TMA 02 Tutor-marked assignment TMA 02 Assignment submission This module requires all assignments to be submitted electronically. To submit an assignment, please follow the link(s) from your StudentHome page to the online TMA/EMA service. If you foresee any difficulty with submitting your assignment on time, you should contact your tutor well in advance of the cut-off date. Help with assignment questions You should read the TM112 Assessment guide in the Assessment section of the TM112 website before answering the questions here. If you need further guidance on any assignment questions, please ask your tutor, who will be happy to help. Do not discuss TMA questions on the forums. Your TMA answers must be your own work. The University takes copying answers from others, collusion with other students and soliciting answers from others very seriously. Assignments are checked both automatically and by your tutor. Any offences can have grave consequences, from disallowing part or whole of an assessed piece of work to withholding or withdrawing qualification, credit or registration. https://learn2.open.ac.uk/mod/oucontent/view.php?id=2263345&printable=1 07/06/2024, 11:16 Page 1 of 17 Word count You must provide a word count for each question or question part where a limit is specified. Evidence of Block 2 quiz engagement for this TMA 02 The final question of this TMA asks you for evidence of engagement with the Block 2 quiz. Read the final question first to make sure you know what will be required. Question 1 (23 marks) You must give a word count for any question with a maximum word limit. This question is about Block 2 Part 1. In Question 1, Question 3 and Question 6 of this TMA you will explore the roles of cloud computing, smart devices and location-based services in a smart parking system. Before answering these three TMA questions, you will need to read the article that can be found here: https://www.mokosmart.com/smart-parking-system-using-iot/. Your answers will be based on the content of the article and the module materials. Note that if (and only if) this external link becomes inaccessible, a pdf copy will be made available to download from the Assessment page. Each of Questions 1, 3 and 6 can be answered independently of each other, but you may find it useful to read all three questions before you start so as to avoid any duplication in your answers. a. Define what is meant by the Internet of Things (IoT). Then continue by relating each part of your definition to the context given in the article, being clear as to what the 'things' are, the kind of data being processed in the cloud and the technologies being used to connect them together within a bigger system. The maximum word limit for part a. is 125 words. (8 marks) https://learn2.open.ac.uk/mod/oucontent/view.php?id=2263345&printable=1 07/06/2024, 11:16 Page 2 of 17 b. Do you think that smart parking is 'green'? Give at least one point on either side of the argument and come to a clear conclusion. The maximum word limit for part b. is 120 words. (8 marks) c. Cloud providers say that the cloud offers elasticity and scalability in terms of its processing capabilities. Explain what the terms in italics mean and suggest how the owner of a smart parking scheme might benefit from each. The maximum word limit for part c. is 70 words. (4 marks) d. Write a reference for this article using the Cite Them Right version of Harvard guidance here: Cite Them Right It is important that you follow the format carefully as you will be assessed on your accuracy in following a referencing guide. (3 marks) (Total 23 marks) Question 2 (18 marks) This question provides an opportunity for you to demonstrate your understanding of the problem- solving approach taught in TM112 and the patterns introduced in Block 1 Part 4 and Block 2 Part 2. You can find an overview of the problem-solving approach and a list of all the patterns TM112 teaches in the Problem solving and Python quick reference and you will need to refer to this document as you work on the question. Important note: you do not need to get a working program in part a. in order to attempt part b. A student wants to write a program to check whether a book ISBN number is valid or not. Here is a top-level decomposition: https://learn2.open.ac.uk/mod/oucontent/view.php?id=2263345&printable=1 07/06/2024, 11:16 Page 3 of 17 > Check ISBN number >> Initialise a list to the 13 digits of the ISBN number to be checked >> Make a new list by leaving the items at the even indexes (0, 2, 4 etc.) unchanged and multiplying the items at the odd indexes by 3 >> Find the sum of the items in the transformed list >> If the remainder of the sum divided by 10 is 0, result is valid, else the result is invalid >> Print the result So, for example, if an ISBN number is 978-0-141-18321-3 the input is this list: [9, 7, 8, 0, 1, 4, 1, 1, 8, 3, 2, 1, 3] and the output will be valid. One of the tests of your code should be for an input list representing a possible ISBN number partly based on the example given above and partly derived from your Pl number. So, the first six digits in your ISBN list should be the first six digits from your PI number and the remaining digits will be 1, 1, 8, 3, 2, 1, 3. So, for example, for the Pl number B9081720, your ISBN list will be: [9, 0, 8, 1, 7, 2, 1, 1, 8, 3, 2, 1, 3] The first part of this question will only consider the following part of the decomposition. >Check ISBN number >> Initialise a list to the 13 digits of the ISBN number to be checked >> Make a new list by leaving the items at the even indexes (including 0) unchanged and multiplying the items at the odd indexes by 3 You may want to temporarily add a print statement to check the output. https://learn2.open.ac.uk/mod/oucontent/view.php?id=2263345&printable=1 07/06/2024, 11:16 Page 4 of 17 a. i. Describe the input data and the output data for this first task. ii. Specify one further input list you might use in testing in addition to the list you have created using your PI number. Make sure that you state the test input, the expected output and a brief explanation of why you selected this test. iii. Write an algorithm based on Pattern 2.4. iv. Implement your algorithm as Python code. Your code must match the steps of your algorithm and you should use comments in the code to make it clear how the two correspond. Marks will be lost if the program does not follow the algorithm. Copy your Python code, as text, into your Solution document. Name your Python file Q2a_OUCU.py, where ‘OUCU' is your OU computer username, e.g. abc123. Then include the code file in your TMA zip file. You should aim to use only the Python features that are introduced in the module. If you decide to use techniques or language features that TM112 does not cover, you must give a justification for your decisions; otherwise, marks will be lost. (9 marks) b. In this part of the question, you will implement the final steps in the top-level decomposition given at the beginning of this question: >> Find the sum of the items in the transformed list >> If the remainder of the sum divided by 10 is 0, result is valid, else result is invalid >> Print the result So, for example, for this step, if the input is the list: [9, 21, 8, 0, 1, 12, 1, 3, 8, 9, 2, 3, 3] The output valid will be printed. https://learn2.open.ac.uk/mod/oucontent/view.php?id=2263345&printable=1 07/06/2024, 11:16 Page 5 of 17
