cookies are used to store information about a user on their computer. generally, it's used to track preferences, and allows customization of websites. it also gets used to keep track of shopping cart contents. cookies are used in combination with sessions to track this info.
cookies can not travel between domains as this violates security. if you're seeing the same cookie name on multiple websites, it could be because both sites are using similar application software (that use the same naming conventions).
more likely, it's a coincidence (especially if you're noticing a common cookie name such as userid).
some people freak out about cookies "tracking" their behavior, but if everyone turned off cookies, much of the web wouldn't work. analytics programs require cookies most of the time to track a user through a website. this might sound like an invasion of a user's privacy, but it helps web site builders build better websites, because it allows them to understand the behavior of users and where the problem spots are on a web site.
