The AirPort Express was a Wi-Fi base station product from Apple Inc. part of the AirPort product line. While more compact and in some ways simpler than another Apple Wi-Fi base station, the AirPort Extreme, the Express offered audio output capability the Extreme lacks; the AirPort Express was the first AirPlay device to receive streamed audio from a computer running iTunes on the local network. AirPort Express outperformed the stringent requirements of the ENERGY STAR Program Requirements for Small Network Equipment Version 1.0. According to a Bloomberg report on November 21, 2016, "Apple Inc. has disbanded its division that develops wireless routers, another move to try to sharpen the company’s focus on consumer products that generate the bulk of its revenue, according to people familiar with the matter."In an April 2018 statement to 9to5Mac, Apple announced the discontinuation of its AirPort line leaving the consumer router market. Apple will continue supporting the AirPort Express, however the company now provides a list of recommended features when consumers are searching for a new wireless router.
When connected to an Ethernet network, the Express could function as a wireless access point. The last model allowed up to 50 networked users, it could be used as an Ethernet-to-wireless bridge under certain wireless configurations. It could be used to extend the range of a network, as well as audio server; the model introduced in June 2012 included two Ethernet ports: one WAN and one LAN. The first version was introduced by Apple on 7 July 2004, included an analog–optical audio mini-jack output, a USB port for remote printing or charging the iPod, one Ethernet port; the main processor of the 802.11g AirPort Express was a Broadcom BCM4712KFB wireless networking chipset, which had a 200 MHz MIPS processor built in. The audio was handled by a Texas Instruments Burr-Brown PCM2705 16-bit digital-to-analog converter. An updated version supporting the faster 802.11 Draft-N draft specification and operation in either of the 2.4 GHz and 5 GHz bands, with all other features identical, was introduced by Apple in March 2008.
The revised unit included an 802.11a/n mode, which allows adding Draft-N to an existing 802.11b/g network without disrupting existing connections, while preserving the increased throughput that Draft-N can provide. Up to 10 wireless units can connect to this AirPort Express; the AirPort Express uses an audio connector that combines a 3.5 mm minijack socket and a mini-TOSLINK optical digital transmitter, allowing connection to an external digital-to-analog converter or amplifier with internal DAC. Standard audio CDs ripped in iTunes into Apple Lossless format streamed to the AirPort Express will output a bit-for-bit identical bitstream when compared to the original CD. DTS-encoded CDs ripped to Apple Lossless audio files - which decode as digital white noise in iTunes - will play back when the AirPort Express is connected via TOSLINK to a DTS-compatible amplifier–decoder; this is limited to 44.1 kHz when streaming from iTunes. Any higher quality content, such as high fidelity audio that uses up to 24-bit and/or 192 kHz will be truncated down to 16-bit and 44.1 kHz.
The audio output feature of the AirPort Express on a system running Mac OS X Lion or earlier can only be used to wirelessly stream audio files from within iTunes to an attached stereo system. It cannot be used to output the soundtrack of iTunes video content to an attached stereo. OS X Mountain Lion introduced a feature to output system-wide audio directly to AirPort Express; this allows output of the audio of protected video content within iTunes, correctly maintains the audio sync with the image displayed on-screen. Video is synced with output audio when playing the video through an AirPort Express if the video is in a format supported by QuickTime Player. For Windows and Mac operating systems there are a few software options available for streaming system-wide audio to the AirPort Express, such as Airfoil, TuneBlade and Porthole. On August 28, 2018 Apple added AirPlay 2 support to the 2012 AirPort Express, giving it access to HomePod like features July 2004: AirPort Express released March 2008: AirPort Express 802.11n released June 2012: AirPort Express 802.11n released AirPort Extreme AirPort Time Capsule
The Macintosh is a family of personal computers designed and sold by Apple Inc. since January 1984. The original Macintosh was the first mass-market personal computer that featured a graphical user interface, built-in screen and mouse. Apple sold the Macintosh alongside its popular Apple II family of computers for ten years before they were discontinued in 1993. Early Macintosh models were expensive, hindering its competitiveness in a market dominated by the Commodore 64 for consumers, as well as the IBM Personal Computer and its accompanying clone market for businesses. Macintosh systems still found success in education and desktop publishing and kept Apple as the second-largest PC manufacturer for the next decade. In the early 1990s, Apple introduced models such as the Macintosh LC II and Color Classic which were price-competitive with Wintel machines at the time. However, the introduction of Windows 3.1 and Intel's Pentium processor which beat the Motorola 68040 in most benchmarks took market share from Apple, by the end of 1994 Apple was relegated to third place as Compaq became the top PC manufacturer.
