Pronounced at sign or simply as at, this symbol is used in e-mail addressing to separate the user’ name from the user’s domain name, both of which are necessary in order to transmit emails. For example, the e-mail address [email protected] indicates that the user named webmaster receives e-mail “at,” or “@,” the www.webopedia.comdomain.
