1. What is free software? List three characteristics of free software. a. Free software, also known as software libre, or open source software, is a type of software that can be used and modified by the software owner, as well as redistributed. b. Free software is not synonymous with "freeware," which is software that is available for use free of charge, but may or may not be modified. This software is sometimes also free of charge, but sometimes requires a fee to purchase; the "free" in the name refers to the fact that it may be freely used and changed. 2. Why is Linux popular? Why is it popular in academia? a. It is very fast, easy to use and reliable. Writing programs and scripting on Linux is often times much easier than doing so on Windows as many of the users are that use Linux are computer savy but also because the framework that makes up Linux is completely open source, thus allowing programmers to program with Linux not around it. b. Students understand the source code for the operating system and how Linux works without complications. 3. What are multiuser systems? Why are they successful? a. A multi-user operating system is a computer operating system (OS) that allows multiple users on different computers or terminals to access a single system with one OS on it. b. Because you can add a user to your computer and have a different profile then another user, instead of buying another computer. This makes it cost effective. 4. What is the Free Software Foundation/GNU? What is Linux? Which parts of the Linux operating system did each provide? Who else has helped build and refine this operating system? a. The Free Software Foundation (FSF) is a nonprofit with a worldwide mission to promote computer user freedom and to defend the rights of all free software users. b.


It is the software on a computer that enables applications and the computer operator to access the devices on the computer to perform desired functions. Linux is the.
Linux is so great for a number of reasons: 1. ) Linux is free - Other OS's aren't. 2. ) The Linux kernel is much smaller and faster than other OS's. This extends the life of co mputer hardware. The requirements to run Linux are very lite compared to other OS's. This makes it a great choice for hardware that some would discard as old and slow. Linux can bring older computers back to life. 3. ) Linux is virus-resistant. Other OS's require anti-virus software, require that it update and scan periodically. It gives the user an incredible sense of freedom to know that the computer is only doing what the user is doing and isn't eating up memory and CPU cycles running extra programs to try and protect it. 4. ) Linux is Legos - You are free to choose almost any part of the system. If you don't like the GUI, you are free to change it. If you don't like the Word Processor, you are free to change it. Remove the parts you don't like and replace them. 5. ) Loading a Distro loads the OS (which already contains the drivers for the hardware) and whole host of software - The real programs, not demos or limited versions that you have to then pay to upgrade. 6. ) The security model is much more stout and is integrated into the kernel rather than being bolted on as an after thought. You need root privileges to install software, so viruses and malware cannot load themselves.


It also runs on the principle of "least privilege", meaning that you run normally as a user and then promote yourself to root to carry out administrative tasks. Other OS's pester the user with pop-up dialogs where a careless click can make the system vulnerable. 7. ) Linux is a server OS. If you want to setup a web server, you are free to do so. If you want to setup 10 websites, you are free to do so. There is no major distinction between a desktop OS and a server OS. Other OS's limit what the desktop version of the OS can do and force you to upgrade to a Server OS. 8. ) Linux gives you the freedom to try full-blown versions of free application software without first committing money to them. For instance, if I needed a Computer Aided Design (CAD) Program, I can try out several different CAD programs to see which one meets my needs before committing to one. 9. ) Linux is much more friendly to educational purposes. Its open-source code invites people to learn how things work and why they work that way. Other OS's buy their way into educational institutions to cultivate a new generation of users familiar with their software, but if a user wanted to see the source code, they say, "No, you're not allowed to see it, or learn about it. With Linux, you have a whole community willing to help you understand, write, debug, and even contribute to the project. 10. ) You should never HAVE to upgrade your hardware to run an Operating System. Note that this is BEFORE you have even loaded your applications, which is why most people use a computer - the applications. I hope that helps!
