Action is a Form attribute that communicates with the common gateway interface (CGI) program to process.

For example, if you entered “bananas” to the following form:

<form action="../processor.cgi">

Please process this:

    <input name=food><br>

    <input type=submit>


The HTML form would send the input “bananas” to the cgi script. To the cgi script, the action would look like: ../processor.cgi?food=bananas

By mid-1997, interstitials were at the top of every advertiser’s want list, but have lost popularity since then.

For example, the decimal number 15 is equal to the hexadecimal number F. In HTML, an RGB color can be designated by
with the first two numerals representing the amount of red, the second two the amount of green, and the last two the amount of blue. If you wanted your background to be red, you could write the code for a body background color as
<body bgcolor="#FF0000">
Black is the absence of all color and white is the presence of all color, so in hexadecimal, black is at the bottom of the system (no red, green, or blue:
and white is at the top (the maximum amount of red, green, and blue:

A router (not to be confused with a bridge) is a data network device that transfers data from one LAN to another. Routers can be hardware- or software-based, though larger applications and faster communication speeds all but require a hardware router. Routers are used in homes and offices with high-speed internet access such as DSL; they serve to connect the local LAN to the high-speed WAN operated by a service provider.
