Sleep Proxy Service
Apple's Bonjour Sleep Proxy service is an open source component of zero-configuration networking, designed to assist in reducing power consumption of networked electronic devices. A device acting as a sleep proxy server will respond to Multicast DNS queries for another compatible device which has gone into low power mode. The ''low-power-mode'' device remains ''asleep'' while the sleep proxy server responds to Multicast DNS queries. When the sleep proxy server sees a query which requires the ''low-power-mode'' device to ''wake up'', the sleep proxy server sends a special wake-up-packet ("magic packet") to the low-power-mode device. Finally, communication parameters are updated via Multicast DNS, and normal communications proceed. Apple refers to the service as Bonjour Sleep Proxy in its support documents. The service supports the Wake on Demand feature, first offered in Mac OS X Snow Leopard. Details Address resolution protocol The sleep proxy service responds to addre ...

Worldwide Developers Conference
The Worldwide Developers Conference (WWDC) is an information technology conference held annually by Apple Inc. The conference is usually held at Apple Park in California. The event is usually used to showcase new software and technologies in the macOS, iOS, iPadOS, watchOS, and tvOS families as well as other Apple software. WWDC is also an event hosted for third-party software developers that work on apps for iPhones, iPads, Macs, and other 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 ever 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. After 15 years in nearby San Jose, the conference moved to San Francisco, where it eventually became Apple's primary media event of the year and regularly sold out. WWDC ret ...

Internet Sharing
Internet Connection Sharing (ICS) is a Windows service that enables one Internet-connected computer to share its Internet connection with other computers on a local area network (LAN). The computer that shares its Internet connection serves as a gateway device, meaning that all traffic between other computers and the Internet go through this computer. ICS provides Dynamic Host Configuration Protocol (DHCP) and network address translation (NAT) services for the LAN computers. ICS was a feature of Windows 98 SE and all versions of Windows released for personal computers thereafter. Operation ICS routes TCP/IP packets from a small LAN to the Internet. ICS provides NAT services, mapping individual IP addresses of local computers to unused port numbers in the sharing computer. Because of the nature of the NAT, IP addresses on the local computer are not visible on the Internet. All packets leaving or entering the LAN are sent from or to the IP address of the external adapter on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HomePod
The HomePod is a smart speaker developed by Apple Inc. The HomePod was designed to work with the Apple Music subscription service.

An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple fruit tree, trees are agriculture, cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, ''Malus sieversii'', is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonization of the Americas, European colonists. Apples have Religion, religious and mythology, mythological significance in many cultures, including Norse mythology, Norse, Greek mythology, Greek, and Christianity in Europe, European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after plantin ...

AirPort
An airport is an aerodrome with extended facilities, mostly for commercial air transport. Airports usually consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off and to land or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation. Operating airports is extremely complicated, with a complex system of aircraft support services, passenger services, and aircraft control services contained within the operation. Thus airports can be major employers, as well as important hubs for tourism ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bonjour Browser
Bonjour is Apple's implementation of zero-configuration networking (zeroconf), a group of technologies that includes service discovery, address assignment, and hostname resolution. Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. The software comes built-in with Apple's macOS and iOS operating systems. Bonjour can also be installed onto computers running Microsoft Windows. Bonjour components may also be included within other software such as iTunes and Safari. After its introduction in 2002 with Mac OS X 10.2 as Rendezvous, the software was renamed in 2005 to Bonjour following an out-of-court trademark dispute settlement. Overview Bonjour provides a general method to discover services on a local area network. The software is widely used throughout macOS, and allows users to set up a network without any configuration. it is used to find printers an ...

Local Area Network
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication circuits. Ethernet and Wi-Fi are the two most common technologies in use for local area networks. Historical network technologies include ARCNET, Token Ring and AppleTalk. History The increasing demand and usage of computers in universities and research labs in the late 1960s generated the need to provide high-speed interconnections between computer systems. A 1970 report from the Lawrence Radiation Laboratory detailing the growth of their "Octopus" network gave a good indication of the situation. A number of experimental and early commercial LAN technologies were developed in the 1970s. Cambridge Ring was developed at Cambridge University starting in 1974. Ethe ...
