In my fourth semester, I delved into a variety of subjects that further broadened my technical knowledge and skills. I engaged with 'Data Structure Applications', where I explored various data structures and their practical uses in software development, enhancing my problem-solving capabilities in computer science. Additionally, in 'Arm Processor and', I continued to deepen my understanding of ARM processors, focusing on their architecture, programming, and applications in embedded systems, which was crucial for my development as an embedded systems engineer. Lastly, in 'LIC', I studied Linear Integrated Circuits, gaining insights into the design and analysis of analog circuits, which complemented my previous work in analog electronics by providing a more advanced perspective on circuit integration and signal processing. These courses collectively provided a comprehensive learning experience, bridging the gap between software, hardware, and integrated circuit design.
