This week in CST311 we focused on the Transport Layer of Computer Networks. This layer is critical for computer networks and provides the method for connecting computers through the internet. We learned about some of the principles for reliable data transfer and how to control and monitor data flow and congestion control. We also took a deeper look at UDP and TCP, two internet transport layer protocols. We learned how the protocols differed and in what situations you would use one or the other. The big programming assignment this week was a group project where we implemented two types of pinging programs a standard ping and heartbeat ping service. Completing this programming lab helped me further understand how computer networks communicate with each other.
This week we learned how to implement a different type of database using MongoDB. For our group project this week we changes the SQL code to MongoDB code. Both of these database applications do a fine job of working with data and saving it to a database. I did find that MongoDB seemed more streamlined than working with SQL. With SQL there seemed to be more setup as in creating prepared statements, and then executing queries. With MongoDB it seemed like a good chunk of the code was abstracted away and this made for cleaner looking code at the call site. If I had to choose I would likely go with MongoDB as it seemed more approachable.
