All men have a Y-chromosome. Fathers pass this chromosome on to their sons, and they in turn to their sons, forever. Thus all men within a family share an identical Y-chromosome, except for rare changes that happen from time to time.
These rare changes are known as 'markers', because they can be identified in a laboratory. The result of testing several markers is a string of numbers, such as 10-22-14-10-13-14-11-etc. Men of the same family share the the same string of numbers; unrelated men have different strings of numbers.
DNA testing is simple and painless: just a few cells scraped from the inside of the cheek are all that is needed. See photos from the Dorsey DNA project.
There are different types of DNA testing, depending on the purpose- such as to diagnose medical conditions, determine paternity, or for forensics. DNA testing for genealogical purposes is a bit different from testing for these other purposes, and therefore of limited use for anything except genealogy.
The 37 marker test is a good place to start.
If your goals are to confirm (rather than exclude) relationships, consider the 67-marker test.
