Adobe Flash is a multimedia software platform used for production of animations, rich web applications, desktop applications, mobile apps, mobile games, and embedded web browser video players. Flash displays text, vector graphics, and raster graphics to provide animations, video games, and applications. It allowed streaming of audio and video, and can capture mouse, keyboard, microphone, and camera input.

FileZilla is a free and open-source, cross-platform FTP application, consisting of FileZilla Client and FileZilla Server. Client binaries are available for Windows, Linux, and macOS, server binaries are available for Windows only. Both server and client support FTP and FTPS, while the client can in addition connect to SFTP servers.
The Public Utility Regulatory Policies Act is a United States Act passed as part of the National Energy Act. It was meant to promote energy conservation and promote greater use of domestic energy and renewable energy. The law was created in response to the 1973 energy crisis, and one year in advance of a second energy crisis.

Hierarchical storage management (HSM) is a data storage technique that automatically moves data between high-cost and low-cost storage media. HSM systems exist because high-speed storage devices, such as solid state drive arrays, are more expensive than slower devices, such as hard disk drives, optical discs and magnetic tape drives. While it would be ideal to have all data available on high-speed devices all the time, this is prohibitively expensive for many organizations. Instead, HSM systems store the bulk of the enterprise's data on slower devices, and then copy data to faster disk drives when needed. In effect, HSM turns the fast disk drives into caches for the slower mass storage devices. The HSM system monitors the way data is used and makes best guesses as to which data can safely be moved to slower devices and which data should stay on the fast devices.
The Oracle Cluster File System is a shared disk file system developed by Oracle Corporation and released under the GNU General Public License. The first version of OCFS was developed with the main focus to accommodate Oracle's database management system that used cluster computing. Because of that it was not a POSIX-compliant file system. With version 2 the POSIX features were included.
QFS is a filesystem from Oracle. It is tightly integrated with SAM, the Storage and Archive Manager, and hence is often referred to as SAM-QFS. SAM provides the functionality of a hierarchical storage manager.
A clustered file system is a file system which is shared by being simultaneously mounted on multiple servers. There are several approaches to clustering, most of which do not employ a clustered file system. Clustered file systems can provide features like location-independent addressing and redundancy which improve reliability or reduce the complexity of the other parts of the cluster. Parallel file systems are a type of clustered file system that spread data across multiple storage nodes, usually for redundancy or performance.
In computing, a distributed file system (DFS) or network file system is any file system that allows access to files from multiple hosts sharing via a computer network. This makes it possible for multiple users on multiple machines to share files and storage resources.
Quantcast File System (QFS) is an open-source distributed file system software package for large-scale MapReduce or other batch-processing workloads. It was designed as an alternative to the Apache Hadoop Distributed File System (HDFS), intended to deliver better performance and cost-efficiency for large-scale processing clusters.
The HD Pentax-D FA* 70–200mm f/2.8 ED DC AW lens is a professional telephoto zoom lens for the Pentax K-mount. Announced jointly with the HD PENTAX-D FA 150-450mm F4.5-5.6ED DC AW in February 2015, it is one a pair of full-frame lenses to reboot Pentax' involvement in that format, the last previously introduced full-frame lens being the D FA 100mm weather-sealed macro lens in 2009. On Pentax APS-C cameras, the D FA* 70–200mm has an equivalent focal length range of 107–307mm.
