Match each item with a statement below.

Describe a system service. Every time you run an application, the OS starts a process called a “system service” to handle it. The process runs in the background and carries out application-related tasks. Some system services start automatically when a computer is booted, such as the Network Service in Linux, which handles all network interfaces.
Identify the main idea behind the General Public License (GPL) and list three characteristics of software developed under the GPL. The main idea behind the GPL stems from Richard Stallman’s philosophy that software should be free, by which he meant having the freedom to change the source code. The GPL states the following: · You can use, view, and change the source code. · You are able to redistribute the software and sell it for profit. · If you decide to sell the software, you must make the source code available.
Provide a brief overview of SUSE. SUSE was developed in Germany in 1992 by Hubert Mantel, Burchard Steinbild, Roland Dyroff, and Thomas Fehr. The name “SUSE” is an acronym for “Software und System Entwicklung” (Software and System Development). It became a top Linux seller in Europe and was eventually sold to Novell for $ million. Novell is a multinational software and services corporation that provides support to more than 50,000 companies in 43 countries.
Define the Linux modular architecture and discuss its advantages. Linux is a modular system, which means all its components are separate from one another. This design makes it possible for different teams to develop components that don’t affect one another. For instance, one team might update the kernel, and another team might create applications. In fact, you can create applications that meet your own needs or even contribute to the Linux kernel. A Linux distribution, such as openSUSE 11.2, consists of all the Linux components put together and released as one OS.

Describe an advantage of having a multiuser system. One advantage of having a multiuser system is eliminating the need to back up multiple computers. If all data and applications are on a server, for instance, the computer staff needs to secure and back up only that system.
Describe the disadvantage of having a multiuser system. The disadvantage of having a multiuser system is that it creates a single point of failure. If the multiuser system goes down, users can’t do their work.
Describe preemptive multitasking. In preemptive multitasking, the scheduler decides when a process stops and another process starts. It assigns a certain amount of time to each process, which is referred to as “timesharing.” The scheduler starts high-priority processes sooner, giving them more time. Users don’t see this timesharing or notice interruptions in processes because the scheduler resumes stopped processes rapidly.
Describe the BASH shell. Bourne Again (BASH) is the default shell in openSUSE and most other Linux distributions. Part of the Free Software Foundation’s GNU Projects, it has a history function that can also be used to remember commands entered in previous sessions as well as the current session.

How does YaST assist with the Linux installation process? YaST guides you through the installation process by analyzing your current system components and displaying settings based on the analysis. During installation, YaST displays an overview of installation steps with help documents for each step.

Why is it important to check your system configuration before installing openSUSE? Your system configuration determines how you install openSUSE. For example, you load different software applications during installation if you have a laptop rather than a desktop. You also load server applications if your system is to be used as a server or desktop applications if your system is to be used as a personal computer. To a beginner, these different configurations might sound a bit intimidating, but YaST is an excellent tool designed to help you perform these tasks easily.
List three benefits of using virtualization in a network. Some benefits of using virtualization in a network include the following Allows running multiple OSs on one machine · Gives you the opportunity to test applications before actually installing them on a host machine · Reduces costs by decreasing the physical hardware that must be purchased for a network · Offers the chance to experiment with untested programs without infecting host machines with viruses or other malware
Provide a brief overview of VMware Player. VMware Player 3.1.5 is a free application that enables you to create, configure, and run virtual machines on a Windows or Linux system. With VMware Player installed, a guest OS can access all the host machine’s hardware, including printers, network interface cards (NICs), and USB drives. A major benefit of having VMware Player is being able to create virtual machines to test different OSs and applications without concern about damaging the host.
Describe the desktop environments available with openSUSE. OpenSUSE offers GNOME and KDE as desktop environments. You use the Desktop Selection window to choose which environment you want. If you select Other, three additional options are displayed: XFCE desktop, Minimal X Window, and Minimal Server selection (Text Mode). You might use one of these options if you don’t want a lot of default software packages installed on your computer. For instance, if your Linux system is being used as a server, you don’t need many of the graphical functions included with a desktop.
Explain what Logical Volume Management (LVM) is and the benefit of using the feature. Logical Volume Management (LVM) is used to create virtual partitions that can span physical hard drives, which means you can resize partitions later, if needed. For instance, if you accept the default Partition Based option and later your /home partition fills up, you would have to delete files to free up space in that partition. With the LVM option, you can increase the size of the /home partition by resizing seldom used partitions such as /tmp and /share.
