CST334: Journal Entry Week 7

 This week I learned about operating system persistence. This mainly covered how content is written or copied to different registers in a computer. An example of this is accessing hard disk drives. Disks have an architecture that composed of multiple tracks that store data. This requires efficient scheduling mechanisms to access sectors on the track. Some scheduling mechanisms include short seek time first, which orders the I/O in a queue and picks request on the nearest track to complete first. Errors in bit storage can be managed via Redundant Array of Inexpensive Disks.

CST438 Week 6 Journal

This week i learned about Service-Oriented Architecture (SOA) and its significant impact on modern software development. I learned that SOA promotes the creation of independent services that can communicate over a network, enhancing interoperability and system flexibility.

However, I also recognized the challenges associated with SOA, such as increased complexity and the need for effective data management and governance. Overall, understanding SOA has given me valuable insights into designing systems that can adapt to changing business needs while optimizing resource utilization.
