LPI Linux Essentials 010 V1.6 - Chapter 3 Quiz

True or false: VMS was a common OS on x86 PCs at the time Linux was created.

False. VMS was an OS for minicomputers and mainframes when Linux was created. On x86 computers, DOS was the dominant OS in 1991.

True or false: Some DVRs run Linux.

True. Digital video recorders (DVRs) are specialized computers for recording TV shows. Some commercial DVRs such as TiVos, run Linux natively. DVR software for standard PCs, such as MythTV, which runs under Linux, also exists.

What type of multitasking does Linux use? A. Preemptive B. Multiuser C. Cooperative D. Single-tasking E. Single-user

A. Linux's multitasking is preemptive, meaning that the kernel can give CPU time to any process as it sees fit, potentially interrupting (or preempting) other processes. Thus, option A is correct. Linux is a multi-user OS, but multi-user is not a type of multitasking, so option B is incorrect. In a cooperative multitasking OS, applications must voluntarily give up CPU time to each other. Although Linux programs can signal the OS that they don't need CPU time, Linux doesn't rely exclusively on this method, making option C incorrect. A single- tasking OS can run just one process at a time, so option D is incorrect. A single-user OS can support just one user at a time. Such OSs can be either single tasking or multitasking, and in the latter case, can use either cooperative or preemptive multitasking. Thus, option E is incorrect.

The _____________ software package is an example of a web server written for the Linux server environment. A. MySQL B. LibreOffice C. Firefox D. GIMP E. Apache

Apache. The Apache software package is a web server program written specifically for the Linux server environment, taking advantage of how Linux handles processes and memory for multiple applications. Thus, Option E is correct. The MySQL program is a database server commonly used in Linux, not a web server, so Option A is incorrect. The LibreOffice package is a word processing program, not a web server program, so Option B is incorrect. The Firefox package is a web browser program, not a web server program, so Option C is incorrect. The GIMP package is a graphics processing program, not a web server program, so Option D is incorrect.

A _______________ computer is likely to run a word processor and web browser. A. server B. desktop C. distributed D. client E. laptop

B. A desktop Linux system usually utilizes a graphical desktop interface environment for running graphical programs such as word processors and web browsers, thus Option B is correct. Server computers typically don't utilize graphical desktops, making Option A incorrect. Distributed computers are typically servers, which don't utilize graphical desktops, so Option C is incorrect. A client computer may use a graphical desktop, but it's not required, so Option C is incorrect. A laptop computer may also utilize a graphical desktop, but could also be used as a text-only server, so Option E is incorrect.

Linux uses a(n)_____________kernel design, as contrasted with a microkernel design. A. exo B. monolithic C. hybrid D. distributed E. unified

B. The monolithic kernel design incorporates all of the kernel functions into a single program, whereas the microkernel design splits the kernel functions into separate smaller programs. Thus, Option B is correct. An exokernel design provide minimal hardware support in the kernel, relying on external programs for everything else, thus Option A is incorrect. A hybrid kernel are similar to microkernels, but rely on some external programs to operate, thus Option C is incorrect. The terms distributed and unified are not used to describe kernel types, thus Options D and E are both incorrect.

Which of the following is a characteristic of all open source software? A. The software cannot be sold for profit; it must be distributed free of charge. B. It must be distributed with both the source code and binaries. C. Users are permitted to redistribute altered versions of the original software. D. The software was originally written at a college or university. E. The software must be written in an interpreted language that requires no compilation.

C. The open source definition includes 10 points, one of which is that users may modify the original code and redistribute the altered version. Thus, option C is correct. Although all open software is available at no charge, nothing in the open source definition forbids selling it, and in practice, many organizations do sell open source software, so option A is incorrect. The open source definition requires distribution of source code but does not require distribution of binaries, so option B is incorrect. Although many open source projects began life in an academic environment, that's not a requirement for open source software, so option D is incorrect. The open source definition does not specify that either an interpreted or a compile language be used, making option E incorrect.

Which of the following programs is most likely to be installed and regularly used on a desktop computer that runs Linux? A. Apache B. Postfix C. Android D. Evolution E. BIND

D. Evolution is an email reader program. Such programs are commonly used in desktop environments, so option D is correct. Apache is a web server, Postfix is an email server, and BIND is a Domain Name System (DNS) server, which are all unlikely to be run in a desktop computer environment, making options A, B, and E incorrect. Android is the name of a Linux distribution for smartphones and tablets, not a program, so option C is incorrect.

A type of software that's distributed for free but that requires payment on the honor system if a person uses it is called ___________ . A. open source B. commercial C. freeware D. shareware E. virus

D. Shareware allows a program author to release the binary executable program to the public without payment but ask for payment if the program is used. Thus, Option D is correct. Open source software does not require a payment, thus Option A is incorrect. Commercial software requires an up-front payment, making Option B incorrect. Freeware doesn't require any payments at all, making option C incorrect. Viruses are not typically distributed as software packages, making Option E incorrect.

True or false: A Linux computer being used as a server generally does not require X.

True. Most server programs do not require the X Window System (X) GUI, so server computer administrators often disable X or even remove it entirely to save disk space and memory and to minimize the risk of security problems.
