Mobile phones and tablets utilizing a specific architecture, designated by the processing capability of their central processing unit (CPU), enable applications designed for that architecture to function. These devices process data in chunks of a particular size, and the applications built for them are compiled accordingly. As an example, an older phone might use a CPU designed to handle smaller units of information, and therefore, requires applications built to the same specifications.
The significance of this older architecture lies in its historical prevalence and continued functionality, especially in legacy systems and emerging markets. Although now largely superseded by newer technologies, its support remains relevant for compatibility with older applications and cost-effective devices. Furthermore, its existence highlights the ongoing need for developers to consider compatibility across various device generations.
