title: What is the benefit for using "form" tag?
body: <p>I don't understand what is the benefit of using <code>&lt;form&gt;</code> tag.</p>
  
  <p>Look at the following code:</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
  &lt;script&gt;
  function check(browser) {
      document.getElementById("answer").value=browser;
  }
  &lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
  
  &lt;p&gt;What's your favorite browser ?&lt;/p&gt;
  
  &lt;form&gt;
  &lt;input type="radio" name="browser" onclick="check(this.value)" value="Internet Explorer"&gt;Internet Explorer&lt;br&gt;
  &lt;input type="radio" name="browser" onclick="check(this.value)" value="Firefox"&gt;Firefox&lt;br&gt;
  &lt;input type="radio" name="browser" onclick="check(this.value)" value="Opera"&gt;Opera&lt;br&gt;
  &lt;input type="radio" name="browser" onclick="check(this.value)" value="Google Chrome"&gt;Google Chrome&lt;br&gt;
  &lt;input type="radio" name="browser" onclick="check(this.value)" value="Safari"&gt;Safari&lt;br&gt;
  &lt;br&gt;
  Your favorite browser is: &lt;input type="text" id="answer" size="20"&gt;
  &lt;/form&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>If I'm removing the tags: "form" and "/form"
  I'm getting the same results. so what is the different ?</p>
  
  <p>Thanks</p>
