The amount of internal memory that a tablet has affects how much can be stored on it. This memory is used to store the operating system and is also needed for at least part of every installed app. Downloaded content, such as books and videos, and user created content, such as photos and videos shot using the camera, can be stored on a memory card, but the internal memory is the most important.
The iRulu 7″ Kids Tablet comes with 16 gigabytes (GB) of internal memory. It also has 1 GB of RAM, that being used to run the tablet, and has a memory card slot that can take memory cards up to 32 GB in size.
