Run show config and look at the config for the DHCP shown as below:

p dhcp pool default_scope
   network 192.168.1.0 255.255.255.240
   default-router 192.168.1.1
   dns-server 192.168.1.20
   netbios-name-server 192.168.1.7
   lease 2

Lease 2 means lease is for two days.  If it shows lease 0 2 then it is set for two hours.  If you disconnect a PC (lets say 5 minutes) and reconnect, it will pick an IP from the pool and the lease starts all over again.  If the machine is left on, the PC will ask for a renewal after 1 day.

show ip dhcp binding - shows ip add which are leased right now

show ip dhcp conflicts - shows 3 machines with "Gratuitous ARP" as a detection method and no conflicts.
