Key Differences

The term "obsolete" is commonly used to denote items, practices, or technology that have become outdated and are no longer used, usually because more effective alternatives have been developed. On the other hand, "archaic" often describes things that are not only outdated but are also from a much earlier time, suggesting antiquity and historical significance.
While obsolete items might still be recognized and understood in contemporary contexts, archaic items or terms may not be immediately recognizable due to their age and the significant changes that have occurred since their time of use.
In technology, "obsolete" could refer to software that is no longer supported, whereas "archaic" might describe ancient tools or techniques.
In language, words that are no longer in everyday use but understood by many are considered obsolete, while words that have fallen out of recognition entirely are seen as archaic. This distinction highlights the progression from usage to non-usage and then to historical artifact or relic.
