7.4 Using flowcharts to describe a task (contd)

Now consider what happens when you are weighing, for example, flour on a set of scales. You slowly add more flour to the scalepan until you reach the desired weight. As you do this the display constantly changes, showing the weight increasing as you add more flour. To do this, the scales’ computer must repeatedly examine the input and update the display each time it does so. The flowcharts in figures Author(s): The Open University

Introduction

This course introduces the important distinction between our analogue world of colour, sound, taste and touch and the computer's peculiar binary world of digital entities. Concepts of the analogue universe in which we live and the digital world we create are explained. The way in which information, in the form of text, still and moving images, and sound can cross the boundary from the analogue universe into a digital world is explored.

This OpenLearn course provides a sample of Level 1

8.2 Broadening perception

Particular perspectives and points of view underpin speaking and writing. Being successful at many academic tasks, including balanced argument, often requires us to be conscious of and to try to break away from our usual perspectives and ways of thinking, and to attend to things we might not normally notice. The challenge is often to be more open-minded and broad in our thinking, to consider more than one point of view in the way that the caffeine article did. It can be useful to have strateg

Managing Creativity and Creative Management
As the Creative Industries become a more important part of the global economy does the stereotype of the creative genius still persist? Do we need to rethink our ideas on creativity and understand how it works more clearly?

5.4 Indris and sifakas

Both indris and sifakas are unusual amongst lemurs in that they are active largely by day. Leaves are their primary food. They have a specialised form of locomotion, best described as 'vertical clinging and leaping' and the leaps they can take, using their powerful legs, can be up to 10 m. DA describes the bounding movement of sifakas when they are compelled to come to ground. (If you go back to the previous video sequence that shows this strikingly white species - the so-called silky sifaka

Discussion of media buying and the attention-creation industry - showing how the fixation on audiences' click-like behaviour is a disruptive institutional force, and how buyers' new approaches to attention are creating new forms of social discrimination.
