There are concepts of bit, byte, word and double word in the program, such as11111165438+. One of 1 is 1 bit, one byte =8 bits, and one word = two bytes = 16 bits, which is the above number. If those two words are two words, that is, 32 bits, the data of 16 bits can represent 0~65535 (decimal) and 32 bits.

I hope the above content can help you understand this concept!
