Odin is a ROM Flashing Tools for ALL Samsung smartphones with easiness and comfort. ROM files flashable with Odin come with .tar extension. Most of the ROMs you are going to flash with Odin are the official stock Samsung ROMs (or leaked stock ROMs). Custom ROMs are rerely flashable by Odin because they come with .zip extension that Odin does not recognize (it recognizes .tar files).
There are various ROM .tar files for various Samsung smartphones that require various (again) methods of flashing with Odin. Please ALWAYS refer to the sticky guide threads in your phone’s designated XDA subforum and the first post in the topic of the ROM you are going to flash on how to EXACTLY flash the ROM’s .tar files with Odin to your phone. If after reading those threads you are still in doubt, feel free to ask questions in your phone’s designated Q&A subforum (Questions & Answers). Doing that will save you from damaging your phone!
Here (link) is a very good GENERAL guide made by Intratech on how to use Odin with various .tar and .pit files.
You will learn there what are CODE/PDA, PHONE/MODEM and CSC .tar files, what are .pit files and what all Odin switches mean and when to use them.
