Different Types of Operating System
Operating system (commonly abbreviated to OS, O/S or kernel) is an interface between hardware and
software in a computer system. The OS is responsible for the management and coordination of
activities and the sharing of the limited resources of the computer. The operating system acts as a host
for applications that are run on the machine. As a host, main purposes of an operating system are to
handle the details of the operation of the hardware.

MICROSOFT WINDOWS
Microsoft Windows is a family of proprietary operating systems that originated as an add-on to the
older MS-DOS operating system for the IBM PC. Modern versions are based on the newer Windows
NT kernel that was originally intended for OS/2. Windows runs on x86, x86-64 and Itanium
processors. Earlier versions also ran on the DEC Alpha, MIPS, Fairchild (later Intergraph) Clipper
and PowerPC architectures (some work was done to port it to the SPARC architecture).
As of June 2008, Microsoft Windows holds a large amount of the worldwide desktop market share.
Windows is also used on servers, supporting applications such as web servers and database servers. In
recent years, Microsoft has spent significant marketing and research & development money to
demonstrate that Windows is capable of running any enterprise application, which has resulted in
consistent price/performance records (see the TPC) and significant acceptance in the enterprise
market.
The most widely used version of the Microsoft Windows family is Windows XP, released on October
25, 2001. In November 2006, after more than five years of development work, Microsoft released
Windows Vista, a major new operating system version of Microsoft Windows family which contains
a large number of new features and architectural changes. Chief amongst these are a new user
interface and visual style called Windows Aero, a number of new security features such as User
Account Control, and a few new multimedia applications such as Windows DVD Maker. A server
variant based on the same kernel, Windows Server 2008, was released in early 2008. Windows 7 is
currently under development; Microsoft has stated that it intends to scope its development to a three-
year timeline, placing its release sometime at the end of 2009.
For this project Microsoft Windows XP(professional) have been chosen.

LINUX
Developed by Linus Torvalds and further elaborated by a number of developers throughout the world,
Linux (lee'nuhks/ or /li'nuks/,_not_/li:'nuhks) is a freely available multitasking and multiuser
operating system. From the outset, Linux was placed under General Public License (GPL). The
system can be distributed, used and expanded free of charge. In this way, developers have access toall the source codes, thus being able to integrate new functions easily or to find and eliminate
programming bugs quickly. Thereby drivers for new adapters (SCSI controller, graphics cards, etc.)
can be integrated very rapidly.
UNIX
UNIX, which is not an acronym, was developed by some of the members of the Multics team at the
bell labs starting in the late 1960's by many of the same people who helped create the C programming
language. The UNIX today, however, is not just the work of a couple of programmers. Many other
organizations, institutes and various other individuals contributed significant additions to the system
we now know today.
MS DOS
Short for Microsoft Disk operating system, MS-DOS is a non-graphical command line operating
system created for IBM compatible computers that was first introduced by Microsoft in August 1981
and was last updated in 1994 when MS-DOS 6.22 was released. Although the MS-DOS operating
system is not commonly used today, the command shell used through Microsoft Windows is.
Unlike Microsoft Windows, which most users are familiar with today, MS-DOS requires the user to
type commands instead of using a mouse. The image to the right is an example of what an MS-DOS
window more appropriately referred to as the Windows command line looks like under Microsoft
Windows. [P3]
Customizing operating system
In order to make the system easier to the user it is a good idea to customize the operating system
according to the user task. Few customize options are
Customising Desktop
Some important icon such as My Computer, Recycle Bin, and My Document can be place on desktop
for increasing working speed. Right click from the mouse we get PERSONALIZE option. Select
CHANGE DESKTOP ICON then select required icons.
Microsoft Word
As an organisation there are so many things need to type in every moment. So word icon can be place
on desktop.
Microsoft Excel
Apex is a financial institution, there are accounts need to keep in spreadsheet programs. It is a good
idea to keep spreadsheet icon in desktop.

Microsoft Power Point
Convincing the buyer as well as the supplier it is very necessary to present the companys status so
nicely so other party will have a clear idea about us. so power point could be place on desktop.
Internet Explorer
The most important things for surfing on the net is inter net explorer. So it will be placed on desktop
Date and Time
For remembering the date and time we can place the time and date in task bar.
User Accounts
In order to use the computer more than one employee the operating system can be spitted in many
user accounts. For make a different user account, go to CONTROL PANEL from start menu. Open
the USER ACCOUNT make account as much as need. This account can be protected by password.
Display setting
As it is a office employees have to pass a long time in front of computer. So it is very necessary to
keep the monitor display in good resolution. Display setting can be made from PERSONALIZE then
click display setting.
[P4]
Health & Safety
Health and safety is a very important issue for a computer system. User may be severely affected
because of improper use of computer. Few tips for using pc carefully:
Keyboard
In the time of sitting the computer it is better to place the keyboard by keeping few distances from the
monitor. Always keeping the wrist straight when typing.
Mouse
holding the mouse softly and dont click them. When using mouse keep the wrist straight.
RSI - In order to avoid
Sitting comfortably user can avoid the risk of repetitive stain injury. for these reason chair and the
table should adjust properly.
Eye strain

Continuous looking at the flickering screen seriously affects our eyes. Adjusting the brightness and
contrast option as well as enough lighting in the room can avoid this problem.
In setting time, formatting the text that is large enough to read easily on screen, when sitting in a
normal, comfortable working position. selecting colours that are easy on the eye (avoid red text on a
blue background, or vice-versa). [P10]

User Documentation
In order to familiars the new system with employees, there is a user manual should be
provided. This user documentation will help the employee to run the system frequently.

Security
In order to secure the system the latest version of AVG anti virus installed with our system. Network
licence copy is better to keep all computers secure of this network. Network licence is cheaper rather
then buying anti virus separately. I choose McAfee total protection 2009.Its work

Computer Platform
Anti-virus, anti-spyware, anti-spam, and Site Advisor protect computer from malicious
software.
Firewall blocks outsiders from hacking into PC.
Local backup protects electronic files if they are deleted or lost.
Identity theft protection, anti-phishing, and Site Advisor all help keep your identity safe.
Full backup:
As we know the company hold so many information that deals with lots of other company and their
database. So it is very important to make a strong a data backup for it. Full backup involves taking a
copy of all data, applications and system files by storing it. [P9]
Training
For the new computer system the user need training about the basic of computing. They should know
about the possible faulty reasons for hardware and software. The manual book and few related books
can help them a lot.
Conclusion
The system has been setup successfully. All the pc are working properly. New IT sector will help to
expand the business. Organizations rely on computer and information technology to conduct business
and operate efficiently. Apex will get benefit by adopting new technology because it will increase
their business image.
