How to turn a home computer into a file server

Whether you use routing or direct dialing, you can see what you use to build a website. After ASP, PHP or JSP successfully installed the "Web Server", windos200 does not need to set anything else. Xp may need to set something up. If you have a dial-up connection, the external network can directly enter your IP to access it. But pay attention to the port of your website server, the default should be 80, unless you change it. If you are a router, you should put your website server in the forwarding settings of the router. Regarding fixed IP, either you apply for fixed IP from ISP, which costs a lot of money and is unnecessary. Or you can buy that kind of domain name transfer service, which costs tens of dollars. You can install the software they provide into your computer, enter the domain name, and then you can transfer it to your computer, provided that your computer is turned on. Your question has nothing to do with your question. My answer to your question has been very detailed, so I won't say much.
