Week 3: Clear

This week we talked about networks and all that it includes. Part of the discussion was focused on TCP and UDP encapsulation. I found it very clear to remember and learn.

Networks use this encapsulation when sending data from one place to the next.
TCP stands for transmission control protocol and UDP stands for user datagram protocol. The difference when using these two types of protocol is how much data is guaranteed to be transferred to the destination requested. TCP guarantees your data will arrive safely and in its original full form. UDP only sends what happens to make it to the destination.

TCP guarantees the data will get there by going through one extra step; It's called retransmission. Although retransmission can sometimes slow the process down sometimes a company or PC user will use this for important data like bank records.
UDP does not guarantee the sender the data will arrive fully intact but it does guarantee that it will send it faster. Mr. Nelson said this would be okay to use when sending data like video or music because if anything is missing it wont be noticeable.

So what does retransmission mean? TCP retransmission requires that the receiver notify the sender that all parts were completely received and saved properly. According to msdn.microsoft.com, if the sender does not receive this notification of the packet the retransmission process will start again. 
Depending on the data and the time limit a receiver may have, chose your packet protocol wisely. TCP may send the data in complete form it does take longer; UDP sends the data faster but may be missing a few things.

Week 1: Clear

So week one-
The thing that was muddy to me was copyright but now it's clear to me what copyright is. I had never thought about the pictures on the web might belong to a copyright. The Disney you tube video was awesome!Copyright is placed on someone's idea or creation. Anyone, besides the holder of the copyright, who tries to use this material may face big consequences. As students, we must attribute all we use so that we are not penalized for stealing work. The following websites has the copyright law in full: http://www.copyright.gov/title17/
