Exam Structure and Wireless Technologies Understanding

Overview of the Exam Structure

• Exam Sections
  • Part one: Approximately 50 points, multiple choice questions, 5 points on BPMN diagram corrections.
  • Part two: Focus on spreadsheet modeling using Excel (closed internet/computer).
• Duration: Total exam time is 2 hours and 45 minutes.
• Content Focus:
  • Based primarily on key concepts highlighted in lectures.
  • Macros are not included in the exam questions.

Exam Preparation Guidelines

• Reading Material: Focus on selected chapters provided in the syllabus, emphasizing data validation and key topics discussed in class.
• Review Sessions:
  • Attend review sessions on Wednesdays and Saturdays for clarification and guidance.
  • Review posted slide decks and take-home quizzes for practice.
• Key Topics to Study:
  • BPMN concepts (limited emphasis in part two).
  • RFM questions and advanced logical functions.
  • Key advanced topics covered in the course materials.

Exam Logistics

• Submission Process:
  • Part one must be completed and submitted before starting part two.
• Restrictions: So no laptops or internet during part one, but open during part two.

Wireless Technologies Discussion

• TCP/IP Basics:

  • Developed in the late 1960s to create a resilient communication network during the Cold War.
  • Allows data packets to be routed independently of any single path.
  • No memorization of terms like DNS, DHCP, etc., but understanding of how data packets traverse networks is crucial.

• Concept of Latency:

  • The time delay in data transmission affecting user experience, influenced by distance and congestion.
  • Applications like video conferencing are sensitive to latency; managing user experience by positioning resources closer to your user base is vital.

Analogies for Understanding Data Networks

• Road Networks as Data Networks:
  • Data packets are compared to automobiles traveling through road networks.
  • Bandwidth parallels the width of a highway; larger bandwidth allows for a greater flow of data.
• Traffic Congestion:
  • Just like cars can congest a highway, too many data packets can slow down internet speeds affecting user experience.

Key Networking Concepts Explained

• Data Packet Management with TCP/IP:

  • TCP breaks data into manageable packets that can be sent across the network, allowing efficient transport and routing.
  • Each packet is tagged to ensure it can be reassembled at the destination.

• UDP vs. TCP:

  • UDP allows for real-time communication without waiting for acknowledgments of reception, making it ideal for live streaming and gaming.

• Digital Divide:

  • The challenge of ensuring equitable access to high-speed internet across differing geographical regions, mirroring the historical building of transportation roads.

• Network Neutrality Debate:

  • Discusses the fairness of internet traffic management and how certain services may be prioritized or throttled based on external factors.

Conclusion and Important Reminders

• Final Exam Preparation: Emphasize understanding key concepts, practical exercises from lecture and class materials, and familiarize yourself with Excel for data modeling. Stay engaged in review sessions and bring questions to clarify uncertainties before the exam.
