With technology, the term obsolete describes a computer, hardware, or software considered outdated, no longer useful, or no longer manufactured. For example, the 80286 (286) computer is considered obsolete technology.

Examples of obsolete computer hardware

The following list contains computer hardware and technology considered obsolete or rarely used today and what, if anything, replaced each one.


Although something may be labeled as obsolete, it doesn't mean it's no longer used by anyone. It indicates that most people have moved on to another technology. Also, the technologies may be replaced multiple times by new inventions (e.g., day planner → PDA → smartphone).
