Answer 2

The term domain name has multiple related meanings:

# A name that identifies a computer or computers on the internet. These names appear as a component of a Web site's URL, e.g. www.sitename.com. This type of domain name is also called a hostname.
# The product that Domain name registrars provide to their customers. These names are often called registered domain names.
# Names used for other purposes in the Domain Name System (DNS), for example the special name which follows the @ sign in an email address, or the Top-level domains like .com, or the names used by the Session Initiation Protocol (VoIP), or DomainKeys.

Answer 3

The most common types of domain names are hostnames that provide more memorable names to stand in for numeric IP addresses. They allow for any service to move to a different location in the topology of the Internet (or an intranet), which would then have a different IP address.

By allowing the use of unique alphabetical addresses instead of numeric ones, domain names allow Internet users to more easily find and communicate with web sites and other server-based services. The flexibility of the domain name system allows multiple IP addresses to be assigned to a single domain name, or multiple domain names to be assigned to a single IP address. This means that one server may have multiple roles (such as hosting multiple independent Web sites), or that one role can be spread among many servers. One IP address can also be assigned to several servers, as used in anycast and hijacked IP space.

Hostnames are restricted to the ASCII letters "a" through "z' (case-insensitive), the digits "0" through "9", and the hyphen, with some other restrictions. Registrars restrict the domains to valid hostnames, since, otherwise, they would be useless. The Internationalized domain name (IDN) system has been developed to bypass the restrictions on character allowances in hostnames, making it easier for non-english alphabets to use the Internet. The underscore character is frequently used to ensure that a domain name is not recognized as a hostname, for example with the use of SRV records, although some older systems, such as Netbios did allow it. Due to confusion and other reasons, domain names with underscores in them are sometimes used where hostnames are required.

Answer 4

All people above have provided great answers but still if you haven't understood then in simple language the domain name is the name which identifies one or more I.P. addresses.

If you don't know what I.P. addresses are then maybe you will again have to ask one question similar to this one that what is I.P. address. Or you can search for it in yahoo search engine for find some results related to it.

Answer 5

Acutally in web page. the servers are represented in number formats only. like 172.16.5.200(for example). So we can forget it quickly. In general we give the name for each website in common speaking language(like english). And seperate the name into three pars. www or ftp (as a root name) yahoo or google ( as a server name) .com or org (As a domain name). Thats it.

Answer 6
