Abstract
At some point in time, an application will eventually be replaced by a competitor. UNIX ruled the operating system market for several decades. In the early 90's, Novell and Microsoft introduced their respective operating systems and these moves eventually eroded the stranglehold UNIX once had on the market. Microsoft would emerge as a dominate player while Novell and UNIX lost market share. After several years of a largely underground movement, Linux is now poised to wrestle control of the operating system market from Microsoft. For the past three years, shipments of Linux have been growing at a phenomenal rate. According to the Aberdeen group, "Linux shipments, measured by licenses are growing more than 25% per year". Aberdeen.com (2004). This growth is faster than any other operating system. For the purpose of this paper, I intend to discuss the merits of adopting a Linux/UNIX operating system for a work site.
Cost of Linux/UNIX
The total cost of acquisition for software, hardware and additional equipment to support Linux is a very small when you look at the total cost of ownership. A three month study performed IDC found that the "TCO of Linux versus Unix, released today by analyst IDC, reveals a 45 to 80 per cent lower amount for Linux on Intel against Unix on Risc." IDC.com(2004).
The UNIX platform is can be more expensive, the scalability and performance that UNIX brings to the table makes ideal for mission critical applications. Additionally, UNIX based systems are typically hardware redundant and this alone skews the numbers when attempting to perform a cost comparison. Although it is difficult to get an apples to apples comparison of the total cost of ownership between Windows, Linux and UNIX, an overrid...

...stems would be quick and relatively inexpensive. As a preventive measure, the Linux kernel as does UNIX supports multiple processors; downtime could be significantly reduced if these systems were clustered. Core applications that perform critical tasks (i.e. payroll, scheduling) should remain (if not already) on a UNIX platform. Prior to migration of any system, there are three guidelines I would observer. First, I would recommend finding a project that fit the task at hand. If the technician performing the Linux migration has limited experience, targeting web servers for migration would be a good start. If there is a opportunity to migrate a platform to Linux or Unix due to an older version of the OS,
Finally, it is extremely important to make certain that the applications that run on these systems have a port to the version of Linux or UNIX that is being installed.
I was very interested in computers and technology as a child, both playing games and building fake parts for them. Still in elementary school, I was fascinated by these computing machines, spending hours on end working with DOS to satisfy my curiosity. Around my middle school years, Windows became graphical, and I found interest in even more computer games with even greater experiences and capabilities. Windows was the dominant operating system at the time, but I was soon to find there was a whole different world out there of operating systems. While out on vacation in Washington, DC, my Dad and I were able to meet with the local Tech Fanatics group, HackDC. It was here where I discovered Linux. Linux, an alternative to Windows, immediately grabbed my attention when I saw it in use. It appeared to me as something that only the extreme computer users even heard of. Upon my return home,
The purpose of this document is to compare and contrast three different Linux vendors in regards to their specific server and workstation OS products they offer in the workplace. In addition, I will discuss the price for each vendor, specifications, performance, and reliability. The three vendors I would like to discuss are Arch Linux, Red Hat Enterprise, and Ubuntu. Linux is an operating system that has several distros to choose from. Linux allows the user more control of the system and greater flexibility. As an open operating system, Linux is developed collaboratively, meaning no one company is solely responsible for its development or ongoing support. Companies participating in the Linux economy share research and development costs with

Linux is a popular and widely used operating system and provides several options for use within business organizations as both a server and a workstation platform. Due to the open-source nature of the operating system there are various organizations who make available a server and a workstation platform along with their own customizations as part of a specific distribution.

