Week 28 - Exploring Virtual Memory and FIFO

-

 This week I reviewed virtual memory and its role in modern operating systems. Virtual memory is a powerful concept that allows processes to have more memory than is physically available. It enhances system efficiency and simplifies the programming process. I touched on concepts like paging, where both logical and physical memory are divided into fixed-sized blocks. Logical pages are mapped to physical frames through a structure called a page table.

In this week’s lab, we covered the First-In-First-Out (FIFO) page replacement algorithm, which seems to be a crucial concept in operating systems. The goal of this lab was to simulate how FIFO works to manage memory efficiently and effectively on a system with limited resources. I was able to measure page faults and analyze how cache size affects performance. Understanding concepts like this are crucial for designing software that performs better under constrained conditions.

The End of the Byte Trail

Time really does fly. This will be my final journal entry, and it marks the end of Gerek’s “byte trail” and undergraduate journey in Computer Science at CSUMB. Looking back, I can see how much I’ve grown both technically and professionally. I’m glad I was encouraged to keep a journal because now I’m able to look back on my past entries to reflect on my growth. Throughout the program, I’ve developed a strong foundation in core computer science concepts like algorithms, data structures, databases, operating systems, networking, and software engineering. I learned important concepts for being a competent software engineer like documentation, testing, and clean code habits. I plan to carry these forward into my career. As I close out my chapter at Cal State Monterey Bay, I’m excited about the opportunity to step into the tech workforce. It seems learning in this field never truly stops, and I expect my education to continue evolving throughout my career as technology advances. I’m partic...

Reflections on Algorithms

-
On this week’s exam, I felt confident with core topics like merge sort’s Θ(n log n), and dense graph adjacency matrices. I know I'm able to apply some foundational techniques under pressure. However, I also made some mistakes that came from missing small but important details like carefully identifying the basic operation or following traversal conventions. I need to take a step back and think about both the big picture strategy and the fine details of implementation. This week also marks the halfway point of Algorithms, and I feel like my thinking has grown. It's been both challenging and rewarding because it pushes me to break problems down logically instead of leaning on my intuition - which I often do. I need to strategize more on how I analyze loops, recurrences, and data structures. It also helps to find solutions using precise mathematical notation. Even when I get questions wrong, I view it as an opportunity to sharpen my reasoning and improve my problem solving.

Refining Documentation and Planning Final Deliverables

-
This week, our team met with our clients Tian & Shuhe to go over the remaining parts of the project as we move toward final submission. During the meeting, we discussed the two different types of tests that will be conducted: a user test performed by Shuhe and a deployment test conducted by Tian himself. This meeting helped us understand what each evaluation will focus on and what we need to prepare for. Tian also requested that we create documentation for the project, specifically a README with a developer-oriented quickstart guide. I contributed to planning the structure and content of that documentation and began outlining what developers will need to quickly understand and run our system. Next week, our main focus will be making the README file, including setting up clear quickstart instructions. I will help consolidate our existing notes, scripts, and architecture explanations into a clean and easy-to-follow document. At the same time, we will begin preparing material for the ...
