Static IP is permanently assigned to you by your Internet service provider and cant be changed. Whereas your ISP dynamically assigns an IP address to your networking device using DHCP protocol. 

You have to manually configure your server to use the static IP address assigned to you whereas, each time you reboot your computer your dynamic IP will change.

Static IP is costlier than Dynamic IP.

Static IP remains the same over the course of different sessions or even when you reboot the machine. Its useful when that IP needs to be given permission for some website, web app or software, in which case we wont want it to change every time. Dynamic IP will choose any ip within the range and the appropriate gateway. Hope this helps.
