If you're a techie entrepreneur creating a big e-commerce site, you may decide to buy a high-end Unix box to accommodate the volume and processing demands your bean-counters have projected for you. You'd run Sun Microsystem's Solaris software on it to power your Web server and e-commerce applications.
Or, you could opt to save a little venture capital and run Linus Torvalds' free operating system (and its accompanying free server apps) on a cluster of commodity Intel PCs.
The Linux OS is well-suited to small- to medium-sized operations, and is increasingly being used in large enterprises that would have previously considered Unix the only option. It has taken hold in Internet and e-commerce businesses, making the decision on whether to use Unix or Linux not as cut-and-dried as it may seem. A few years ago, the decision on whether to implement Unix or Linux was a no-brainer. Linux was an interesting academic project, but most people didn't consider it an option for a serious, commercial enterprise. How can it be that good if it's free? Isn't it just a toy for hackers and college students? But the maxim "you get what you pay for" doesn't really apply in the open-source world.
With major software vendors porting their applications to Linux, the OS has entered the mainstream as a viable option for Web serving and office applications and as a growing force in e-business (see Penguins running wild.)
Linux or Unix?
So when do you use Linux, and when do you use Unix? There are indeed some circumstances where Unix is the obvious choice, and Linux just won't do. "If you are talking about very large, massively symmetric multiprocessing systems, systems with greater than eight CPUs, you do need a full-blown Unix," says Jeremy Allison, Samba Team Lead at Fremont, Calif.-based VA Linux Systems. The current Linux 2.2 kernel does not scale well past four CPUs in a multiprocessing environment, but Allison says that the 2.4 kernel will scale significantly better--up to at least 16 CPUs. The 2.4 kernel, currently in beta, is due for final release in the first quarter of 2001.
Allison adds that a proprietary Unix system is probably better suited to a massive, single-box data center. "But there aren't that many applications that actually need something that large," he says. Moreover, many applications that do require mega-processing power can achieve that power through clustering, which both Unix and Linux do very well.
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 notion that software should be free is one that is highly critiqued within the technology industry. Free, as in the idea that users can obtain the source code for any given program, and modify and redistribute it as they like. Currently most all software produced is proprietary in nature. Corporations pay developers to create proprietary software that they then obstruct (so that no modifications can be made), and sell (to turn a profit). Richard Stallman has been fighting the idea of proprietary software, and specifically software ownership, for decades. Stallman holds the stance that software ownership is a detriment to society, and stifles innovation, education, and social cohesion.
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
The Linux operating system is the catchall term for the dozens of software stacks built around the free and open source Linux kernel. Clumped into distribution...
Microsoft, the leading manufacturer of personal computer software with its windows based operating systems and application software, has decided to expand its influence beyond windows into the Linux freeware operating system world. The means for entry into this rapidly growing segment of the server operating system market is through a takeover of the Red Hat Linux Company. Currently Microsoft Corporation now owns 51% of the stock for Red Hat Linux. This expansion directly into the Linux arena will provide Microsoft with the ability to attack competitors in the network server market with the Windows NT and Windows 2000 operating systems on one flank and with the extremely stable Linux operating system on the other flank. Microsoft expects to use this one-two punch to significantly gain market share in the server market and to shape the future of business LANs, WANs and the internet. Additionally, Microsoft expects to gain a controlling market share of the Linux office application suite wit...
During the time of 1969, two-computer scientist that worked with the AT&T Bell Labaratories made the decision to lead a time-sharing computer system named Unix. This system was later modified...
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.
The Operating Systems and Productivity Software Publishing Industry is primarily comprised of companies that develop and publish operating systems and productivity software for computers and servers. According to the 2013 IBIS World Industry Report, “an operating system is the interface with which computer users interact, and productivity software includes basic applications like word processors, spreadsheets and slideshow creation tools.” (IBIS 2013) Over the next five years, revenues for the $38.6 Billion industry is expected to grow at an annualized rate of 6.8% to $53.6 billion (IBIS 2012). This increase can be attributed to the overwhelmingly high demand for integrated cloud computing servers and the high end databases and software that accompany the new technology.
Then came Linus Benedict Torvalds. At the time he was a sophomore majoring in Computer Science at the University of Helsinki, his hobby also included computer programming. At 21 he found himself spending most of his time toying with computer systems, trying to see what he could do in order to push their limits and increase their functionality. The key missing in his tests was an operating system that had the flexibility craved for by professionals. MINIX was available, though it was still just a stu...
Against the above background, this report is intended to provide an objective review of where and how Linux might fit into your business related plans and activities moving forward. The aim is to deliver insight rather than recommendations – i.e. it is not my intention to either advocate or discourage desktop Linux adoption, just to help understand the potential benefits, issues and practicalities so the fit...
In this essay I will reflect on what I have learned in communication. I will use passages from the text as well as use information from the class discussions and activities. I will talk about face-to-face communication VS computer mediated communication, the different types of listening, what I think is the most important thing that I have learned this year, my group dinner, non-verbal communication VS verbal communication, and my group service learning project.
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
Artificial intelligence has been one of the main themes of science fiction. The idea that a machine or a computer could achieve or surpass human like intelligence, has intrigued people for almost the last century. To many AI can be a scary topic, for if a computer can outthink a human then there may not be any need for humans anymore. For others it is an exciting topic, many believing this is the future and how we will eventually be able to solve some of the universes most complicated problems. Though today there may not be a program that can match humans in the wide variety of task that makes us intelligent, there are some programs that have achieve human level performance in certain tasks
Thus, the communication module has taught that the process of communication is more than uttering a few words. The module has described communication as a process of establishing the relationship between the sender (speaker) and the receiver (listener). It is a two way traffic which should flow smoothly in order to achieve its goals. Moreover, the communication module successfully highlighted the ways and means to overcome the stumbling blocks in effective public speaking, active listening and teamwork. After attending the module, I intend to implement my acquired knowledge to effectively decipher the mental codes of the individuals to achieve the desired goals.
Communication is used in all aspects of our lives, and includes both verbal and non-verbal communication. “Communication skills are some of the most important skills that you need to succeed in the workplace” (How Good are Your Communication Skills, 2016). To help be successful with communication; one must know where they are at in their communication skills level, what gaps they may have, what training they may need, and any other improvement opportunities.
