Apple File System
Apple File System (APFS) is a Proprietary software, proprietary file system developed and deployed by Apple Inc. for macOS macOS Sierra, Sierra (10.12.4) and later, iOS iOS 10 , 10.3, tvOS 10.2, watchOS 3.2, and all versions of iPadOS. It aims to fix HFS Plus#Criticisms, core problems of HFS Plus, HFS+ (also called Mac OS Extended), APFS's predecessor which had been in use since 1998. APFS is optimized for solid-state drive storage and supports encryption, Snapshot_(computer_storage) , snapshots, and improved handling of file system#metadata, metadata integrity. History Apple File System was announced at Apple Inc., Apple's Apple Worldwide Developers Conference, developers’ conference (WWDC) in June 2016 as a replacement for HFS Plus, HFS+, which had been in use since 1998.

Apple Filing Protocol
The Apple Filing Protocol (AFP), formerly AppleTalk Filing Protocol, is a proprietary protocol, proprietary Communications protocol, network protocol, and part of the Apple File Service (AFS), that offers file services for macOS, classic Mac OS, and Apple II computers. In OS X Mountain Lion, OS X 10.8 Mountain Lion and earlier, AFP was the primary protocol for file services. Starting with OS X Mavericks, OS X 10.9 Mavericks, Server Message Block (SMB) was made the primary file sharing protocol, with the ability to run an AFP server removed later in macOS Big Sur, macOS 11 Big Sur and the client being marked for deprecation in the 15.5 update of macOS Sequoia, MacOS Sequoia. AFP supports Unicode file names, POSIX and access-control list permissions, resource forks, named extended attributes, and advanced file locking. Compatibility AFP versions 3.0 and greater rely exclusively on Internet protocol suite, TCP/IP (port 548) for establishing communication, supporting AppleTalk only a ...

MacOS High Sierra
macOS High Sierra (version 10.13) is the fourteenth major release of macOS, Apple Inc.'s desktop operating system for Macintosh computers. macOS High Sierra was announced at the WWDC 2017 on June 5, 2017 and was released on September 25, 2017. The name "High Sierra" refers to the High Sierra region in California. Its name signified its goal to be a refinement of the previous macOS version, macOS Sierra, focused on performance improvements and technical updates rather than features. This makes it similar to previous macOS releases Snow Leopard, Mountain Lion and El Capitan. Among the apps with notable changes are Photos and Safari. macOS High Sierra is the final version of macOS to support the Unibody iMac and the Polycarbonate Unibody MacBook, as its successor, macOS Mojave, drops support for the late 2009 and final models. System requirements All Macs that supported macOS Sierra support macOS High Sierra. *iMac (Late 2009 or later) * MacBook (Late 2009 or later) *MacBo ...

64-bit Computing
In computer architecture, 64-bit integers, memory addresses, or other data units are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, address buses, or data buses of that size. A computer that uses such a processor is a 64-bit computer. From the software perspective, 64-bit computing means the use of machine code with 64-bit virtual memory addresses. However, not all 64-bit instruction sets support full 64-bit virtual memory addresses; x86-64 and AArch64, for example, support only 48 bits of virtual address, with the remaining 16 bits of the virtual address required to be all zeros (000...) or all ones (111...), and several 64-bit instruction sets support fewer than 64 bits of physical memory address. The term ''64-bit'' also describes a generation of computers in which 64-bit processors are the norm. 64 bits is a Word (computer architecture), word size that defines ...

Apple Worldwide Developers Conference
The Worldwide Developers Conference (WWDC) is an information technology conference held annually by Apple Inc. The conference is currently held at Apple Park in California. The event is used to showcase new software and technologies in the macOS, iOS, iPadOS, watchOS, tvOS, and visionOS families as well as other Apple software; new hardware products are sometimes announced as well. WWDC is also an event hosted for third-party software developers that work on apps for iPhones, iPads, Mac (computer), Macs, and other List of Apple products, Apple devices. Attendees can participate in hands-on labs with Apple engineers and attend in-depth sessions covering a wide variety of topics. The first WWDC was held in 1983, with the introduction of Apple Basic, but it was not until 2002 that Apple started using the conference as a major launchpad for new products. Beginning in 1987, WWDC was held in Santa Clara, California, Santa Clara. After 15 years in nearby San Jose, the conference moved ...

Snapshot (computer Storage)
In computer systems, a snapshot is the state of a system at a particular point in time. The term was coined as an analogy to that in photography. Rationale A full backup of a large data set may take a long time to complete. On multi-tasking or multi-user systems, there may be writes to that data while it is being backed up. This prevents the backup from being atomic and introduces a version skew that may result in data corruption. For example, if a user moves a file into a directory that has already been backed up, then that file would be completely missing on the backup media, since the backup operation had already taken place before the addition of the file. Version skew may also cause corruption with files which change their size or contents underfoot while being read. One approach to safely backing up live data is to temporarily disable write access to data during the backup, either by stopping the accessing applications or by using the locking API provided by the ope ...

Encryption
In Cryptography law, cryptography, encryption (more specifically, Code, encoding) is the process of transforming information in a way that, ideally, only authorized parties can decode. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Despite its goal, encryption does not itself prevent interference but denies the intelligible content to a would-be interceptor. For technical reasons, an encryption scheme usually uses a pseudo-random encryption Key (cryptography), key generated by an algorithm. It is possible to decrypt the message without possessing the key but, for a well-designed encryption scheme, considerable computational resources and skills are required. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients but not to unauthorized users. Historically, various forms of encryption have been used to aid in cryptography. Early encryption ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Solid-state Drive
A solid-state drive (SSD) is a type of solid-state storage device that uses integrated circuits to store data persistently. It is sometimes called semiconductor storage device, solid-state device, or solid-state disk. SSDs rely on non-volatile memory, typically NAND flash, to store data in memory cells. The performance and endurance of SSDs vary depending on the number of bits stored per cell, ranging from high-performing single-level cells (SLC) to more affordable but slower quad-level cells (QLC). In addition to flash-based SSDs, other technologies such as 3D XPoint offer faster speeds and higher endurance through different data storage mechanisms. Unlike traditional hard disk drives (HDDs), SSDs have no moving parts, allowing them to deliver faster data access speeds, reduced latency, increased resistance to physical shock, lower power consumption, and silent operation. Often interfaced to a system in the same way as HDDs, SSDs are used in a variety of devices, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
