从表面上看,保护模式和实模式并没有太大的区别,二者都使用了内存段、中断和设备驱动来处理硬件,但二者有很多不同之处。我们知道,在实模式中内存被划分成段,每个段的大小为64KB,而这样的段地址可以用16位来表示。内存段的处理是通过和段寄存器相关联的内部机制来处理的,这些段寄存器(CS、DS、 SS和ES)的内容形成了物理地址的一部分。具体来说,最终的物理地址是由16位的段地址和16位的段内偏移地址组成的。用公式表示为:物理地址=左移4位的段地址+偏移地址。-On the surface, protected mode and real mode is not much difference between the two are the use of the memory, Drivers interruption and equipment to deal with the hardware, but there are many differences. We know that in real mode which has been divided into memory, each the size of 64 KB. and the addresses of 16 can be used to express. Memory of the handling of the adoption and register linked to the internal mechanisms to deal with, of these registers (CS, DS, SS and ES) with the formation of a part of the physical address. Specifically, the ultimate physical address is 16 of the 16 addresses and the addresses of migration within the composition. The use of the formula is expressed as : physical address = 4 bits of the address offset address.

基本功能: 一次上传多个文件。 允许得到上传的文件的原文件名,并可以将文件改名存入服务器。 允许设定每次上传文件的总大小,和单个文件的文件大小。 可以设定只被允许文件后缀名列表。 可以设定只被允许的文件类型列表。(注:从文件格式分析,比只分析后缀名更加准确。) 可以设定是否覆盖服务器上同名文件。 可以将所有文件上传到一个文件夹,也可以程序员的需求将文件分类存入不同文件夹。-basic functions : a multiple files to upload. Allowing the documents to be uploaded to the original file name and file name can be credited to the server. Upload allow each document set the total size of individual files and the file size. Can only be allowed to set the file extension from the list. Can only be allowed to set the file type list. (Note : file format, rather than suffix analysis more accurate.) Whether the coverage can set the server name on the document. All documents can be uploaded to a folder, programmers can also demand documents classified into different folders.
