The file contains the data that will be transferred to the destination when the instruction is true. The length parameter defines how many words are contained in the file. So the file gives the starting point while the length tells us how many words are needed for the steps. These two parameters are linked together. Let's use this example to simplify the concept. Data are stored in registers. Think about it as a file cabinet. File name is the drawer that contains that specific data we want to use. In this case, drawer one. And the length tells us how many sections are inside the drawer. So the file gives the starting point while the length tells us how many words are needed for the steps. And this is what we mean by the length parameter defines how many words are…
