CST 311 - Module 1

 Week 1,

We begin yet another course, only this time the topic is about computer networks. I am generally excited about to learn more about computer networks and the internet. Everything is connected to the internet these days and now I get to learn how to utilize and understand it.

Like what is stated above, this is the first week, so the material is aimed at getting us students to become familiar with the software being used in the course, such as using multiple virtual machines, Python, and Wireshark to "sniff packets" being sent to and from the selected VM or host computer. Besides the software, we were also given textbook material to read ("Computer Networking" by James F. Kurose; Keith Ross) which introduced us to the basics of how the internet functions. Some notable takeaways from chapter one is that the network edge consists of hosts (basically clients and servers), access networks such as DSL, FTTH, etc., and the network core which is a mesh of interconnected routers which can utilize packet switching or circuit switching. One especially notable takeaway involves calculating end to end times from one source to another, as well as the involved propagation delay/speed and transmission delay/rate. 

There are of course other bits of information that are just as important, but then (like always) I this post would take too long to read. So, I will close off by reiterating that I am excited to learn more from this course.

CST 300 - Module 4

Part 1 - Educational Goals This week's lecture readings in class have to do with setting goals. There are a few different types of goals to consider such as career, financial, family, artistic, attitude, physical, and public service. However, for now let's go over my educational goals. Some things I would particularly like to learn more about are software design and software engineering. I want to be able to create more professional applications to be an important member of any team I may join in the work field. To be more general, I would like to pass all of my classes with a grade higher than a C as I think they all are useful to know, especially for some of the things I want to do in the far future. Part 2 - Career Goals Another type of goal I should talk about is my career goal. Overall, I would like to have enough experience in working with the game development industry. There are a few levels to this goal, one is I would like to work with a company that develops games suc

Part 1 - Review and Reflect Learning Strategy After reading a paper on effective study skills by Dr. Bob Kizlik, I have come to realize there are more aspects of studying than I realized, and I do follow a large amount of them. However, there are also some aspects in which I struggle with that I have noticed, especially recently when it comes to reading. Although, to save your time, I will talk about the top 3 aspects I believe I am good at, and the top 3 I am bad at. One thing I am good at is taking notes. Especially in the digital age we are in, there are many ways to take notes, for me I separate my notes by module and assignment using google docs. Another is getting the main idea in a reading, also allowing me to take notes to reflect on later, instead of re-reading an entire segment of an essay or book. Finally, I feel I am also adept at surveying, to get an idea of what I'm going to study, before I actually study. However, some things I need to work on is to actually read bec

CST 300 - Module 3

Hello Everyone, Part 1 Last week I mentioned the areas in studying I need to work on such as paying attention to what I am reading, and to stick to a schedule as I often lose focus and prolong assignments. So, after visiting AcademicTips.org, I took some notes on concentration. Some things I am trying to do differently is to further avoid any distractions and to keep focus on my studies by taking breaks less often but do something that needs to be done other than just daydreaming, such as using the time to eat. Part 2 This week’s class module covered quite a bit of material. The readings covered topics such as the Code of Integrity for CSUMB CS Online, going over the rules of what should and should not be done when submitting any work or assisting/receiving assistance. Code of Ethics, as one may expect, be honest, avoid harm, maintain high standards, be professional, and many more aspects of what it is to be ethical in one’s work. This module puts an emphasis on ethics as it is the ma