After the transition to the superior PowerPC-based Power Macintosh line in the mid-1990s, the falling prices of commodity PC components, poor inventory management with the Macintosh Performa, the release of Windows 95 saw the Macintosh user base decline. Prompted by the returning Steve Jobs' belief that the Macintosh line had become too complex, Apple consolidated nearly twenty models in mid-1997 down to four in mid-1999: The Power Macintosh G3, iMac, 14.1" PowerBook G3, 12" iBook. All four products were critically and commercially successful due to their high performance, competitive prices and aesthetic designs, helped return Apple to profitability. Around this time, Apple phased out the Macintosh name in favor of "Mac", a nickname, in common use since the development of the first model. Since their transition to Intel processors in 2006, the complete lineup is based on said processors and associated systems, its current lineup includes four desktops, three laptops. Its Xserve server was discontinued in 2011 in favor of the Mac Mac Pro.
Apple has developed a series of Macintosh operating systems. The first versions had no name but came to be known as the "Macintosh System Software" in 1988, "Mac OS" in 1997 with the release of Mac OS 7.6, retrospectively called "Classic Mac OS". In 2001, Apple released Mac OS X, a modern Unix-based operating system, rebranded to OS X in 2012, macOS in 2016; the current version is macOS Mojave, released on September 24, 2018. Intel-based Macs are capable of running non-Apple operating systems such as Linux, OpenBSD, Microsoft Windows with the aid of Boot Camp or third-party software. Apple produced a Unix-based operating system for the Macintosh called A/UX from 1988 to 1995, which resembled contemporary versions of the Macintosh system software. Apple does not license macOS for use on non-Apple computers, however System 7 was licensed to various companies through Apple's Macintosh clone program from 1995 to 1997. Only one company, UMAX Technologies was licensed to ship clones running Mac OS 8.
Since Apple's transition to Intel processors, there is a sizeable community around the world that specialises in hacking macOS to run on non-Apple computers, which are called "Hackintoshes". The Macintosh project began in 1979 when Jef Raskin, an Apple employee, envisioned an easy-to-use, low-cost computer for the average consumer, he wanted to name the computer after his favorite type of apple, the McIntosh, but the spelling was changed to "Macintosh" for legal reasons as the original was the same spelling as that used by McIntosh Laboratory, Inc. the audio equipment manufacturer. Steve Jobs requested that McIntosh Laboratory give Apple a release for the newly spelled name, thus allowing Apple to use it; the request was denied, forcing Apple to buy the rights to use this name. In 1978, Apple began to organize the Apple Lisa project, aiming to build a next-generation machine similar to an advanced Apple II or the yet-to-be-introduced IBM PC. In 1979, Steve Jobs learned of the advanced work on graphical user interfaces taking place at Xerox PARC.
