Linux Operating System

Linux is an UNIX – like operating system that is largely POSIX compliant. Linux is being developed under the GPL and is freely redistributable in source code. This means that is an open source that means you can see the source code. The first Linux kernel was written by the Linus Torvalds in 1994 and is the core of the operating system.
There are 5 core Linux kernel sub-systems. First sub-system is called the Process Scheduler, which regulates processes to the CPU. The second sub-system is called Memory Manager, which controls memory matching and it also makes sure the processers do not overlap. The third sub-system is called Virtual File System, which controls the security of stored data and also controls the high-speed access. The fourth sub-system is called Network Interface, which provides network connectivity between machines. The fifth sub-system is called Inter-Process Communications, which enables concurrently executing processes to share common resources.
Linux has many different distros or versions of the operating system. There are 10 popular ones out there. Here they are arch, centos, Debi an, fedora, Gentoo, Linux mint, opens use, red hat, slack ware and Ubuntu. The most popular out these is fedora. Linux can be set up how you wanted. Here are some companies that are using Linux based operating systems. They are Netflix, IBM, Oracle and Red Hat. Then there are some web based companies that are also using Linux. They are Google, Facebook and Twitter to name a few. There is money and information based things that use this system. Here are just a few that use it the London Stock Exchange, The Chicago Mercantile Exchange, the New York Stock Exchange, and even the Tokyo Stock exchange. There are some of the most popular products that use this system. They include mobile phones, tablet computers, network routers, televisions, game consoles and all of the android systems on mobile devices.…...

Oceans Eleven Review

...inside your paycheck and an inferior good is something that you pay below what you normally would. In the movie they want Danny to a job for them but when he cant they must use the inferior person Linus (Matt Damon) instead. Of course the whole reason for the heist is so they can make money and buy more normal goods in their lives instead of settling for inferior goods. Sunk cost is a big part of Oceans eleven because anything they bought during the time of heist, if they get caught, would be useless. Elliot Gould’s character was supplying the money for the job and if they were caught that would be money he would never get caught. Opportunity cost is a big part of anything we do because it is just making choices. The three biggest decisions of the movie are Danny’s choice to do the heist, make Linus the lead for a short time and Tess deciding to be with Danny. Danny’s opportunity cost of the heist is either going back to jail that he just got out of or get thirteen million dollars from splitting the 150 million dollars thirteen ways. Since Danny could be recognized in the casino they had to use Linus instead as the main man to get them inside the vault. This shows opportunity cost because if they have Danny do it then he might get caught and completely blow the mission but if they use Linus then he might not be able to pull off the con. The last example is Tess’s decision to be with Danny. She had to choice between a good man that loved money more then her or Danny a......

Modular programming. Retrieved from Personal Learning Management As course assignments, assigned reading, assigned and interest-based research, and other learning activities are completed, the learner may recognize the economic value of what has been learned. Knowledge gained through learning can be forgotten if concepts are not reviewed on a regular basis. It is possible to design an application to record high economic value learning tasks and insights that will allow for periodic review. This application will help solve the issue of knowledge being forgotten by allowing the information and concepts to be kept in front of the individual for regular review. The application that must be programmed will be a simple user friendly app that will allow the user to see and record progress over a given class which will give the user the ability to not only see what has been done but to have it brought back to the forefront of what they already went over in course assignments, reading and researches for a particular class. So in essence the program will help each student record each task and can, ever so many days allow the student to review what they covered and done to keep the information fresh. The information that we will be recording is......

