...Exploring Linux Operating Systems Linux is a computer operating system that was created and released by Linux Torvalds in October 1991. Linux was designed and released as a free, open source piece of software. This means that the code that makes up the program is freely available for anyone to copy, study, and modify the code in any way. This design was chosen to encourage the public to voluntarily improve the design and add functionality to the base software. This open source design is anecdotally considered to be a good thing, but has some drawbacks due to splintering, and lack of version control. Due to some of the splintering there are dozens of versions of Linux, most with similar functionality, while there are others that are designed for specific user types and use cases. Each “version” is called a Distribution. There are dozens, if not hundreds of these “distro’s” floating about. One of the most popular distro’s for the entry level user is Canonical’s Ubuntu Linux. This is a Debian based system with a rather simple user interface, and comes standard with a GUI and a host of tools that would make the system useable, and sufficient for most average users. On the other side of the spectrum there are targeted distro’s like KALI whose audience is more on the professional side. This particular distro is pre-loaded with tools that only a professional or an enthusiast would find useful at all. With such a wide range of options, there should be something for everyone...

...Running head: Linux Systems Exploring Linux Operating Systems Student College Exploring Linux Operating Systems Much like Windows OS and the OS X for the Mac, Linux is an operating system that was created by Linus Torvalds in 1991. Linux is traditionally a command line system as opposed to the GUI that many home computer users are more accustomed to. Linux uses a prompt where various commands and arguments are used to navigate the system and directories. One cannot point and click an icon in order to execute a program, in Linux the command line is like typing out the directions for your computer so it knows exactly where to look. Linux is being utilized in many different applications from business databases, cell phones, and even the New York stock exchange. Linux, however, is hardly considered a “personal computer” OS because of its limitations in personal computing. Although a Linux GUI desktop does exist, the command line interface is considered an advanced program and not for the faint of heart. Linux however holds many advantages in database software, server maintenance, code development and computer programming. The Linux “language” is close to coding language and the kernel is more secure than, say, the Windows Kernel. This advantage is encouraging to businesses and anyone else looking to keep or store sensitive data. Linux is a solid OS to use when handling such information when confidentiality is key. Like the other OS there are different means for file editing...

...An operating system (OS) serves primarily as a translator between the user and the applications and hardware of the machine in use. In this case the PC, tablet or mobile phone. The OS allows the user to easily visualize commands that prompt the software to carry out an array of functions, limited only by the hardware capabilities and the knowledge of its user. During the beginning stages of personal computer (PC) usage, IBM finalized a deal in the early 1980's with the most common household PC OS developer name, Microsoft. It's MS-DOS, then a command line user interface served as the principal design for Microsoft's home PC users released post Apple's Mac OS just 1 year prior. This decision was made after an irreconcilable deal for the 1970's CP/M developed by Greg Kildall. As MS- DOS gained recognition, the onset of home PC user OSs emerged. This report will provide an introduction to the top OSs commonly used in households today such as Mac OS X, Linux, Windows and some of their variants. The functions of these OSs vary in performance across the span of it's developers, however, are relatively the same. These similarities begin with booting the device, providing a Graphical User Interface (GUI) that appeals and adds ease of utilization to the user, as well as the management of system resource, input/output (I/O) and data. All are necessary for a positive experience from even the most novice of users. The similarities of the OSs are what group their developers together...

...Windows 7 I’ve had the chance to work with most mainstream operating systems that today has to offer and after exploring all the options I feel most satisfied with what Windows 7 has to offer. Whether you’re new to Windows or just upgrading, the benefits of switching are endless, ranging from new features to performance improvements, even the basic appearance. Windows 7 has many advantages over other operating systems. There are different versions that range from business to casual. All have their perks and range to different prices. You can pin programs, and files to the task bar, similar to other operating systems, but hovering your mouse cursor over the file or program in your task bar allows you to get a preview of that program or file. Another feature introduced is Windows snap. It allows you to drag a file to either side of your screen and snap it into place, allowing file comparison, along with multitasking. On top of the many features making Windows 7 better than most operating systems, is the hardware and software compatibility. After a fresh install of Windows 7, you can run Windows update and get all the drivers needed to run the hardware inside your computer. You can also run older applications that didn’t have compatibility in Windows Vista, but did in Windows XP. Another great new feature of Windows 7 is the security gains after upgrading from vista. User account control in Windows Vista was a huge hassle, and Windows 7 builds on that to make it less annoying...

