WGU D684 Exam 2025 | Introduction to Computer Science Course | Featuring Topics such as Programming Logic, Software Development Lifecycles, Algorithms, and Data Structures | Western Governors University

The WGU D684 Exam 2025 for the "Introduction to Computer Science" course at Western Governors University provides a comprehensive overview of essential computer science concepts, including programming logic, software development lifecycles, algorithms, and data structures. This exam is designed to assess students' understanding of key topics fundamental to computer science education.

The document delves into the role of memory management in operating systems, emphasizing the importance of efficiently allocating and managing system memory. It highlights process management tasks such as creating, executing, and terminating processes, which are pivotal in operating system functionality.

Another focal area is CPU scheduling, where the exam explores various strategies to optimize the order of process execution, thereby enhancing system performance. Disk scheduling algorithms are also covered, with a focus on minimizing seek time and maximizing throughput, using techniques like Shortest Seek Time First (SSTF) and SCAN.

In the realm of object-oriented programming (OOP), key principles such as encapsulation and abstraction are examined. Students learn about objects as instances of classes containing attributes and methods, and the significance of encapsulation in restricting access to certain parts of an object.

The exam also touches on the von Neumann architecture, particularly the control unit, and provides a description of a desktop PC, highlighting its use as a personal computing device with separate components.

This exam is a valuable resource for students looking to solidify their understanding of fundamental computer science concepts, making it an essential part of the curriculum for aspiring computer scientists.
