Internet Code
This list of Internet top-level domains (TLD) contains top-level domains, which are those domains in the DNS root zone of the Domain Name System of the Internet. A list of the top-level domains by the Internet Assigned Numbers Authority (IANA) is maintained at the Root Zone Database. IANA also oversees the approval process for new proposed top-level domains for ICANN. , their root domain contains 1502 top-level domains. , the IANA root database includes 1589 TLDs. That also includes 68 that are not assigned (revoked), 8 that are retired and 11 test domains. Those are not represented in IANA's listing and are not in root.zone file (root.zone file also includes one root domain). Types IANA distinguishes the following groups of top-level domains: * infrastructure top-level domain (ARPA) * generic top-level domains (gTLD) * generic-restricted top-level domains (grTLD) * sponsored top-level domains (sTLD) * country code top-level domains (ccTLD) * test top-level domains (tTLD) ...

Top-level Domain
A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet after the root domain. The top-level domain names are installed in the root zone of the name space. For all domains in lower levels, it is the last part of the domain name, that is, the last non empty label of a fully qualified domain name. For example, in the domain name www.example.com, the top-level domain is .com. Responsibility for management of most top-level domains is delegated to specific organizations by the ICANN, an Internet multi-stakeholder community, which operates the Internet Assigned Numbers Authority (IANA), and is in charge of maintaining the DNS root zone. History Originally, the top-level domain space was organized into three main groups: ''Countries'', ''Categories'', and ''Multiorganizations''. An additional ''temporary'' group consisted of only the initial DNS domain, arpa, and was intended for transitional purposes toward the ...

Second-level Domain
In the Domain Name System (DNS) hierarchy, a second-level domain (SLD or 2LD) is a domain that is directly below a top-level domain (TLD). For example, in , is the second-level domain of the TLD. Second-level domains commonly refer to the organization that registered the domain name with a domain name registrar. Some domain name registries introduce a second-level hierarchy to a TLD that indicates the type of entity intended to register an SLD under it. For example, in the .uk namespace a college or other academic institution would register under the ccSLD, while companies would register under . Strictly speaking, domains like .ac.uk and .co.uk are second level domain themselves, since they are right below a TLD. A list of the official TLDs can be found at icann.org and iana.org. An ordinal-free term to denote domains under which people can register their own domain name is public suffix domain (PSD). Country-code second-level domains Algeria Australia Austria In ...

Nationally Recognized Accrediting Agencies In The United States
Higher education accreditation in the United States is a peer review process by which the validity of degrees and credits awarded by higher education institutions is assured. It is coordinated by accreditation commissions made up of member institutions. It was first undertaken in the late 19th century by cooperating educational institutions, on a regional basis. The federal government began to play a limited role in higher education accreditation in 1952 with reauthorization of the G.I. Bill for Korean War veterans. The original GI Bill legislation had stimulated establishment of new colleges and universities to accommodate the influx of new students; but some of these new institutions were of dubious quality. The 1952 legislation designated the existing peer review process as the basis for measuring institutional quality; GI Bill eligibility was limited to students enrolled at accredited institutions included on a list of federally recognized accredited institutions published ...
