Week 12: Clear

Week 12 touched base with the basics about communication & networks. This weeks topic was an extremely informational and I thought it was a great benefit to learn. Until now I had no idea that there were so many types of networks. The four types of networks are LAN (Local Area Network), WAN (Wide Area Network), MAN (Metropolitan Area Network) and PAN (Personal Area Network). Each one of these networks are utilized in their own unique way according to what a business or person needs. Networking can facilitate communitcations, increase productivity, share software, be more effecient, you can share data and information and even transfer funds. The main fallback to networking is the security threat and lack of privacy. Also, on some occassions there may not be enough site licenses on software for every member to use.

Bandwidth was a term I was very familiar with when watching the lectures. In bandwidths relation to latency, you want a high bandwidth and a low latency. You want to have a great connection to be able to transfer a lot of data in a short amount of time without any lag.

One of the hardest things for me to catch on to was the TCI/IP (Transmission Control Protocol/Internet Protocol). This is broken down into two layers, TCI which is responsible for verifying the correct delivery of data from client to server and IP  which is responsible for moving packet of data from node to node.

The following link allowed me to better understand the complete development of the TCI/IP system.

I learned the reliable and unreliable modes and the specific uses of the IP.
