NetBoot
NetBoot was a technology from Apple which enabled Macs with capable firmware (i.e. New World ROM) to boot from a network, rather than a local hard disk or optical disc drive. NetBoot is a derived work from the Bootstrap Protocol (BOOTP), and is similar in concept to the Preboot Execution Environment. The technology was announced as a part of the original version of Mac OS X Server at Macworld Expo on 5 January 1999. NetBoot has continued to be a core systems management technology for Apple, and has been adapted to support modern Mac Intel machines. NetBoot, USB, and FireWire are some of the external volume options for operating system re-install. NetBoot is not supported on newer Macs with T2 security chip or Apple silicon. Process A disk image with a copy of macOS, macOS Server, Mac OS 9, or Mac OS 8 is created using System Image Utility and is stored on a server, typically macOS Server. Clients receive this image across a network using many popular protocols includi ...

Preboot Execution Environment
In computing, the Preboot eXecution Environment, PXE (most often pronounced as ''pixie'', often called PXE Boot/''pixie boot''.) specification describes a standardized client–server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients. On the client side it requires only a PXE-capable network interface controller (NIC), and uses a small set of industry-standard network protocols such as DHCP and TFTP. The concept behind the PXE originated in the early days of protocols like BOOTP/DHCP/TFTP, and it forms part of the Unified Extensible Firmware Interface (UEFI) standard. In modern data centers, PXE is the most frequent choice for operating system booting, installation and deployment. Overview Since the beginning of computer networks, there has been a persistent need for client systems which can boot appropriate software images, with appropriate configuration parameters, both retrieved at boot time from one or more network servers. T ...

MacOS Server
macOS Server, formerly Mac OS X Server and OS X Server, is a discontinued series of Unix-like server operating systems developed by Apple Inc., based on macOS and later add-on software packages for the latter. macOS Server added server functionality and system administration tools to macOS and provided tools to manage both macOS-based computers and iOS-based devices. Versions of Mac OS X Server prior to version 10.7 “Lion” were sold as complete, standalone server operating systems; starting with Mac OS X 10.7 “Lion,” Mac OS X Server (and its successors OS X Server and macOS Server) have been offered as add-on software packages, sold through the Mac App Store, that are installed on top of a corresponding macOS installation. macOS Server at one point provided network services such as a mail transfer agent, AFP and SMB servers, an LDAP server, and a domain name server, as well as server applications including a Web server, database, and c ...

Macworld Conference & Expo
Macworld/iWorld was an information technology trade show with conference tracks dedicated to the Apple Macintosh platform. It was held annually in the United States during January. Originally ''Macworld Expo'' and then ''Macworld Conference & Exposition'', the gathering dates back to 1985. The conference was organized by International Data Group (IDG), co-publisher of ''Macworld'' magazine. On December 18, 2008, Apple announced that the 2009 Macworld Conference & Expo would be the last in which the company participates. On October 14, 2014, IDG suspended Macworld/iWorld indefinitely. History The first Macworld Expo occurred in 1985 in San Francisco. The conference itself was created by Peggy Kilburn, who helped to increase the size and profit of the event during her tenure (1985–1999). Among the speakers recruited by Kilburn were David Pogue, Steve Case, Bob LeVitus, as well as representatives from BMUG, LaserBoard, and other major user groups. Participation by Apple was us ...

Dynamic Host Configuration Protocol
The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client–server architecture. The technology eliminates the need for individually configuring network devices manually, and consists of two network components, a centrally installed network DHCP server and client instances of the protocol stack on each computer or device. When connected to the network, and periodically thereafter, a client requests a set of parameters from the server using DHCP. DHCP can be implemented on networks ranging in size from residential networks to large campus networks and regional ISP networks. Many routers and residential gateways have DHCP server capability. Most residential network routers receive a unique IP address within the ISP network. Within a local network, a DHCP server assigns a local IP address to ...

