We will work hard in this class to understand the boldfaced words have I used above since understanding them will allow us to communicate better with each other as we write scripts (and give us a framework from which to master additional scripting languages like PHP and ActionScript). The words will also give us insight into what computers do to compute and even give us insights into how nature works to process information (performing chemical tasks according to our DNA being one of the really beautiful information processing activities in nature).
Unfortunately, each time a user views the page and submits the form, the data travels from the Web browser to the CGI script. The CGI script then processes the data and returns any results to the user in the form of a new HTML-based Web page. This happens every time a user makes changes to the Web form, thus soaking up the server's CPU power and wasting time sending information back and forth across the Internet connection.
The ECMA-262 standard is also approved by the ISO (International Organization for Standardization) as ISO-16262. You can find a PDF version of ECMA-262 at the Mozilla website. You can also find the specification on the Ecma International website. The ECMAScript specification does not describe the Document Object Model (DOM), which is standardized by the World Wide Web Consortium (W3C). The DOM defines the way in which HTML document objects are exposed to your script.