And although the concept is still applied in current IBM systems, the popular concept of a VM has broadened and been applied to a number of areas outside of virtualization. Virtual machine origins The first operating system to support full virtualization for VMs was the Conversational Monitor System (CMS). CMS supported both full virtualization and paravirtualization. In the early 1970s, IBM introduced the VM family of systems, which ran multiple single-user operating systems on top of their VM Control Program—an early type-1 hypervisor. The area of virtualization that IBM popularized in the 1960s is known asplatform (or system) virtualization. In this form of virtualization, the underlying hardware platform is virtualized to share it with a number of different operating systems and users. Another application of the VM is to provide the property of machine independence. This form, called application (or process) virtualization, creates an abstracted environment (for an application), making it independent of its physical...

...integrative thinking. It is this discipline that is a defining characteristic of most exceptional businesses and the people who run them. Not every good leader exhibits this capability, nor is it the sole source of success for those who do. But integrative thinking tremendously improves people’s odds (possibilitats). Many great integrative thinkers aren’t event aware of their particular capability and thus don’t consciously exercise it. Opposable Thumb, opposable mind Red Hat faced what seemed like 2 alternative paths to growth. AS Red Hat looked to grow beyond its $1 million in annual sales, it could have chosen one of the 2 basic business models in the software industry. 1. classic proprietary-software model sold customers operating software but not the source code. These companies had wide profit margins because their customers, lacking access to the source code, were essentially locked into purchasing regular upgrades. 2. Free-software model: suppliers sold CD-ROMs with both the software and the source code.--> Prices were modest; and suppliers made money each time they assembled a new version from the many free updates by independent developers; but profit margins were narrow and revenue was uncertain. Bob Young didn’t like either of these models. (1st model: si compres el propi software I alguna cosa va malament, no pots fer res per arreglar-ho I 2nd: it might have offered reasonable returns in the short term but wasn’t likely to deliver sustained profitable...

...possible. According to the CNET, the Firefox OS is offered for $25 with a compatible smartphone. That is a huge difference in price when it is compared to the Ubuntu Touch, which is priced at $170 with a compatible smartphone. When factoring in the 170 Eduboost members, the total cost of Firefox OS phones would be $4,250 for the Eduboost; whereas, the total cost for Ubuntu Touch would be $11,900. Now while Firefox OS is offering their device for an extremely low price point for a smartphone, the people we are catering to would be able to increase the functionality and gain features and support in regards on promoting literacy.

...Exploring and Researching Your Chosen Profession By Robert Maddox EN1320 In this new age of the second industrial revolution, a time where skills in technology are essential to succeed in a competitive work force, cybersecurity is at an utmost priority for many companies and individuals alike. It's here where I feel I can make a truly important impact upon society, all while working with a sense of purpose and success. One can't watch television without the constant reminder of identity theft or devastating hacks by secretive individuals hidden behind false IP addresses and the like. Whether it's a commercial for credit scores and security or shows like Mr. Robot, cybersecurity is on everyone's mind, subconsciously or otherwise. And these issues are only going to increase as technology advances and the internet becomes more readily accessible to terrorists. As a veteran, my duty to protect American citizens did not simply stop when my contract ended with Uncle Sam. Ideally, I would accomplish this through the Federal Bureau of Investigations. There are many criteria to complete in order to accomplish this, and I am in no way close to this, yet one must start somewhere and this degree will be my first step. I have always been interested in computer technology, even if it merely stemmed from my long term relationship with video games. Rebuilding computers and achieving better performance came second nature to me and computers just make sense...

...We look for lessons in the actions of great leaders. We should instead be examining what goes on in their heads – particularly the way they creatively build on the tensions among conflicting ideas. How Successful Leaders Thınk by Roger Martin 60 Harvard Business Review 1179 Martin.indd 60 | June 2007 | Alex Nabaum W E ARE DRAWN to the stories of effective leaders in action. Their decisiveness invigorates us. The events that unfold from their bold moves, often culminating in successful outcomes, make for gripping narratives. Perhaps most important, we turn to accounts of their deeds for lessons that we can apply in our own careers. Books like Jack: Straight from the Gut and Execution: The Discipline of Getting Things Done are compelling in part because they implicitly promise that we can achieve the success of a Jack Welch or a Larry Bossidy – if only we learn to emulate his actions. But this focus on what a leader does is misplaced.
