...SUITABLE OPERATING SYSTEM FOR AN ORGANISATION An operating system (sometimes abbreviated as "OS")1 is the program that, after being initially loaded into the computer by a boot program, manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface such as a command language or a graphical user interface (GUI). How operating system works? When you turn on your computer, it's nice to think that you're in control. There's the trusty computer mouse, which you can move anywhere on the screen, summoning up your music library or Internet browser at the slightest whim. Although it's easy to feel like a director in front of your desktop or laptop, there's a lot going on inside, and the real man behind the curtain handling the necessary tasks is the operating system. Most desktop or laptop PCs come pre-loaded with Microsoft Windows. Macintosh computers come pre-loaded with Mac OS X. Many corporate servers use the Linux or UNIX operating systems. The operating system (OS) is the first thing loaded onto the computer -- without the operating system, a computer is useless. More recently, operating systems have started to pop up in smaller computers as well. If you like to tinker with electronic devices, you're...

...The Purpose and Functions of an Operating System Describe the purpose and functions of an operating system. Explain at least five differences among Windows, Linux, and Mac OS X operating systems. WINDOWS Operating System 1. Windows is the most commonly used operating system on client computers. It is estimated that up to 90% of client computers use one of the various Windows 2. Windows incorporates many applications for the end-user including a web browser (Internet Explorer), a word processor (WordPad), a command-line interface (Command Prompt), a file-managing application (Windows Explorer), and much more. Some end-users also make extensive use of Microsoft Office (Word, Excel, Outlook, PowerPoint, and Access) and many other third-party applications. Because Windows has the highest saturation in the market, third-party application developers focus the most on compiling programs that run effectively on Windows. 3. Windows XP was the legacy of Windows operating system, but after April of 2014 Windows XP will not been longer supported by Microsoft. 4. Widows Vista was supposedly the next generation of Microsoft replacing Windows XP, but did not did very well after their release in the market. 5. Latest Versions Windows 7 and Windows 8 has been gaining popularity thru their users. Windows 7 minimum requirements compare with other System Requirements succeed much better than the rest of the Microsoft operating system for Windows. Windows 7 has a processor...

...Operating Systems and Windows What is an Operating System? •The most important program that runs on your computer. It manages all other programs on the machine. •Every PC has to have one to run other applications or programs. It’s the first thing “loaded”. Operating System •It performs basic tasks, such as: •Recognizing input from the keyboard or mouse, •Sending output to the monitor, Operating System •Keeping track of files and directories on the disk, and •Controlling peripheral devices such as disk drives and printers. Is There More Than One Type of OS? •Generally, there are four types, based on the type of computer they control and the sort of applications they support. 1.Single-user, single task This type manages the computer so that one user can effectively do one thing at a time. Types of Operating Systems 2. Multi-user, multi-task Allows two or more users to run programs at the same time. Some operating systems permit hundreds or even thousands of concurrent users. Types of Operating Systems 3. Real Time Operating Systems RTOS are used to control machinery, scientific instruments, and industrial systems. There is typically very little userinterface capability. Resources are managed so that a particular operation executes precisely the same every time. Types of Operating Systems 4.

...there are people that are still clueless on the operating system. It is different, exciting when a new and advance system comes out. But some of us are so confused when it comes to the basics of new technology. Operating systems are programs which manages the computer’s hardware. The systems provide a basic for the applications programs between the computer user and its hardware. When looking, there are so many different types of operating systems that are available. The four main operating systems that are used are Windows, Mac, UNIX, and Linux. For every computer there are many different items that make the system a whole. When it comes to the different operating systems there are different features available, even though when you think of computers a person might think security will all be the same but there are difference between each one. As you read more you will understand the security and the difference between a MAC, UNIX/LINUX and Windows systems and how each one works. Access control goal is to protect a resource from unauthorized access while facilitating seamless and legitimate use of such resources. Presently, each day users hold the need to access to those resources through a broad line of devices, such as PCs, laptops, PDA, smartphones and kiosks. Most organizations need to provide protection for their files and allow the correct people to access. The fundamental goal of an Access management system is to maintain confidentiality of user information...

...some type of computers. Computers are utilized at home and at work, for amusement, information source, and as apparatus to leverage comprehension and aptitude. It is understood whenever any person sits down to use a computer and/or workstation that it will function with some type of graphical user interface. It is expected to interact with it mainly by use of a mouse, initiates programs by clicking on icons, and controls an assortment of windows on the screen using graphical controls. But this was not always the case. Why did computers come to implement the GUI as their most important method of interaction in our day? According to TechTarget (2011), GUI is an acronym for Graphical User Interface, what mainframe types call the system of icons, taskbars, and other objects that computers used to exhibit and access information (p.1). Reminiscent of a lot of progress in regards to the history of computing, some of the thoughts for a GUI computer were thought way before the technology was even obtainable to fabricate such a device. One of the first people to express this thought was Vannevar Bush. In the 1930s, he wrote of a device called "Memex," which he visualized a desk with two touch screen graphical displays and a keyboard. It would permit the end-user to access the knowledge by means of a correlation that is very similar to how hyperlinks work. At this point, the digital computer had not been invented, so there was no way for such a device to actually work until...

