The question comes from an in-depth understanding of computer system exercise 2.67. The question Description: Write a function int_size_is_32 (). When running on a 32-bit machine with an int value, 1 is returned, and 0 is returned in other cases, the sizeof operator is not allowed.
First try:
Int is_int_32 () {int set_msb = 1
Generally, it runs well, but when running on a 32-bit machine like Sun P
In a 64-bit Windows operating system, a 64-bit Windows operating system uses a redirection mechanism in order to be compatible with 32-bit programs. The goal is to allow 32-bit programs to operate in 64-bit operating systems not only to manipulate key file folders and critical registry but also to avoid conflicts with 64-bit programsFor more information, see the redirection mechanism of

As we all know, the maximum memory support for 32-bit computers is 4G, how does this 4 G come from? Does 4G memory represent data with a maximum storage data of 4G? Vaguely remember to learn how to calculate the principle of the concept has been clear, but now in retrospect and some vague. First, the 32-bit computer refers to the computer memory addressing bus is 32

This blog summarizes and summarizes some methods to check whether the Linux system is 32-bit or 64-bit. A lot of content comes from the blogs of online users. This article only sorts out and sorts out this knowledge so that you can view it whenever you forget it.

32-bit and 64-bit refers to the number of operating system bits, mapped to the C language, the most intuitive is the pointer type occupies the number of bytes.1 32-bit system:The address occupies 32 bits, so the pointer type also accounts for 32 bits, or 4 bytes.2 64-bit system:The address occupies 64 bits, so the poin
a netizen reflects that his 32-bit win 7 can not use 4G of memory. In fact, 32-bit Win7 and Vista are not allowed to use 4G memory , that there is no 32-bit Win7/vista also use 4G of memory it? The answer is yes, but doing so is likely to undermine the stability of the system.
Let's take a look at how to get 32-bit
