macbook air



The MacBook Air is a Macintosh notebook computer designed by Apple, described as the "world's thinnest notebook." It is positioned as the ultraportable in Apple's MacBook family and was introduced at the Macworld Conference & Expo on January 15, 2008. The MacBook Air was the first laptop to implement Apple's precision aluminum unibody enclosure.
The MacBook Air has been revised three times since the original release. The first revision introduced higher performance, a larger hard drive, and a Mini DisplayPort. The second revision, introduced with the MacBook Pro family, featured a lower price, higher performance, and longer battery life. It was revised once again in October 2010 with a complete redesign of the enclousure and the addition of a smaller, 11.6-inch (29 cm) display option.

The MacBook Air, designed prominently for thinness and weighing 3 pounds (1.4 kg), was the first MacBook produced using a single sheet of aluminum with Apple's unibody technique. The computer features a glossy LED backlit display and a backlit keyboard, as well as a large trackpad that responds to iPhone-like Multi-Touch gestures such as pinching, swiping, and rotating. With the release of Mac OS X Snow Leopard, the Air's multi-touch trackpad also supports handwriting recognition of Chinese characters.
A flip-down hatch on the right side reveals the ports on MacBook Air: a USB port, a Mini DisplayPort, and a stereo earphone jack. The left side of the computer has a MagSafe adapter for power, and there is an iSight webcam and microphone above the screen.
The MacBook Air was the first subcompact laptop offered by Apple since the full-featured 12" PowerBook G4 was discontinued in 2006. It was also Apple's first computer with an optional solid-state storage drive. ArsTechnica found "moderate" performance improvements of the 64 GB solid-state drive of the first generation Air over the standard 80 GB hard drive in tests. On October 14, 2008, new models were announced boasting improved capacities of 128 GB (solid-state) and 120 GB (hard drive). The Air comes standard with 2 GB non-upgradable RAM. The CPU on the original Air was an Intel Core 2 Duo chip especially designed to be 40 percent the size of the standard Core 2 Duo chip. The current model has a low voltage, small form factor Core 2 Duo "Penryn" with 6 MB of cache, running on a 1066 MHz bus. MacBook Air has no user-replaceable parts. The hard drive, memory, and battery are enclosed within the casing, with memory soldered directly to the logicboard. MacBook Air's battery is enclosed within the case but can be replaced using normal screwdrivers, though it is unclear whether this process would void the notebook's warranty. As part of the out-of-warranty service, Apple offers to replace the battery for a fee.


The optional MacBook Air SuperDrive.
Apple incorporated several features in the design of the MacBook Air, such as the reduction of toxic chemicals like lead, to make it more environmentally "friendly". MacBook Air contains no BFRs and PVC wiring, meets Energy Star Version 5.0 requirements, has a recyclable enclosure, and is rated EPEAT Gold; its display is made from arsenic-free glass and does not contain mercury. To reduce the computer's size and weight, several features were sacrificed. It is Apple's first notebook since the PowerBook 2400c without a built-in removable media drive. It also omits a FireWire port, Ethernet port, line-in, media card slots, and a Kensington Security Slot.
To regain the features of an optical drive, users can either use a separately-available external USB SuperDrive, or the bundled Remote Disc software to access the optical drive of another computer. However, this method only allows for disk browsing or software installation; DVD movies or CDs cannot be watched or listened to. The Remote Disc capability is achieved by the computer wirelessly accessing the optical drive of another Mac or Windows PC that has the Remote Disc program installed. It can also be used to reinstall the system software from the included installation DVD. Remote Disc supports netbooting, so MacBook Air can boot from its installation DVD in another computer's drive. This feature requires Remote Install Mac OS X to be running on the remote computer. The software does not allow the playback or information of DVDs or CDs, nor does it allow the installation of Microsoft Windows. For these features, an external USB drive is required. A single speaker located under the keyboard is included for mono sound.
The MacBook Air includes Mac OS X Snow Leopard pre-installed, along with Apple's iLife multimedia suite.
With the 2008 revisions of the notebook, wired Ethernet connectivity required a separately available USB-to-Ethernet adapter. However, for the 2009 revision, the adapter is included in-the-box. Additionally, in the 2008 revision, the hard drive, graphics, front side bus, processor, memory, battery, and port connections were upgraded.

