Computer Programming Software Terms, Glossary and Dictionary
Helper applicat ion is an external viewer program launched to display content retrieved using a web browser. These applications commonly let you see and hear video and audio files, as well as view specialized text files or virtual reality models. Windows Media Player, QuickTime, Shockwave, CosmoPlayer, and RealAudio are examples of helper applications. Another common term for these programs is "plug ins," because they supplement the capabilities of your browser, and only run when they are needed to display files.
