Linux status as the most
prominent free software and
Open Source Operation
System on the last 10 years
Was developed by Linus
Torvalds at the University
of Helsinki in 1991
Root in Linux
In Linux, the administrator is
called “root”, and you should use
root access only when you
absolutely need it
such as when you try to
install programs or
modify system settings.
Help is available
One of the best parts
about switching to
Linux is that there are
plenty of people who
have done it before
Command-line interface
The command line can be
used to recover the system if
the graphics subsystem fails
Partitioning
All Linux distributions
have bundled partitioning
software such as fdisk or
gparted
File Systems
Linux, Supported: ext2, ext3, ext4,
ReiserFS, FAT, ISO 9660, UDF, NFS,
NTFS, JFS, XFS, Minux and
GmailFS.
Memory
Management
Disk
This reduces slowdown
due to disk
fragmentation from
general used
Emulation and virtualization
VMware, VirtualBox, Xen, Parallels, Win4Lin. KVM
and QEMU can be used to run other operating
systems within Linux
Open vs. Closed
Anyone with programming experience is free to
fix bugs and submit them for inclusion in future
releases and updates.
Windows
Windows has retained an
extremely large retail seles
personal desktop computers
Don’t login as Admin
It’s common practice for
Windows users to login as
the system administrator all
the time.
This is one of the major reasons
why Windows computers are so
easily infected with viruses and
malware
Full vs. partial
hardware support
Windows, you know that
most every piece of hardware
will work with the operating
system
Command-line interface
The Command Prompt exists to
provide direct communication
between the user and the
operating system
Partitioning
Windows, expanding NTFS partitions is possible
without problems, and on Vista it is possible to
shrink partitions as well.
File Systems
Windows supported:
NTFS, FAT, ISO 9660,
UDF, and others
Memory
Management
Disk
Windows NT family (including 2000, XP,
Vista, Win7) most commonly employs a
dynamically allocated pagefile for memory
management
Emulation and virtualization
VMware, VirtualBox, Virtual PC, Virtual Server, Hyper-V (only
available on 64-bit versions of Vista SP2, Windows 7, and
Windows Server 2008), Parallels, QEMU can be used to run
other operating systems within Windows.
Open vs. Closed
In Windows, Claims its platform is more secure
because of a comprehensive approach to security
using the Security Development Lifecycle
Linux and Microsoft Windows differ in
philosophy, cost, versatility and stability, with
each seeking to improve in their perceived
weaker areas. Comparisons of the two operating
systems tend to reflect their origins, historic user
bases and distribution models
The essence of this study is to
demonstrate a setof proposed
metrics for quantifying the security
risksinvolved in different operating
systems, andcomparing the risks
between operating systems.
Table1
descriptive statistics

Windows is
dominant in the
server segment
Table 2
presents the changes in the use of
operating systemsand the number of
computers in each segment over time
Table 3
Panel B shows that more firms
switched from Windowsto Linux
than from other operating systems
to Linux
Panel C of Table 3 reports
the fractions of firms that

Panel A which reports that
about 32.3% of firms have
