A directory is often described as a database, but it is a specialized database that has characteristics that set it apart from general-purpose relational databases. One special characteristic of directories is that they are accessed (read or searched) much more often than they are updated (written). Hundreds of people might look up an individual's phone number, or thousands of print clients might look up the characteristics of a particular printer, but the phone number or printer characteristics rarely change.

LDAPis therfore a sibling protocol to HTTP and FTP and uses the 'ldap://' prefix in its URL (like http:// or ftp://).Answer:LDAP is a client-server protocol for accessing a directory service. It was initially used as a front-end to X.500, but can also be used with stand-alone and other kinds of directory servers.
