Shutting off hot water?

If I shut off the main water valve will that shut off the hot water too? The reason I'm asking is I was looking over the boiler system last night and I noticed that the water comes in from the cold water pipe into the tank. Pipes then come from the boiler(to heat it up I guess) and then a pipe comes out with the hot water into the house system. The off things [to me] was there was no shut off valve so it got me think if it can be shut off. Does the hot water pressure come from the same source as the cold?

The main valve coming into the house should shut off all water
In some cases they are so old they need to be replaced as theyw ill not shut off the water

Sounds like your boiler also provides hot water
So shutting off any input to the boiler will shut off hot water
My boiler has a separate shut off valve, I do not need to shut off all water to the house
So even if there is water in the tank it wont flow of the main valve is off?
The tank I'm talking about is about 4.5' tall and about 2.5-3' wide. A big blue water tank next to the boiler.
