Is there a difference in how browsers display data retrieved via Ajax compared to non-Ajax methods in PHP?

When data is retrieved via Ajax in PHP, the content is typically returned in JSON format and then dynamically inserted into the webpage using JavaScript. This can result in a smoother user experience as only specific parts of the page are updated without requiring a full page reload. However, when data is retrieved via non-Ajax methods in PHP, the entire page is typically reloaded, which can be slower and less efficient. 

// Example of retrieving data via Ajax in PHP

// PHP file (getData.php) to retrieve data
$data = array('name' => 'John Doe', 'age' => 30);
echo json_encode($data);

// JavaScript to handle Ajax request
$.ajax({
  url: 'getData.php',
  type: 'GET',
  success: function(response) {
    var data = JSON.parse(response);
    document.getElementById('name').innerHTML = data.name;
    document.getElementById('age').innerHTML = data.age;
  }
});
