Cookies are files, often including unique identifiers, that are sent by web servers to web browsers, and which may then be sent back to the server each time the browser requests a page from the server.
Cookies can be used by web servers to identity and track users as they navigate different pages on a website, and to identify users returning to a website.
Cookies may be either “persistent” cookies or “session” cookies. A persistent cookie consists of a text file sent by a web server to a web browser, which will be stored by the browser and will remain valid until its set expiry date (unless deleted by the user before the expiry date). A session cookie, on the other hand, will expire at the end of the user session, when the web browser is closed.

__utmz stores where a visitor came from (search engine, search keyword, link)
__utma stores each user’s amount of visits, and the time of the first visit, the previous visit, and the current visit (presumably partly for double checking of this information).
__utmb and __utmc are used to check approximately how long you stay on a site: when a visit starts, and approximately ends (c expires quickly). If you look at cookie state changes (e.g. using firecookie), you will see these change regularly.
