Image computers store and process large chunks of data representing image information in various forms. This is usually done in the form of arrays, which are contiguous areas of memory with data elements laid out one after the other. The storage layout of arrays simplifies data access when all items are elements in regular arrays. Then the program merely needs to take the position of the element and multiply the y-coordinate by the row length, and to add the x-coordinate and the start address of the array. For images or data arrays with a fixed size, this is a convenient representation.
