What is your domain/forest structure (single domain or multiple domains)
 

There is the standard AGLP/UGLY but those don't always apply.

Universal Group: can contain users and groups (global and universal) from any domain in the forest.  Universal groups do not care about trust.  Universal groups can be a member of domain local groups or other universal groups but NOT global groups.

Global Group: can contain users, computers and groups from same domain but NOT universal groups.  Can be a member of global groups of the same domain, domain local groups or universal groups of any domain in the forest or trusted domains.

Domain Local Group:  Can contain users, computers, global groups and universal groups from any domain in the forest and any trusted domain, and domain local groups frm the same domain.  Can be a member of any domain local group in the same domain.

The short answer is that domain local groups are the only groups that can have members from outside the forest.  And use global groups if you have trust, universal groups if you don't care about trust.

Then when should we need trust and when should we use universal group without trust?

Use global security groups to group user (or computer) accounts with simillar characteristics, for example members of Sales department.

Use domain local security groups to define access to resources (share, NTFS, printer),
for example you would create domain local group "DL ColorPrinter Print" and assign print permission to this group. Then you would put global security group Sales in "DL ColorPrinter Print" group to enable printing for sales department. If marketing department wants to use the same printer you have to create global group Marketing and put this group in "DL ColorPrinter Print" group. This strategy is called A-G-DL-P. Put accounts in global groups, global groups in domain local groups and assign permissions to domain local groups and you will assign permission only once. Everything else happens in Active Directory Users and Computers when you modify groups memberships.

Universal groups should only be used in multiple domain forest. Universal groups are used to nest global groups. Group strategy is then called A-G-U-DL-P.

In shot below are the details
Global Groups:
Use these to group users with similar needs within the organisation, sales people, finance people, managers etc

Domain Local Groups:
Use these to specify access to resources eg database users, Colour Printer Users.

Universal Groups
Use only in mulitiple domains to give forest wide privilages.
