Your PC (and any other device on your home network) is assigned an IP address on your private network, usually beginning 192.168.x.x. You can make that static yourself (i.e. force your PC to use a given IP address instead of being assigned one by the router). This IP address can only be used by devices on your internal network.
Separately, your broadband router will be assigned an IP address (usually dynamic) by your Internet Service Provider. This is the IP address used to reach you from the wider internet or the IP address other devices on the internet will see. If hosting a server on your PC, you'll need to configure your router to do port forwarding. If your ISP gives your router a dynamic IP, you can't make it static yourself.
