Obsolete technology refers to devices, systems, or methods that are no longer in use or have been replaced by more advanced alternatives. Examples include typewriters, floppy disks, and CRT monitors. These technologies often become outdated due to rapid advancements in innovation, making them less efficient or functional compared to newer options. As technology evolves, the need for older devices diminishes, leading to their obsolescence. This can result in a lack of support, spare parts, and compatibility with modern systems. Understanding obsolete technology helps us appreciate the progress made in fields like computing and communication.
