What is prefetch page resources?
Prefetching allows a browser to silently fetch the necessary resources needed to display content that a user might access in the near future. The browser is able to store these resources in its cache enabling it to deliver the requested data faster.
What does DNS prefetch do?
DNS prefetching is an attempt to resolve domain names before a user tries to follow a link. This is done using the computer’s normal DNS resolution mechanism; no connection to Google is used. … When we encounter hyperlinks in pages, we extract the domain name from each one and resolving each domain to an IP address.
What is Preconnect?
What is preconnect ? # preconnect allows the browser to set up early connections before an HTTP request is actually sent to the server. Connections such as DNS Lookup, TCP Handshake, and TLS negotiation can be initiated beforehand, eliminating roundtrip latency for those connections and saving time for users.
How do I Preconnect to origins?

What is domain prefetching and how does it help with performance?
A DNS Prefetch is a resource hint to make a DNS lookup for a domain the browser has not yet determined needs to be made. This can improve performance because when the browser does need to make a request for a resource, the DNS lookup for that domain has already occurred.
