the market of desktop, laptop
and personal computers, and by web usage, it is the
second most widely used desktop OS, after Microsoft
Windows. MacOS is the direct successor to the
classic Mac OS, the line of Macintosh operating
systems with nine releases from 1984 to 1999.
MacOS adopted the Unix kernel and inherited
technologies developed between 1985 and 1997.

14. 1) Similar GUI for all the products
2) Fewer virus attacks
3) Default apps
4) Performance and long life
5) Good customer support

15. MS-DOS is a text-based operating
system for x86-based Personal Computers,
meaning that a user works with a keyboard to
input data and receives output in plain text.
Later, MS-DOS often had programs using a
mouse and graphics to make work more
simple and quick. MS-DOS was released as
proprietary software, but decades later after
most users had gone to other systems, it was
released as free software.

16. 1) Run on Smaller System
2) Very Lightweight
3) Boot much faster
4) Easy direct eccess to BIOS

17. Android is a mobile operating system based
on a modified version of the Linux kernel and
other open source software, designed
primarily for touchscreen mobile devices such
as smartphones and tablets. Android is
developed by a consortium of developers
known as the Open Handset Alliance and
commercially sponsored by Google. It was
unveiled in November 2007, with the first
commercial Android device launched in
September 2008.

18. 1) Universal Chargers
2) Removable Storage
3) Better Hardware
4) More App Choices
5) More Phone Choices
