of memory. Fifth, the popularity of software varies. Currently, 64-bit commonly used software is much less than 32-bit commonly used software. The principle is simple: there are fewer users using 64-bit operating systems. Therefore, software developers must consider the "input-output ratio" and invest limited funds in software for more users. This is also an important reason for the relatively high price o

Guide:? An executable file can be a binary file with a different format, or it can be a script for a text.
