Once you start learning songs with Ultimate Guitar Tabs and Chords, you will notice that sometimes the same chord boxes are presented slightly different - they are not images but simple text. So the same chord above (ver 1) in the text form will look like this. Try to get used to it as you will be seeing them alot.
e||-----|-----|-----|O
B||-----|-----|-----|O
G||--1--|-----|-----|
D||-----|--3--|-----|
A||-----|--2--|-----|
E||-----|-----|-----|O
So basically it looks exactly the same as version 1 on the image above, except done in text. Top 1st line is the high E string (thinnest string), and the 6th line is the low E string (thickest string). That's all you need to know for now.
Finally, the last (and the simplest) way to represent chords is the one below. That method of showing what to play called tabs (tablatures). So the same E chord shown on the image above will look like this now:
|--0----|
|--0----|
|--1----|
|--2----|
|--2----|
|--0----|
The only difference is that numbers you see represent frets where you need to hold the note. In this example, you need to hold 5th (A) string on the second fret, 4th (D) string on the second fret and 3rd (G) string on the first fret and leave other strings untouched. At this moment you may wonder which of the two methods above is used in any specific situation? And how to interpret numbers - are they fingers or frets? The answer is simple - if numbers go under each other (like above) then they represent frets.
