To use federated search, you must download or create XML files for specific sites called search connectors. 5. The only operating system edition that you can upgrade in place to Windows 7 Professional is Windows 7 Ultimate. 6. Upgrading a computer running Windows 7 starter to Windows 7 ultimate using Windows Anytime Upgrade requires------------------ megabytes of additional hard disk space.
Microsoft offers 2 physical CPUs per license where VM only offers one per CPU. Additional may be bought and stacked if more CPUs are needed. There are some additions that can be paid for, but more everything is include with the platform. VMware offers its platform but every addition there is a licensing fee attached, which is why the company makes additional money. For overall cost, in my opinion Microsoft has the advantage.
4. The Free Software Foundation (FSF) is a non-profit organization founded by Richard Stallman on 4 October 1985 to support the free software movement, a movement which promotes the universal freedom to create, distribute and modify computer software. GNU developed many of the tools, including the C compiler that are part of the Linux operating system. Linux is the name of the operating system kernel developed by Linus Torvalds, which has since been expanded and improved by thousands of people on the Internet. Torvalds’s kernel and GNU’s tools work together as the Linux operating system.
Linux OS is a derivative of the Unix OS. The Linux OS gain momentum through its progressive licensing which allow others to increase development with the OS. With overwhelming popularity from the creation of Linux OS, Unix OS reintroduce itself again. The functionality of both UNIX and Linux is very similar by both systems able to multitask, both systems are able to run on a variety of hardware platforms, and both are capable to use a command line. Linux is different through user friendly OS and by GUI.

Homework Assignment 2.1 Provide detailed answers to the following questions: Q1. What are the two predominant Linux desktops currently in use. A1. The two predominant Linux desktops currently in use for business or commercial use are Fedora and RHEL (Red Hat Enterprise Linux). These have shown to be reliable, stable and have regular updates with dependable support.
Thousands of people helped refine the operating system online and freely. Chapter 2 1.) Briefly, what does the process of installing an OS such as Fedora/RHEL involve? Installing Fedora/RHEL is the process of copying operating system files from a CD, DVD, or USB flash drive to hard disk(s) on a system and setting up configuration files so Linux runs properly on the hardware. Several types of installations are possible.
Again, the capacity range varies for some people have built 40 TB machines and some only have 2TB. With port replication and add-on hard drive controller cards there is hardly a limit on size. As far as fault tolerance, raid 50 is fairly stable if set up correctly, raid 10 is thought to be one of the best setups since more drives can fail at one time without data loss. NAS can be used for sharing files among multiple users / computers. It can also act as an external backup device if needed, thus by using a NAS you can easily get additional or extra storage for all your networked computers which can be quite cost effective in the long run and many NAS devices allow you to add additional space for more storage (Kumar) Now days there are so many different devices being used in our homes from all sorts of mobile devices to a range of gaming devices.
FAT32 file systems have a limited amount of disk size. FAT32 is a better choice if you want the OS to read the drive. If the machine is only a Windows OS, NTFS is perfectly fine, in a Windows computer system NTFS is a better option. A FAT32 mainly keeps track of the file locations. NFTS file systems offer enhancements the increase security and performance.
