What is control?
Refugee tagging

Control is about purposeful influence towards a predetermined goal and can range from absolute control, such as a dictatorship, to more subtle influences such as the effect of television advertising.

Since the Industrial Revolution we have increased our understanding of the principles of control, which not only allows us to create more effective control systems but has also provided insight into the natural world and human affairs.

At the heart of control is the processing and distribution of information. This information could be a mechanical displacement, an electrical signal, or a letter from a disgruntled customer.

Computers make excellent control devices because they translate information from one form to another. Computers already control many aspects of our world, yet they are often hidden from view… We encounter hundreds of these unseen, tiny embedded chips throughout our lives in such machines as cash registers, traffic lights, calculators, personal computers, dishwashers, and other domestic appliances.

Increasingly, governments and corporations use computers to process and control information about people. Yet while information technology may seem to be the key to an efficient society, this use of computers also poses problems and many people are concerned about the potential for abuse. (Powerhouse Museum, 2001: 9)

Government and social organisations
Another worry that concerns many people is how we are governed. The way the country is run and the way society is structured depends on information. Governments and social organisations make decisions that affect our daily lives.

But what if the information they are basing those decisions on is wrong, or biased, or is not the whole story? If an incorrect piece of information gets passed from one system to many others, how would it ever be possible to fix the mistake everywhere? There was an example of this happening in the United States. A man was recorded as being dead when he wasn't, suddenly his pension stopped, he couldn't get medication because according to the system he didn't exist. It was a long complex process to convince the authorities that he was still alive, but a relatively simple process to fix the database and activate his life again.

Industrial revolution
In the late 1700s and early 1800s in Europe many new technologies were developed. Some of these technologies were invented to make things people needed, like clothes or teacups. Others were invented to improve transportation, like trains. Some were invented to help build other machines. This wave of inventions is associated with changes to the way people lived and worked. It even changed where most people lived (in towns instead of in the country). This period is called the Industrial Revolution.
