CIS 145

Module 10 Summary

Module 10 was all about understanding data and how social media platforms handle it. The beginning focused on key data concepts, breaking down how raw data becomes information and then knowledge, depending on the context. I learned about metadata, which is essentially data that provides context for other data—like timestamps or locations, making the raw information more useful. The module also introduced different ways to organize data, such as stacks and queues, and emphasized how problem-solving in computer science involves techniques like abstraction and decomposition.

The most eye-opening part for me was learning about the data collection practices of social media platforms. Big sites like Facebook and Twitter collect a lot of information, from basic account details to your browsing history and even GPS data. The way they use and share this data stood out—whether it’s for personalizing your experience, targeted advertising, or even sharing it with third parties or law enforcement. However, the module also pointed out that users have some control, like adjusting privacy settings or opting out of targeted ads.
