AAUI was part of a system of Ethernet peripherals that tried to make connecting to Ethernet much easier. Apple’s system was called FriendlyNet.

The transceiver would automatically terminate the network if a cable was not attached to one of the sides. Thus the number of mistakes that could be made hooking up a thinnet network was reduced considerably. Since any of these mistakes would disable the network in an area this was a significant improvement. FriendlyNet equipment was quite expensive and even third-party AAUI transceivers were rather expensive.

Apple eventually abandoned the system and sold off the name. By the time AAUI was nearing the end of its life, an AAUI transceiver could cost as much or more than the cost of a low-cost Ethernet card on the PC—a disproportionate amount—as network cards for PCs did not become commodity items until the spread of broadband internet in the early 21st century.

Many third parties also created AAUI transceivers.

Most made simplifications to the connectors and cables, presumably to reduce costs. Most third parties, as well as any non-Apple equipment would use standard 10BASE2 cabling, including T-connectors and manual termination. Additionally, Apple’s 10BASE2 cables were not really feasible for all uses since they only came in fixed lengths and the ends were not detachable, making it very difficult to wire them through walls.

Unfortunately, when mixing and matching Apple and non-Apple 10BASE2 devices, there were many seemingly natural configurations of cables and connectors which would cause the network to become unreliable or unusable in the area, reducing the value of the complex and proprietary Apple 10BASE2 wiring system.

AUI used a full-sized pin D connector model DA that used a sliding clip for mechanical connections in place of thumbscrews. AAUI replaced these with a small position, 0.

The connector may have been changed to avoid confusion with the monitor port on early Macintosheswhich also used a pin D connector. Third-party AAUI devices often omitted this sheath, requiring the user to directly squeeze small tabs on the sides of the plug housing to detach the hooks. This article is based on material taken from the Free On-line Dictionary of Computing prior to 1 November and incorporated under the “relicensing” terms of the GFDLversion 1. The electrical AUI connection Interior of Inteerface LocalTalk interface box.

The connectors feature automatic electrical termination of the LocalTalk signal bus; insertion of a LocalTalk bus cable depresses a normally closed switch fileyype the connector, disabling termination for that connector. LocalTalk is a particular implementation of the physical layer of the AppleTalk networking system from Apple Computer. LocalTalk specifies a system of shielded twisted pair cabling, plugged into self-terminating transceivers, running at a intercace of Farallon’s competing PhoneNet transceiver.

Networking was envisioned in the Macintosh during planning, so the Mac was given expensive RS capable serial ports. The ports were driven by the Zilog SCC, which could serve as either a standard UART or handle the much more complicated HDLC protocol, which was a packet oriented protocol that incorporated addressing, bit-stuffing, and pac The Power Mac G5, the last model of the series.

The Power Macintosh, later Power Mac, is a family of personal computers that were designed, manufactured, and sold by Apple Computer, Inc. Software written for the Motorola and processors that were used in Macintoshes up to that point would not run on the PowerPC natively, so a Mac 68k emulator was included with System 7.

While the emulator provided good compatibility with existing Macintosh software, performance was about one-third slower than comparable Macintosh Quadra machines. Disk interface families Disk drive interfaces have evolved from simple interfaces requiring complex controllers to attach to a computer into high level interfaces that present a consistent interface to a computer system regardless of the internal technology of the hard disk drive.

The following table lists some common HDD interfaces in chronological order: The SCSI standards define commands, protocols, electrical, optical and logical interfaces. SCSI is most commonly used for hard disk drives and tape drives, but it can connect a wide range of other devices, including scanners and CD drives, although not all controllers can handle all devices. The SCSI standard defines command sets for specific peripheral device types; the presence of “unknown” as one of these types means that in theory it can be used as an interface to almost any device, but the standard is highly pragmatic and addressed toward commercial requirements.

Notes is a notetaking app developed by Apple. It functions as a service for making short text notes, which can be synchronised between devices using Apple’s iCloud service.

The application uses a similar interface on iOS and macOS, with a textured paper background for notes and light yellow icons, suggesting pencil or crayon. Filetyprboth applications used a strongly skeuomorphic interface, with a lined paper design; the Mountain Lion intrface placed this inside a leather folder. They are named for their characteristic D-shaped metal shield.

When they were introduced, D-subs were among the smallest connectors used on computer systems. Description, nomenclature, and variants DA, DB, DC, DD, and DE sized connectors The DB13W3 connector with three coaxial connections and ten ordinary pins A D-sub contains two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield that provides mechanical support, ensures correct orientation, and may screen against electromagnetic interference.

The part containing pin contacts is called the male connector or plug, while that containing socket contacts is called the female connector or socket. The socket’s shield fits tightly inside the plug’s shield. Panel mounted connectors usually have threaded nuts that accept screws on the cable end connector cover that are used for locking the connec The internals of the original 20″ iMac G5.