Apple T2
The Apple T2 (Apple's internal name is T8012) security chip is a system on a chip "SoC" tasked with providing security and controller features to Apple's Intel based Macintosh computers. It is a 64-bit ARMv8 chip and runs bridgeOS. T2 has its own RAM and is essentially a computer of its own, running in parallel to and responding to requests by the main computer that the user interacts with. Design The main application processor in T2 is a variant of the Apple A10, which is a 64-bit ARMv8.1-A based CPU. It is manufactured by TSMC on their 16 nm process, just as the A10. Analysis of the die reveals a nearly identical CPU macro as the A10 which reveals a four core design for its main application processor, with two large high performance cores, "Hurricane", and two smaller efficiency cores, "Zephyr". Analysis also reveals the same amount of RAM controllers, but a much reduced GPU facility; three blocks, only a quarter the size compared to A10. The die measures 9.6 × 10. ...

Ghost (software)
Ghost (an acronym for ''general hardware-oriented system transfer'') is a disk cloning and backup tool originally developed by Murray Haszard in 1995 for Binary Research. The technology was acquired in 1998 by Symantec. The backup and recovery functionality has been replaced by Symantec System Recovery (SSR), although the Ghost imaging technology is still actively developed and is available as part of Symantec Ghost Solution Suite. History Binary Research developed Ghost in Auckland, New Zealand. After the Symantec acquisition, a few functions (such as translation into other languages) were moved elsewhere, but the main development remained in Auckland until October 2009 at which time much was moved to India. Technologies developed by 20/20 Software were integrated into Ghost after their acquisition by Symantec in April 2000. Ghost 3.1 The first versions of Ghost supported only the cloning of entire disks. However, version 3.1, released in 1997 supports cloning individ ...

Software Deployment
Software deployment is all of the activities that make a software system available for use. The general deployment process consists of several interrelated activities with possible transitions between them. These activities can occur on the Software developer, producer side or on the User (computing), consumer side or both. Because every software system is unique, the precise Process (computing), processes or Algorithm, procedures within each activity can hardly be defined. Therefore, "deployment" should be interpreted as a ''general process'' that has to be customized according to specific requirements or characteristics. History When computers were extremely large, expensive, and bulky (mainframe computer, mainframes and minicomputers), the software was often bundled together with the hardware by manufacturers. If business software needed to be installed on an existing computer, this might require an expensive, time-consuming visit by a systems architect or a consultant. ...

Apple Software Restore
Apple Software Restore or asr is a command line utility in Mac OS X used to apply a DMG disk image to a selected partition or mount point on a file system. It is often used for cloning large numbers of Macintosh computers. Apple Software Restore can read an image locally or from a server via HTTP or its own multicast asr:// URI. asr has two methods it can use to restore an image to a volume: it can either copy items in a file-by-file mode, or it can directly block-copy the image. As the latter method does not need to go through the OS filesystem, it is much faster, typically being limited only by the speed of the drives or network connections involved. But in order to use this faster method the .dmg file involved must first be checksummed, and in some cases the files re-ordered inside the image. This is also done by the same tool. The graphical Disk Utility uses asr processes in the background to perform restores. See also * Disk cloning * List of disk cloning software A ''list ...

Multicast
In computer networking, multicast is group communication where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution. Multicast should not be confused with physical layer point-to-multipoint communication. Group communication may either be application layer multicast or network-assisted multicast, where the latter makes it possible for the source to efficiently send to the group in a single transmission. Copies are automatically created in other network elements, such as routers, switches and cellular network base stations, but only to network segments that currently contain members of the group. Network assisted multicast may be implemented at the data link layer using one-to-many addressing and switching such as Ethernet multicast addressing, Asynchronous Transfer Mode (ATM), point-to-multipoint virtual circuits (P2MP) or InfiniBand multicast. Network-assisted multicast may also be impl ...

Network File System (protocol)
Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems (Sun) in 1984, allowing a user on a client computer to access files over a computer network much like local storage is accessed. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC) system. NFS is an open IETF standard defined in a Request for Comments (RFC), allowing anyone to implement the protocol. Versions and variations Sun used version 1 only for in-house experimental purposes. When the development team added substantial changes to NFS version 1 and released it outside of Sun, they decided to release the new version as v2, so that version interoperation and RPC version fallback could be tested. NFSv2 Version 2 of the protocol (defined in RFC 1094, March 1989) originally operated only over User Datagram Protocol (UDP). Its designers meant to keep the server side stateless, with locking (for example) i ...
