Big-endian

In computing, endian and endianness (pronounced just as spelled) in the most common cases, refers to how bytes are ordered within the memory of your computer. Computer memory is organized just the same as words on the page of a book or magazine, with the first words located in the upper left corner and the last in the lower right corner. The same is also true in mathematics or computer programming when you are diagramming matrices or arrays on a page; with the first element in the upper left corner and the last in the lower right corner, with the indexing of elements being described in similar terms in math and computer programming.