Research Paper

...History of Tablets The History Of The Tablet, An Idea That Steve Jobs Stole And Turned Into A Game-Changer (Bort, 2013). I am doing a research paper on the history of tablets. My question for this topic is whether Apple’s Ipad was the first tablet created or not. You will find out in the rest of this paper. Apple’s Ipad got most of the credited for killing the netbook market but it was not Steve Jobs’ idea (Bort, 2013). The first tablet was the Linus Write-Top that debuts in 1987. The Linus Write-Top revolutionized the way businesses check their databases. It is a “resistive” type of touchscreen in which voltage applies to the screen edges, and the stylus detects the voltage (Linus Write-Top, 2013). The Linus (“of or about lines”) converts your scrawls into perfect text of five characters per second (Linus Write-Top, 2013). It was an expensive piece of technology as most old computers were. The GridPad launched two years later in 1989. The military and law enforcement used it mostly while consumers ignored it because of the high price. The GridPad was the first touchscreen tablet that was portable. It was used primarily for experimental purposes and the like (GridPad, 2013). The United States military specified more rigidity than those sold to the public (GridPad, 2013). Microsoft’s CEO Bill Gates debuts its first tablet computer in 2000. It would become a big thing five years down the road as Bill Gates predicts. He was five years off. The device would feature......

Windows vs Linus

...Windows VS Linux. Ronald Prasad When it comes to computers, majority of the users tend to prefer windows based systems rather than Linux. While Linux has its own qualities like been open source licensed, Windows on the other hand is more user friendly and also has great Hardware supporting compatibilities. Linux is an open source licensed operating system, which basically means that it’s free for everyone to download, free of cost, and modify it without any need of a licenses. Since it’s totally free there is no guarantee of its reliability or customer support to help deal with technically problems. Whereas compared to Windows, which costs about $99-$199 for Windows 8 version, although it does not come cheap, but it provides a guarantee of its reliability and customer support. Windows operating systems are much more user friendly, especially the Windows 8 version, which has excellent user interface, which allows users to navigate, explorer, trouble shoot with very little difficulty. Whereas Linux has a very complex look and puts more emphasis on usage commands in Terminal Window usage instead if using the interface, e.g. To install updates on Linux, sudo apt-get upgrade command must be type in the Terminal Window whereas is Windows getting updates is easily done with just few mouse clicks in the Control Panel. Windows supports most motherboards, mice, hard drives, keyboards, network cards, DVD drives, flash drives and monitors. Since these hardware’s mostly comes with......

Mr Tee

...The history of Linux began in 1991 with the commencement of a personal project by a Finnish student by the name of Linus Torvalds to create a new free Operating System Kernel. He wrote the program specifically for the hardware he was using and independent of an Operating System because he wanted to use the functions of his new PC with an 80386 processor. The development of Linux was done on Minix using the GNU C Compiler. The GNU C compiler is still the main choice for compiling Linux today. The code however, can be built with other compilers, such as the Intel C Compiler. At first Linus Torvalds had wanted to call his invention FREAX, a part manteaux of “Free”, “Freak”, and “X” (as an allusion to UNIX). During the start of his work on the system, he stored the files under the name “FREAX” for about half of a year. Torvalds had already considered the name “Linux”, but initially dismissed it as being to egotistical. In order to facilitate the development, the files had to be uploaded to a FTP Server. Ari Lemmke, Torvalds coworker at Helsinki University of Technology (HUT) who was one of the Administrators for the FTP server at the time, did not think that “FREAX” was a good name. So, Ari named the project “Linux” on the server without consulting with Torvalds. Later, However, Torvalds consented to “Linux”. Torvalds first published the Linux Kernel under its own license, which had a restriction on commercial activity. The software to use with the Kernel was software......

