In your work this week, you have been introduced to Linux by logging in to the virtual desktop and working through the individual assignment. In your own words (not a rehash of the text or internet sources), what is a "shell?" Why are they important in an UNIX or Linux environment? Describe at least two elements of the shell that make it important in the Linux and UNIX environments. Your answer should be at least 250 of your own words.

In the article, “Should You Adopt Open Source Software?” by Ven, Verelst, and Mannaert, you read about some of the pros and cons of adopting open source software in an IT environment. In your own words, describe why you would or would not adopt open source software should you have the opportunity. Provide at least one concrete example that supports your opinion. Your answer should be at least 250 of your own wods

Check out the website: http://lwn.net/Distributions/. You’ll note that there are many, many versions of UNIX and Linux that you could implement for your home or work use. Why do you believe there are so many varied versions of this operating system? What could be the advantage to having so many different versions available? What could be a disadvantage? Provide an example to support your opinion. Your answer should be at least 250 of your own words.

Most of the time, the words UNIX and Linux are used interchangably. While this is convention, there are differences between the two operating systems. What do you think are three differences between UNIX and Linux? Describe each and discuss why the difference may be important to an organization considering implementing either UNIX or Linux. Your answer

should be at least 250 words.

Throughout this course, and through your own research, you’ll hear how one of the hallmarks of UNIX is its “out of the box” security. Whether this is a fact or not depends on who and when you ask. You can read an overview of UNIX Security here: http://www.kernelthread.com/publications/security/tunix.html. CERT (Computer Emergency Readiness Team) also has published a checklist that UNIX administrators can use to monitor and enhance the security of their UNIX systems at http://www.auscert.org.au/5816.

UNIX has been around since the late 1960s. Given the long history of the operating system, I would like you to read the Bell-Labs article on the history of UNIX, located at:

In your opinion, what are 3 key points in the timeline of UNIX development? What do you think the impact of those points are on the current status of UNIX? Your answer should be at least 250 words.

You've read that one of the hallmarks of the UNIX operating system is the ability to modify the source code of the operating system (this holds true for Linux as well). What are two advantages to being able to modify the source code of the operating system? What are two disadvantages of being able to modify the source code of UNIX? Give an example of each.

For use in the weekly individual assignments, and to get a feel for what the UNIX or Linux of today looks like, we have been using Red Hat Linux 5. By this time, you may be considering investigating other versions of Linux. For this DQ, I'd like you to take a "Linux Distribution Chooser" test. It is 6 questions long.

The chooser is here: http://desktoplinuxathome.com/distro.html

Share with us the answers you chose for the questions, and the resulting top 4 distributions. Are any of your results ones that you are familiar with? Were you surprised at the results?

One of the biggest "complaints" people have of Linux is that there are few commercial applications available to compete with what is available in their current operating system. Pick two application categories (such as: Email, Word Processing, Spreadsheet, Money Management, Graphics, Music, Project Management) and locate an open source alternative for each. Give an overview of each product (brief - but at least a paragraph), then give several (say 3) reasons why the open source product meets many (not necessarily all) of the same needs as the equivalent traditional popular application.

One of the largest (literally) uses of UNIX and Linux are for powering the world's supercomputers. Supercomputers are used mainly to simulate and perform large mathematical calculations. My favorite is the Earth Simulator in Japan - I love the idea of simulating Earth's conditions. It used to be in the top 5, and has now fallen to 68th in power and capability.

After three weeks of working on the Red Hat system, you have now had a pretty good opportunity to use a command line interface (CLI). Compare and contrast using the command line versus a graphical user interface (GUI) for system administration functions. What are at least two advantages and disadvantages of each? Your answer should be at least 300 words.

Attached to this DQ you will find a somewhat dated, but still useful, lecture I used to use in class which focuses on viruses and antivirus for UNIX/Linux operating systems. Each of the antivirus programs mentioned in the lecture is commercial - there is no mention of open source antivirus options. Why do you think this is? In at least 250 words, give three reasons (and support them) why open source antivirus technology has been slow to develop.

In chapter 16 of our "Beginning UNIX" text, you read about networking protocols available in UNIX, and how those protocols are used to power the internet. In your own opinion, what are some of the reasons why UNIX® Internet commands have remained mostly the same since the advent of the Internet? Your answer should be well supported and at least 250 words.
