Learning Module Two Blog Post
This
learning module was a fairly long one. It encompassed many things and I really
felt like I learned a lot from it. From definitions, to activities, to
assignments, this module was filled with learning opportunities made for a
student to easily take advantage of. It’s easier to learn the material when
almost everything is online, can be easily accessible, and we work online to
learn about online. This class is almost like a workshop class. It’s hands on
and we work one-on-one with the tools we are learning about. This makes
learning easier and I feel that, under this method, most students retain more
of the information. I know I do. So, what have a learned? Well, it might be
hard to cover everything, because I really feel in this class that I am almost ALWAYS
learning something new, but I’ll try my best to cover some of the most
important topics and lessons I learned from this learning module.
In this
module, we learned how computers communicate with each other, send messages
over the internet, and understand files that we can access through the World
Wide Web. We learned about TCP/IP, which is a protocol used for transferring
data. FTP, another protocol, is used for file transfer. The modem is able to
convert analog signals to digital ones, and also digital signals to analog
ones. The server handles the data you request, and the bandwidth is the amount
of data that can travel from server to server and across the internet at one
time. All of these elements play a crucial role in internet and computer communications
and without them, computing between computers would be nearly impossible.
We also
learned about something most of us come across, but maybe don’t fully
understand. Cookies are little files that are stored in our computer for a
multitude of reasons. There are different types of cookies, and all of them do
similar and different things. For example, there are temporary/session cookies,
persistent cookies, first-party cookies, and third-party cookies. One thing I
never knew was that third-party cookies are usually unwanted by the user, while
first-party cookies are safe and okay to have in your computer. Third-party
cookies usually come from a website accessed through a different website. For
example, while on Amazon.com, you may receive cookies from other websites
selling through Amazon.com. They didn’t come from Amazon.com, but from a
third-party. These cookies may be more than data that saves settings and
personalizes searches and preferences. These cookies could be a number of
things including malware, spyware, or adware.
Malware,
spyware, and adware are all able to affect your computer’s performance,
sometimes without you even knowing it right away. Malware is software designed
to infiltrate your computer and cause harm to a multitude of software
components. Spyware installs itself on a computer secretly, often times
tracking computer use and obtaining data for demographical research. Adware is
less harmful, but will often times be frustrating, causing ads to appear on
your computer.
Your
computer can also be infected with viruses. We’ve all heard the term, ‘virus,’
when dealing with computers, but there are a few different kinds that are
important to be aware of. In class we focused on learning about worm viruses
and Trojan horses. Worm viruses can be pretty deadly because they can spread on
their own; they do not need a human to duplicate and infect other computers.
Trojan horses can be very tricky. They disguise themselves as something else,
such as a, seemingly safe, software download. Instead, you download a virus and
before you know it your computer is running slower, your settings aren’t what
you set them to be, your internet is acting up, and worst of all, your computer
crashes and you lose valuable information.
Thankfully,
viruses can be avoided and people have come up with some ways to stay one step
ahead of these internet threats. By installing some simple anti-virus software
and keeping your network’s firewall in working order is a great way to stop
viruses from infecting your computer. Anti-virus software ranges in price from
free to over a hundred dollars. When choosing the right anti-virus software, it
is important to think about what is best to fit your computing needs. If you
use only a laptop at home mainly for offline functions, you probably don’t need
a $100.00 anti-virus software.
To go
along with all of this virus-protection and internet safety, we played some
games in the learning module that helped reinforce the importance of computer
knowledge and staying sharp on how to be safe on the internet. All of the games
included tips on protecting your computer from viruses, phishing scams, cyber
criminals who try to steal credit card information and social security numbers,
wireless hackers, and spamming scams. These games were a really fun and
interactive way to learn more about the information covered in class. By
playing a game, I was able to retain more of the information because I am able
to remember the in-game scenarios and the choices I made to complete the game
successfully. I feel many people could learn a lot more this way than from
listening to a lecture every class.
We also
learned a lot about IP addresses and Domain Names. I have dealt with these
things before because I use wireless devices to go online, watch Netflix, and
play games. I encountered a problem with one of my devices about a week before
we started this module. The device couldn’t find the IP address to connect to
my at-home wireless internet. At first I was frustrated as this had never
happened before and I didn't know much about IP addresses. Luckily I was able
to find some information online and I had in fixed the next day. Even though I
fixed it, I didn't really understand what an IP address was or why it was
necessary. Intro to Web Technology cleared up any confusion I had. An IP address
is, “a number that uniquely identifies each computer or device connected to the
internet,” (Shelly, Cashman). Thinking back to the situation I ran into with my
device, I ended up having to reset the IP address because it was lost when my
wireless router was unplugged. I still don’t know everything about this, but
it’s nice to know what an IP address is when I have to fix it in the future.
We also
took a look at registering a Domain Name and the processes of obtaining your
very own website. We learned how to apply for a domain name, how long it would
take to get one, how much it would cost, and some good tips for choosing a
domain name that is right for you or your business. Many of us may have to set
up our own websites in the future so this information is very important to
know.
One of the best sections of this learning module was
creating a screencast. I've seen them before and I always wondered how to make
one. I had always assumed one needed some sort of hardware hooked up to a
computer that was capable of capturing screencasts. I had no idea that there
were many websites available that allow people to make screencasts for free.
For class we made a basic screen cast discussing features of the browser of our
choice. I choose Google Chrome, and just by doing the screencast I learned a
lot about Google Chrome that I hadn't known before. Below is a video of the
screen cast I made for class.
Finally,
I would like to add that I really like the online quizzes we have throughout
the learning modules. Having these small quizzes really makes it easier to
remember the information, because what we’re quizzed on is what we’re learning
about. We don’t learn about a multitude of topics then are tested on them all
at once at the end. Instead, we learn a few topics, take a quiz, then move on
to a few more topics and a few more quizzes, all while working hands-on with
the information we are learning about. This is a great way to learn and I’d
like to see more of this in other classes.
I
should also add that in two years of college, I have never used a book as much
as I have in this class. It seems contradictory that a class conducted mainly
online would find so much use with the book, but the fact that a lot of the
material is online, I find it even more helpful to use the online and on-hand
book source in unison to get the most out of the class.
