A B-Tree is a way of organizing data that can help a computer find and store information more quickly. A B-Tree is made up of "levels" or "levels of information". Each level is made up of categories of data that are connected to each other, similar to how stairs are connected together. Data at the same level are connected in a tree or branch-like structure. Each level holds different information. As you go up in the B-Tree, the categories become more specific and the information is easier to find. The B-Tree also helps your computer store information efficiently by not putting too much information in one location. It's like putting your toys in different boxes – it's easier to find what you need!
