The aim of this book is to provide detailed coverage of the topics in the new OCR AS and A Level Computer Science specifications H046 / H446. The book is divided into twelve sections and within each section, each chapter covers material that can comfortably be taught in one or two lessons. Material that is applicable only to the second year of the full A Level is clearly marked. Sometimes this may include an entire chapter and at other times, just a small part of a chapter. Each chapter contains exercises and questions, some new and some from past examination questions. Answers to all these are available to teachers only in a free Teacher's Pack which can be ordered from our website www.pgonline.co.uk. This book has been written to cover the topics which will be examined in the written papers at both AS and A Level. Sections 10, 11 and 12 relate principally to problem solving skills, with programming techniques covered in sufficient depth to allow students to answer questions in Component 02. Pseudocode, rather than any specific programming language, is used in the algorithms given in the text. Sample Python programs which implement many of the algorithms are included in a folder with the Teacher's Pack.

Our new A Level textbook is written in the straightforward, easy-to-grasp style for which Pat Heathcote and Rob Heathcote are well-known. Each chapter in the book corresponds to roughly one lesson, and contains questions and exercises which can be done in class, as well as questions at the end of each chapter which can be set as homework. Answers to all questions are provided in downloadable pdf format available free to teachers from the PG Online website. This book is divided into twelve sections comprising 72 chapters, which together provide complete coverage of the new AS and A Level course. Two short appendices contain A Level content that could be taught in the first year of the course as an extension to related AS topics. The specification is written in such a way that AS and A Level students can be taught together. Programming solutions within the textbook are all written in pseudocode to suit all practical languages being taught alongside the theory. To accompany this textbook, PG Online also publishes a series of six downloadable teaching units. Each topic in a unit consists of a PowerPoint presentation, teacher's notes, worksheets, homework sheets and a final assessment test with exam-style questions. Pat Heathcote and Rob Heathcote both have years of experience as teachers, authors and examiners.

The aim of this book is to provide a comprehensive and accessible text for students, covering Papers 1 and 2 in the latest OCR GCSE J277 Computer Science specification. It will be invaluable both as a course text and in revision for students nearing the end of the course. It is divided into eight sections, each broken down into manageable chapters of roughly one lesson. Sections 6 and 7 of the textbook cover algorithms and programming fundamentals with a theoretical approach to provide students with experience of writing, tracing and debugging pseudocode solutions without the aid of a computer. These sections would complement practical programming experience. Each of the eight sections cover one of the major topics in this course, and each subtopic contains sample examination questions from past papers, which can be set as homework.

This book is intended for individuals and students learning to program. You may already have done some programming in other languages, but not be familiar with Python. Novice programmers should work through the book sequentially, starting at Chapter 1. It will also be a useful reference book for students on a programming course or anyone working on a programming project. It teaches basic syntax and programming techniques, and introduces three inbuilt Python modules: "> Tkinter, used for building a graphical user interface, which is an option that some users may like to include in their project work. "> SQLite, which enables the creation and processing of a database from within a Python program. This provides an alternative to writing to a text file when data needs to be stored and retrieved "> .pdb, Python's debugging module, which can be used to help find elusive logic errors. Questions and exercises are included in every chapter. Answers to these as well as over 120 Python programs for all the examples and exercises given in the book may be downloaded from www.pgonline.co.uk. These programs enable users of the book to try out the in-text examples and check possible solutions to the exercises.

This book is a straightforward guide to the Visual Basic programming language and programming techniques. It covers all of the practical programming skills that may be required up to GCSE level and for those at AS Level with limited exposure to VB. It is suitable for both experienced programmers, students or individuals with very little or no programming experience in other languages. It teaches basic syntax and programming techniques and introduces a number of useful features such as: Developing graphical user interfaces (GUIs) with the visual designer in visual studio. SQLite, which enables the creation and processing of a database from within a Visual Basic .NET program. This provides an alternative to writing to a text file when data needs to be stored and retrieved. The Visual Studio debugger, which can be used to help find elusive logic errors.

MS Word is one of the most useful applications for anyone who uses a computer in their studies, at work or at home. However, a great many people have never been taught the best or most efficient way of performing simple tasks like creating a neat list in columns, placing images exactly where they want them or quickly changing text styles throughout a document. Additionally, many users struggle to adapt to newer versions of Word, and need help learning the best ways of doing familiar tasks or using new facilities introduced in Word 2013 and subsequent versions. This book assumes that you know the basics of how to create and edit a simple document, and shows you how to do much, much more. The mysteries of the tabs and ribbon interface used in Word 2013 and Word 2016 are laid bare and you will soon find you can do all you wanted and more in a fraction of the time it took before. It really is all very simple once it's explained! Find out why you never again need to press the space bar two or more consecutive times when creating tabular lists, how to type French accents or fractions, how to create reports with different headers and footers in different sections of the document, how to group and manipulate graphics, draw lines that are precisely horizontal or vertical, and use keyboard shortcuts to speed up common tasks. How to use this book You can work through the book from start to finish, pick out a particular chapter or simply use the book as a reference. A comprehensive index will help you find the information you are looking for.

The aim of this book is to provide comprehensive coverage of topics in Unit 1 of the BTEC Level 3 course in Information Technology in an interesting and approachable manner. If you are studying this course, you need to notice, read about, experience and analyse the impact and implications of current and emerging digital technologies. Examples and case studies from scenarios and events that have recently been in the news are used to bring the subject to life. Reading and discussing articles from quality newspapers, whether printed or online, discussing relevant TV documentaries, noticing and analysing the use of digital technology in countless aspects of life, as well as learning from a textbook, are all going to contribute to a successful exam result. The book is divided into six sections corresponding to the six Learning Aims outlined in the specification, complementing each of the PG Online teaching resource packs. These sections are divided into between four and eight chapters, each containing material that can be covered in one or two lessons. The chapters have in-text questions which can be used as discussion points in a lesson. An extra chapter at the end of Learning Aim B on "Drawing System Diagrams" will be useful for students faced with a question on the exam for which they are required to draw such a diagram. In addition to almost 100 in-text questions and discussion points, there are over 80 end-of-chapter exercises that are designed to give practice in answering exam-style questions, using command words such as state, describe, explain, analyse. As much practice as possible is needed in answering such questions and getting feedback from the teacher so as to understand how to gain the maximum possible marks in the final exam.
