a is an Anchor tag. The most common anchor being the a href.
b is bold
strong is similar to bold. Without any CSS formatting, most browsers will display text in bold. The difference is that aural browsers (ie those who serf who are blind) do not read the b, but will recognize strong
i is italics.
em (short for emphasis) is for italics what strong is for bold.
strike will put a line through the text.
abbr is for abbreviations.
code usually does a "preformatted" text and uses a font that has even spacing (ie all characters take up the same amount of space).
The other three I think do pretty much the same thing... making a sligthly indented group of text.
