...Chapter 1, pp 20-21, Exercises 1, 4 1. What is free software? List three characteristics of free software. Free software is computer software that gives users the freedom to run the software for any purpose as well as to study, modify, and distribute the original software and adapted versions Three characteristics of free software are: The source code has to be distributed with the program, you cannot restrict people from redistributing modifying or using the software and users must be allowed to redistribute modified versions under the same terms and licensing. 4. What is the free software Foundation/GNU? What is Linux? Which did each provide? Who else has helped build and refine this operating system? Linux is the name of the operation system Kernel developed by Linus Torvalds which has since been expanded and improved by thousands of people on the internet. The free software Foundation (www.fsf.org) is the principal organizational sponsor of the G N U project. GNU developed many of the tools, including the C compiler that are part of the Linux operating system. Torvald’s kernel and GNU‘s tools work together as the Linux operating system. Chapter 2, p 50, exercise 1 1. Briefly, what does the process of installing an operating system such as Fedora/R H E L involve?

...NT1430 Final Review 1. Know what a swap partition is used for. a. The swap partition is an independent section of the hard disk used solely for swapping; no other files can reside there. Swap partition is used to turn the hard drive into extra RAM. 2. Know what an architecture is, and which are supported by Fedora. a. 32 and 64 bit b. Fedora CDs and DVDs hold programs compiled to run on a specific processor architecture (class of processors, or CPUs) c. There are several that Fedora supports: i. EM64T/AMD64 ii. A 64 bit distribution allows each process to address more than 4 gigabytes of RAM. iii. I383/i686 (Intel x86) iv. X86_64 (AMD64 and Intel EM64T) v. Mac PowerPC (PPC) 3. Know how the root of the file system is represented. a. The root is represented by a / b. Fedora uses the Filesystem Hierarchy Standard (FHS) file system structure, which defines the names, locations, and permissions for many file types and directories. c. The two most important elements of FHS compliance are: i. Compatibility with other FHS-compliant systems ii. The ability to mount a /usr/ partition as read-only. This is especially crucial, since /usr/ contains common executables and should not be changed by users. In addition, since /usr/ is mounted as read-only, it should be mountable from the CD-ROM drive or from another machine via a read-only NFS mount. 4. Know what the cp command is used for. a. The Linux cp command is usually used to copy files and copy directory in Linux...

...Windows 8 is a Microsoft operating system that is designed for home users as well as for business purpose. Its development started even before its predecessor’s release Windows 7 in 2009.Windows 8 is a system that is particularly orientated to touchscreen hardware. There are some important changes and additives that make it look and differently than the users are used to. For example, the Start menu is completely substituted by a Start screen that can be taken away from the desktop easily by touch screen pen and also by just a normal mouse or keyboard key combination. It contains all the important applications also the ones that are active at the moment. All the icons in the old version of the operating system are changed into tiles that can be juggled with. It can stay constantly on the screen or can be hidden.And now the most important that users expect to hear – when will it be available for the public and for what price? The official release date is the 26th of October, 2012. It was preceded by three pre-release editions while still being developed and tested for the period of the 13th of September 2011 until 31st of May 2012. There will be four editions issued on the market – two general editions just for conventional use, one Pro release of Windows most ardent devotees and Enterprise edition which is for business purposes. ² Windows 8 is the current release of the Windows operating system, produced by Microsoft for use on personal computers, including home and business...

...WEEK 8, ASSIGNMENT 2Ireti Kayode Strayer University | | CIS 175 Dr. William McConnell12/03/2013 | | | | | Ocper, Inc. Server Proposal Given Ocper, Inc.’s expanding network scenario there is a clear need to maximize the available resources between employees then it is appropriate to add additional servers to facilitate the sharing of files as well as the configuration of remote access services to allow for remote and secure working. In order to complement the existing network scenario this proposal is based around the configuration and deployment of Microsoft Windows Server 2012 as the network operating system. This is a stable and secure server environment which will allow the designated services to be configured and will equally allow for scalability while at the same time decreasing the overall maintenance and administration to support the network and associated servers. Given the size of the current organization and the IT systems at present, Windows Server 2012 Standard edition would be the most appropriate version for deployment as this will also keep the up-front costs down to a minimum – there is no requirement for the Enterprise Edition whose features will not be required in this implementation. One of the critical roles for the new server implementations will be that of a File Server capability – this can be easily configured within the Ocper, Inc. network through a Static IP address being assigned to this machine and then the...

...Updating From Microsoft Windows XP to Microsoft Windows 7 A lot of problems can arise when trying to update an older machine such as this from Microsoft Windows XP to Microsoft Windows 7. Microsoft has not made it easy for XP users to move to Win7. You won't be able to run the upgrade disk and have the newer operating system install on top of XP, leaving your data and programs in place. Instead, you have two options: 1. You can do a Clean install, in which you wipe the hard drive clean and install a virgin copy of Windows 7, then reinstall your software and copy your data back to the drive. 2. You can do a Custom install, in which your older setup is squirreled away in a folder called WINDOWS.OLD. This will include your program files, though you won't be able to run your software from there. It will also include data files, but you shouldn't rely on this as your sole backup strategy prior to upgrading. First and foremost When performing and update such as this: make sure that all hardware on the machine that is being updated is compatible and will meet Windows 7's minimum system requirements. A good way to do this is simply to go to the Microsoft website and download the windows 7 advisor at: http://windows.microsoft.com/en-us/windows/downloads/upgrade-advisor. This tool can be very helpful in determining if a system is capable of running windows 7. Some of the Windows 7 system requirements are: * 1 GHz processor (32- or 64-bit) * 1 GB of RAM (32-bit); 2 GB of...

...NTFS AND HYPER V The New Technology File System (NTFS) is the standard file structure for the Windows NT operating system. It is used for retrieving and storing files on the hard disk. The NTFS introduced a number of enhancements, including innovative data structures that increased performance, improved metadata, and added expansions like security access control, reliability, disk space utilization, and file system journaling. The NTFS replaced the OS/2 High-Performance File System and the Windows 95 file allocation table (FAT), which was used in MS-DOS and earlier operating system versions. NTFS is also used with Windows 2000, Windows XP, and Windows Server 2003.NTFS was initially designed for the Intel i860 XR processor released by Microsoft in 1993. Although IBM and Microsoft worked together to create the graphical operating system known as the OS/2, they disagreed on many important issues and they eventually separated. IBM continued to work on the OS/2, while Microsoft started working on Windows NT. The OS/2 HPFS had many new features that were also used with Windows NT. Both HPFS and NTFS share the same disk partition identification type code (07), which is unusual because there are dozens of codes available. The new reliable features of the NTFS include a fault tolerance system that automatically repairs hard drive errors without error messages. The NTFS also retains detailed transaction records that keep track of hard drive errors. This feature is beneficial in...
