Cross-forest trust
child and parent domains
Tree-Root Trust or cross forest trust (windows server 2008 active directory)
Transitive trustA trust that can extend beyond two domains to other trusted domains in the forest.Intransitive trustA one way trust that does not extend beyond two domains.
one needs to make trust between the domains. please check below the different types of the trusts One-way trust One domain allows access to users on another domain, but the other domain does not allow access to users on the first domain. Two-way trust Two domains allow access to users on both domains. Trusting domain The domain that allows access to users from a trusted domain. Trusted domain The domain that is trusted; whose users have access to the trusting domain. Transitive trust A trust that can extend beyond two domains to other trusted domains in the forest. Intransitive trust A one way trust that does not extend beyond two domains. Explicit trust A trust that an admin creates. It is not transitive and is one way only. Cross-link trust An explicit trust between domains in different trees or in the same tree when a descendant/ancestor (child/parent) relationship does not exist between the two domains. Shortcut Joins two domains in different trees, transitive, one- or two-way Forest Applies to the entire forest. Transitive, one- or two-way Realm Can be transitive or nontransitive, one- or two-way External Connect to other forests or non-AD domains. Nontransitive, one- or two-way. Windows 2000 Server supports two-way transitive and one-way intransitive trusts. Administrators can create shortcuts. Windows Server 2003 the forest root trust. This trust can be used to connect Windows Server 2003 forests if they are operating at the 2003 forest functional level. Authentication across this type of trust is Kerberos based (as opposed to NTLM). Forest trusts are transitive for all the domains in the trusted forests. Forest trusts, however, are not transitive.

Domains are divided into kingdoms.
a domain is a bigger category, under the domain are the kingdoms - animalia, plantae, protista, eubacteria, fungi, and archeabacteria
The phases of development are like a ladder that provides steps on be on toward your goal. Whereas Domains of development are the major terms i.e physical, language, cognitive and emotional, etc. For a brief overview of phases of development, you can visit danmonahan.ca/the-6-phases-of-personal-development/
The difference between the server and domains is fairly simple. The server is the system on which the entire functions rest, and the domains are pages within that system. Imagine the server as a neighborhood and domains as houses.
A domain as "a single security boundary of a Windows NT-based computer network. Active Directory is made up of one or more domains. On a standalone workstation, the domain is the computer itself. A domain can span more than one physical location. Every domain has its own security policies and security relationships with other domains. When multiple domains are connected by trust relationships and share a common schema, configuration, and global catalog, they constitute a domain tree. Multiple domain trees can be connected together to create a forest." Domain A Windows domain is a collection of security principals that share a central directory database. This central database (known as Active Directory starting with Windows 2000,[1] Active Directory Domain Services in Windows Server 2008 and Server 2008 R2, also referred to as NT Directory Services on Windows NT operating systems, or NTDS) contains the user accounts and security information for the resources in that domain. Each person who uses computers within a domain receives his or her own unique account, or user name. This account can then be assigned access to resources within the domain. In a domain, the directory resides on computers that are configured as "domain controllers." A domain controller is a server that manages all security-related aspects between user and domain interactions, centralizing security and administration. A Windows Server domain is generally suited for businesses and/or organizations when more than 10 PCs are in use. Trust To allow users in one domain to access resources in another, Active Directory uses trusts. Trusts inside a forest are automatically created when domains are created. The forest sets the default boundaries of trust, and implicit, transitive trust is automatic for all domains within a forest. Terminology One-way trust One domain allows access to users on another domain, but the other domain does not allow access to users on the first domain. Two-way trust Two domains allow access to users on both domains. Trusting domain The domain that allows access to users from a trusted domain. Trusted domain The domain that is trusted; whose users have access to the trusting domain. Transitive trust A trust that can extend beyond two domains to other trusted domains in the forest. Intransitive trust A one way trust that does not extend beyond two domains. Explicit trust A trust that an admin creates. It is not transitive and is one way only. Cross-link trust An explicit trust between domains in different trees or in the same tree when a descendant/ancestor (child/parent) relationship does not exist between the two domains. Shortcut Joins two domains in different trees, transitive, one- or two-way Forest Applies to the entire forest. Transitive, one- or two-way Realm Can be transitive or nontransitive, one- or two-way External Connect to other forests or non-AD domains. Nontransitive, one- or two-way.[18] Windows Server 2003 introduced the forest root trust. This trust can be used to connect Windows Server 2003 forests if they are operating at the 2003 forest functional level. Authentication across this type of trust is Kerberos based (as opposed to NTLM). Forest trusts are transitive for all the domains in the trusted forests. Forest trusts, however, are not transitive
