I want to register a domain name but do want any server space. My PC should act as a server. is that possible

It's possible, but not that simple.

First of all, you'll have to make sure your computer is running and is online 24/7. Otherwise when your computer is offline, people wouldn't be able to access your web pages.

To set up the web server you'll also need some basic technical knowledge. The following are some technical requirements that you need to do / check:

- Make sure your ISP doesn't block inbound connections to port 80. This is the port that people connect to when they try to open your web page.

- Download and install a web server. A popular one is Apache (http://httpd.apache.org). For Windows, IIS is an alternative, but I recommend Apache, because of its popularity (so it's easy to get help when you need it) and because it's easy to play around with the configuration to suit your needs.

- Set up your LAN so that it accepts inbound connections to port 80. If you have a firewall, you'll need to unblock that port (if it's blocked). If you have a router, you'll need to forward inbound port 80 connection to the computer that has the web server installed.

- If you are given static IP address by your ISP, you can simply point the domain name to your IP address. Otherwise if you have dynamic IP, you'll have to use the service of something like DynDns ( https://www.dyndns.com ) so that the domain name will always point to your current IP address.
