Tethered Jailbreak
Means that every time you phone reboot, restart or your phone losses power it will loose the patched kernel an the jailbreak will become function-less to to regain the full functionality and jail-broken state you will have to reconnect your device too computer and run the tool which was used while jail breaking your iphone and have to use "just boot" or "boot as tethered" option on your jailbreack tool which will again patch the kernel temporarily until next reboot or boot.

Untethered Jailbreak
Simply it is just opposite to Tethered Jailbreak here the kernel is patched permanently so you don't have to connect your device every time to computer on power loss or reboot or even after hard reset. so it can be considered as ideal solution
