Month 4: Networks and Server Structures

This month has been incredibly information intensive all throughout. When the teacher says, "Study the information you just learned every night," he really does mean it. I live with my boyfriend, and he has two Cisco degrees for networking, so I had an advantage there. The class dabbled into the OSI model, cryptography, binary conversion, subnetting and a whole lot more. The first test is the hardest. I haven't been able to keep my blog updated for the fact that I've been using all of my free time to study. But the first test is forty questions. There is a multitude of information, and it's extremely hard what to decipher is the key information. Because most of it is really important. Labs allow you to focus mostly on Terminal, Mac's Operating System, equivalent to Window's "Configuration." So I suppose I'll pick up where I left off.


Lab 5: Subnetting

For this class we were basically handed out a worksheet with an example on how to subnet and then were given four problems to complete. My suggestion to you is the you should learn how to subnet if you want an extra five points on the final.

Lab 6: SSH

In this lab we established a Secure Shell Handler between Full Sail's server and our computers. Again, really easy stuff.

Lab 7: Designing a Network

I wasn't here for this lab, I had a doctor's appointment on this particular day, but you had to design a functioning network. I used a private VPN to connect the Denver, CO Network and the New York HQ Network. I think I did a pretty decent job.



Lab 8: Deploying a Lamp Server

This class we installed a virtual Operating System and worked within Linux to create a LAMP Server (Linux Apache MySQL and PHP/Python/Perl). For whatever reason, it wasn't working properly for any of the students when we tried to connect via the browser. I'm not sure what was wrong, but we finished the assignment eventually.

Lab 9: Cisco

In Lab 9 we pretty much sat down and began to work on a Cisco chapter. It walked us through some of the basic principles of Networking. At the end, we took a test and had to send a screen shot of the results to our professor.



The Tests

Throughout the month we had two written exams, a midterm and a final, and on practical which was done in terminal. On the midterm, I ended up getting a 77%. You really do need to be careful on these midterms. The questions can get really tricky. For example...

The internet is a...
A) Packet switched network
B) LAN
C) MAN
D) Non Packet switched network

The thing that threw me off was that it was drilled into my head that the internet is a WAN, the biggest wide area network there is. It IS a packet switching network, but the singular form threw me off. Because I just thought it was a bunch of network"S" when really, it is a network of networks. So you really need to be sure when it comes to answering these questions.

Also, there are fill in the blank and True or False sections. You really, really need to know your stuff.

The second test, the Final, isn't so bad. It's pretty obvious that you need to know Protocols and the OSI model. Other than that, there are a few things here and there you'll want to study about, like VPN's, etc. but that'll make up about 10% of the whole test. Also. You NEED TO KNOW WHO INVENTED THE WORLD WIDE WEB. It is Tim Burners-Lee. Make sure you know that for both tests. On the final, if you didn't know that, you automatically missed two questions.

Anyhow, after you take the final, you get a break and then you come back for the Practical. The teacher gives you a packet of information that you can use for the practical, which really made it stupid easy. I was the first one finished. Basically, he gives you a compressed file. You need to upload the file to the server, decompress the file, and then organize the files correctly. You'll need to change the permissions of some files, move files, rename files, make directories, and a few other things. Once you're finished, you'll be able to connect to the server via your browser and you can double check your work with the images that he supplies for you. It's pretty easy as long as you know your stuff.

All in all, this is Networks and Server Structures. Buckle down. It's a looong ride. At least the teacher looks is funny.

Month 4: Networks and Server Structures

Lab 4: Subnetworks

Today was a bit rough. We learned how to Subnet. I'm not going to get into that, but it is probably the hardest thing we've had to learn this month, though with practice it gets easier. Basically for lab, we were given a Network Address and Class, and told we needed X amount of Subnetworks and X amount of Hosts per network. For that, we needed to find the Subnet ID's (up to a certain number), the Broadcast Address for those IDs and then the Range. So a lot of math was involved and you can't use your calculator. All in all it was a fun challenge, and now that I'm done, I'm leaving! So, I'll update you next time (after we have our Midterm).

Grades: Art History

Got our grades back from Art History earlier than usual. I really worked hard throughout the month, so I'm pleased with my 98 A+. Hopefully posting my work and showing the grades helps you to get an understanding of what it takes to pass these classes and were you should be as far as skill level when you come into the program.

Month 4: Networks and Server Structures

Lab 3: Searching Google

Lab three was fairly simple. We were taught how to use Google 'correctly.' Basically, we searched in formats like this:

Charles would like to buy a Cannon EOS 20D for under $500.00. He spends some time searching:

[canon]
[canon eos]
[canon eos $300..$500]
[canon eos $300..$500 site:ebay.com]
[canon eos $300..$500 site:ebay.com -450d -"eos 7"]
[canon eos 20d $300..$500 site:ebay.com OR site:amazon.com -450d -"eos 7"]


There were several questions like that on a sheet that we had to fill out. It was fairly simple.

Lab 4: Compressing and Addressing

This lab was also fairly simple. We worked in terminal and learned how to compress files, zip them, unzip them, and we even learned how to create .dmg files. You pay attention to the byte, kilobyte and megabyte information and report that on the worksheet they give you. The second part of that lab is more or less about finding the Network Address, the Broadcasting Address, the number of host bits, etc. Then there was a final section where it was matching a computer (in a diagram) to a description. Overall it was fairly easy.
