The Right OS for Your Job

1. The Right OS for Your Job Major: Computer Science Instructor: Dr Anvari Presenter: Ke Huang Student ID: 105450

2. Selecting The OS to Meet Your Needs • Determining your Needs • Identifying solutions • Determining the best solution

3. Definition of Operating System • An operating system is a collection of programs that manage the resources of the system, and provides a interface between the user, the hardware, and the applications.

4. Determining Your Needs • Where is start point? • Understanding the day to day operation of selling and buying produces and services • Security become very important when opening an environment to external access.

5. Determining Your Needs • Management requirements • Individual political agendas • Culture of the organization • Quality of recent revenue • Culture • What is culture of a company. • Company’s culture can directly affect the type of network infrastructure and operating system that your organization deploys.

6. Determining Your Needs • Political Issues • Leaning who these senior managers are and working to satisfy their individual requirements is important to growing a systems department. • Business Trends • Your need to measure the profitability of your organization by using the tools provided by corporate accounting. • IS Personnel • There is a wealth of education and skill-enhancing information available.

7. Identifying Solutions • UNIX – Linux • Customized versions of UNIX that work in conjunction with hardware workstations developed by Digital Equipment Corporation, Hewlett-Packard, and Sun Microsystems. • UNIX operation system were originally conceived and built to be robust and support net-worked equipment. • Unix operating system support variety of network hardware and network protocol. • Linux is the version of UNIX that has been adapted to run on the Intel processor.

8. Identifying Solutions • Windows NT4 • Depending on your point of view, Windows NT4 may be the end of UNIX . • This is network operating system that provides most of same functionality as found in UNIX operating systems. Because it is not based on any underlying operating system and is in fact a multitasking environment.

9. Identifying Solutions • Windows 2000 • New major upgrade from Microsoft • The underlying Executive and microkernel architecture is fundamentally the same as in NT4.0.but new features have been added. • The emphasis in W2K is the addition of services and functions to support distributed processing.The central element of W2K ‘s new features is Active Directory, which is a distributed directory service able to map names of arbitrary objects to any kind of information about those objects.

10. Identifying Solutions • Netware • This is market-leading network. Netware has been designed as network operating system. And specifically, as a file, print, and application serve operating system developed by Novell. • Netware still requires an underlying operating system.

11. Identifying Solutions • Financial Responsibility • The simplest method of determining return on investment (ROI) is to use the “payback method” totaling all the relevant costs to implement new technology and comparing that figure to the recurring savings. • Existing Infrastructure • What kind of infrastructure already exists? There might be Ethernet, Token Ring, or FDDI technologies. • What do the switched technology expect to be able to do with existing equipmen • .

12. Determining the Best Solution • Switch Technology: • In today’s high-performance networking environment, switching technology is the preferred method of transporting. • This technology creates direct connections. • Another excellent feature is switching’s ease of use.

13. Determining the Best Solution • Small Environments-Fewer Than 100 Users • On the desktop side: • Windows environments for desktop. • On the serve side: • Novell does a very good job of supporting file and print services, These are the primary requirements for the majority of small network users. • Microsoft NT has its advantages in an environments that load and runs application from central server. • UNIX does a fine job of both print and file support, as well as application sharing. But this robust, IP-based operating system and is quite difficult to master. • The cost for licensing and supporting, and analyzing the type of network usage is important also.

14. Determining the Best Solution • Medium Environments ( From 100 to 1000 ) • On desktop side: • Windows 98 make sense as the desktop OS. • On the server side: • Novell still have the largest segment of the server market, support for Novel–based system is everywhere and usually good skill can be acquired for a reasonable cost. • Microsoft’s premier network OS, NT4, is being linked more closely to many mission-critical application being rolled out in leading organizations. By providing integrated support for Novel and other internetworking protocols, this networking OS’s graphically based ease of use is winning over customers. • UNIX still requires highly paid support personnel and is tied to the internet and scientific community.

15. Determining the Best Solution • Large Environments ( More than 1000 ) • The combination of existing networks, typically Novell, as well as new applications, typically Microsoft-based, have caused a mixture of platform for the network group to support. • As new powerful application are coming out, you will see a lot of platform dependent on Microsoft NT. • Microsoft’s favor is the integrated support for network protocols. Interface has been developed that work with Novell and TCP/IP. • Choose the network OS that has the features that are necessary for you to do business. Hire staff trained in multiple categories. Find the products that fit your environment the tightest and effectively provide the kind of support necessary to do business.
