Unit Exercises
Chapter 1.
1. Free software is free, users can change code, and source code is available to anyone.
2. GNU/Linux is portable, is based on standards, is written in C, has a kernel programming interface, can support many users, and can run multiple tasks. For more information, refer to “What Is So Good about
GNU/Linux?” The source code for the operating system is readily available so that students can understand more easily how GNU/Linux works and can modify the code further to understand its operation and change the way it works. For more information, refer to “The Code Is Free”
3. Multiuser operating systems allows the multiple users to access the resources of a single systems at a time or at different time. allows many users to take advantage of the computer's resources simultaneously. some permit 100's to 1000 users to take advantage of the computer's resources simultaneously. They are successful because of the powerful, efficient, stable and secure operating systems like LINUX. it has a capability of providing each user the same data ensuring total privacy from each user even while accessed by 100's of users simultaneously.
4. The Free Software Foundation (www.fsf.org) is the principal organizational sponsor of the GNU Project. GNU developed many of the tools, including the C compiler, that are part of the GNU/Linux Operating system. Linux is the name of an operating system kernel developed by Linus Torvalds and expanded and improved by thousands of people on the Internet. Torvalds’s kernel and GNU’s tools work together as the GNU/Linux Operating System
5. Linux is written in C. It is successful because a programmer no longer has to resort to assembly language to produce code that would run well.
6. A utility (program), sometimes referred to as a command, is a program that performs a task that is frequently related to the operating system. A utility is simpler than an application program
