In this article i am going to share SharePoint 2019 Glossary Terms related to Administration Web Service Protocol. This would be very helpful to refer and informative.

• Absolute URL – The full Internet address of a page or other World Wide Web resource. The absolute URL includes a protocol, such as “http,” a network location, and an optional path and file name — for example, http://www.SharePointTechnicalSupport.com/.
• Configuration Database – A database that is stored on a back-end database server and contains both persisted objects and site collection metadata for lookup purposes.
• Endpoint – A communication port that is exposed by an application server for a specific shared service and to which messages can be addressed.
• Globally Unique Identifier (GUID) – A term used interchangeably with universally unique identifier (UUID) in Microsoft protocol technical documents (TDs).
• Hypertext Transfer Protocol (HTTP) – An application-level protocol for distributed, collaborative, hypermedia information systems (text, graphic images, sound, video, and other multimedia files) on the World Wide Web.
• Hypertext Transfer Protocol Secure (HTTPS) – An extension of HTTP that securely encrypts and decrypts web page requests. In some older protocols, “Hypertext Transfer Protocol over Secure Sockets Layer” is still used (Secure Sockets Layer has been deprecated).
• Language code identifier (LCID) – A 32-bit number that identifies the user interface human language dialect or variation that is supported by an application or a client computer.
• Portal Site – A type of SharePoint site that can act as an umbrella to other sites and can be used by a large organization.
• Request Message – A Traversal Using Relay NAT (TURN) message that is sent from a protocol client to a protocol server
• Response Message – A Traversal Using Relay NAT (TURN) message that is sent from a protocol server to a protocol client in response to a request message. It is sent when the request message is handled successfully by the protocol server.
• Site – A group of related pages and data within a SharePoint site collection. The structure and content of a site is based on a site definition. Also referred to as SharePoint site and web site.
• Site Collection – A set of websites that are in the same content database, have the same owner, and share administration settings. A site collection can be identified by a GUID or the URL of the top-level site for the site collection. Each site collection contains a top-level site, can contain one or more subsites, and can have a shared navigational structure.
• Site Definition – family of site definition configurations. Each site definition specifies a name and contains a list of associated site definition configurations.
• Site Template – An XML-based definition of site settings, including formatting, lists, views, and elements such as text, graphics, page layout, and styles. Site templates are stored in .stp files in the content database.
• SOAP – A lightweight protocol for exchanging structured information in a decentralized, distributed environment. SOAP uses XML technologies to define an extensible messaging framework, which provides a message construct that can be exchanged over a variety of underlying protocols. The framework has been designed to be independent of any particular programming model and other implementation-specific semantics. SOAP 1.2 supersedes SOAP 1.1.
• SOAP action – The HTTP request header field used to indicate the intent of the SOAP request, using a URI value.
• SOAP body – A container for the payload data being delivered by a SOAP message to its recipient.
• SOAP fault – A container for error and status information within a SOAP message.
• Status-Code – A 3-digit integer result code in an HTTP response message.
• Uniform Resource Locator (URL) – string of characters in a standardized format that identifies a document or resource on the World Wide Web.
• User Name – A unique name that identifies a specific user account. The user name of an account is unique among the other group names and user names within its own domain or workgroup.
• Web Application – A container in a configuration database that stores administrative settings and entry-point URLs for site collections
• Web Services Description Language (WSDL) – An XML format for describing network services as a set of endpoints that operate on messages that contain either document-oriented or procedure-oriented information. The operations and messages are described abstractly and are bound to a concrete network protocol and message format in order to define an endpoint. Related concrete endpoints are combined into abstract endpoints, which describe a network service. WSDL is extensible, which allows the description of endpoints and their messages regardless of the message formats or network protocols that are used.
• website – A group of related pages and data within a SharePoint site collection. The structure and content of a site is based on a site definition. Also referred to as SharePoint site and site.
• WSDL operation – A single action or function of a web service. The execution of a WSDL operation typically requires the exchange of messages between the service requestor and the service provider.
• XML namespace – A collection of names that is used to identify elements, types, and attributes in XML documents identified in a URI reference [RFC3986]. A combination of XML namespace and local name allows XML documents to use elements, types, and attributes that have the same names but come from different sources.
• XML schema – A description of a type of XML document that is typically expressed in terms of constraints on the structure and content of documents of that type, in addition to the basic syntax constraints that are imposed by XML itself. An XML schema provides a view of a document type at a relatively high level of abstraction.