He arranged for Apple engineers to be allowed to visit PARC to see the systems in action. The Apple Lisa project was redirected to utilize a GUI, which at that time was well beyond the state of the art for microprocessor capabilities. Things had changed with the introduction of the 32-bit Motorola 68000 in 1979, which offered at least an order of magnitude better performance than existing designs, made a software GUI machine a practical possibility; the basic layout of the Lisa was complete by 1982, at which point Jobs's continual suggestions for improvements led to him being kicked off the project. At the same time that the Lisa was becoming a GUI machine in 1979, Jef Raskin started the Macintosh project; the design at that time was for a easy-to-use machine for the average consumer. In
The iPod Classic is a portable media player created and marketed by Apple Inc. There were six generations of the iPod Classic, as well as a spin-off, re-integrated into the main iPod line. All generations used a 1.8-inch hard drive for storage. The "classic" suffix was formally introduced with the rollout of the sixth-generation iPod on September 5, 2007. Prior to this, all iPod Classic models were referred to as iPods, it was available in silver or black replacing the "signature iPod white". On September 9, 2014, Apple discontinued the iPod Classic; the sixth-generation 160GB iPod Classic was the last Apple product in the iPod line to use the original 30-pin iPod connector and the iconic Click Wheel. IPods with color displays use text, with sliding animations. All iPods have five buttons and the generations have the buttons integrated into the click wheel — a design which gives an uncluttered, minimalist interface, though the circuitry contains multiple momentary button switches; the buttons are: Menu: to traverse backwards through the menus, toggle the backlight on older iPods, jump to the main menu on newer iPods Center: to select a menu item Play / Pause: this doubles as an off switch when held Skip Forward / Fast Forward Skip Backwards / Fast Reverse The iPod's operating system is stored on its dedicated storage medium.
An additional NOR flash ROM chip contains a bootloader program that tells the device to load its OS from the storage medium. Each iPod has 32 MB of RAM, although the 60GB and 80GB fifth generation, the sixth-generation models have 64 MB. A portion of the RAM is used to hold the iPod OS loaded from firmware, but the majority of it serves to cache songs from the storage medium. For example, an iPod could spin its hard disk up once and copy 30 MB of upcoming songs into RAM, thus saving power by not requiring the drive to spin up for each song. Custom firmware has been developed such as Rockbox and iPodLinux which offer open-source alternatives to the standard firmware and operating system. In March 2002, Apple added limited PDA-like functionality: text files can be displayed, while contacts and schedules can be viewed and synchronized with the host computer; some built-in games are available, including Brick, Solitaire, iPod Quiz. A firmware update released in September 2006 brought some extra features to fifth-generation iPods including adjustable screen brightness, gapless playback, downloadable games.
However, as of September 30, 2011, these games are no longer available on the iTunes Store. Apple introduced the first-generation iPod on October 23, 2001, with the slogan "1,000 songs in your pocket", they went on sale on November 10, 2001. The first iPod had a monochrome LCD screen and featured a 5GB hard drive capable of storing 1,000 songs encoded using MP3 and was priced at US$399. Among the iPod's innovations were its small size, achieved using a 1.8" hard drive, whereas its competitors were using 2.5" hard drives at the time, its easy-to-use navigation, controlled using a mechanical scroll wheel, a center select button, four auxiliary buttons around the wheel. The iPod had a rated battery life of ten hours. On March 20, 2002, Apple introduced a 10GB model of the first-generation iPod for US$499. VCard compatibility was added, as well as allowing iPods to display business card information synced from a Mac; the second-generation of the iPod was introduced on July 17, 2002. Using a similar body style as the first generation, the top of the iPod was redesigned, switching from a single swooping cutout in the back plate to mount the firewire port, hold switch and headphone assembly, to individual ports being cut into the back plate to allow these ports to be accessed.
Furthermore, the hold switch was redesigned, a cover was added to the FireWire port, the mechanical wheel was replaced with a touch-sensitive wheel. The second-generation class was available in 10GB for US$399 and 20GB for US$499; the first-generation 5GB iPod was carried over, but its price was reduced to US$299. Notably, the second-generation iPods and the updated first-generation iPod were now Windows-compatible; these versions were bundled with Musicmatch Jukebox. At that time iTunes was Mac unavailable for Windows. In December 2002, Apple unveiled its first limited edition iPods, with either Madonna’s, Tony Hawk’s, or Beck’s signature or No Doubt's band logo engraved on the back for an extra US$50. On April 29, 2003, Apple announced a redesigned third-generation iPod. Thinner than the previous models, the third-generation models replaced the FireWire port with a new Dock Connector and introduced the Touch Wheel, a non-mechanical interface with the four auxiliary buttons located in a row between the screen and the touch wheel.
