The DDS (Doctor of Dental Surgery) and DMD (Doctor of Dental Medicine) are the same degrees. At least one of these degrees is required to become a general dentist. The majority of dental schools award the DDS degree, but some award a DMD degree. The level of education and the degrees are the same.
An intranet is a network based on TCP/IP protocols (an internet) belonging to an organization, usually a corporation, accessible only by the organization's members, employees, or others with authorization.
In its simplest form an intranet is established with the technologies for local area networks (LANs) and wide area networks (WANs). Intranets began to appear in a range of larger organizations from 1994.
