Homonym: cache (Storage)
A cache is a small, high-speed storage area that temporarily holds frequently accessed data to improve performance. It allows systems, like computers and web browsers, to retrieve information quickly without needing to access slower storage options, such as hard drives or the internet.
Caches can be found in various forms, including CPU caches, which store data for quick access by the processor, and browser caches, which save web page data to speed up loading times. By using caches, devices can operate more efficiently and provide a smoother user experience.