macbook pro


The MacBook Pro is a line of Macintosh portable computers introduced in January 2006 by Apple Inc. It replaced the PowerBook G4 and was the second model to be announced in the Apple–Intel transition (after the iMac). Positioned at the high end of the MacBook family, the MacBook Pro is currently produced in three sizes: the 13-, 15-, and 17- inch.
There have been two designs for the MacBook Pro, both using aluminum. The first design was largely a carry-over from the PowerBook G4 and used the Intel Core central processing units as opposed to the PowerPC G4 chips used in the model it replaced. It was first released as a 15-inch model in January 2006, followed by a 17-inch model in April of the same year. These original models received several updates and were upgraded with Core 2 Duo processors in late 2006.
The second "unibody" model has a more tapered design with most of the casing made from a single block of aluminum. This design was introduced with the 15-inch MacBook Pro in October 2008, along with the 13-inch aluminum unibody MacBook. The 17-inch model was updated with the same design the following January, also introducing the built-in battery that was later used in the rest of the MacBook Pro line from June and in the regular MacBook from October 2009. Apple updated the unibody line in April 2010 with Intel Core i5 and Core i7 processors in the 15- and 17-inch models, while the 13-inch models retained the Core 2 Duo processors.

macbook


The MacBook is a brand of Macintosh notebook computers built by Apple Inc. First introduced in May 2006, it replaced the iBook and 12-inch PowerBook series of notebooks as a part of the Apple–Intel transition. Positioned as the low end of the MacBook family, the MacBook is aimed at the consumer and education markets. It is the best-selling Macintosh in history, and according to the sales-research organization NPD Group in October 2008, the mid-range model of the MacBook was the single best-selling laptop of any brand in U.S. retail stores for the preceding five months.
There have been three separate designs of the MacBook: the original model uses a combination of polycarbonate and fibreglass casing that was modelled after the iBook G4. The second type, introduced in October 2008 alongside the 15-inch MacBook Pro, used a similar unibody aluminum casing to the 15-inch Pro, and was updated and rebranded as the 13-inch MacBook Pro at the 2009 Apple Worldwide Developers Conference in June 2009. A third design, introduced in October 2009, uses a unibody polycarbonate shell as aluminum is now reserved for the higher-end MacBook Pro.

apple earbuds


History

The white earphones (or "earbuds") that ship with all iPods have become symbolic of the brand. Advertisements feature them prominently, often contrasting the white earphones (and cords) with people shown as dark silhouettes that are usually seen on iTunes gift cards. The original earphones came with the first generation iPod. They were revised to be smaller after Apple received complaints of the earbuds being too large. The revised earphones were shipped with second through early fifth generation iPods, the iPod Mini, and the first generation Nanos. The earbuds were revised again in 2006, featuring an even smaller and more streamlined design. This third design was shipped with late fifth generation iPods and the second-generation nanos. All first generation iPod Shuffles and the second generation up until 30 January 2007 (when color models were introduced) were shipped with the second design; those that shipped after that date were distributed with the third design of the earbuds. The third generation iPod Shuffle comes with the earphones with remote on the right earphone, and third generation iPod Touch comes with the earphones with remote and mic on the right earphone.

Varieties

There are currently 4 varieties of iPod headphones: The basic Apple Earphones (no controls), which ships with all iPods except the 3rd Gen. Shuffle and 3rd Gen. Touch (8 GB); the Shuffle Apple Headphones (with Remote), which ships only with the 3rd Gen. Shuffle; the Apple Earphones (with Remote and Mic), which ships with the iPhone 3GS, iPod Touch 3rd Gen, iPhone, and is also sold independently; and the optional "premium" Apple In-Ear Headphones (with Remote and Mic), introduced on September 9, 2008, which are sold independently. The last three of these versions have buttons that allow users to adjust volume and control music and video playback. The control capsule located on the cable of the right earpiece includes three buttons and a microphone on the last two versions. Users can: adjust volume by pressing the + and - buttons, control music and video playback — including play/pause and next/previous — by pressing the center button, and record voice memos on supported iPod and iPhone models. There have been many reports of moisture problems with the remote/mic earbuds. The original iPhone and iPhone 3G came with a modified version of the Apple Headphones - The iPhone Stereo Headset. These were the Apple Headphones but with an additional clicker and remote on the right side of the headphones. The iPhone headset differs from the Apple Headphones with Remote and Mic by not including the volume control.

the ipod shuffle

First generation

Released on January 11, 2005, the first generation iPod Shuffle weighed 0.78 ounces (22 g) and was designed to be easily loaded with a selection of songs and to play them in random order. According to Apple, owners of existing iPods had often left the music selection to "shuffle", and the new iPod Shuffle was a way of implementing that in a much more cost-effective fashion. It relies on the use of an "autofill" feature in iTunes, which can select songs at random from a user's music library (or from a specific playlist) and copy as many as will fit into iPod Shuffle's memory. It can hold up to 240 songs (1 GB model, based on Apple's estimate, of four minutes per song and 128 kbit/s AAC encoding).

t lacks a display and the trademark scroll wheel, playlist management features, and is missing the games, address book, calendar, alarm, and notes capability of larger iPods; it cannot be used with iSync. Due to the codec not being ported, it is incapable of playing Apple Lossless and AIFF audio files.

