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.

Computer Platform

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.

Computer Platform

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

[Type text] Page 11


12/18

Computer Platform

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]

[P7]

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

[Type text] Page 15


16/18

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.
