...one of the first computer operating system MS-DOS was and still is a single tasking operating system which created in 1980 and used up until 1990 when windows 3.0 came out which was considered a multi tasking but very slow the first pc was introduced August 12, 1981. It was the size of a portable typewriter and contained 40K of read-only memory and 16K of user memory, as well as a built-in speaker for generating music. But in time over the years the pc has developed smaller and faster by 1000’s fold. The task manager manages one program or many programs within a computer system simultaneously. A task management program in an operating system provides each task and interrupts the CPU operations to manage tasks efficiently. When you use the task manager to see all of the processes that are running you may see a process that is using a large amount of the CPU process and you can end the process in the task manager, the control over the CPU varies with each process some demand more power than others. There are many ways for a person to increase the power and capability of a computer for example one can upgrade the memory to a higher amount or upgrade the memory to a higher amount also. You can also use various programs that can improve the speed and performance of a computer, References Uknown, (2012, June 4). operating system.

Microsoft is a multibillion dollar organization and without them we would not be where we are today in the world of computers and technology. They have Cloud Computing, Bing search engine, and even Microsoft Dynamics, Lync systems, and even windows server which is used by IT specialists to increase the reliability of their server infrastructures. Each of these services is separately installed and you can buy them real cheap off their website at http://www.microsoft.com/government/ww/safety-defense/products/Pages/index.aspx. I chose Windows 8 because I am currently using it on my computer and I wanted to learn more about this specific operating system. I chose Ubuntu as my choice for Linux distributor because it was number one on the list and the first one I saw and I like the name. The name Ubuntu comes from African culture and it means “I am what I am because of who we all are”. Ubuntu on the other hand comes from...

Being that the company envisioned is, at this point, just a blueprint in our minds we will have to start from the absolute beginning with cost, performance, low downtime, training, and efficiency in mind. Step by step we will come closer to our end goal of a relevant architecture for a turnkey establishment that will continue into the next generation of technological advancements. With cost in mind either an open source operating system or volume licensing are the best options available. Also focusing on limited required training to show staff how to utilize the system places Windows 7 as the best option with the most functionality and least concessions. Windows 7 shows many improvements over its predecessors but does not share the learning curve that Windows 8 does. Windows 7 should be continually supported by Microsoft for years to come, unlike Windows XP, again making it a viable option to become a standard within the company without requiring costly operating systems upgrades for some time. For the best cost...

...time experience with a virtual operating system. I am currently running Windows 8 on my Asus machine the windows operating system was installed when I purchased my machine. For my Virtual operating system I chose an Ubuntu (64bit) operating system since I had no former experience with it I will be running the operating system on the Oracle VM Box Manager. My first experience with the Virtual Operating system is that I had to go to https://www.virtualbox.org/ to download the files to use to get the program for the virtual operating system. This took some leg work for me because I wanted to make sure that I was doing this correctly I didn’t want to accidently download a virus or something that would hurt my machine or break it so to speak. I consulted http://www.pythian.com and I found that the information there seemed legitimate so I went ahead with the downloading process. When you look on the site for the Oracle VM Box Manager they do include a very detailed manual so I found the correct install for my host which is windows it only took a couple of minutes for it to download. Once downloaded you go through the wizard which is pretty straight forward but I do highly suggest keeping the manual open for a reference so that you are able to know how much RAM to allocate your guest operating system. Once you have your virtual machine named and set up with a virtual hard drive you are ready to install your guest your operating system. Don’t worry there is a wizard for...

...fly without having to boot into a special disk utility. The Disk Management utility can only manage file systems compatible with Windows operating systems, such as FAT16/FAT32 and NTFS. Let’s say you want to make a partition smaller so you can create another partition on a hard drive this utility will allow you to do so. ScanDisk- A DOS utility included only in Windows 95/98/ME it is used to scan the suface ofthe hard disk and repair errors on the hard drive scan disk scans for lost clusters on the hard drive and turns them into .chk files. Chkdisk -is a command line program that also scans the hard drive and looks for lost clusters on the hard disk. It reports the current amount of free memory and disk space. If you use the chkdsk /f command which is Chkdsk with the /f = fix command it reclaims the lost clusters and turns them into .CHK files. FDisk- Is a program that runs in MS-DOS and non-NT versions of Windows and creates partitions on the hard drive Windows 95b first added support for FAT-32 partitions into fdisk. Before that it only supported partitions up to 2 GB using FAT-16. Disk Manager- A driver first introduced in 1985 from Ontrack Data Recovery, a Kroll Ontrack subsidiary, Eden Prairie, MN (www.ontrack.com) that allowed older DOS PCs with a 32MB disk limit to access larger drives. Since PCs made before 1994 may have had a system BIOS that did not support larger drives, the Disk Manager utility grew in popularity and was often bundled with new...

...Introduction My term paper is a study of memory management systems of two different operating systems. We begin with a brief introduction to memory management systems and then we compare the memory management systems of real life operating systems – Microsoft Windows and Linux. We will not be much interested in the performance characteristics of these systems in this paper; instead our focus will be on their design and architecture. Memory management system is important part of each operating system. The main function of this system is to manage the memory system of random access memory and the other storing devices which are available on the system. Main tasks that come under the memory management are allocation and deallocation of memory to the various processes running on the system. The memory management system should be optimized as its function affects the speed and the performance of the operating system. Memory management is the heart of operating systems; it is crucial for both programming and system administration. Learning objective Compare the memory management of windows with Linux. To know the similarities to know the differences in memory management and how memory management is an important part of an operating system.

...Operating System Comparisons PRG/355 January 14, 2013 Steven Kernan Operating System Comparisons Table of Contents Introduction 3 Memory Management 3 File Management 4 Security 4 Conclusion 4 Reference 5 Introduction An operating system (OS) is software that manages the hardware and software resources of a computer system. Basically an OS is a set of libraries or functions which programs may use to perform specific tasks relating to interfacing with computer system components (The Computer Technology Documentation Project, n.d.). Advantages and disadvantages exist in every operating system. Reviewed in this paper is a comparison of some of the primary responsibilities of popular operating systems. The review includes Unix/Linux, Mac, and Microsoft Windows operating systems. Memory Management An important function of the OS is to manage the computer systems memory. Programs, processes, and resource do not simply float around in memory haphazardly. Memory is shared among these processes and resources. Accordingly, managed by the OS is an organized structure of locating processes in computer memory locations. The two primary types of memory controlled by an OS are main memory and virtual memory. Main memory is… (need general definition). Virtual (secondary) memory is… (need general definition). Intended memory management requirements include relocation, protection, sharing, logical organization, and physical organization. Processes may...
