Networking with Packets
I find it truly baffling how digital data moves in the packets despite the fact that I understand the concept and idea behind it all. We have learned that the data in our computers uses the binary system. These 0s and 1s are translated into everything from mathematical equations to reports to pictures and videos. I understand the concept of this, however the actual process of breaking this all down into coherent data is a different story. From there, these binary bits are combined into packets that can be sent from computer to computer from one cubical to another and from one country to another.
The information on how all of this works is stated very clearly in our text: How Computers Work as it was also reiterated during lecture. The shear velocity of information that can be transported to and from millions of different computers through the use of MAC, for identifying the identity of the computer, IP address, for where it is going, TCP, for special handling, the UDP, or rush order, and the DNS, for translation from numbers to names seems to be too much information to be handled so thoroughly.
I found this website http://www.networksorcery.com/enp/protocol/ip.htm that offers more explanation as well as diagrams to help understand how the packets are put together as well as sent from one system to another. This second website, http://www.laneye.com/network/how-network-works/mac-address-and-ip-address-relationship.htm offers the same type of information with a much easier explanation on how it works. Both of the images that I used are under public domain under Google. The top image is from Laneye.com the second image is from forums.techguy.org.