...ctioned, communicated, and performed their daily activities. In doing this however, they must stay on top of other competitors by creating new innovative ways to attract the consumers. Some had a long history while others had a short one. Some were provided great feature while others didn’t do so well in this area. One thing is for certain, each operating system provided a use for many consumers that helped not only in the personal lives of many but also within the business world. As we see the history shows that once upon a time what began as a way to for businesses to operate has now turned into a way that people communicate. Technology continues to grow and advance and with that waiting to see what the future holds is a mystery but I’m certain that it will be world of amazement especially seeing where operating systems have come from to where they are currently.
The reason for this rapid adoption is Linux’s unique ability to provide powerful functionality, security, compatibility, customization at a more cost-effective price than proprietary vendors. In its inception, there were many perceived concerns to utilizing Linux in a corporate infrastructure.
To build a good and stable network is extremely difficult. It takes a team of very knowledgeable engineers to put together a system that will provide the best service and will forfill the need for the companies users and clients. There are many issues that have to be resolved and many choices have to be made. The toughest choices IT managers have to make, are what will be the best server platform for their environment. Many questions must be answered. Which server software offers complete functionality, with easy installation and management? Which one provides the highest value for the cost? What kind of support and performance can be expected from this system? And most important of all is what is more secure? In this paper, Microsoft Windows NT Server is compared to UNIX, in the large commercial environment. The main focus of the comparison is on the areas of, reliability, compatibility, administration performance and security.
Any program is only as good as it is useful- Linus Torvalds. According to Merriam-Webster dictionary an operating system is the main program in a computer that controls the way the computer works and makes it possible for other programs to function. Linus Torvalds in 1991 arranged the UNIX operating system to be used in the stead of ms-dos; Windows 95 was ran on top ms-dos. Windows and Linux are different operating systems built off different systems of code making security, stability, usability, and the communities comparatively different.
Q:18Compare UNIX, Linux and windows in form of table, the table should contain five differences.
Unlike Windows, Linux is a capable of runnig on large variety of computer systems.One of them is Intel Based PCs.Most of the home users prefer Intel Based PCs.So they can run Linux on their computers(Windows can only run on Intel Based PCs).Digital Alpha systems are used by the huge companies.Linux has the capability of running on the Digital Alpha systems so it can reach the advanced users.Other computer system is Macintosh Power PC that is used by graphical designers,press companies and advertising companies, can be run with Linux. The others are Sun Sparc&Sun Ultra, Amiga, 3Com Palm Pilot which are rarely used. This capability of Linux provides a large user number and user kind that makes Linux more popular.(www.linux.org)
I have decided not to discuss cost because it goes without saying: Linux wins the price to performance ratio. What is more important to discuss is the initial hardware and software fees, and maintenance and reliability which often go hand in hand. According to Sunworld, the estimated minimal required hardware costs that would go with a Linux machine is $200. In an NT machine, the minimal hardware cost rose up to $1300. This is because NT requires at least a 486 Pentium with 16MB of RAM. Linux can run fine on a 386 computer with only 8MB of RAM.
An operating system accomplishes the following tasks: interaction between computer and user, providing an environment of which programs operate, and manages files. Yet, each operating system does it its own way. Hence, it is advantageous to know the pros and cons of each operating system before a decision is made. Any kind of operating system can be utilized in most environments; it's just a matter of difficulty supporting it regarding maintenance, compatibility problems and other concerns. For example, the Mac OS X would be perfect for the graphic design department, but would not work out well in the engineering department, which is better suited for Windows or Linux.
When it comes to what makes a modern operating system ideal there are a variety of key elements. The security should be a very important part given the consistent threat of data breachers and brute force attacks. Customizability is also a valuable asset as computer users have different needs, so it needs to be considered. Furthermore an ideal operating system also is free as in freedom so users and developers can improve the code. Ultimately the security, customizability and the overall free nature of Linux make it an ideal operating system. However to fully understand why Linux is an ideal operating system analysis of its strengths are needed.
An Operating system is system software that controls the system’s hardware that interacts with users and the application software. As we all may know, Windows Microsoft has always been a commercial high-level sale in the retail industry and an in domain operating system used today. But there are more operating systems than just Windows Microsoft than the general population may assume. Linux is another well-known operating systems, which is free and open-source software. Linux is also used in companies we would have never thought of like Google, NASA, USPS, Amazon and many more companies. Linux and Microsoft operating systems have been in competition to see which one is the best operating system in the market. There are so many resemblances
