Memcached

Memcached is like a really big box of toys. Imagine your toys are your website or app's data. Memcached helps your website or app to store its data, and make it easily available and fast to access whenever you need it. Whenever you want to play with a toy, you can just reach into the box and pull it out. Same way, whenever you need to access some data for your website or app, Memcached will fetch it from the box (cache) and give it to you super fast without having to load it from the original storage every time. It's like having a super fast memory that helps your website or app to work faster, without putting too much load on the main storage. It's really helpful for big websites or apps that have tons of data and users.