Many hardware components can be seen. Hardware of the Macintosh or Mac is produced solely by Apple Inc. Apple directly sub-contracts hardware production to external OEM companies, maintaining a high degree of control over the end product.

Apple buys certain components wholesale from third-party manufacturers.

The current Mac product family uses Intel x processors. Macs include two standard data transfer ports: USB was introduced in the iMac G3 and is ubiquitous today; Thunderbolt is intended for high-performance devices such as external graphics cards.

Mail riletype known as Apple Mail or Mail. NeXTMail was innovative for its time, supporting rich text formatting with images and voice messaging. CarPlay is an Apple standard that enables a car radio or head unit to be a display and also act as a controller for an iPhone. It is available on all iPhone 5 and later models with at least iOS 7.

Most worldwide vehicle manufacturers have said they will be incorporating CarPlay into their infotainment systems over time.

CarPlay can also be retrofitted to most vehicles with aftermarket vehicle audio hardware. Four PCI Express bus card slots from top to 2nd bottom: This expression covers all related hardware components wire, optical fiber, etc. Modern computer buses can use both parallel and bit serial connections, and can be wired in either a multidrop electrical parallel or daisy chain topology, or connected by switched hubs, as in the case of USB.

Background and nomenclature Computer systems generally consist of three main parts: AppleTalk is a discontinued filetypf suite of networking protocols developed by Apple Inc. AppleTalk includes a number of features that allow local area networks to be connected with no prior pnout or the need for a centralized router or server of any sort.

Connected AppleTalk-equipped systems automatically assign addresses, update the distributed namespace, and configure any required inter-networking routing.


AppleTalk was released inand was the primary protocol used by Apple devices through the s and s. AppleTalk support was also aul in most networked printers especially laser printerssome file servers, and a number of routers.

Many of AppleTalk’s more advanced autoconfiguration fe All generations of the iPhone use Apple’s iOS mobile operating system software. The first-generation iPhone was released on June 29,and multiple new hardware iterations with new iOS releases have been released since. The user interface is built around the device’s multi-touch screen, including a virtual keyboard.

The iPhone has Wi-Fi and can connect to cellular networks. An iPhone can shoot video though this was not a standard feature until the iPhone 3GStake photos, play music, send and receive email, browse the web, send and receive text messages, follow GPS navigation, record notes, perform mathematical calculations, and receive visual voicemail.

Other functionality, such as video games, reference works, and social networking, can be enabled by downloading mobile apps. Apple has linout eleven generations o It comprises a number of mechanisms that are enforced by the kernel. A centerpiece is the protection of system-owned files and directories against modifications by processes without a specific “entitlement”, even when executed by the root user or a user with root privileges sudo. Apple says that the root user can be a significant risk factor to the system’s security, especially on systems with a single user account on which that user is also the administrator.

System Integrity Protection is enabled by default, but can be disabled.

In one of the WWDC developer sessions, Apple engineer Pierre-Olivier Martel described unrestricted root access as one of the remaining weaknesses of the system, saying that “[any] piece of malware IEEE is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer.

It was developed in the late s and early s by Apple, which called it FireWire. The interface is also known by the brands i. The copper cable it uses in its most common implementation can be up to 4. Power is also carried over this cable, allowing devices with moderate power requirements to operate without a separate power supply.

FireWire is also available in Cat 5 and optical fiber versions. This is a list of computing and IT acronyms and abbreviations.

Calendar is a personal calendar app made by Apple Inc. It offers online cloud backup of calendars using Apple’s iCloud service, or can synchronize with other calendar services, including Google Calendar and Microsoft Exchange Server. Originally released as a free download for Mac OS X v OS X Mountain Lion version Named to signify its status as a refinement of the previous Mac OS X version, Lion, Apple’s stated aims in developing Mountain Lion were to allow users to more easily manage and synchronise content between multiple Apple devices and to make the operating system more familiar.

The operating system gained the new malware-blocking system Gatekeeper and integration with Apple’s online Game Center and iCloud services, while the Safari web browser was updated to version 6.

The interface is primarily used to connect a video source to a display device such as a computer monitor, and it can also carry audio, USB, and other forms of data. The interface is backward compatible with other interfaces, such as HDMI and DVI, through the use of either active or passive adapters. Overview DisplayPort is the first display interface to rely on packetized data transmission, a form of digital communication found in technologies such as Ethernet, USB, and PCI Express.

It permits the use of internal and external display connections, and unlike legacy standards that transmit a clock signal with each output, the DisplayPort protocol is based on small data packets known as micro packets, which can HP Jetdirect is the name of a interrface sold by Hewlett-Packard that allows computer printers to be directly attached to a Local Area Network.
