Hello Shariq,
apex:commandLink:
A link that executes an action defined by a controller, and then either refreshes the current page, or navigates to a different page based on the PageReference variable that is returned by the action. An <apex:commandLink> component must always be a child of an <apex:form> component.eg.
<apex:commandLink action="{!save}" value="Save" id="theCommandLink"/>apex:outputLink:
A link to a URL. This component is rendered in HTML as an anchor tag with an href attribute. Like its HTML equivalent, the body of an <apex:outputLink> is the text or image that displays as the link. To add query string parameters to a link, use nested<apex:param> components.eg.
<apex:outputLink value="https://www.salesforce.com" id="theLink">www.salesforce.com</apex:outputLink> -
Apex:outputLink – The <h:outputLink> renders a fullworthy HTML <a> element with the proper URL in the href attribute which fires a bookmarkable GET request. It cannot directly invoke a managed bean action method.
<apex:outputlink value="https://www.google.co.in"> Google </apex:outputlink>
<apex:outputlink value="/{!r.Id}"> {!r.Name} </apex:outputlink>
apex:commandLink – The <h:commandLink> renders a HTML <a> element with an onclick script which submits a (hidden) POST form and can invoke a managed bean action method. It's also required to be placed inside a <h:form>.
<apex:commandLink value="Google" action="https://www.google.co.in"/>
<apex:commandLink value="Delete" action="{!dodelete}">
<apex:param name="eid" value="{!E.Id}" assignTo="{!rId}"/>
</apex:commandLink> -
Hi
Apex:outputLink: A link to a URL. apex:outputLink component is rendered in HTML as an anchor tag with an href attribute. Like its HTML equivalent, the body of an <apex:outputLink> is the text or image that displays as the link. To add query string parameters to a link, use nested <apex:param> components.

<apex:outputLink value="https://www.salesforce.com" id="theLink">www.salesforce.com</apex:outputLink>
