Answer:
. Text Materials
Text takes us back to how the internet started, as a means of sending written messages back and forth between researchers. Actually, it takes us back quite a bit further, as pretty much every office memo ever written has mostly consisted of text with perhaps a smidgen of other media types thrown in. Text is still a primary way to transmit information, although nowadays, it is also used to augment other forms of communication, such as a text description of a photograph.
2. Photographs and Other Still Images
Illustrations are perhaps the oldest form of media, harking back at least as far as the prehistoric paintings on cave walls found in various locations around the world. Gutenberg's printing press in the 1400's enabled mass distribution of multimedia works containing both text and images. The growth of electronic communications has meant that older text-only forms of communication could be enhanced with photographs and images as well. Small images such as thumbnails or icons are often used as a visual "entry point" to larger images or more detailed information.
Text and images sometimes combine in a single form, as many software programs make it easy to create text art, a form of lettering that combines a strong visual element as well.
3. Audio Files
Your website or presentation can add sound, from a musical background to a spoken explanation, by including audio files. Even digital cameras, a quintessentially image-based technology, have been engineered these days to record sound as well. Many sound files are compressed, which reduces the file size without greatly sacrificing sound quality. Compressed files require less storage space and stream faster when sent over the internet or transmitted to local systems.
4. Video Presentations
Video presents moving pictures and typically combines images and sound for a compelling multimedia experience. Of course, videos can include text as well, which often appears as captioning for spoken words or as text in an image, as in the case of a slide presentation. Video files are some of the most memory-intensive multimedia applications, but clever streaming methods makes their use practical in everyday use.
5. GIFs and Other Forms of Animation
Animated files occupy a middle ground between still images and video. GIFs, which is an abbreviation for graphic image files, in particular, are small files that present a single image or rapidly display a sequence of a few images to give the appearance of motion.