...Mac Memory Management For rough draft Mac OS is available on two processor architectures: the Motorola 68k series and the PowerPC. Mac OS has a flat address space, shared between all processes. There is no per-process memory protection. Application code runs in supervisor mode, so there is no instruction protection. Mac OS has virtual memory, in the limited sense that a larger fixed address space can be simulated, by storing the entire address space on disc. This size of this address space is fixed at boot time. The lowest part of memory is occupied by the system partition. This contains some system global values which applications should not access directly, although there is nothing to prevent them doing so. Historically, the Mac OS used a form of memory management that has fallen out of favor in modern systems. Criticism of this approach was one of the key areas addressed by the change to OS X. The original problem for the engineers of the Macintosh was how to make optimum use of the 128 KB of RAM that the machine was equipped with. Since at that time the machine could only run one application program at a time, and there was no fixed secondary storage, the engineers implemented a simple scheme which worked well with those particular constraints. However, that design choice did not scale well with the development of the machine, creating various difficulties for both programmers and users.

...Operating Systems When you purchase a computer or mobile device, it usually has an operating system and other tools installed. As previously discussed, the operating system and related tools collectively are known as system software because they consist of the programs that control or maintain the operations of the computer and its devices. An operating system (OS) is a set of programs that coordinate all the activities among computer or mobile device hardware. Other tools, enable you to perform maintenance-type tasks usually related to managing devices, media, and programs used by computers and mobile devices. Most operating systems perform similar functions that include starting and shutting down a computer or mobile device, providing a user interface, managing programs, managing memory, coordinating tasks, configuring devices, monitoring performance, establishing an Internet connection, providing file management and other device or media-related tasks, and updating operating system software. Some operating systems also allow users to control a network and administer security. Although an operating system often can run from a USB flash drive, media in an optical drive, or an external drive, in most cases, an operating system resides inside a computer or mobile device. For example, it is installed on a hard drive in a laptop or desktop. On mobile devices, the operating system may reside on firmware in the device. Firmware consists of ROM chips or flash memory chips that store...

...NT1110 Unit 10 Analysis – Repair Shop A computer repair shop chooses to back up the user’s data if there is an issue with the owner’s computer software. Then they just reinstall the operating system. What the computer repair shop does not do is reinstall the user’s applications. There are good and bad things about doing business this way. Some of the pros are it is less time consuming, all of the users pictures, music, videos, and documents will be backed up, and the computer will end up getting fixed. Doing it this way is less time consuming and that is both good for the computer repair shop and for the customer. Having everything backed up and the computer getting fixed are probably the two most important things to the owner of the computer. Despite all of the good things of fixing the computer of software problems by backing up the computer and reinstalling the operating system there still are some cons. There are not really any cons for the computer repair shop. However, for the user they might not like the fact that the person repairing the computer will not reinstall the user’s applications and programs. A user who just uses their pc for browsing the internet and checking emails will not need a backup or any applications reinstalled. Someone who needs their documents for work will need all of them backed up but will probably not need their applications installed for them because they can just do it themselves. I am sure the repair shop can install the users programs...

...To create a virus, a user or attacker needs to create a code. In this code the attacker needs to express what type of virus, he/ or she wants to use. Once the attacker determines what type of virus is going to be used, then they must determine who they want to attack. Lastly, ask what type of data they want to gain from the attack. People write computer viruses. The person has to write the code, test it to make sure it spreads properly and then release it. A person also designs the virus's attack phase, whether it's a silly message or the destruction of a hard disk. . There are at least four reasons why this is done. The first is the same psychology that drives vandals and arsonists. For some people, that seems to be a thrill. If that sort of person knows computer programming, then he or she may funnel energy into the creation of destructive viruses. Secondly the reason has to do with the thrill of watching things blow up. Some people have a fascination with things like explosions and car wrecks. Creating a virus is a somewhat like that, it creates a virtual bomb inside a computer, and the more computers that get infected; the more "fun" the explosion. The third reason involves bragging rights; some people enjoy the status it holds. Certain types of programmers see security holes that could be exploited, and are compelled to exploit the hole themselves before someone else beats them to it. The reason that drives many people on a day-to-day basis to commit crimes, get easy cash...
