Example: SQL Queries; Location transparency – Users of a distributed system should not have to be aware of where a resource is physically located. Example: Pages in the Web; Migration transparency – Users should not be aware of whether a resource or computing entity possesses the ability to move to a different physical or logical location ...
In computer networks, location transparency is the use of names to identify network resources, rather than their actual location. [1] [2] For example, files are accessed by a unique file name, but the actual data is stored in physical sectors scattered around a disk in either the local computer or in a network. In a location transparency system ...
This kind of transparency is referred to as network transparency or distribution transparency. From a database management system (DBMS) perspective, distribution transparency requires that users do not have to specify where data is located. Some have separated distribution transparency into location transparency and naming transparency.
Transparency or single-system image refers to the ability of an application to treat the system on which it operates without regard to whether it is distributed and without regard to hardware or other implementation details. Many areas of a system can benefit from transparency, including access, location, performance, naming, and migration.
Distributed file systems may aim for "transparency" in a number of aspects. That is, they aim to be "invisible" to client programs, which "see" a system which is similar to a local file system. Behind the scenes, the distributed file system handles locating files, transporting data, and potentially providing other features listed below.
Distributed File System (DFS) is a set of client and server services that allow an organization using Microsoft Windows servers to organize many distributed SMB file shares into a distributed file system. DFS has two components to its service: Location transparency (via the namespace component) and Redundancy (via the file replication component).

Failure transparency is one of the most difficult types of transparency to achieve since it is often difficult to determine whether a server has actually failed, or whether it is simply responding very slowly. [1] Additionally, it is generally impossible to achieve full failure transparency in a distributed system since networks are unreliable.
