Jailbreaking on iOS is essentially removing the restrictions that Apple imposes on apps, allowing them to do more advanced things (the Android equivalent of this is rooting). Unlocking a device is removing the carrier restrictions on it, allowing, for example, a Verizon model phone to use an AT&T plan and SIM card. An iPod can't be unlocked, as it does not have cellular network access in the first place.

Rooting an Android device will provide more benefits such as superuser privileges which can be used to get free apps or inApp purchases or can be used to do things like remote into a computer or take screen recordings of your device. Whether or not you believe it is good is a matter of opinion but depending on your actual android device it will have its advantages and disadvantages.
Mobile is a device.

It means you free your iPod Touch from the restrictions and boundaries that Apple has put in place to prevent the installing of 3rd party packages and applications that are not hosted on the Apple App Store. In other words it allows you to get paid or free packages that are hosted on typically Cydia (TM) or Rock [Your Phone] (TM) that may not necessarily be present on the Apple App Store. This process has been an invaluable for users such as myself at getting certain utilities and "tweaks" for the iPod Touch that are yet to be released by Apple. Jailbreaking iPhones can also be invaluable in the sense that it provides the potential to "unlock" the device meaning that other mobile carriers aside from AT&T can be used on it such as T-Mobile** **Only mobile carriers on the same radio frequency as that of AT&T and T-Mobile will work; thus, this means that it is impossible to unlock the iPhone for Verizon and other such carriers at this time in the United States.
Rooting is a term used in Android mobile OS hacking, it provides all the advantages of Jailbreaking (if you're familiar with that) in that you can remove the crap software that the carrier has on by default, make changes to the underlying system code, and even install custom "roms" which can change themes and provide boosts in speed and reliably of the phone.
