Users can define their own XML tags in a DTD, Data Type Declaration. In the following example, we are defining various tags to describe a stock quote. If all brokers could agree on the DTD for stock quotes, it would be relatively easy for them to share data and do business with each other.
Sample DTD
Sample XML Document<!ELEMENT stock-quote (symbol, price+, when)> <!ATTLIST stock-quote market (NYSE|NASD|AMEX) "NYSE"> <!ELEMENT symbol (#PCDATA)> <!ELEMENT price (#PCDATA)> <!ATTLIST price type (ask|bid) "ask" value CDATA #IMPLIED > <!ELEMENT when (date, time)> <!ELEMENT date (#PCDATA)> <!ELEMENT time (#PCDATA)>
<stock-quote market="NYSE">
<symbol>IBM</symbol>
<price type="ask" value="84.25"/>
<price type="bid" value="85.00"/>
<when>
<date>8/5/2005</date>
<time>12:13PM</time>
</when>
</stock-quote>
The RSS feed describing our class blog
This is the RSS feed describing our class blog. Note that it is an XML document with many application-specific tags like <tagline>, <author>, <name>, <created>, <modified>, <title>, and <content> that denote semantics rather than the way something is to appear. The inventor of RSS had to devise a DTD to describe documents like this.

At the start of the excerpt he is talking about the ARPANet. The ARPANet was a single network, like a large LAN. The next step was to inter-connect multiple networks, to create an inter-network. Kahn and his colleague Vint Cerf invented TCP/IP to do that. The initial goal of TCP (later split into TCP and IP) was to connect the ARPANet with two other networks each of which had different packet sizes, data rates and communication protocols.
