Detailed explanation-1: -OCSP and CRLs are both used to verify the revocation status of TLS certificates, but the way they work is very different. While a CRL lists all the revoked certificates, OCSP gives the revocation status of the single website requested by the browser.

Detailed explanation-2: -Since an OCSP response contains less data than a typical certificate revocation list (CRL), it puts less burden on network and client resources. Since an OCSP response has less data to parse, the client-side libraries that handle it can be less complex than those that handle CRLs.
