CST 370 - Design and Analysis of Algorithms - Week 6

-

 



This week in CST-370, we learned about more advanced data structures such as AVL trees, heaps, and hashing. AVL trees solve the issue of unbalanced binary search trees by maintaining a balance factor between -1 and 1, ensuring logarithmic time complexity for operations like search, insert, and delete. I learned how rotations (left, right, and combinations of both) restore balance when inserting or deleting nodes. The concept of balancing height was interesting because it talks about the trade-offs between complexity and performance.

We also learned about heaps, focusing on their role as priority queues. A heap is a complete binary tree where each parent node adheres to a specific order property, either greater than (max-heap) or less than (min-heap) its children. I learned the importance of heapify operations and how heaps support efficient insertion and deletion in logarithmic time. Also, heapsort was introduced as a sorting algorithm that leverages the heap’s structure to achieve O(n log n) time complexity. Lastly, the discussion on hashing and collision resolution methods, such as linear probing and separate chaining, provided a clear understanding of how hash tables manage key-value mappings efficiently.

CST 334 - Operating Systems - Week 6

  This week in CST 334, we learned about the concept of semaphores, a fundamental synchronization primitive in operating systems. Semaphores manage access to shared resources using an integer value, which can be incremented or decremented by operations like `sem_post()` and `sem_wait()`. These operations allow semaphores to control resource access, ensuring that threads wait when the resource is unavailable and proceed when it becomes available. A key form of semaphore is the binary semaphore, which functions similarly to a lock by permitting only one thread access at a time, ensuring mutual exclusion.  In addition to basic semaphore usage, we explored various common concurrency problems that semaphores can help solve. For example, in the Producer-Consumer problem, semaphores signal the state of a buffer, preventing data corruption or loss. Similarly, the Reader-Writer problem uses semaphores to manage access, allowing multiple readers or a single writer to use the resource, b...

CST 363 - Introduction to Database - Week 3

  Explain in your words what 3rd normal form is and why it is important. Third normal form, also known as 3NF, is a crucial aspect of database normalization. The third normal form makes sure that the data stored in a relational database is organized to reduce redundancy and improve data integrity. In other words, 3NF is a database schema design approach for relational databases which uses normalizing principles to reduce the duplication of data, avoid data anomalies, ensure referential integrity, and simplify data management. Adhering to 3NF in database design is fundamental for building efficient and reliable database applications. It not only helps maintaining clean data structures but also supports accurate and efficient query responses.  What is an SQL view. How is it similar to a table? In what ways is it different? An SQL view is essentially a virtual table in a database that is not physically stored. Instead, it is defined by a query. A view can contain all rows of a ...

CST 311 - Intro to Computer Networks - Week 1

  This week in CST 311, I learned a lot about the concepts of computer networks, starting with an understanding of the internet's structure and operation. The internet is basically a network of networks, consisting of many connected devices, communication links, and packet switches, all working together with various protocols like TCP, IP, and HTTP. I also learned about the different components of a network, such as the network edge, which includes hosts like clients and servers, and the network core, where packet switching and routing occur. The significance of protocols is so important, as they define the format and order of messages sent and received in the network. Another topic was the concept of delay, loss, and throughput in networks. I learned about the different types of delays such as processing, queuing, transmission, and propagation which affect the overall performance of a network. The introduction to the internet protocol stack is also important, where I learned about...
