Some things you should know is that when you root, you void your warranty! However when you un-root your warranty isn't voided anymore, as long as you don't tell them you rooted in the first place 
What is rooting?
Rooting your phone is the process of modding the OS on your device so you can have complete control over it.
Which means you can bypass things that the carriers/manufacturers put on your phone to limit your device. With rooting you can extend system functionality, and even upgrade it to a custom flavor of Android.
So basically you become the Administrator of your android device.
Rooting Guides/Tutorials!
There are a few different ways on rooting your android device. It depends on your device really.
Here are a few possible ways. I'll post multiple videos, and text tutorials. (more than enough, so you get the point!)

Rooting benefits?
Full Control Over Android! - pretty much explained when I explained what rooting was.
Back Up And Restore The Whole System! - You can back up/restore your entire androids software.
Save Space On Your Phone! - You can partition space for certain things.
Run Special Applications! - run apps like call block, terminal emulator, rom manager, rom toolbox, etc.
Install Custom ROMs! - Installing a custom rom! This is like installing a custom firmware
different UI, more features, and over clocking!
Installing a Custom Rom!
To install a custom rom, you need to be rooted, obviously. You also need to have a custom recovery flashed.
You can find a custom recovery for your phone on google. (if the first few results aren't what you're looking for, your phone probably hasn't gotten a custom recovery or rom yet.)
Once you have a custom recovery, you need to put it on the root of your sd card.
Meaning in NO folders.
After that download any Terminal Emulator. (find one on google play store, they're free.)
then you need to type this into terminal emulator.
When it says (hit enter) dont type that in, (some people probably actually would.) You actually press enter to enter the next command.
su
(hit enter)
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p32
(hit enter)
reboot recovery
After you've gotten a custom rom, just go ahead and back up all of your data. You don't have to do this, however it is HIGHLY recommended. Because if you brick, and don't have a backup, you're fucked.
You can back up your data from the recovery menu you flashed.
Once you've backed up your data, go ahead and download a rom for your phone, MAKE SURE ITS FOR YOUR PHONE!!
Put that zip file on the root of your sdcard, (don't unzip it.)
Before you flash a new rom, wipe everything, data, cache, everything. (even do a factory reset.)
after you've wiped everything,
Scroll to "install from zip" or something along those lines.
The rom will install and you can reboot into a new rom
