The component that fits the description provided in the question is the apex:actionPoller. This component allows you to specify a time interval for sending an AJAX request to the server, and update a portion of the page or the entire page based on the response received.
The apex:dataList component is used to display a list of records and is not related to sending AJAX requests to the server.
The apex:inlineEditSupport component is used to enable inline editing of records displayed on a page and is also not related to sending AJAX requests to the server.
The apex:image component is used to display an image on a Visualforce page and is not related to sending AJAX requests to the server.
It is important to note that the apex:actionPoller component should be used with caution when working with enhanced lists. Enhanced lists are a feature that provides improved list views for Salesforce records, and using an apex:actionPoller can cause issues with the enhanced list functionality. Therefore, it is recommended to avoid using apex:actionPoller with enhanced lists.
