Answer:
IT in everyday life
Introduction
Whether we are aware of it or not, we are surrounded by networks through which information flows constantly. Our notions of time and location are changing – the world seems to have become a 'global village' where distance is no longer a barrier to commercial or social contact. If we live in Britain or other parts of the westernised world, it's difficult to imagine being without all the networked infrastructure that plays a crucial part in our daily lives. This free course, IT in everyday life, is about how this infrastructure of information and communication technologies permeates our lives.

1.1 Data and information
Although this course is about IT, the technologies you'll be learning about do not actually handle information. Instead they handle data. In everyday language the terms 'data' and 'information' are often used interchangeably, but it is important to understand the difference when you are studying IT.
Data is a representation of information so that it can be conveyed, manipulated or stored. Information is the meaning that people give to data in particular contexts. So data can't really be considered information until it is given meaning and is interpreted.
1.2 What is IT?
Before we go any further, it is useful to have a working understanding of the term 'IT'. What exactly do we mean by 'information technologies'? This can be very difficult to define and explain, but here is a simple definition.
Information technology (IT) is the technologies used in the conveying, manipulation and storage of data by electronic means.
Let us give you some examples. In a landline telephone system, messages are conveyed as signals on wires. The message is conveyed electronically. Manipulation of data takes place when you speak into the phone – your words are transformed into electronic signals. The data is then conveyed through the phone system, stored briefly for further processing on the way, and transformed back into words at the other end. In a mobile phone system, messages are also stored and manipulated but in this case they are conveyed by electromagnetic means such as radio waves, which are wireless.

Using the explanation of IT given above, would you say that the technologiy used for email communication is IT?
Reveal answer
Other examples of IT systems include the internet, mobile phone systems, broadcast radio and TV systems, but IT is essential to many other day-to-day activities. Consider for example a visit to a supermarket. Checkout staff use an IT system to scan bar codes and obtain prices. IT systems also allow management to monitor stock levels and sales trends.
1.3 Technology and society
IT systems are increasingly embedded in many aspects of our daily lives. But IT doesn't just exist in a vacuum – it has an impact on society, and society has an effect on it. It also has economic and political implications.
