AS Level and A Level Applied ICT comprehensively covers the requirements of the Cambridge syllabus for AS Level and A Level Applied Information and Communication Technology, and is endorsed by Cambridge. Written in a clear, accessible style by experienced teachers with senior examining roles, the book and free accompanying CD-ROM prepare students for the examination and help them to develop, and learn to apply, a wide range of ICT skills. The book explores the structure and use of ICT systems, including a variety of computer networks, within a broad range of organisations. It fully investigates the systems life cycle, the way in which ICT is applied in the workplace and the impact of ICT on society in general. The CD-ROM, referenced throughout the book, contains raw source-data files and sample model answers for the activities in the practical chapters.
