+## TIL
+
+### CS
+
+Python Programming: In my Python Programming course, I delved into file handling. Since basic operations like read() and write() are relatively straightforward in Python, I focused primarily on the underlying computer science principles related to file systems. Furthermore, I took the opportunity to review the von Neumann architecture, a fundamental concept that had temporarily slipped my mind.

+
+Database Systems: Regarding Database Systems, my study centered on hashing and specialized indices. Initially, I assumed hashing would be a manageable topic. However, comprehending the theoretical aspects involving buckets and bits proved to be far more challenging than anticipated. This also reminded me that implementing hash functions was the most demanding part of studying algorithms.