The front of the iPod Shuffle has buttons for Play/Pause, Next Song/Fast Forward, Previous Song/Fast Reverse, and up and down volume adjustment. On the reverse, it has a battery level indicator light (activated by a button) and a three-position switch to turn the unit off or set it to play music in order or shuffled. It plugs directly into a computer's USB port (either 1.1 or 2.0), through which it also recharges its battery, which has an expected life of around 12 hours between charges. The USB plug is hidden beneath a cap. The unit also 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.


Second generation

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 actually started shipping on Friday, November 3, 2006. The new 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.

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 is also able to act as a flash drive, just like the first generation iPod Shuffle. However, unlike the first generation iPod Shuffle, the second generation does not have a built-in USB connector. This means that the docking station is required for connection to a computer on the second generation model.
The second generation Shuffle can play MP3, MP3 VBR, AAC, Protected AAC, Audible (formats 2, 3 and 4), WAV and AIFF. Due to its low processing power the only iTunes-supported file format that the iPod does not support is Apple Lossless.[citation needed] Using large file sizes inherent of WAV or AIFF files will very quickly fill the device's low 1 GB capacity. iPod Shuffle cannot play music from music video files.

Third generation

The third generation iPod Shuffle was released on March 11, 2009 and is said by Apple to be "jaw-droppingly small" and "The first music player that talks to you" with dimensions of 45.2 x 17.5 x 7.8 mm (1.8 x 0.7 x 0.3 in). It is available with a silver or black brushed aluminum case similar to the second generation iPod Shuffle. This makes it the first iPod Shuffle that is available in black. It features VoiceOver technology that allows song names, artist names, album names and playlist contents and names to be spoken in 20 different languages using the Text-to-Speech incorporated in iTunes 8 and 9. It also has gained support for multiple playlists, in contrast to previous versions of the iPod Shuffle, which allowed only a single playlist.


A third generation iPod Shuffle with headphones.
The third generation iPod Shuffle features a polished steel attachment clip, adopting for the first time the polished steel finishing previously found only on the larger iPods, rather than the brushed aluminum used in the second-generation iPod Shuffle. It also no longer has volume or track controls on the device itself. Instead, the packaged iPod earbuds now include a three-button device on the right earbud cord. This adds the functions of changing between playlists, hearing the song title and artist of the track playing, as well as play/pause, track changes and volume control. It is not possible to change songs or volume with current third-party headphones, since they lack these controls. However, since the iPod Shuffle begins playing music automatically when it is turned on, third-party headphones may still be used in "autoplay" mode (with no volume or playback controls). Some future third-party headphones and headphone adapters will include full support for the iPod Shuffle. The official headphones contain a chip designed by Apple to control the device.

Fourth generation

The fourth generation iPod Shuffle was announced on September 1, 2010. It features the return of clickable track and volume controls from the first two generations. The control pad is 18% larger than the second generation of iPod shuffle and the model also features VoiceOver from the third generation in twenty-five languages. It also features Genius and handles multiple playlists. They are currently being sold in 2 GB models with US pricing for the device announced to start at US$49. In the UK, the price is £39.

the ipad


The iPad is a tablet computer designed and developed by Apple. It is particularly marketed as a platform for audio and visual media such as books, periodicals, movies, music, and games, as well as web content. At about 700 grams (25 ounces), its size and weight are between those of most contemporary smartphones and laptop computers. Apple released the iPad in April 2010, and sold 3 million of the devices in 80 days.[6]
The iPad runs the same operating system as the earlier iPod Touch and iPhone, albeit a slightly older version. It can run its own applications as well as ones developed for the iPhone. Without modification, it will only run programs approved by Apple and distributed via its online store.
Like iPhone and iPod Touch, the iPad is controlled by a multitouch display — a break from most previous tablet computers, which used a pressure-triggered stylus. The iPad uses a Wi-Fi data connection to browse the Internet, load and stream media, and install software. Some models also have a 3G wireless data connection. The device is managed and synced by iTunes on a personal computer via USB cable.
Media reaction to the device has generally been neutral or positive, with more positive reaction after the device was launched.
