IB ITGS - 1. Introduction
What is ITGS?
- Information Technology in a Global Society is the study of how developments in IT affect people and society.
The ITGS triangle
- There are four core aspects of ITGS: * Social and ethical significance * IT systems * Application to specific scenarios * Stakeholders

Strand 1: Social and ethical significance
- Issues of social and ethical significance can arise whenever IT is used. These issues have social impacts on stakeholders.
- These issues are: * Reliability refers to how well a computer system works: if it functions as intended or fails and crashes. * Integrity refers to the correctness of data. * Security is concerned with protecting IT systems from unauthorized users. * Privacy is the ability to control how data about us is used. * A person becomes anonymous if they hide their identity and have total privacy. * Intellectual property refers to creations of the mind. * Copyright law is designed to protect intellectual property from unauthorized reproduction. * Authenticity involves a user proving their identity to gain access to a computer. * Digital divide and equality of access: IT has not developed at the same rate for everybody in all parts of the world. There are often individuals who lack access to technology. * Surveillance involves using IT to monitor people. * Globalization and cultural diversity: IT has helped to reduce global boundaries and speed up the global spread of news and culture. * Policies are rules designed to control the way people use IT, often in the form of laws. * Standards and protocols are technical rules that hardware and software designers should follow. * People and machines concerns the way that humans interact with IT. * Digital citizenship involves being a good citizen in a digital world.
Strand 2: Applications to specific areas
- Business and employment: many businesses make heavy use of IT to develop, advertise, and sell their products and services.
- Education and training: the availability of vast amounts of information for free on the Internet has opened up new educational possibilities for many people.
- Environment: robot vehicles and satellite technology have allowed us to explore and map Earth’s surface.
- Health: IT has helped advance healthcare in daily tasks. It also raises health concerns, such as addiction.
- Home and leisure: IT has changed the way we use our leisure time and the way that we interact with friends.
- Politics and government: governments have used IT to increase efficiency and transparency, as well as promote political campaigns.
Strand 3: IT Systems
- All IT systems take data as input and process it according to programmed instructions into output.
- A system will also store data and communicate with other systems via networks.
- They consist of: * Hardware: to input, process, and output data. * Software: to control the hardware. * People: to use the system. * Data: on which the system performs work.
