I am small white. I used to use the integration pack. Now I want to go a little deeper. I would like to download Apache separately, most people recommend it. Apachelounge download here, because the version will follow the PHP update. But it still has multiple versions: Apache 2.4 binaries VC14 and Apache 2.4 modules VC14 (http://www.apachelounge.com/download/). How do I choose? Maybe it'll all work. I want to know the difference between them? Ask the

Memory mapping a file does not cause the entire file to be read into memory. In other words, the file is not copied into the memory cache or array. Instead, the operating system retains only a certain amount of virtual memory for the file contents. When you access different areas of a file, the contents of those areas are read and mapped to the memory area as needed. The ones that have never been accessed remain on disk.Use the mmap () function to create a memory-mapped file. The first parameter
