When you put your computer in stand-by mode below are the things that happen in general-

1)Your processor goes into sleep mode(In this mode it stops processing but saves its state)

2)RAM goes into sleep mode(It saves state,and read write are not allowed to save power-Depends on your mother board)

3)Devices like mother board and keyboard or speakers are cut off power.

All this saves power and also saves overworking of your devices.

And so it is a good practice to out your computer into Standby mode when leaving it for short period of time.

The POP protocol, by default, downloads messages to your computer and then deletes them from the mail server. If you leave all of your email on a primary computer (for example, your office computer) but want to have access to recently received email on a secondary computer (a home computer), you should leave your messages on the server for a limited period of time.

Stand by uses less energy that running the appliance. But if you are not using it, like a computer, you save all the energy by turning it off at the wall. One machine on standby doesn't use a lot of electricity, but billions all over the world, left on all the time, use a vast amount of energy.
