CST 334 Week 4

 This week I learned about paging and how it can help virtualize memory. Paging breaks process into pages or small sections of memory so they can be better stored within the physical memory of a system. This helps to address the problem of segmentation within physical memory as these pages can fit into smaller gaps than full processes. The process needs to think it has its own private address space in physical memory so paging sheets, which track where pages are in physical memory, are used so that a virtual address can be seen by the process to create the illusion of a contiguous memory space. 

    I also learned that it can be costly and consume a lot of time to translate a virtual address to a physical address due to having to transverse the page tables. The translation look aside buffer addresses this problem as common address locations are stored here to allow quick access for the OS to find. Paging is a great way to virtualize memory.

CST 370 Week 5

 This week we moved from learning how to read and understand algorithms, to a more direct approach to writing some of the more advanced algorithms that explore the more common mathematical and logical problems programmers tend to face. Learning about topological ordering, tree structuring, and quick sort was very interesting as these concepts are huge throughout the computer science landscape. COming off the test last week I feel reinvogorated to keep learning.

CST 370 Week 2

 This week was very interesting, I had learned about time efficiency and Big O, Theta and Omega notation in the past but it was great to learn formal definitions and see some examples of how they can be applied. Understanding how to evaluate recursive algorithms was new for me and pretty difficult to understand at first but after reading the text book and other required materials it started to make a little more sense. I would like to continue practicing evaluating both recursive and nonrecursive algorithms  just to continue understand the asymptotic notations a little bit more. Overall it was a good week and the homework was challenging in a great way.

CST 370 Week 4

 This week I was able to study some of the topics I struggled with in previous weeks like recurrence relationships. In preparing for the test being able to use two sheets of paper as notes was helpful for studying but also helpful for the test. A refresher on merge sort was also a welcome experience as well as the divide and conquer techniques.
