What is the use of Public group in Salesforce

Groups are sets of users. They can contain individual users, other groups, the users in a particular role or territory, or the users in a particular role or territory plus all of the users below that role or territory in the hierarchy.

There are two types of groups:

§  Public groups—Only administrators can create public groups. They can be used by everyone in the organization.

You can use groups in the following ways:

§  To set up default sharing access via a sharing rule

§  To share your records with other users

§  To specify that you want to synchronize contacts owned by others users

§  To add multiple users to a Salesforce CRM Content library
