For ix86 programming, sometimes it is necessary to change from the real mode to the protection mode (for example, to access extended memory in the DOS era, or to write pilot code, of course, if you program in a 32-bit operating system, you won't be
Reading Tips: with the advent of a low-cost 64-bit platform, coupled with the falling price of memory and hard disk, it is undoubtedly a great effort for 32-bit programs to port 64-bit hardware, those scientific operations, databases, and programs

Even if you haven't compiled advanced applications for nanoelectronics, aerodynamic, Molecular static, cell lifecycle modeling, and so on, maybe the following 32 rules are as follows, it will help you port programs to a higher-level
Currently, Windows operating systems can be divided into two categories: 32-bit and 64-bit (64-bit also distinguishes x86_64-bit and itanium), and Oracle clients are also differentiated.
Some problems often occur during installation and development.
