2 Conclusion The versatile tiny transistor is now at the heart of the electronics industry. In the video clips you have seen the history of the incredible shrinking chip, its Scottish connections, and an explanation of the physics that make chips work as well as a reconstruction of making a transistor using the crude techniques of yesteryear.
2.2.3 Surfaces with boundary Examples of surfaces with boundary are a cylinder and a Möbius band. Other examples are the following:
Surfaces with holes
We can obtain a surface with boundary by taking any surface without boundary and punching some holes in it by removing open discs. For example, Figure 19 shows a sphere with 3 holes. The boun
2.2.2 Hollow tubing surfaces In their doughnut-shaped representation, toruses can be thought of as being hollow tubes. Many other surfaces in space can also be drawn as if they were made of hollow tubing. Figure 15 shows two such examples. 2.2.1 Surfaces without boundary Examples of surfaces without boundary are a sphere and a torus. Other examples are the following: n-fold toruses
Figure 13 depicts a 2-fold torus and a 3-fold torus, with two and three rings respectively. An n-fold torus, for any positive integer n has n rings. (A 1-fold torus is 3.3 What can genres do for you?

What are the relative advantages and disadvantages of connect 4.2 ATM layers In this section I shall briefly review some of the main functions of the ATM layers but I shall not go into too much detail because at this stage we are interested in only the general points about protocols. 3.4 Transmission control protocol (TCP) As I outlined in the previous section, peer entities in clients and servers exchange HTTP protocol data units when they wish to transfer a resource over the web. I gave very little detail about this because I wanted to focus on the general features of protocols in the application layer of the TCP/IP model. The HTTP protocol data units are transferred from the sender host to the receiver host by calling on the services of the transport layer. In the case we are considering, the transport layer 7.1 Introduction Earlier on I indicated that in order for a processor to perform a defined function it needs to be supplied with a list of instructions called a program. In this section I shall explore this idea a little further. Software can be split into two categories, application software and operating systems. Application software is the name given to programs which enable a computer to perform specific tasks. The program that processes the image in the digital camera is one example; a word Learning outcomes After studying this course, you should be able to: understand what all the terms highlighted in bold in the text mean understand the fundamental hardware components that make up a computer’s hardware and the role of each of these components understand the difference between an operating system and an application program, and what each is used for in a computer describe some examples of computers and state the effect that the use of References 4.2.5 Focusing Focusing is done by adjusting the size of the gap between the lens and the light sensor. To get distant objects in focus, the gap needs to be smaller than that required for close objects (see Figure 7 below). 4.2.4 CCD light sensor The CCD light sensor is a transducer that converts light to an electrical signal. CCD stands for 'charge coupled device', and physically a CCD light sensor is an integrated circuit with a transparent cover. A photograph of one is shown in Figure 6. Under the cover is a rectangular array of light-sensitive electronic components cal

Learn about trust in the organisational context. This free course, Developing high trust work relationships, introduces the concept of trust, what it means to you and how it may affect your organisation. First published on Mon, 12 Sep 2016 as Author(s):
This course looks at how to take investor objectives and constraints and turn them into a portfolio which aims at achieving an expected return and level of risk appropriate for the investor. In this free course, Asset allocation in investment, portfolio optimisation techniques such as portfolio theory can be used to determine how much of an investor’s portfolio to put in each asset class. Portfolio theory can also be used to determine so-called model portfolios which offer optimised benchmarks
This free course, Population ageing: a global health crisis?, focuses on two major issues of our time – ageing societies and global health. It provides you with an introduction to ageing societies and their implications for global health – implications which are only just beginning to be fully understood. The course will help you to deepen your understanding of ageing societies across the globe and the different components of the concept of global health. You will also explore the ways in wh
Digital evidence features in just about every part of our personal and business lives. Legal and business decisions hinge on having timely data about what people have actually done. This free course, Digital forensics, is an introduction to computer forensics and investigation, and provides a taster in understanding how to conduct investigations to correctly gather, analyse and present digital evidence to both business and legal audiences. It also outlines the tools to locate and analyse digital
