Define Domain In Computer Science
The domain name system dns is a hierarchical decentralized naming system for computers services or other resources connected to the internet or a private network.
Define domain in computer science. So the domain in computer science is a uniquethe combination of symbols of the latin alphabet which allows you to find a specific site among a huge number of others. Domain theory formalizes the intuitive ideas of approximation and convergence in a very general way and is closely related to topology. A domain is a network of computers and devices that are controlled by one set authority and that have specific guidelines. Consequently domain theory can be considered as a branch of order theory.
He is the visiting card of the company determines the activity of the site and also tells the visitor about the resource. For example a company may require all local computers to be networked within the same domain so that each computer can be seen from other computers within the domain or located from a central server. It associates various information with domain names assigned to each of the participating entities. A domain in the context of networking refers to any group of users workstations devices printers computers and database servers that share different types of data via network resources.
It is used to divide global areas or departments of a corporation. A domain may need to be specified when mapping a network computer or drive. Setting up a domain may also block outside traffic from accessing computers within the network which adds an extra level of security. More specifically within the internet a domain is controlled by one particular company that has its own internet presence and ip address.
A domain has a domain controller that governs all basic domain functions and manages network security. When referring to a computer network a domain is a group of resources assigned to a specific group of individuals. There are also many types of subdomains. The field has major applications in computer science where it is used to specify denotational semantics especially for functional programming languages.
