Introduction In week 9's lesson, we looked at the topics of ethics and privacy. Here is some of the main concepts that stuck with me throughout this class. Ethics Ethics refer to the "principles of right and wrong that individuals use to make choice that guide their behaviour. There are four different approaches (or standards) towards ethics, this include: Utilitarian approach - Action that achieves the greatest good or causes the least harm.  Rights approach - An ethical action is one that best protects and respects the moral rights of the people involved. Fairness approach - An ethical action treats all persons equally, or if unequal, equitably, in accordance with some justifiable norm. Common good approach - An ethical action is one that benefits the entire community and is crucial for the well-being of all members, not just a few. Privacy Privacy is the right to be left alone without unreasonable personal intrusion. In class, we examined the rules and regulations that...

Introduction For week 8, we looked at and focused on Chapter 5; more specifically the topic of Business Intelligence (BI), and its main function in modern organisations. We looked further at BIs usefulness, and its potential to dramatically improve decision-making via data analysis. Some of the things that resonated that I learnt included BI's characteristics and functions, its importance, and its practical use in action.   Business Intelligence (BI) In today's technology environment, Business Intelligence (BI) is vital for modern businesses approach to data analysis and decision making. There is a great need for businesses to utilise BI tools to extract useful insights from massive amounts of data and their complex data systems. What might not seem obvious to humans (potential trends, etc), can be highlighted by BI; and with these fresh facts and analysis obtained, organisations may make more productive and efficient decisions with greater confidence. Essentially, BI has ultim...

Intro In this week's class, we explored the world of networks; more specifically what they (networks) are and how they have influenced business practices. Let's dive in: 4.1 What is a computer network? - A computer network enables data transmission by connecting devices via communication channels. - Networks have a need for more bandwidth in order to achieve faster functioning (measured in bits per second.) - Two different types of networks: local area networks (LAN) and wide area networks (WAN). - WANs connect numerous LANs, separating them from one another. 4.2 Network fundamentals In class, we discussed how networks transmit information using two sorts of signals: analogue and digital . Analogue signals:  Continuous waves that transmit information through amplitude and frequency changes. Digital signals:  Made consisting of discrete pulses that can be represented in binary as on (1) or off (0). Modems are critical instruments for transforming these signal kinds. ...
