access by detecting the host field . There are many websites, such as www.sina.com.cn, www.126.com, and so on. Some Web sites are not restricted to access by IP addresses, but when using IP addresses to access the site, the IP address is relocated to the appropriate domain name. If the input http://141.146.8.66 is relocated to the http://www.oracle.com/index.html, the input http://129.42.60.212 will be relocated to http://www.ibm.com/us/ On The ping command can also get the IP address of a doma

The difference between a relative path and an absolute path is that the concept of absolute and relative paths is involved in the HTML whenever a file is involved (such as hyperlinks, images, etc.). 1Absolute path Absolute path refers to the path that the file really exists on the hard disk.

It's better to learn a language that is different from the language you use everyday. For exa
