FIT1047 Introduction to Computer Systems Networks and Security – S2 2025 Assignment 1

Assignment 1 – Numbers, Encodings and Boolean Logic

Task 

In this assignment, you will demonstrate your knowledge of number systems, character encodings and that you can construct and simplify Boolean formulas and circuits. The assignment relates to Unit Learning Outcomes 1 and 2.

Part 1: Submit your reflections

Part 2: Complete the individual tasks as detailed in the instructions below.

You need to submit a document that details your workings, as well as Logisim files for the resulting circuits.

Part 3: Complete the in-class test.

Criteria

Marks are awarded for the correctness of the calculations, the explanations of how the tasks were solved, and the documentation of test cases where required. The marking rubric in Moodle shows an individual marks breakdown. If no or insufficient reflections are submitted (Part 1), the overall marks for this assignment are capped at 30

Instructions

For Part 1, collect your reflections for Weeks 1 - 3 from each week’s Ed Lesson and create a single PDF document. You can simply copy/paste your reflections, but please add headings for each week. Please refer to the template as a reference of the structure of your reflections. While it is optional to follow the template, you are required to have your reflections specific to the topics covered in the corresponding weeks. The word count of reflection must be more than 100 words (excluding the headings provided in the template) in each week. Submit your PDF through the Moodle Assignment 1 Part 1 activity.

For Part 2, you need to submit two files through the Moodle Assignment 1 Part 2 activity: 1) A PDF document with the answers to the questions and your workings. 2) A separate .zip archive with the Logisim files (do NOT save as PDF file for your Logisim files) along with your individualised assignment specification.

For Part 3, is an in-class test during your allocated Applied session (for Australian cohort) / Workshop session (for Malaysian cohort) in Week 4. Instructions will be available separately.

Assessment Requirements Summary

The Assignment 1 – Numbers, Encodings and Boolean Logic is designed to test students’ understanding of number systems, character encodings, Boolean formulas, and digital circuits. It directly addresses Unit Learning Outcomes (ULO) 1 and 2.

The assessment consists of three parts:

1. Part 1 – Reflections (Weeks 1–3):

   • Students compile their weekly reflections into a single PDF.
   • Each reflection must be specific to the weekly topics, minimum 100 words each (excluding headings).
   • Reflections help demonstrate personal engagement with learning and link concepts to understanding.

   • If reflections are not submitted or insufficient, the overall marks are capped at 30.

2. Part 2 – Individual Tasks (Calculations + Logisim Circuits):

   • Students must solve problems related to number systems, character encodings, Boolean logic, and circuit design.
   • Deliverables include:
     • A PDF with detailed solutions and workings.

     • A .zip archive of Logisim circuit files.

3. Part 3 – In-class Test:

   • Conducted in Week 4 during the allocated Applied/Workshop session.
   • Focused on validating individual understanding of the concepts practiced.

Marking Criteria:

• Accuracy of calculations and circuit designs.
• Clarity in explanations and documentation of steps.
• Completeness and quality of reflections.
• Proper submission of files in required formats.

Academic Mentor’s Step-by-Step Guidance Approach

The academic mentor guided the student through the assessment in a structured manner, ensuring clarity and confidence at every stage:

Step 1 – Understanding Reflections (Part 1)

• The mentor first explained the importance of reflections in consolidating weekly learning.
• Students were guided to structure their reflections week-wise, highlighting what concepts they found challenging and how they overcame them.
• Mentor emphasized linking reflections with real-world applications of number systems, encoding, and Boolean logic.

Step 2 – Solving Individual Tasks (Part 2)

• Number Systems & Encodings: Mentor demonstrated how to approach conversions (binary, decimal, hexadecimal) with step-by-step worked examples.
• Boolean Logic & Simplification: Guidance was provided on using truth tables, Boolean algebra simplification, and Karnaugh maps.
• Circuit Design in Logisim: Mentor walked the student through designing and testing circuits. Each circuit was tested with inputs, and results were documented as screenshots or outputs to validate correctness.

Step 3 – Preparing Deliverables

• Mentor advised on compiling the PDF solution document with clear headings, problem statements, workings, and final answers.
• Explained how to save and organize Logisim files in a .zip folder for submission.
• Ensured that file-naming conventions matched instructions to avoid submission penalties.

Step 4 – In-class Test Preparation (Part 3)

• The mentor provided practice problems similar to likely test questions.
• Encouraged time management strategies for solving logic problems quickly.
• Emphasized revision of concepts from Weeks 1–3 as they directly linked to test content.

Final Outcome and Learning Achievements

Through this structured mentoring approach, the student was able to:

• Submit complete and well-structured reflections connecting weekly lessons to understanding.
• Develop strong problem-solving skills in number systems, encodings, and Boolean logic.
• Build and validate working circuits in Logisim that demonstrated theoretical knowledge in practice.
• Prepare confidently for the in-class test with a deeper grasp of foundational computing concepts.

Learning Objectives Covered:

• ULO1: Demonstrated knowledge of number systems, encodings, and Boolean logic through problem-solving.
• ULO2: Applied Boolean simplification techniques and designed functional circuits using Logisim.
• Developed reflective learning, technical documentation, and independent problem-solving skills.
