Answer the following questions:

1. What is an argument?  Give several examples. 

   Arguments are the portions of the command that are part of the command itself.  the book uses this example:
   $ cp temp tempcopy
   The arguments are  "cp", "temp" and "tempcopy".  these arguments are in numerical order and are part of the execution of that command.  Sometimes a command requires a certain amount of arguments as exampled above, where the copy command requires the file your copying and the name your copying it to; but other commands may not require any.  Options are also considered arguments as well.  

2. Use the man pages to tell me two options for the ls command and what they do.

    -g  just like -l but does not list name
    -h, --human-readable   with -l, print sizes in human readable format (e.g., 1K 234M 2G)

3. Use the internet to look up "The Cathedral and the Bazaar" and tell me what it is and why it is important.

      The Cathedral and the Bazaar is an essay about the differences of two types of software development that was done with Linux.  The bazaar method is where the code that is used for making new releases of Linux available to everyone for viewing and given the ability to scour over the code searching for bugs and error's.  The Cathedral method is where the code is open sourced during the main releases only, but the code used in between releases is only available to the groups using it to develop the releases.

What is the Kernal?

After doing some reading, I've come to the conclusion that the kernal is most definitely the back bone of the operating system.  the kernal itself is not the source for the GUI, but it more or less enables the ability to have one.  The kernal is made up of many sub categories (System Call Interface "SCI"; Process Management "PM"; Memory Management "MM"; Architecture; Device Drivers "DD"; Virtual File System "VFS"; and the Network Stack).  The SCI is what enables the process and other functions of the kernal to be seen and used by GUI interfaces as well as used through the terminal.  The kernal also acts as the "middleman" between the hardware and the user interface using the architecture and device drivers to communicate throughout the kernal with processes that work through to the system call interface and to the user space. 

7 things you don't (but should) know about me

1.) I am currently in the military, have been for the past 7 years and some change.  I've loved a lot of things about it, and even hated a thing or two as well.  Overall, I wouldn't have it any other way though.

2.) I am attending TMCC to get a AAS degree in Computer Information Technology with my emphasis being in Servers and Networking.

3.) The only thing i know about Linux is that its open source and that a form of Linux is what Android is made from.  I know this only because I've goofed around on my phone and rooted it before.

4.) I am pretty tall compared to most.  I feel that me being 6'3" isn't that tall, but it is apparently a big deal to most others.

5.) I have a beautiful daughter that you see in my picture.  She is three in September and an absolute princess (even complete with the princess attitude :-P) that i raise completely on my own.

6.) I have been working with/on/around computers since I was about 10 years old.  I got my first computer at that time and really started getting into the MP3 craze that soon happened at that point.  My first computer was a compaq and died after leaving it on for more than 48 hours. 

7.) I love the Reno area mostly for its out doors and 24 hour lifestyle.  I love to Snowboard, Mountain Bike, Hike and venture around Lake Tahoe. 

I hope this helps everyone grasp my life a little, and if there are any questions, I would love to answer them.
