...Nick Scholes Explaining an OS and its Tools AIU Online 04/05/2014 In this document I will be explaining how to get a hard disk ready for an operating system and the utility tools that the Windows OS uses. Some the language might be a little technical but I’ll do my best to explain as much as I can as easy as I can. All this information is new to me so forgive me if I miss a step or skip over something. I’ll be trying to explain the tools and utilities in the Windows 7 and Windows XP. Accessing Disk Management in the Windows 7 OS from the computer management utility is very easy. There won’t be a shortcut to Disk Management in the start menu. The Disk management isn’t a program in the same ways that most software is. Let’s start with using the Start button and finding the Control Panel. Find the System and Security Link. If you have large icons or small icons the link won’t show up in the Control Panel. So what you'll do now is click on the Administrative Tools icon. Now once you’re in the Administrative Tools window, double click on the Computer Management icon. While in the Computer Management window, click on the Disk Management window that should appear on the right side of the window. It will now give you options to partition a hard drive, which means in the windows 7 OS that you divide the hard drive into parts and make those parts more accessible to the OS. Also in this window you can format a hard drive, which means that you delete any information on the drive...

...Windows 7 comes with a utility called the disk management utility which will allow you to create, resize, and delete hard disk partitions on the 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.

...from many other systems joined with numerous interesting plans and executions brought the advancement of Apple, Inc's. OS X family. In order to understand the progress of the older systems of OS X it is necessary to examine the upgraded technology and their interaction with other systems. To protect and troubleshoot the system it is necessary to know and understand the working of OS X technology. The open source core of the system is an operating system called Darwin. Darwin is a variant of BSD Unix running on the Mach 3 microkernel from Carnegie Mellon University and the Open Software Foundation (Singh, 2007). On top of Darwin, Apple utilizes both open source and proprietary code and builds a intricate and complex operating system which resembles the look of classic Macintosh computers with almost no similarity to recorded (1980s) Macintosh underlying innovation. In fact OS X is more compatible with its sibling UNIX systems and with Microsoft Windows than with past Apple computers. OS X is a UNIX 03 system as certified by the Open Group and recorded on their register (The Open Group, 2014). OS X moves forward rapidly and at some point dubiously, grasping new innovations, gadgets, and interfaces. For example:- Animations and graphics used in the system became more classy, then the system requirements started to upgrade hardware graphics capabilities. OS X has likewise exchanged architectures once in its concise history, from PowerPC to Intel, which was...

... Plug it into the AC adapter, and then boot it back up. Finally, press and hold “Command-R” (the “Command” and “R” keys at the same time) to start the restore process. Hold these keys until the Apple logo appears on the screen, and then release them. You will be taken to an alternative boot screen with a “Mac OS X Utilities” menu. Step 3 In order to complete a system restore, you will need to connect your computer to the Internet. Select “Wi-Fi” from the Utilities menu and find the router you will be using. Enter your Wi-Fi username and password to connect. Step 4 Depending on which version of OS X you are using, your Utilities menu will be slightly different. Look for either “Internet Recovery” or “OS X Recovery,” and select whichever one you find. This should present you with a “Reinstall OS X” option. Click on it, and then wait as your MacBook Pro connects to the Internet and gathers information on your laptop from Apple servers. You may be prompted to provide your Apple account information, including username and password. If so, provide it. In any case, this process will eventually reach the point where your MacBook downloads the latest version of OS X, as well as the standard programs that Apple includes pre-installed on every laptop. Your hard drive will then be automatically formatted, and the computer will restore itself to factory settings. Step 5 Once the reinstallation process is completed, you can either restart your computer, provide your Apple...

...devices. It consists of the operating system (OS) and utility programs. The operating system controls how your computer system functions. Utility programs are programs that perform general housekeeping tasks for the computer, such as system maintenance and file compression. 2. What are the different kinds of operating systems? Operating systems can be classified into four categories. Real-Time OSs (RTOSs) require no user intervention and are designed for systems with a specific purpose and response time (such as robotic machinery). Single-user, single-task OSs are designed for computers on which one user is performing one task at a time (such as PDAs). Single-user, multitask OSs are designed for computers on which one user is performing more than one task at a time (such as desktop computers). Multiuser OSs are designed for systems in which multiple users are working on more than one task at a time (such as networks)....

...(Capron, 2001), “An Operating System is the fundamental software that has the access to control all other software and hardware resources” (p. 65). It has control of every file, processes, session of memory and device. (Nickerson, 2001) stated, “The most centralized system software is the OS. Without it, PCs would be extremely hard to utilize.” (p. 31). It is specially designed to work for different types of computers. For example: desktop computer, laptop, tablet PC, handheld PC, etc. Generally, a personal computer (PC) is all-purpose computer. The size and the capabilities make it convenient for individuals, and which is intended to be operated directly by an end user. The different types of operating systems are, Windows, Linux, Mac OS, etc. and each of them have different versions. These advances in hardware and software technologies have increased demands for more advanced and better operating systems. Now, compatible companies such as Windows and Apple are coming up with newer generations in the OS field which performs more complex tasks compare to their previous generations. Operating systems have evolved through various stages and generations. Looking back into the history of OS, the first generations came out in the year 1940’s. The first electronic digital computer didn't have any operating systems or programming languages at that time, they were nonexistence. It was very primitive and programs were...
