- application-level naming service
Application-level naming services are incorporated in applications offering services such as files, mail,
and printing. Application-level naming services are bound below enterprise-level naming services. The enterprise-level naming
services provide contexts in which contexts of application-level naming services can be bound.
Each LDAP entry consists of a number of named attributes each of
which has one or more values.
Also, the N2L service mapping and configuration files each consist of a number of
named attributes. Each attribute has one or more values.

from an naming server.
(2) In the client-server model for file systems, the client is a machine that
remotely accesses resources of a compute server, such as compute power and large
(3) In the client-server model, the client is an application that accesses services from
a “server process.” In this model, the client and the server can run
on the same machine or on separate machines.
