Diffrence between GPT and GPO

GPO - Group Policy Object - Refers to the policy that is configured at the Active Directory level and is inherited by the domain member computers. You can configure a GPO – Group Policy Object - at the site level, domain level or OU level.


GPT - Group Policy Templates: The GPT is used for file-based data and stores software policy script, and deployment information. The GPT is located on the system volume folder of the domain controller. A GPO can be associated with one or more Active Directory containers such as a site, domain, or organizational.
