There are many different types of multimedia systems, which are usually developed or designed to meet a particular purpose or for use in a certain environment. Home systems, for example, are intended for enjoyment by a relatively small group of people and for use in a fairly small space. There are systems designed for use in the workplace, which may be intended for somewhat small groups and are used in offices for presentations or employee training. Larger systems are developed for use at trade shows and conferences, and are designed to reach a potentially massive audience.
The modular nature of multimedia systems allows many of the same pieces of technology to be used in a variety of settings. A multimedia system is basically a combination of hardware and software used for viewing or displaying different types of media, such as audio and video. Home systems, for example, are usually designed to allow for one or a few people to view programs in a home environment. These often include a television screen or similar monitor, which may be fairly large, and speaker setups that may utilize surround sound and are typically centrally located.
Multimedia systems for use in an office, on the other hand, might utilize multiple monitors and computer terminals, as well as different speaker systems. Depending on the size of the presentation being made, or the materials being covered, a single screen might display an image that is also visible at separate computer terminals. Rather than using a monitor or television screen, this type of system often uses a projector and a screen to produce a large image. For training purposes, systems can be used that allow a single presentation to be made for an entire group, while each individual is at a computer and able to interact with a personal version of the presentation.
There are also multimedia systems that can be used in much larger venues, such as trade shows, conferences, and speaking engagements. These systems use a number of different displays all showing the same images simultaneously. This allows a single speaker to have one large display that he or she refers to while making a presentation, with smaller displays throughout a room that can be more clearly seen by those farther from the main screen. Multiple speakers can also be used in such systems to allow those in a large space to all clearly hear the speaker.
