I would prefer to give path of google. for more detailed answer you can go here

The google api servers are distributed across the world instead of my single server location: Closer servers usually means faster response times for the visitor.
Many people choose to have JQuery hosted on Google, so when a visitor comes to my site they may already have the JQuery script in their local cache. Pre-cached content usually means faster load times for the visitor.

Best is to include the google link.

But If for some reason you will develop on a machine without internet access, you should download it on your server.

If you are working on local then

download a copy and use it.

Pros of having Google host jQuery for you:

Some of your users may already have the script in their caches, as other Web sites may use the same URL to load the same code.
Otherwise, Google's server may be geographically closer and therefore latency could be lower.

Cons of having Google host jQuery for you:

Connecting to ajax.googleapis.com might require an additional DNS request, increasing load time.
For intranet sites, latency will be higher than that of connecting to a server on the same local network.
If Google is down (or your site is an intranet site and your Internet connection is down), the script might not load at all.
- If you load the script at the top of a page, the page might be unreadable until the connection to Google times out.
- Some employers' restrictive firewalls block all connections to Google, including those to Google APIs.
If Google gets hacked, they could deliver malicious JavaScript that impacts your site. Malicious code would have access to anything your users can get to through your site.
Google would know your users' IP addresses, which may be a privacy concern.

As for Stack Overflow itself, they do use Google's service despite all the disadvantages.

I think the best practice is to have a fallback in case the CDN is down :

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
// Fallback
<script>!window.jQuery && document.write(unescape('%3Cscript src="js/libs/jquery-1.8.3.js"%3E%3C/script%3E'))</script>

That comes from HTML5 Boilerplate.
