Information Technology: An Introduction for Today’s Digital World introduces undergraduate students to a wide variety of concepts they will encounter throughout their IT studies and careers. The book covers computer organization and hardware, Windows and Linux operating systems, system administration duties, scripting, computer networks, regular expressions, binary numbers, the Bash shell in Linux, DOS, managing processes and services, and computer security. It also gives students insight on IT-related careers, such as network and web administration, computer forensics, web development, and software engineering. Suitable for any introductory IT course, this classroom-tested text presents many of the topics recommended by the ACM Special Interest Group on IT Education (SIGITE). It offers a far more detailed examination of the computer than current computer literacy texts, focusing on concepts essential to all IT professionals—from operating systems and hardware to information security and computer ethics. The book highlights Windows/DOS and Linux with numerous examples of issuing commands and controlling the operating systems. It also provides details on hardware, programming, and computer networks. Ancillary Resources The book includes laboratory exercises and some of the figures from the text online. PowerPoint lecture slides, answers to exercises, and a test bank are also available for instructors.

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.

This is a brand new book that provides comprehensive yet concise coverage of all the topics and disciplines covered in the new AQA 8552 Design and Technology (9-1) specification, written and presented in a way that is accessible to teenagers and easy to teach from. It will be invaluable both as a course text and as a revision guide for students nearing the end of their course. It is divided into neat sections covering every element of the specification. Sections 5A to 5F of the textbook cover each of the six specialist technical areas. These sections would complement practical classroom experience. Solutions to all questions and exercises are provided in a free teacher pack available on our website. To accompany this textbook, PG Online also publishes a series of 12 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 practice questions. Each topic within a unit is expected to be taught over several lessons in a week. Units are sold as a lifetime site licence and may be loaded onto the school's private network or VLE.

Learn to program fast in 155 challenges, 54 examples and 85 pages This book is a 'gamified' approach to Python, aimed at supporting GCSE and KS3 students, with complete coverage of the GCSE programming requirements. There's no substitute for practice when it comes to learning a new skill! Python syntax is simple to learn, but becoming an expert in writing programs to solve different kinds of problems takes a bit longer. That's why this book has a short explanation of each new statement or technique, followed by one or more examples and then loads of practice challenges. Some of the challenges will take you only a minute or two, using the Python Interactive window to try out new statements and get immediate results. As you get further into the book, you will be challenged to write programs to perform different kinds of tasks - for example to find the results of a calculation, write a program for a simplified cash machine, sort a list of items into alphabetical order, or to record data in a text file to be read, formatted, and printed. The programming solutions to some challenges have been helpfully simplified for an inexperienced programmer to modify rather than to write from scratch. This builds your confidence in problem-solving. That's why 35 challenges consist of partially written programs for you to complete.
