Abstract: An operation method of a server for updating firmware includes: generating a first delta file including a plurality of blocks based on a plurality of update areas included in a first version firmware; generating a second delta file by repositioning the plurality of blocks included in the first delta file such that a plurality of unit blocks are generated by grouping control blocks, difference blocks, and extra blocks, each of which corresponds to the plurality of update areas, respectively; generating a plurality of swap blocks based on extra blocks among the plurality of blocks; and generating a third delta file by adding the generated plurality of swap blocks to the second delta file.
