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.
The philosophy of freedom is an integral part of the Linux operating system. That must be noted since the belief that Linux should be free as in freedom has been around since its beginnings in 1991(Torvalds & Diamond IX). For better understanding one must pay attention to how the computing community was at the time when Linux was being developed. Unix had been quite popular for many years but following the AT&T split it began to be sold by licensing companies (Negus 10). One issue was that the price for Unix was based off of large mainframes instead of individual personal computers (Negus 11). Linux began with the need for a

One way this can be seen is since there are many distributions that cater specifically to the certain needs of a computer user. For example, TAILS was created solely to stay anonymous online (“Linux” 143). TAILS achieves this by forcing a user’s internet traffic through an anonymity network such as Tor or I2P (“Frequently¬”). Likewise since TAILS is based on Debian it can use all of Debian’s software such as the privacy minded software included with TAILS (“Frequently¬”). Thanks to the mix of security and ease of use (such as from the before mentioned Debian
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,
Yes it indeed bears repeating, “Freedom Is Not Free!” Its acquisition from King George’s England involved struggle, its maintenance throughout the first two and a quarter centuries of our Great Republic required sacrifice and its continuation demands perseverance. Wise people fully realize that struggle, sacrifice and perseverance are the vital characteristics of freedom, democracy and independence. In the late 1930s complaisant European nations were lulled into the jaws of the very dangerous “victim/slave mentality.” Weak democracies tried placating and accommodating the tyrannical proponents of the Communist, Socialist and Fascist ideologies and Europe soon found itself in jeopardy with maniacs like Stalin, Hitler and Mussolini threatening the existence of taken-for-granted freedom and human rights.
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
Do you consider your life full of freedom?Perhaps you overlooked some freedoms and took them for granted. Freedom is defined as having the power or right to speak, think, or act without hindrance or restraint. There are many examples of freedom being demanded. Even America has had its share of wars for freedom from the Revolutionary war to the Civil war. Freedom is never given, but demanded.
When most people think of freedom, they think of being free from a higher power which can be true depending on the scenario. Freedom comes in all shapes and sizes. Freedom is the right to behave a certain way, speak a certain way, or think a certain way, all of which you are free to choose. Freedom has a number of ways that it can be viewed. In some cases,
If we knew how freedom would be used, the case for it would largely disappear. We shall never get the benefits of freedom, never obtain those unforeseeable new developments for which it provides the opportunity, if it is not also granted where the uses made of it by some do not seem desirable. It is therefore no argument against individual freedom that it is frequently abused. Freedom necessarily means that many things will be done which we do not like. Our faith in freedom does not rest on the foreseeable results in particular circumstances but on the belief that it will, on balance, release more forces for the good than for the
The question of becoming free came about and the answer was communism. Karl Marx had the notion that when the monarchy and capitalism were oblivious, then the communist government could take action, and the riches of society would prosper. Contrasting the beliefs that had started becoming prevalent, Marx thought that the economy should have nothing to do with labor, profits, and land tenure. Instead, Marx thought that the foremost point was man and his activities, as declared in the Communist Manifesto. Marx had a resolution to the problems of the working class man; bring the economy to man's direction in order to allow freedom. But, the next issue was, what else is relevant to freedom? Marx talks about this matter in the Communist Manifesto as well. Do the ethics of freedom concern everyone? And how would these ideals be set into today's society?
Freedom remains the sole basis for American society as we know it. Without freedom the great nation of America would have never been founded. To understand the true principles of freedom, one must understand the scope of the word. Philosophical freedom encompasses the ability to make choices without restraints, while political freedom is the state of being free rather than in physical confinement. Despite the importance of these ideas to our founding fathers, freedom has lost much of its importance in modern American society. The failure to stress the importance of freedom has diminished the quality of life for the entire American populous
Windows based computers are more practical for many reasons. Possibly the most prevalent of these being that everybody uses them. When using computers consistency is very important. If everyone is using a certain operating system and software, it is easier to transfer, share, and use the data you create. Windows based systems are the standard in our community, and that is not due to change any time soon.
It all began in 1991, during the time of monumental computing development. DOS had been bought from a Seattle hacker by Bill Gates, for a sum of $50,000 – a small price for an operating system that had managed sneak its way across the globe due to a clever marketing strategy. Apple’s OS and UNIX were both available, though the cost of running either was far greater than that of running DOS. Enter MINIX, an operating system developed from the ground up by Andrew S. Tanenbaum, a college professor. MINIX was part of a lesson plan used to teach students the inner-workings of an operating system. Tanenbaum had written a book on MINIX called “Operating System” and anyone who had picked up a copy would find the 12,000 lines of code that comprised MINIX itself. This was a big issue; due to the fact that all know (well published) operating systems to that point had been well guarded by software developers, thus making it difficult for people to truly expand on operating system mechanics.
Freedom is often spoken of in what can be referred to as a loose sense of the word. One country has more freedom than another; a twenty-one year old has more freedom than a fifteen year old. What exactly does this word mean? For different people it may mean different things, but there has to be an equilibrium that can be reached in order to determine the meaning of freedom itself. In one form, freedom can mean that a person has "exemption from an obligation."* If only the root (free) is looked at, it can be interpreted that one is "not under the control or power of another."*
Linux has long been one of many operating systems that have been out to prove its worth in all types of environment. It is currently being considered for enterprise network purposes as well as data centers where it implies servers, workstations and any mainframes as needed. Choosing what operating system to use, whether it is open source or not, can be difficult, though. This paper projects the advantages and concerns of choosing an open source solution like Linux as administrators and users are becoming more aware of Linux running on both server and desktop systems. It is quickly being adopted in an ever increasing number of global corporations and government agencies.
A Terminal Operating System, or TOS, is a key part of the supply chain and primarily aims to control the movement and storage of various types of Cargo in and around a Container terminal or Port. The systems also allow the users to make better use of your assets, labor and equipment, plan your workload, and get up to the minute information which allows for more timely and cost-effective decision making. (From Wikipedia,)
The significance of the role of the Operation System (OS) in the overall Information Technology employment sector cannot be undervalued. Indeed, it is hard to talk about technical skill-sets or the practical application of such skill-sets without at least some underlying understanding of their context within a computer operating system environment. From hardware specifications and requirements, user technical support, system administration and security, to software development and system implementation, operating systems are an integral part of the information technology and computing world in all its aspects, and it is difficult to form a concrete demarcation between specialized careers in this industry and the concept of the computer operating system.
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
