Afs

AFS is an acronym that can refer to several distinct entities and technologies. The two most common references are Andrew File System (AFS), a distributed networked file system, and AFS Intercultural Programs, a nonprofit organization promoting intercultural exchange. The acronym is used by other groups and systems in various fields, depending on context.

Andrew File System: Developed at Carnegie Mellon University in the 1980s, AFS is a scalable distributed file system designed to provide location-transparent access to files across a wide area. It uses client-side caching, a virtual file system, and a cell-based administrative model to support security and administration across organizational boundaries. Authentication is typically handled through Kerberos within a cell. The system employs volume management and a server architecture that allows data to be served from multiple volumes, with replication and cache consistency managed to optimize performance and reliability. OpenAFS is a widely used open-source implementation that continues the legacy of the original system. While many organizations have migrated to other storage solutions, AFS remains in use in some universities and legacy environments.

AFS Intercultural Programs: Formerly known as the American Field Service, AFS Intercultural Programs is an international nonprofit that promotes intercultural learning through student exchanges, volunteer activities, and other programs. Programs place participants with host families or in schools and community projects in dozens of countries, aiming to foster cross-cultural understanding. The organization relies on volunteers, host families, and partner institutions and has operated for several decades, adapting to changes in education travel and safety standards.

Other uses: Beyond these, AFS is used as an acronym by various organizations and technologies not described here; the intended meaning is usually clear from context.
