Before class, I had no idea what information systems would be about or what topics we would be learning. During, I definitely felt overwhelmed with the idea of having to prepare two or three technology news reports for each class, and then on top of that, being randomly picked to present our findings in front of the entire class. I will honestly admit that I do get nervous in front of certain crowds of people, especially if it is a larger group. Although I'm feeling stressed about this course and the requirements already, I really hope that everything just falls into place and that I'll finally get comfortable participating more.
When we started the lecture, I found myself really interested in how you were explaining how emails are sent through packets. I never knew that these packets travel different routes to get to the same destination. I always thought they all travelled together just like it shows you when you send your email and up pops a virtual envelope magically flying and disappearing into cyberspace. I also never knew that the Internet is considered hardware, and different than the world wide web, which it being software.
I did want to clarify if DNS (domain name server) is just the IP address for something?
Also I was confused about the meanings for DOS and CLI...

ReplyDeleteOK, let's see here....DOS stands for Disk Operating System, an outmoded system practically never used anymore. CLI stands for Command Line Interface, a system primarily used by hard-core computer types. I will demo the CLI system later this semester, and you will quickly see why normal people don't use it.
Next, the DNS system is a way for people to get around the World Wide Web using language (e.g., www.facebook.com) instead of using the IP address for websites (facebook's IPv4 address is in fact 69.63.181.37)
Don't panic about the oral presentations; everybody will have to do them and they're fun (at least when other people do them!)
