Well to explain, Root in Linux is equivalent to Administrator on Windows. When you boot up Android you are just a regular user. When you root your phone you become Root user. With root you have full access to the system and can do things like make full backups, tether, overclock, undervolt and etc. You have full control of the system.
To prevent apps from taking advantage of root privileges there is something called SU (Super User). This is similar to windows vista/7 UAC where whenever using Root privileges a box pops up asking for permission. You can also permanently let certain apps have root access.
To note though, Rooting != Custom Kernel. But a custom kernel can have root built into it.
As for voiding warranty, kind of But to note 3 things:
1) You can odin back to stock and no one will ever know you rooted
2) If your device breaks to the point where it does not turn on. They will not deny your warranty claim.
3) If you have asuran insurance, that is not voided by rooting.
To note though, only sprint has a problem with you rooting. As long as they don't physically see you rooted there is no problem. As far as Samsung is concerned, rooting does not void your warranty:
