2.2 Memory

You should now be beginning to build up a picture of what a computer is: you know it needs input and output devices to communicate with the world outside and a processor to carry out the instructions that are programmed into it. But where are these instructions stored within the computer? The answer is that they are stored within what is called the computer's main memory, along with any data needed to carry them out.

However, the main memory in computers like PCs is much too smal

3 Lesson delivery

The way in which we deliver our lessons will have an impact on the students' interest and engagement in the work. If we appear enthused and excited by the subject that we are studying, then at least some of this enthusiasm will inevitably rub off on our class.

The successful teacher will deliver his or her lessons with a sense of:

  • Pace: keeping the class and the learning moving forwards.

  • Clarity: knowing where the les

You say you want: Revisiting Iran’s revolution

We examine how the echoes of Iran’s revolution, 40 years ago, still influence how the Islamic Republic deals with the West today. Harley Davidson has become entangled in the Trump administration’s trade war just as changing demographics have put the brakes on the motorcycle-maker. And, we tackle an old ethics conundrum and its relevance to future autonomous vehicles.

4.1 Introduction

We have seen in SAQ 18 of Section 3.4 how some sets of points of the complex plane can be described algebraically in terms of operations on C. We now use the modulus function to take this a step further by defining discs in the complex plane. As we shall see, discs are extensively used in arguments involving l