The front plate had rounded edges, the rear casing was rounded as well. A new wired remote connector was introduced. Whereas first and second-generation iPods had an auxiliary ring around the headphone port for the remote, the third-generation iPods had a 4-pin jack adjacent to the headphone port. A 10GB model was sold for US$299, a 15GB model for US $399, a 30GB model for US $499. All iPods were now compatible with Mac and Windows out of the box, was requiring Windows users to reformat the iPod before use on a PC and both iTunes and Musicmatch Jukebox were bundled with all iPods; the battery life was reduced to 8 hours due to the use of a lithium-i
The iPod Nano is a portable media player designed and marketed by Apple Inc. The first generation model was introduced on September 7, 2005, as a replacement for the iPod Mini, using flash memory for storage; the iPod Nano went since its introduction. Apple discontinued the iPod Nano on July 27, 2017. Development work on the design of the iPod Nano started only nine months before its launch date; the Nano was launched in two colors with two available sizes: 2 GB and 4 GB. On February 7, 2006, Apple updated the lineup with the 1 GB model. Apple released some accessories, including armbands and silicone "tubes" designed to bring color to the Nano and protect it from scratches, as well as a combination lanyard-earphone accessory that hangs around the neck and avoids the problem of tangled earphone cords; the current models with Bluetooth headphones have a similar advantage. On September 7, 2005, Apple introduced the iPod Nano at a media event with Steve Jobs pointing to the small watch pocket in his jeans and asking, "Ever wonder what this pocket is for?"
Advertising emphasized the iPod Nano's small size: 40 millimetres wide, 90 millimetres long, 6.9 millimetres thick and weighing 42 grams. The stated battery life was up to 14 hours, while the screen was 176×132 pixels, 38 millimetres diagonal, displaying 65,536 colors. 1, 2, 4 GB capacities were available. On November 11, 2011, Apple announced a recall on this model of iPod nano; the recall was issued due to a battery overheat issue. This recall applied to iPod nanos sold between September 2005 and December 2006. On September 25, 2006, Apple updated the Nano line; the second-generation Nano featured scratch-resistant, anodized aluminum casing like the earlier Mini's design. However, unlike the second-generation Mini, the button labels were grey instead of matching the Nano's casing; the second-generation Nano featured a 40% brighter, "more vibrant" display, a battery life upgrade, storage sizes doubled to 2, 4, 8 GB models. The second generation introduced gapless playback of audio files, along with a new search option.
The 2 GB model was available in silver only. The 4 GB was available in green, silver, or pink, the 8 GB model was only available in black - red was added for 4 and 8 GB models. Apple claimed that the second generation iPod Nano's packaging was "32% lighter with 52% less volume than the first generation", thereby reducing environmental impact and shipping costs. On October 13, 2006, Apple announced a special edition iPod Nano. For each red iPod Nano sold in the United States, Apple donates US$10 to the Product Red initiative, while retaining the regular price. On November 3, 2006, Apple introduced a red 8 GB model, due to "outstanding customer demand", again retaining the same price point of the equivalent black model. Apple updated the Nano again on September 5, 2007; the third-generation Nano featured a 2-inch QVGA screen and a shorter, heavier design, with new colors. New features included browsing via Cover Flow, a new user interface, video playback, support for new iPod Games. Users had to repurchase games bought a month before the debut of the new iPod as they were not supported.
