The Domain Name System ( DNS) is a hierarchical and distributed name service that provides a naming system for computers, services, and other resources in the Internet or other Internet Protocol (IP) networks. It associates various information with domain names (identification strings) assigned to each of the associated entities.
Name server. A name server is a computer application that implements a network service for providing responses to queries against a directory service. It translates an often humanly meaningful, text-based identifier to a system-internal, often numeric identification or addressing component. This service is performed by the server in response to ...
Namespace. In computing, a namespace is a set of signs ( names) that are used to identify and refer to objects of various kinds. A namespace ensures that all of a given set of objects have unique names so that they can be easily identified . Namespaces are commonly structured as hierarchies to allow reuse of names in different contexts.
Netty is a non-blocking I/O client-server framework for the development of Java network applications such as protocol servers and clients. The asynchronous event-driven network application framework and tools are used to simplify network programming such as TCP and UDP socket servers. [2] Netty includes an implementation of the reactor pattern ...
A directory server or name server is a server which provides such a service. Each resource on the network is considered an object by the directory server. Information about a particular resource is stored as a collection of attributes associated with that resource or object. A directory service defines a namespace for the network.
The Java Naming and Directory Interface ( JNDI) is a Java API for a directory service that allows Java software clients to discover and look up data and resources (in the form of Java objects) via a name. Like all Java APIs that interface with host systems, JNDI is independent of the underlying implementation.
In the Internet, a hostname is a domain name assigned to a host computer. This is usually a combination of the host's local name with its parent domain's name. For example, en.wikipedia.org consists of a local hostname ( en) and the domain name wikipedia.org. This kind of hostname is translated into an IP address via the local hosts file, or ...
Apache Hadoop ( / həˈduːp /) is a collection of open-source software utilities that facilitates using a network of many computers to solve problems involving massive amounts of data and computation. [vague] It provides a software framework for distributed storage and processing of big data using the MapReduce programming model.
