  • directory service — (database, networking)   A structured repository of information on people and resources within an organisation, facilitating management and communication. On a LAN or WAN the directory service identifies all aspects of the network including users, software, hardware, and the various rights and policies assigned to each. As a result applications can access information without knowing where a particular resource is physically located, and users interact oblivious to the network topology and protocols. To allow heterogeneous networks to share directory information the ITU proposed a common structure called X.500. However, its complexity and lack of seamless Internet support led to the development of Lightweight Directory Access Protocol (LDAP) which has continued to evolve under the aegis of the IETF. Despite its name LDAP is too closely linked to X.500 to be "lightweight".

  • disaster recovery — (business)   (DR) Planning and implementation of procedures and facilities for use when essential systems are not available for a period long enough to have a significant impact on the business, e.g. when the head office is blown up.

Companies need to plan for disaster: before: risk analysis, preventive measures, training; during: how should staff and systems respond; after: recovery measures, post mortem analysis. Hardware can usually be replaced and is usually insured. Software and data needs to be backed up off site. Alternative communication systems should be arranged in case of network failure or inaccessible premises, e.g. emergency telephone number, home working, alternative data center.
