The term "obsolete" refers to something that is no longer in use or has fallen out of favor due to advancements or changes in technology, culture, or society. For example, items like typewriters and floppy disks are considered obsolete because modern alternatives, such as computers and cloud storage, have replaced them. Obsolescence can occur in various fields, including technology, fashion, and even language. When a product or idea becomes obsolete, it may still exist but is often seen as outdated or inefficient. This can lead to a shift in consumer preferences and the eventual discontinuation of the obsolete item.
