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 words

Check out the website http//lwn.net/Distribution
s/. Youll 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, youll 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/sec
urity/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
http//www.bell-labs.com/history/unix/
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.co

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.

Discuss three things that you will take away from
this course. You are free to discuss more, but
you must have at least three. For each of your
three things, describe why you felt it was
important and how you will use it as you continue
in your schooling or at work. Additionally,
include in your summary the discussion question
and assignment activity (or activities) you
enjoyed most. Your summary should be at least
300 of your own words.