The Nano was announced in a 4 GB version coming in silver and an 8 GB version coming in silver, mint green and Product Red. The battery lasted for approx. 24 hours on audio playback and approx. 5 hours on video playback. On January 22, 2008, Apple released a pink version of the 8 GB iPod Nano. Combining elements from previous generations of the iPod Nano, the third-generation Nano had an aluminum front plate and a stainless steel back plate; the Nano sported a new Minimalistic hold switch, similar to the iPod Shuffle's power switch, moved to the bottom of the player. The 2-inch screen had the smallest dot pitch of any Apple product, having the same pixel count as the 2.5-inch display of the iPod Classic. On October 6, 2007, Apple released a firmware update via iTunes, said to improve Cover Flow and yield faster menu navigation; the update was released for the iPod Classic. On November 28, 2007, Apple released another firmware update via iTunes, which included unspecified bugfixes. January 15, 2008 saw the release of version 1.1, which added support for iTunes movie rentals, music song lyrics support and included more unspecified bugfixes.
Apple released update version 1.1.2 in May 2008 and version 1.1.3 in July 2008 with more bug fixes. At the Apple Let's Rock Event on September 9, 2008, the iPod Nano Fourth Generation was announced, it returned to the narrow form factor of the 1st and 2nd Generation model, while retaining and rotating the 51-millimetre screen from the 3rd gen model. It was thinner than the first and third generation Nano, measuring 90.7 millimetres tall by 38.7 millimetres wide by 6.2 millimetres thick, weighing 36.8 grams. It had a curved aluminum glass screen. Apple claimed the battery would last 24 hours of music playback, only 4 hours of video playback, compared to the 5 hours of the previous generation; the six previous colors were replaced by silver, purple, light blue, yellow, orange and pink, for a total of n
The iPod Shuffle is a digital audio player designed and marketed by Apple Inc. It was the smallest model in Apple's iPod family, was the first iPod to use flash memory; the first model was announced at the Macworld Conference & Expo on January 11, 2005. The iPod Shuffle was discontinued by Apple on July 27, 2017. Released on January 11, 2005 during the Macworld expo, the first-generation iPod Shuffle weighed 0.78 ounces, was designed to be loaded with a selection of songs and to play them in random order. According to Apple, owners of existing iPods had left the music selection to "shuffle", the new iPod Shuffle was a way of implementing that in a much more cost-effective fashion, it relied on the use of an "autofill" feature in iTunes, which selected songs at random from a user's music library and copied as many as would fit into the iPod Shuffle's storage. The first generation could hold up to 240 songs, it used the SigmaTel STMP35xx system on a chip and its software development kit v2.6, a flash memory IC, USB rechargeable lithium cell.
The STMP35xx SOC and its software was the most integrated portable MP3 playback system at release time and SigmaTel was Austin's largest IPO capturing over 60% of flash based MP3 player world market share in 2004. In 2005, peak iPod first-generation Shuffle production occurred at a hundred thousand units per day, at the Asus factory, it lacked a display, the trademark scroll wheel, playlist management features, the games, address book, calendar and notes capability of larger iPods. Due to the codec not being ported, it was incapable of playing Apple AIFF audio files. Due to superior audio technology in the SigmaTel STMP35xx SOC and SDK, the first generation had a better bass response than a fourth-generation iPod, according to a review published days after its release. ITunes offered some new features for the iPod Shuffle. One was the ability to reduce the bit rate of songs to 128 kbit/s AAC; the conversion is done automatically, with the original file left untouched on the computer and the smaller file sent to the iPod Shuffle.
Older versions of iTunes allowed an iPod Shuffle playlist to be viewed and changed while the unit is not connected. However, this functionality is no longer a part of iTunes as of iTunes 7; the front of the iPod Shuffle had buttons for Play/Pause, Next Song/Fast Forward, Previous Song/Fast Reverse, up and down volume adjustment. On the reverse, it had a battery level indicator light and a three-position switch to turn the unit off or set it to play music in order or shuffled, it plugged directly into a computer's USB port, through which it recharged its battery, which has an expected life of around 12 hours. The USB plug is hidden beneath a cap; the unit comes with a lanyard that attaches to the iPod Shuffle via an attached cap and this allows the user to wear the iPod Shuffle around his or her neck. The first generation could be used as a USB flash drive. ITunes allowed users to set how much of the drive would be allowed for storing files, how much would be used for storing music. On September 12, 2006, Apple announced the release of the second-generation iPod Shuffle, calling it "the most wearable iPod ever".