Investigation Into Opensource Software

...Understanding Open Source Software Development Process Abstract: As the assignment requirement, we selected eclipse, Linux kernel and commercial software from the corporation of one member. It is the regret that we had not enough time to collect all statistics by ourselves, and instead of that, papers and blogs are the main resources for open source part in this document. The open source software is introduced before the commercial one. Keywords: development process, code ownership, defect density, bug lifetime Background: Linux Kernel In April 1991, Linus Torvalds, a 21-year-old student at the University of Helsinki, Finland started working on some simple ideas for an operating system. He started with a task switcher in Intel 80386 assembly language and a terminal driver. On 26 August 1991, Torvalds posted the following to comp.os.minix, a newsgroup on Usenet: I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386(486) AT clones. This has been brewing since April, and is starting to get ready. I'd like any feedback on things people like/dislike in minix, as my OS resembles it somewhat (same physical layout of the file-system (due to practical reasons) among other things). After that, many people contributed code to the project. Early on, the MINIX community contributed code and ideas to the Linux kernel. At the time, the GNU Project had created many of the components required for a free operating system, but its own......

Social Issues

...monopoly and substandard software, while Linux is based on free, open source and the concept of open standards, full disclosure and sharing. Microsoft attempts to discourage consumers from using the Linux solution by suggesting that the operating system is less than perfect, yet it remains blind to its own operating system's problems existent within Windows 95/98 and Windows NT.  It's a well-known fact that Microsoft dominate the software market despite these facts. Are they operating within legal and ethical boundaries? And is it possible that they could fall from grace because of this?  `When you say "I wrote a program that crashed Windows", people just stare at you blankly and say "Hey, I got those with the system, *for free*".'  (Linus Torvalds)  Introduction  Linux and Microsoft operating systems have been marketed very differently. The objectives of the two factions are very different indeed. One seems to be oriented towards market domination, market cornering and making the most amount of money it can, and the other towards creating a free, open source operating system. This may sound too simplistic with the two extremities, and may be a bit more complicated. This report will investigate into the differences in the way that the Linux and Microsoft operating systems have been developed and marketed, and how Microsoft rose to fame, and the possibilities of it's fall from grace.  Open Source  The significant difference between the Linux and Microsoft......

Technological Innovations

...Project 2 – Technological Innovations Nathan Brenner Westwood College 2014/05/09 SOCS-299 Abstract The open source software Linux, was introduced in 1991, by Linus Torvalds. He developed the UNIX based operating system because, the education oriented operating system he was working with was not meeting his needs. Linux has grown to be an innovative powerhouse, because Linux is so versatile it can be used in hundreds of applications and shows no signs of age or being outmoded. Technological Innovations The financial burden put on college students is staggering. However, there is one corner that can be cut when deciding what kind of operating system for your computer to purchase. Most people are mundane and choose whatever is pre-installed on the computer they are purchasing, but did you know there is an alternative? When you think of a computer operating system, what is the first thing that comes to mind? Windows? Apple? Did you know there was a third alternative? I am talking about the open source software known as Linux. What is Linux? The actual definition is “a freely-distributable open source operating system that runs on a number of hardware platforms” (webopedia, 2014). The technological advantage that the open source software Linux has given to the world is immense. This open source software has come a long way since its inception in the early 1990’s, and has grown to be the most versatile open source operating system to date. Along with its......

According to his brother, Linus, he is in and out of many relationships and has attempted several different career paths but never completes anything. Sabrina is sent to Paris for a two-year fashion internship at Vogue by her father, in hopes that she will get over her infatuation for David. Sabrina returns to Long Island as an attractive, sophisticated woman. David, after initially not recognizing her, is quickly drawn to her despite being newly engaged to Elizabeth Tyson, a doctor. David's workaholic older brother Linus fears that David's impending wedding to the highly suitable Elizabeth might be endangered. If the wedding were to be canceled, so would a lucrative merger with the bride's family business, Tyson Electronics, run by her father Patrick. This could cost the Larrabee corporation, run by Linus and his mother Maude, in the neighborhood of a billion dollars. So Linus comes up with a plan and tries to redirect Sabrina's affections to himself, and it works. Sabrina falls in love with him. In the process, Linus falls in love with her. Unwilling to admit his feelings, Linus confesses his scheme to Sabrina at the last minute and sends her back to Paris. However, he is induced to pursue her there after a scolding from his mother and a newly aware David, who steps into his shoes......
