Domain Name System (Dns) (Computer Virus)

A hierarchical system of host naming that groups TCP/IP hosts into categories. For example, in the Internet naming scheme, names with .com extensions identify hosts in commercial businesses.

Domain Name System (Dns) (Domain Name Registration)

The Internet was built on the notion that any computer on a global network can be identified by its numeric Internet Protocol (IP) address. But since people, and not machines, are the primary users of the Internet, a more people-friendly naming system called the Domain Name System (DNS) was invented. DNS maps a host name like www.opensrs.org to the IP address of the machine that hosts the OpenSRS web site. For example, DNS actually maps the host name www.opensrs.com to the IP address 207.136.98.175 DNS is built upon the notion that some server's are 'authoritative' (meaning, knows all there is to know) for certain domains. A distributed name server hierarchy, beginning with the A Root Server and ending at the thousands of nameservers active on the Internet, ensures that the naming and directing system works the same from anywhere.

Domain Name System (Dns) (Domain Names)

A local database that translates domain names to Internet Protocol (IP) addresses. It is much easier for humans to remember and use names than IP numbers, which are what computers need to find each other on the Internet. Individual Internet computers around the globe maintain their specific portion of this database, and the data held in each portion of the database is made available to all computers and users on the Internet. The DNS comprises computers, data files, software, and people working together.

When you enter [www.topicalterminology.com] in your browser, the local DNS server finds a match and connects your to the site. Most people who access the internet from home use an Internet Service Provider (ISP). The ISP typically assigns Internet Protocol (IP) numbers dynamically to these users. That is, they have a different IP number each time they log on to the internet. This allows a provider to use a limited number of addresses for all of their users as the ISPs total subscriber base is never logged in at once.

To be able to register a domain name, your ISP must assign you a static IP number (one that never changes). This is usually an additional cost. Of course, you still need a computer system that will host your domain. Most ISPs offer domain hosting.

Domain Name System (Dns) (Internet)

An application layer protocol providing the naming capability on the Internet.

Domain Name System (Dns) (Linux, Red Hat)

A service database that translates an IP address into a domain name (like redhat.com).

Domain Name System (Dns) (Technology)

The DNS is a static, hierarchical name service used with TCP/IP hosts, and is housed on a number of servers on the Internet. Basically, a DNS server maintains a database for figuring out and finding (or resolving) host names and IP addresses on the Internet. This allows users to specify remote computers by host names rather than numerical IP addresses The advantage of the DNS is that you don't have to remember numerical IP addresses for all the Internet sites you want to access.

Domain Name System (Dns) (Web Hosting)

A model for tracking other machines (that contain web sites) and their numeric IP addresses. Translates domain names (for example, www.FindMyHosting.com into a numerical IP address such as 216.119.81.205). When a computer is referred to by name, a domain name server puts that name into the numeric IP address assigned to that computer. So when you buy a domain, say www.yourname.com, it does not become accessible until it gets assigned an IP address from a hosting company. Once the IP address is assigned, a cross-reference record (DNS record) is created that points your domain name to the numeric IP address.