First shipments of the unit were slated for an October 2006 arrival, but started shipping on Friday, November 3, 2006. The second generation featured a lone 1 GB model in a silver brushed aluminum case, similar to the second-generation iPod Nano and the older iPod Mini; the new model was less than half the size of the first-generation model at 41.2 x 27.3 x 10.5 mm, was the size of the iPod Radio Remote. Apple claimed it was the "world's smallest MP3 player"; this generation included the new built-in belt clip, the actual unit itself was thinner, with the entire device weighing only 15.5 g. The power/shuffle/no shuffle switch from the first-generation version was separated into two controls to avoid an accidentally selected mode of operation; the formatting of the iPod itself was new to Apple, as the second-generation Shuffle only formatted itself to FAT32. On the second-generation iPod Shuffle, USB connectivity is provided via an included piece of hardware which acts as a docking station for the transfer of data and the recharging of the iPod's internal battery through its headphone jack.
The second-generation iPod Shuffle was able to act as a flash drive, just like the first-generation iPod Shuffle. However, unlike the first-generation iPod Shuffle, the second generation did not have a built-in USB connector; this means. The second-generation Shuffle could play MP3, MP3 VBR, AAC, Protected AAC, Audible, WAV and AIFF. Due to its low processing power, the only iTunes-supported file format that the iPod did not support is Apple Lossless. On January 30, 2007, Apple announced the addition of four new colors to the iPod Shuffle line - pink, orange and blue, in addition to the original silver color; the orange color was a first for the iPod franchise. They now came with new redesigned headphones that were not included with the original silver model; the box was changed to have gray text instead of the lime-green text. On September 5, 2007, Apple introduced four new colors, including a Product Red version; the new colors were turquoi
Apple Inc. has developed a range of "System on Chip" as well as "System in Package" processors for powering their mobile consumer devices and other tasks. To meet the stringent power and space constraints common to mobile devices, these chips combine a central processing unit with other components into a single compact physical package. Johny Srouji is the executive in charge of Apple's silicon design. Prior to the introduction of the Apple "A" series of SoCs, Apple used several SoCs in early revisions of the iPhone and iPod touch, they were manufactured by Samsung. They integrate a single ARM-based processing core, a graphics processing unit, other electronics necessary to provide mobile computing functions within a single physical package; the APL0098 is a package on package system on a chip, introduced on June 29, 2007 at the launch of the original iPhone. It includes a 412 MHz single-core ARM11 CPU and a PowerVR MBX Lite GPU, it was manufactured by Samsung on a 90 nm process. The first generation iPod touch used it.
The APL0278 is a package on package system on a chip, introduced on September 9, 2008 at the launch of the second generation iPod touch. It includes a 533 MHz single-core ARM11 CPU and a PowerVR MBX Lite GPU, it was manufactured by Samsung on a 65 nm process. The APL0298 is a package on package system on a chip, introduced on June 8, 2009 at the launch of the iPhone 3GS, it includes a 600 MHz single-core Cortex-A8 CPU and a PowerVR SGX535 GPU. It was manufactured by Samsung on a 65 nm process; the APL2298 is a 45 nm die shrunk version of the iPhone 3GS SoC and was introduced on September 9, 2009 at the launch of the third generation iPod touch. The Apple "A" series is a family of "Systems on Chip" used in multiple devices, including some of Apple's portable devices such as certain models of the iPhone, iPad, iPod touch, the Apple TV digital media player, they integrate one or more ARM-based processing cores, a graphics processing unit, cache memory and other electronics necessary to provide mobile computing functions within a single physical package.
