5. Why is it recommended to use relative addresses: For example, there is an "index.htm" file, which references some pictures in the "image" directory. If you use "relative addresses" when referencing these images, you only need to upload the original set of things to the new space when you "move". Because the relative positional relationship between the files has not changed, these addresses are still valid. However, if an "absolute address" is used when inserting a picture, the space address changes and the picture path at the reference point also changes. Of course, "absolute addresses" are sometimes used, such as friendly links to other homepages, etc.
