This week we covered some additional information in regards to the data layer‚ more specifically the MAC layer‚ and went into the network layer of the OSI model. As part of that we discussed different routing protocols and systems. Describe any feedback you received or any specific interactions you had. Discuss how they were helpful. Describe your feelings and attitudes. What surprised me or caused me to wonder? The feedback on my week 2 assignment was good. While it identified that there were

Exercise 4.1. Why are standards so important for NICs‚ connectors‚ and media? The NIC works at the physical and Data Link Layer only and does not use TCP or IP those are programs that are on your computer. Standards are put in place to make everything work good and ease. They are also developed to allow teaching. Without having standards there is chaos‚ in the computer world chaos means everyone goes back to using typewriters and mailing things through the post office. Exercise 4.1.2 The voltage

Analysis and Countermeasures of Network Security LiuBingyao Abstract This article is concerned about network security. It mentions about the present situation of network security and an analysis of the reason that lead to unsafe network environment. Then the article introduces two frequently used protocols in network security: HTTP (Hypertext Transport Protocol) and HTTPS (Hypertext Transfer Protocol over Secure Socket Layer)‚ then compare them and give a brief conclusion.