They are designed by Apple, manufactured by Samsung and TSMC. The Apple A4 is a package on package system on a chip designed by Apple Inc. and manufactured by Samsung. It combines an ARM Cortex-A8 CPU with a PowerVR GPU, emphasizes power efficiency; the chip commercially debuted with the release of Apple's iPad tablet. It was superseded in the iPad 2, released the following year, by the Apple A5 processor. Apple A4 is based on the ARM processor architecture; the first version released ran at 1 GHz for the iPad and contains an ARM Cortex-A8 CPU core paired with a PowerVR SGX 535 graphics processor built on Samsung's 45-nanometer silicon chip fabrication process. The clock speed for the units used in the iPhone 4 and the iPod touch is 800 MHz; the clock speed for the unit used in the Apple TV has not been revealed. The Cortex-A8 core used in the A4 is thought to use performance enhancements developed by chip designer Intrinsity, subsequently acquired by Apple, in collaboration with Samsung; the resulting core, dubbed "Hummingbird", is able to run at far higher clock rates than other implementations while remaining compatible with the Cortex-A8 design provided by ARM.
Other performance improvements include additional L2 cache. The same Cortex-A8 CPU core used in the A4 is used in Samsung's S5PC110A01 SoC; the SGX535 in the A4 could theoretically push 35 million polygons per second and 500 million pixels per second, although real world performance may be less. The A4 processor package supports PoP installation. Hence, there is a package with two low-power 128 MB DDR SDRAM chips mounted on top of the A4 used in the first-generation iPad, the fourth-generation iPod touch, the second-generation Apple TV; the iPhone 4 has two 256 MB packages for a total of 512 MB. The RAM is connected to the processor using ARM's 64-bit-wide AMBA 3 AXI bus. To support the iPad's demand for high graphics bandwidth, the width of the RAM data bus is double that used in previous ARM11 and ARM9 based Apple devices; the Apple A5 is a system on a chip designed by Apple Inc. and manufactured by Samsung that replaced the A4. The chip commercially debuted with the release of Apple's iPad 2 tablet in March 2011, followed by its release in the iPhone 4S smartphone that year.
Apple claims that compared with its predecessor, the A4, the A5 CPU "can do twice the work" and the GPU has "up to nine times the graphics performance". The A5 contains a dual-core ARM Cortex-A9 CPU with ARM's advanced SIMD extension, marketed as NEON, a dual core PowerVR SGX543MP2 GPU; this GPU can push between 70 and 80 million polygons/second and has a pixel fill rate of 2 billion pixels/second. Apple lists the A5 to be clocked at 1 GHz on the iPad 2's technical specifications page, though it can dynamically adjust its frequency to save battery life; the clock speed of the unit used in the iPhone 4S is 800 MHz. Like the A4, the A5 process size is 45 nm. An updated 32 nm version of the A5 processor was used in the third generation Apple TV, the iPod touch, the iPad Mini, the new version of iPad 2; the chip in the Apple TV has one core locked. The markings of the square package indicates that it is named APL2498, in software, the chip is called S5L8942; the 32 nm variant of the A5 provides around 15% better battery life during web browsing, 30% better when playing 3D games and 20%
IMac is a family of all-in-one Macintosh desktop computers designed and built by Apple Inc. It has been the primary part of Apple's consumer desktop offerings since its debut in August 1998, has evolved through seven distinct forms. In its original form, iMac G3 had a gumdrop or egg-shaped look, with a CRT monitor enclosed by a colored, translucent plastic case, refreshed early on with a sleeker design notable for its slot-loaded optical drive; the second major revision, iMac G4, moved the design to a hemispherical base containing all the main components and an LCD monitor on a moving arm attached to it. The third and fourth major revisions, iMac G5 and the Intel iMac placed all the components behind the display, creating a slim unified design that tilts only up and down on a simple metal base; the fifth major revision shared the same form as the previous model, but was thinner and used anodized aluminum and a glass panel over the entire front. The sixth major revision uses a different display unit, omits the SuperDrive, uses different production techniques from the older unibody versions.
