This document provides an overview of common computer hardware and software components. It describes the central processing unit, memory, storage devices, ports, and other internal and external parts of a basic computer system. It also explains operating systems, applications, and basic functions like dragging and dropping.
Multimedia is a combination of text, graphics, audio, video and animation that is delivered interactively to users through electronic or digital means. It combines multiple forms of information into an integrated multi-sensory interactive application or presentation to inform, educate, train, or entertain users. The five basic elements of multimedia are text, graphics, audio, video and animation. Common software used to create each element includes Word for text, Photoshop for graphics, Audition for audio, Premiere for video, and Flash for animation.
1. An information system is a system composed of people and computers that processes or interprets information.
2. The main elements of an information system are hardware, software, data, processes, people, and feedback.
3. Hardware includes the computer and support equipment like input/output devices, storage devices, and communication devices. Software includes computer programs and manuals, while data are the facts used by programs to produce information.
