The FAT Simulator's objective is to work as a tool for learning the FAT File System. This Open Eduational Resource (OER) contains small texts about FAT 12, FAT 16 and FAT 32. It's intuitive and easy to use in the classroom by professors and students and its content helps the student make a solid and clear understanding of the subject. To deliver all of that, the simulator is made by a interactive light interface, with controllers and responsive colorful tables.

At the top of the website, we find anchor buttons (A) which takes us to the types of FAT's descriptions and characteristics and comparisons as well. We can also find options for language changing (B), “How to Use” and display the OER's“Authors” (D). For each kind of FAT, there is a short text with its main characteristics. In the beggining of the website, to begin a simmulation, you should insert the number of blocks and its size (of each one). After these choices, “Apply Changes”. Then, the card will rotate, showing the representation of the File Table (1), FAT (2) and the disk's blocks (3).The last thing you should do is insert the amount of files as you want, each one with its size and name. These will be organized according to the insertions or remotions made. As the changes are made, the components (1, 2 and 3) are updated. It's possible to hover the mouse cursor over a entry to highlight all entries that correspond to that file.