This allows it to be thinner with an edge thickness of 5.9 mm. It includes a dual microphone setup, includes solid-state drive or hard disk storage, or an Apple Fusion Drive, a hybrid of solid state and hard disk drives; this version of iMac was announced in October 2012, with the 21.5-inch version released in November and the 27-inch version in December. In October 2014, the seventh major revision of the 27-inch iMac was announced, whose main feature is a "Retina 5K" display at a resolution of 5120 × 2880 pixels; the new model includes a new processor, graphics chip, IO, along with several new storage options. The seventh major revision of the 21.5-inch iMac was announced in October 2015. Its main feature is a "Retina 4K" display at a resolution of 4096 × 2304 pixels, it has the same new processor, graphics chip, I/O as the 27-inch iMac, along with several new storage options. On June 5, 2017, Apple announced a workstation-class version of the iMac, called the "iMac Pro"; the iMac Pro shares the design and screen of the 5K iMac, but is colored in Space Gray rather than silver.
It comes with standard SSD storage. Apple began shipping the iMac Pro in December 2017; the announcement of iMac in 1998 was a source of controversy and anticipation among commentators, Mac fans, detractors. Opinions were divided over Apple's drastic changes to the Macintosh hardware. At the time, Apple had suffered a series of setbacks as consumers opted for Wintel machines instead of Apple's Performa models. Many in the industry thought that "beleaguered" Apple would soon be forced to start selling computers with a custom interface built on top of one or more potential operating system bases, such as Taligent, Solaris, or Windows 98. Part of Apple's effort to maintain the Mac platform was trying to improve its retail strategy; as these stores developed, they became a detriment to Apple sales, as CompUSA employees were unfamiliar with the Macintosh and directed customers to Wintel boxes instead. The designer behind iMac's case was Jonathan Ive. Ken Segall was an employee at an L. A. ad agency handling Apple's account who came up with the name "iMac" and pitched it to Steve Jobs.
Jobs wanted the product to be called "MacMan", but warmed to Segall's suggestion. Segall says that the "i" stands for "Internet", but represents the product as a personal and revolutionary device. Apple adopted the'i' prefix across its consumer hardware and software lines, such as iPod, iBook, iPhone, iPad and various pieces of software such as the iLife suite and iWork and the company's media player/store, iTunes. Attention was given to the out-of-box experience: the user needed to go through only two steps to set up and connect to the Internet. "There's no step 3!" was the catch-phrase in a popular iMac commercial narrated by actor Jeff Goldblum. Another commercial, dubbed "Simplicity Shootout", pitted seven-year-old Johann Thomas and his border collie Brodie, with an iMac, against Adam Taggart, a Stanford University MBA student, with an HP Pavilion 8250, in a race to set up their computers. Johann and Brodie finished in 8 minutes and 15 seconds, whereas Adam was still working on it by the end of the commercial.
By 2005, it had become more and more apparent that IBM's development for the desktop implementation of PowerPC was grinding to a halt. Apple announced at the Worldwide Developers Conference that it would be switching the Macintosh to the x86 architecture and Intel's line of Core processors; the first Intel-equipped Macs were unveiled on January 10, 2006: the Intel iMac and the introductory MacBook Pro. Within nine months, Apple had smoothly transitioned the entire Macintosh line to Intel. One of the touted side benefits of this switch was the ability to run Windows on Mac hardware. On July 27, 2010, Apple updated its line of iMacs to feature the new Intel Core "i-series" processors across the line; the 21.5" models now feature the Core i3 processor, but these are upgradable to the Core i5. The high end 27" features a Quad-Core i5 processor, upgradable to a Quad-Core i7. On this date Apple announced its new "Apple Magic Trackpad" peripheral, a trackpad similar to that of MacBook Pro for use with iMac or any other Apple computer.
