+Discrete Mathematics  ICT101 Assessment 3 ( 50%) 
+Instructions  
+Assessment Type :  Individual Assignment  
+Purpose of the assessment : To develop a plan for a real -world example of an 
+application in information technology from the one of the topics given below . 
+This assessment contributes to the various learning outcomes of your Bachelor 
+of IT degree.  
+ 
+Assessment Task : In the initial part of assignment, the student  will be tested on their skills on 
+writing literature review of a topic student  have learnt in the Discrete Mathematics (ICT101) course 
+in the week 1 to 6. Students need to read at least 3 articles or bo oks on this topic especially with 
+application to Information Technology  and give detail review of those. Student will also identify one 
+application of information Technology related to the topic in which he/she is interested and write a 
+complete account of  that interest.  
+ 
+Student  can use the following database to find article or books.  
+             o EBSCO Databases  
+             o Emerald Insight  
+             o IBISWorld  
+             o IGI Global  
+             o ProQuest eBooks  
+             o O’Reilly Learnin g  
+ 
+Student will  be exploring and analysis the application  of information technology related to the topic  
+which are identified by him/her , and he/she  must  recognise an application that can be programmed 
+into computer. Each group must sketch a plane to draw a flow -chart and algorithm. Use some inputs 
+to test the algorithm (Give different trace table for each input) and identify any problem in the 
+algorithm. Suggest a plane to rectify or explain why it can ’t be rectified. Each student  must write on e 
+report on its findings.

+Student  can choose one from the following Topic. However, after deciding on the topic to work on , 
+consult with your tutor.  
+The topic  student  group can choose from are : 
+• Number system used in Computing  
+• Logic in computing  
+• Inverse Function in Computing  
+• Induction Proof and its computing applicatio n 
+• 16-bit representation  
+• Cryptography

+1. Introduction  
+2. Proper reference of at least three articles or books  
+3. Write detail review of those articles or books related to the topic student chooses

+4. Identify one application in Information Technology in which student is interested.  
+Write a complete account of that interest  
+5. Description of why students choose this application  
+6. Give a complete plane to implement the application into a computer program with use of 
+flow -chart  
+7. Write an appropriate algorithm  
+8. Use at least two inputs to test the algor ithm. Group need to give a trace table for each input.  
+9. Conclusion  
+10. Short statement about contributions/Reflections from each group member  
+11. References  
+ 
+ 
+ 
+Deadline to submit written report: On or before Sunday  18th May  2024, 11.59pm via Moodle.

+Discrete Mathematics  ICT101 Assessment 3 ( 50%) 
+Instructions  
+Assessment Type :  Individual Assignment  
+Purpose of the assessment : To develop a plan for a real -world example of an 
+application in information technology from the one of the topics given below . 
+This assessment contributes to the various learning outcomes of your Bachelor 
+of IT degree.  
+ 
+Assessment Task : In the initial part of assignment, the student  will be tested on their skills on 
+writing literature review of a topic student  have learnt in the Discrete Mathematics (ICT101) course 
+in the week 1 to 6. Students need to read at least 3 articles or bo oks on this topic especially with 
+application to Information Technology  and give detail review of those. Student will also identify one 
+application of information Technology related to the topic in which he/she is interested and write a 
+complete account of  that interest.  
+ 
+Student  can use the following database to find article or books.  
+             o EBSCO Databases  
+             o Emerald Insight  
+             o IBISWorld  
+             o IGI Global  
+             o ProQuest eBooks  
+             o O’Reilly Learnin g  
+ 
+Student will  be exploring and analysis the application  of information technology related to the topic  
+which are identified by him/her , and he/she  must  recognise an application that can be programmed 
+into computer. Each group must sketch a plane to draw a flow -chart and algorithm. Use some inputs 
+to test the algorithm (Give different trace table for each input) and identify any problem in the 
+algorithm. Suggest a plane to rectify or explain why it can ’t be rectified. Each student  must write on e 
+report on its findings.

+ 
+ 
+Student  can choose one from the following Topic. However, after deciding on the topic to work on , 
+consult with your tutor.  
+The topic  student  group can choose from are : 
+• Number system used in Computing  
+• Logic in computing  
+• Inverse Function in Computing  
+• Induction Proof and its computing applicatio n 
+• 16-bit representation  
+• Cryptography       
+ 
+The written report must have the following sections:  
+1. Introduction  
+2. Proper reference of at least three articles or books  
+3. Write detail review of those articles or books related to the topic student chooses  
+ 
+4. Identify one application in Information Technology in which student is interested.  
+Write a complete account of that interest  
+5. Description of why students choose this application  
+6. Give a complete plane to implement the application into a computer program with use of 
+flow -chart  
+7. Write an appropriate algorithm  
+8. Use at least two inputs to test the algor ithm. Group need to give a trace table for each input.  
+9. Conclusion  
+10. Short statement about contributions/Reflections from each group member  
+11. References  
+ 
+ 
+ 
+Deadline to submit written report: On or before Sunday  18th May  2024, 11.59pm via Moodle.

+Instructions  
+Assessment Type :  Individual Assignment  
+Purpose of the assessment : To develop a plan for a real -world example of an 
+application in information technology from the one of the topics given below . 
+This assessment contributes to the various learning outcomes of your Bachelor 
+of IT degree.  
+ 
+Assessment Task : In the initial part of assignment, the student  will be tested on their skills on 
+writing literature review of a topic student  have learnt in the Discrete Mathematics (ICT101) course 
+in the week 1 to 6. Students need to read at least 3 articles or bo oks on this topic especially with 
+application to Information Technology  and give detail review of those. Student will also identify one 
+application of information Technology related to the topic in which he/she is interested and write a 
+complete account of  that interest.  
+ 
+Student  can use the following database to find article or books.  
+             o EBSCO Databases  
+             o Emerald Insight  
+             o IBISWorld

+             o ProQuest eBooks  
+             o O’Reilly Learnin g  
+ 
+Student will  be exploring and analysis the application  of information technology related to the topic  
+which are identified by him/her , and he/she  must  recognise an application that can be programmed 
+into computer. Each group must sketch a plane to draw a flow -chart and algorithm. Use some inputs 
+to test the algorithm (Give different trace table for each input) and identify any problem in the 
+algorithm. Suggest a plane to rectify or explain why it can ’t be rectified. Each student  must write on e 
+report on its findings.
