Introduction  Multimedia is something people can see, hear, touch and read on websites, radio, television, video games, phone applications, retail stores, cinema halls and ATMs. Multimedia can be defined as a combination of picture, text, sound, video and animation. In simple terms, multimedia is the combination of more than one media.
 Multimedia is the medium which provides information to the users in the form of text, audio,video, animation and graphics. The information is delivered to the users by digital or electronic means. When a user is allowed to control the elements of multimedia then it becomes interactive multimedia. Interactive multimedia is called hypermedia when the user is given the structure of linked elements to control it
Meaning and its Usage  Multimedia is a mixture of different forms of media. This includes text, graphics, audio, video, etc. Today, multimedia is found everywhere in educational institutes, offices, airports, railway stations, journalism, creative and entertainment industries such as TV, films, radio, etc., medicine, IT industry, research, etc. The kinds of media components and how they are used in a multimedia program matter a lot.
A music video and sound should be used together as one without another would lose its significance.  Multimedia provides important information in an interactive way with the usage of images, graphics, animation, video and audios.

Categories of Multimedia  Based on how multimedia programs are used, multimedia can be divided into two forms – linear multimedia and non-linear multimedia. In linear multimedia, information is read or viewed in a continuous sequence. Usually, these presentations begin at a predetermined starting point and end at a predetermined end point. They can be automated so that each screen comes after a fixed time interval. Example: Powerpoint presentation is one of the most common examples of linear multimedia.
 On the other hand, non-linear multimedia information is not presented in sequential or chronological manner. Non-linear multimedia programs are usually interactive and require audience interaction.  One of the most common examples of this form of multimedia is the Web.

Generally, multimedia presentations are viewed in person in a boardroom, class, on stage or in an auditorium. They can be transmitted, projected or played on a projector using a media player such as a computer. A live or recorded presentation is called a broadcast.
 Multimedia games can be used in a physical environment with multiple users in an online network, with special effects or with an off-line computer or game system. Interaction in a multimedia program can be increased by mixing multiple forms of media content. However,depending upon the kinds multimedia content available, it may differ online. Global positioning system (GPS) is popular multimedia device used for mapping routes and directions while driving, travelling or hiking
 Multimedia is progressively becoming data-driven and object-oriented which allows applications with cooperative end-user innovation and personalization on many forms of content over a period. For instance, content available on various websites such as photo galleries that have both content and images user-updated, to simulations whose events, animations, illustrations or videos are changeable, enabling the multimedia experience to be changed without reprogramming.
Applications of Multimedia  Multimedia can be used in a variety of ways in myriad fields. A multimedia presentation can be put together in varied formats. Some of the most common applications are given below: Business- Multimedia is used for advertising and selling products on the Internet.

It also saves money of the employers as now they don’t have to pay extra expenses on training or education of their human resources. Multimedia is one of the best ways to provide short-term training to the workers in a company.
Research and Medicine  Multimedia is increasingly used in research in the fields of science, medicine and mathematics. It is mostly used for modelling and simulation. For instance, a scientist can look at a molecular model of a particular substance and work on it to arrive at a new substance. In Medicine, doctors acquire training by watching a virtual surgery or they can simulate how the human body is affected by diseases spread by germs and then develop techniques to prevent it.
Public Access  Public Access is an area of application where several multimedia applications will be available very soon. One of the application is the tourist information system, where a travel enthusiast will be shown glimpse of the place he would like to visit.

Such installation reduce demand on traditional information booths and personnel, add value, and they can work around the clock, even in the middle of the night, when live help is off-duty
Engineering  Software engineers may use multimedia in computer simulations for anything from entertainment to training such as military or industrial training. Multimedia for software interfaces are often done as collaboration between creative professionals and software engineers.
