Apple File System was announced at Apple's developers’ conference (WWDC) in June 2016 as a replacement for HFS+, which had been in use since 1998. [11] [12] APFS was released for 64-bit iOS devices on March 27, 2017, with the release of iOS 10.3, and for macOS devices on September 25, 2017, with the release of macOS 10.13.
HyperCard is based on the concept of a "stack" of virtual "cards". [6] Cards hold data, just as they would in a Rolodex card-filing device. Each card contains a set of interactive objects, including text fields, check boxes, buttons, and similar common graphical user interface (GUI) elements.
Fusion Drive is a block-level solution based on Apple's Core Storage, a logical volume manager managing multiple physical devices. [6] [7] The capacity of a Fusion Drive is confirmed to be the sum of two devices. [6] [7] Fusion Drive is file system agnostic and effective for both HFS Plus and ZFS. [8]
To the consumer, the capabilities available for provisioning often appear unlimited and can be appropriated in any quantity at any time." Measured service: "Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing ...
Several methods have been proposed for producing computing devices or data storage devices that approach physical and practical limits: A cold degenerate star could conceivably be used as a giant data storage device, by carefully perturbing it to various excited states, in the same manner as an atom or quantum well used for these purposes. Such ...
Storage capacity can refer to Thermal electric capacity mostly referring to solar power plants; Energy storage capacity; Depression storage capacity, in soil science; Computer data storage capacity, in computing Native capacity, the apparent storage capacity may differ due to compression
Historically, MAC was strongly associated with multilevel security (MLS) as a means of protecting classified information of the United States.The Trusted Computer System Evaluation Criteria (TCSEC), the seminal work on the subject and often known as the Orange Book, provided the original definition of MAC as "a means of restricting access to objects based on the sensitivity (as represented by ...
