Following the previous System Programming-Basics, I moved into socket programming, and the lecture made clear what had felt abstract before - concepts like "Socket = File" and "when you go TCP, it becomes TCP Socket." I couldn't understand what these meant before. Also, the 3-way handshake process and the use of listen, bind, accept functions that I couldn't grasp when just looking at theory - experiencing how coding follows the exact same sequence as shown in diagrams made me feel like I could become friends(?) with socket programming diagrams. It seems like this was a meaningful lecture in that regard. ===== By this week, I'll complete a full review of the socket programming lectures / restudy the address book linked list, and then move into network programming. Since there's a lot of overlap with my previous studies in OS, TCP/IP, and system programming, understanding hasn't been too difficult, so progress is going faster than expected, making me wonder "Is this right?" 😆😆
