ICT Services and Management Assignment -
Assignment 1 - 10 tasks and it should be 250 to 300 words each.
1. The text discusses how modern CPUs function. Recently a critical flaw in microprocessor design has been discovered that allows two extremely serious security exploits: Spectre and Meltdown. Find and summarise ONE resource that describes how either of these exploits work. The resource (and your summary) should focus on what is occurring in the CPU that allows these exploits to occur.
2. Prior to 1985, there were very few Operating Systems (OSes) that used Graphical User Interfaces (GUIs). Find and summarise ONE resource that describes ONE of these GUI operating systems. The OS must have been release prior to 1985 so cannot be Microsoft Windows.
3. Low-Powered Wide-Area Networks (LPWANs) are wireless communication networks that are characterised by linking devices over large distances. Devices (including simple sensors) typically can only communicate at very low bit rates, however, the communication and associated electronics consume very little power. As such, LPWAN devices can be battery powered and operate independently for many months or even years. Find and summarise ONE resource that describes ONE platform or technology that implements a LPWAN.
4. Voice over IP (VoIP) is a group of hardware and software technologies that allow users to communicate via voice and video over the Internet. VoIP uses a number of different software protocols, depending on the application. Find and summarise ONE resource that describes ONE of these VoIP protocols.
5. One of the many uses of cryptography has been the development of the blockchain. Blockchains are commonly used as the basis for maintaining the data integrity of crypto currencies, though have many, many more applications. Find and summarise ONE resource that describes how blockchains work. Note that the resource should focus on the blockchain mechanism, NOT crypto currencies.
6. One controversial practical application of network traffic management is in the contravention of the principle of "net neutrality". Find and summarise ONE resource that describes what net neutrality is and how its contravention could impact on individual and business users of the Internet.
7. Information Systems have led to greater and greater degrees of automation in the workplace. There is currently extensive speculation on which jobs will cease to be performed by humans in the near future. Find and summarise ONE resource that discusses jobs that are likely to not exist in the future due to ICT based automation. Note that the resource must clearly link the loss of the job(s) to advances in ICT.
8. With the advent of mass data collection and storage has come the use of these datasets for machine learning. Find and summarise ONE resource that describes what machine learning is and how it is being used.
9. Critical to application development are the languages used to implement the specifications. Find and summarise ONE resource that describes ONE programming language that has been developed since 2008. The resource (and your summary) should include information on the principle uses and features of the language.
10. While information systems and technology deliver many benefits to society, they can also result in negative effects and outcomes. One recent controversy, the propagation of fake news and its influence on elections, has been linked to a type of software called a "bot". Find and summarise ONE resource that describes what bots are and how they can be used for disseminating misinformation and affecting human behaviour.
Assignment 2 -
Introduction - In this assignment, you are to implement a console application that supports simple BMI (Body Mass Index) analysis functionality through a class called BMIAnalyser. A phased implementation approach is recommended; refer to Appendix 2 for further details.
The Application - The data to be analysed is to be loaded from 3 arrays containing person identifiers, heights (in metres) and weight (in kgs) using the loadFromTables() method provided in Appendix 1. Loading involves the creation of objects of type Record from each data triple (id[i], height[i], weight[i]). These are to be stored in an array of type Record called data. The size of this array is to be the same size as the data arrays. During loading, the BMI for each individual is calculated, using the following formula:
BMI = weight / (height*height)
where weight is in kilograms and height is in metres. The corresponding category is then determined as follows:

This allocation is to be provided as a separate (private) method called classify() that is not provided in Appendix 1. The code for loading is provided in Appendix 1 as the method loadFromTables(). In order to facilitate search, data is to be maintained in ascending order of person id. Sorting is to be done after loading, using a method called sortById(). This method must implement the insertion sort algorithm. Note that loadFromTables() and sortById() are to be invoked from the constructor for the BMIAnalyser class.
The application's View class is to execute (using a switch statement) the following command options:
1. Display the record for a specified person
2. Display records for all persons with BMI values within a specified range.
3. Display the minimum, maximum and average BMIs
4. Exit the application
Note that
1. Each command is designated a number
2. Command 1 requires a single argument - the subject id
3. Command 2 requires 2 arguments - the lower and upper bounds of a range of BMI values
4. I have added a "help" command (command 0)
5. The command options are displayed at the start of the application and whenever a "help" command is entered, rather than than after each command.
6. Records are displayed with no explanation of the fields
Feel free to adopt the above scheme or if you prefer, implement a more verbose interaction scheme.
