WED DESIGNING
The client/server programs can be divided into two categories: those that can be directly used by the user, such as e-mail, and those that support other application programs. The Domain Name system (DNS) is a supporting program that is used by other programs such as e-mail.
People prefer to use names instead of numeric addresses. Therefore, we need a system that can map a name to an address vice versa. To identify an entity, TCP/IP protocols use the IP address, which uniquely identifies the connection of a host to the internet.
Name space is a unique name assigned to a machine.
TWO TYPES
Flart and Hierarchy name space.
(1) Fully Qualified Domain Name (FDDN). An FDDN is a domain name that contains the full name of a host. It contains all the label from the most specific to the root in a domain tree. ADNS server can only match an FDDN to an address.
(2) Partially Qualified Domain Name (PDDN) starts from a node, but it does not reach the root. It is used when the name to be resolved belong to the same site as the client.
