CCNA OSPF question concept help

Hi guys, I am studying for my CCNA and am in the section of OSPF. It is going great but i have a question, what is the difference if i add a specific network IP int address, vs the subnet. For ex, R1 has 172.16.10.1 on int g0/0. What would be the outcomes if I add these two commands:

network 172.16.10.1 0.0.0.0 area 0

network 172.16.10.0 0.0.0.255 area 0

I think the differnce is the first would be specific, and the second would allow all other nodes in that subnet?

I just cant grasp the concept well enough where in the lab, i would know the difference of when being asked to do either.

Hope this makes sense and thank you for the help[ in advanced
