What does Shared Hosting mean?

-

Shared Hosting (or Shared Web Hosting) is a term in the Internet Hosting industry which refers to a number or Virtual Hosting accounts and websites hosted on one physical or virtual instance (server). Each virtual account has its own partition on the server in order to be separated from others. All those hosting accounts share the resources (processor, memory, bandwidth, software) of the underlying server. It can host thousands of websites.

Shared Hosting services is either name-based or IP-based. In IP-based virtual hosting each Shared account uses a dedicated IP address. The host server is configured with multiple physical network interfaces, or virtual network interfaces on the same physical interface. In name-based virtual hosting all Shared accounts on the server share a single IP address. In name-based hosting Web browsers request a resource from the web server of the host server using HTTP/1.1 which includes a certain hostname as part of the request. The host server uses this information to determine which web site to show the visitor.

Please note that term “Virtual Hosting” has nothing to do with “Virtual Private Server Hosting” (VPS, VPS Hosting, Virtual Servers ).

What does Name Server mean?

-

Name server (nameserver) is combination of software program and hardware device which implements a name-service protocol. It maps a human-recognizable domain names to a system-internal, numeric identification.

The most widely used types of name servers are those of the Domain Name System (DNS). The most important function of the DNS servers is to translate (resolve) of domain names and hostnames into Internet Protocol (IP) addresses, which are the second principal Internet name space, used to identify and locate network device, server or computer on the Internet.

What does Domain Name System mean?

-

The Domain Name System is an Internet naming system that makes it possible to assign domain names to groups of Internet resources and users, independent of each entity’s physical location. Domain names are easier to remember than IP addresses such as 207.75.188.166 (IPv4) or 2001:db6:1f70::999:de8:7648:6e8 (IPv6). Internet users use domain names to recite meaningful Uniform Resource Locators (URLs) and e-mail addresses.

The Domain Name System distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating name servers for each domain. Name servers are responsible for their particular domains. The are DNS distributed and fault tolerant. This makes possible for the WWW to avoid keeping everything in a single central register which has to be continually consulted and updated.

Domain Name System also stores information about the list of mail servers that accept email for web addresses. Domain Name System is a very important component of the Internet as we know it because it provides a distributed keyword-based redirection service.

What does a Domain Name mean?

-

Domain Names are web addresses, identification labels which defines an administrative autonomy, authority, or control in the Internet.

A Domain name is also hostname which identifies Internet Protocol (IP) resources such as web sites. Domain names are formed by the rules and procedures of the Domain Name System (DNS). They are used in various networking contexts and application-specific naming and addressing purposes. Domains are organized in subordinate levels (subdomains) of the DNS root domain, which is nameless.

The first-level set of domain names are the Top-level domains (TLDs), including the generic top-level domains (gTLDs), such as .COM, .NET and .ORG, and the country code Top-level domains (ccTLDs).

There are second-level and third-level domain names in the DNS hierarchy which are open for reservation by end-users as well.
