Across
  1. 4. A program loaded into memory and running on the processor, performing a specific task.
  2. 5. server A server or hardware device that requests Internet resources on behalf of other computers.
  3. 6. platform A particular configuration and grouping of computer hardware, normally centered on and determined by processor type and architecture.
  4. 13. system (OS) The software used to control and directly interact with the computer hardware components.
  5. 15. A person who uses a computer.
  6. 17. OS X A version of UNIX developed by Apple for use on Apple desktop computers and servers.
  7. 20. A type of operating system that has the capability to provide access to multiple users simultaneously.
  8. 22. A type of operating system that has the capability to manage multiple tasks simultaneously.
  9. 24. A version of UNIX developed by Hewlett-Packard.
  10. 25. kernel A Linux kernel whose minor number (the number after the dot in the version number) is even and which is, therefore, deemed stable for use after widespread testing.
  11. 27. code The sets of organized instructions on how to function and perform tasks that define or constitute a program.
  12. 29. Windows The core component of the GUI in Linux.
  13. 30. One of the most popular and prevalent distributions of Linux, originally developed in Europe.
  14. 33. Protocol (IP) address A unique string of numbers assigned to a computer to uniquely identify it on the Internet.
  15. 35. Hat One of the most popular and prevalent distributions of Linux in North America, distributed and supported by Red Hat Inc. Fedora is a Red Hat-based Linux distribution.
  16. 36. Delivery Agent (MDA) The service that downloads e-mail from a mail transfer agent.
  17. 37. Passing Interface (MPI) A system that is used on Beowulf clusters to pass information to several separate computers in a parallel fashion.
  18. 40. A software operating system originated by Linus Torvalds. The common core, or kernel, continues to evolve and be revised. Differing OSS bundled with the Linux kernel is what defines the wide variety of distributions now available.
  19. 41. manager The software used to install, maintain, and remove other software programs by storing all relevant software information in a central software database on the computer.
  20. 43. TO A task-specific instruction guide to performing any of a wide variety of tasks; freely available from the Linux Documentation Project at www.linuxdoc.org/.
  21. 44. The central, core program of the operating system. The shared commonality of the kernel is what defines Linux; the differing OSS applications that can interact with the common kernel are what differentiate Linux distributions.
  22. 46. cost of ownership (TCO) The full sum of all accumulated costs, over and above the simple purchase price of utilizing a product. Includes training, maintenance, additional hardware, and downtime.
Down
  1. 1. number The number preceding the first dot in the number used to identify a Linux kernel version. It is used to denote a major change or modification.
  2. 2. service The additional functionality provided by a program that has been incorporated into and started as part of the operating system.
  3. 3. A mobile version of UNIX developed by Apple for use on iPhone, iPod, and iPad devices.
  4. 4. A set of instructions that knows how to interact with the operating system and computer hardware to perform a specific task; stored as a file on some media (for example, a hard disk drive).
  5. 7. number The number after the second dot in the version number of a Linux kernel, which identifies the certain release number of a kernel.
  6. 8. number The number following the first dot in the number used to identify a Linux kernel version, denoting a minor modification. If odd, it is a version under development and not yet fully tested. See also developmental kernel and production kernel.
  7. 9. The capability of computers to increase workload as the number of processors increases.
  8. 10. services The services that are used to access shared resources on a network server.
  9. 11. services The services that are made available for other computers across a network.
  10. 12. language The syntax used for developing a program. Different programming languages use different syntaxes.

  12. 16. interface The interface the user sees and uses to interact with the operating system and application programs.
  13. 17. Transfer Agent (MTA) An e-mail server.
  14. 18. An Internet protocol service accessed via an application program called a newsreader. This service allows access to postings (e-mails in a central place accessible by all newsgroup users) normally organized along specific themes. Users with questions on specific topics can post messages, which can be answered by other users.
  15. 19. Information and Computing Service (MULTICS) A prototype time-sharing operating system that was developed in the late-1960s by AT&T Bell Laboratories.
  16. 21. A major Linux distribution that is widely used in North America.
  17. 23. The programs developed and provided at minimal cost to the end user. These programs are initially free but require payment after a period of time or a certain amount of usage.
  18. 26. The first true multitasking, multiuser operating system, developed by Ken Thompson and Dennis Ritchie, from which Linux was originated.

  20. 31. A version of UNIX developed by Sun Microsystems from AT&T source code.
  21. 32. Mini-UNIX created by Andrew Tannenbaum. Instructions on how to code the kernel for this version of the UNIX operating system were publicly available. Using this as a starting point, Linus Torvalds improved this version of UNIX for the Intel platform and created the first version of Linux.
  22. 34. Torvalds A Finnish graduate student who coded and created the first version of Linux and subsequently distributed it under the GNU Public License.
