Plan 9 from Bell Labs is a distributed operating system, primarily used for research. It was developed as the research successor to Unix by the Computing Sciences Research Center at Bell Labs between the mid-1980s and 2002. Plan 9 is most notable for representing all system interfaces, including those required for networking and the user-interface, through the filesystem rather than specialized interfaces. Plan 9 aims to provide users with a workstation-independent working environment through the use of the 9P protocols. Plan 9 continues to be used and developed in some circles as a research operating system and by hobbyists.

Intel Core i7 is a family of several Intel desktop and laptop 64-bit x86-64 processors, the first processors released using the Intel Nehalem microarchitecture and the successor to the Intel Core 2 family. All three current models and two upcoming models are quad-core processors.The Core i7 identifier applies to the initial family of processors codenamed Bloomfield.Intel representatives state that the moniker Core i7 is meant to help consumers decide which processor to purchase as the newer Nehalem-based products are released in the future.The name continues the use of the Core brand.Core i7, first assembled in Costa Rica,was officially launched on November 17, 2008 and is manufactured in Arizona, New Mexico and Oregon, though the Oregon plant has already moved to the next generation 32 nm process.

The price range of this product varies from 560$ to 1000$(USD). IT is most costly processor ever built in commercial market.

Note: here is only brief description of intel new high end processor, so to get full detailed information about the product then you all should vist intel’s official website.

FEATURES ARE:-

(1) A musical Genius.

Intel released its first “true” quad-core processors on Monday with the introduction of its Xeon 7400 series of server chips, formerly called Dunnington. Designed by Intel engineers in Bangalore, India, the chip lineup includes the company’s first quad-core and six-core chips produced on a single piece of silicon.

The Xeon 7400 series is the first chip to come out of Intel’s Bangalore design center. Established in 2002, the center had previously worked on another Xeon server chip called Whitefield. But that chip never made it to market. It was cancelled in 2005, when Intel revised its product road maps to better compete with Advanced Micro Devices, and the Indian design team soon put its focus on Dunnington.

“This is a tremendous accomplishment,” said Praveen Vishakantaiah, the chief architect of Dunnington, discussing the server chip in a phone interview. “No other team has been able to accomplish something like this so fast.”

Moreover, the Bangalore design center is the first Intel team outside the U.S. to complete the design of a 45-nanometer processor, he said.

The Dunnington chip design marks a technical milestone for Intel, as it uses a monolithic die, the term engineers use to describe putting all of the cores on a single piece of silicon.

Intel’s existing quad-core processor lines use two pieces of silicon, each with two cores, packaged together. That approach made the older quad-core chips easier to produce and avoided the manufacturing difficulties that hampered the release of AMD’s Barcelona chip — an x86 server chip with four cores on a single piece of silicon. Those difficulties were compounded by AMD’s transition to a new 65-nanometer manufacturing process.

Semiconductor manufacturing is as much art as it is science, and chip makers can struggle for months to get high yields from a new manufacturing process.

With the introduction of Dunnington — and the upcoming Nehalem line of quad-core processors that also uses a monolithic design — Intel waited until its 45-nanometer process was in mass production, with any technical difficulties presumably ironed out, before making this transition.

Apple late Thursday re-released iTunes 8 for Windows to roll back a buggy driver that had been bricking Windows Vista PCs with dreaded “blue screen of death” crashes since Tuesday.

In a support document posted around 8:30 p.m. EDT on Thursday, Apple urged Vista users who had been unable to synchronize their iPods or iPhones using iTunes 8 to uninstall both iTunes and an Apple-provided device driver, then download and reinstall the entire 75MB package yet again.

From Vista’s “Uninstall a Program” control panel, users should ditch the “Apple Mobile Device Support” driver as well as iTunes itself, then restart the PC. “Re-download and install the updated iTunes 8 installer from www.apple.com/itunes/download,” said Apple. “Do not use the iTunes8Setup or iTunes864Setup file you previously downloaded.”

Users running Microsoft ‘s Vista operating system had reported problems almost as soon as the updated iTunes 8 was posted for download Tuesday. According to scores of users on the Apple support forum, plugging in an iPod or iPhone caused Vista to crash, then display the “blue screen of death” (BSOD), a Windows critical error screen best-known for its blue background.

The BSOD message fingered an Apple-provided USB driver—”usbaapl.sys” in the 32-bit version of Vista, “usbaapl64.sys” in the 64-bit edition of the OS—as the culprit. Windows identifies that driver as “Apple Mobile Device Support” in Vista’s uninstaller.

According to Windows blogger Ed Bott, who first reported on the iTunes re-release, Apple simply dumped buggy versions of usbaapl.sys and usbaapl64.sys, and swapped in older editions from a July iTunes update.

Computerworld confirmed that a copy of iTunes 8 downloaded late Thursday, after Apple re-issued the application, installed the same older 31.2KB driver identified by Bott. InComputerworld’s case, however, the usbaapl.sys driver was date-stamped as July 10, not July 22, as Bott said.

Apple released iTunes 7.7 on July 10 as part of its run-up to the iPhone 3G launch, and the unveiling of both the iPhone 2.0 software and the MobileMe online sync and storage service.

Intel’s latest server chips, the Xeon 7400 series, formerly called Dunnington, are now available in six-core and quad-core models designed to be used in systems with four or more processors.

The new chip line offers a performance bump over its predecessor, the Xeon 7200 series, Intel said. Much of that increase comes from adding a 16MB level 3 cache. The 7400 series processors are the first Xeon chips to use a level 3 cache, which stores data closer to the processor cores, helping to boost overall performance.

“With the level 3 cache, that does contain additional performance for some of the high-compute-intensive and data-intensive enterprise applications,” said Adesh Gupta, regional server platform manager at Intel Asia-Pacific.

The extra cores also help. Unlike desktops and laptops that rarely run applications capable of tapping the full processing power of quad-core chips, many server applications, like virtualization, run better on multi-core processors.

The first processors to come out of Intel’s India Design Center in Bangalore, the Xeon 7400 chips run at clock speeds up to 2.66GHz and have either four or six cores. They are priced ranging from $856 to $2,729, in 1,000-unit quantities. Servers based on the chips will be available starting Tuesday from vendors like Hewlett-Packard, IBM and Dell, among others.

The Xeon 7400 contains all six cores on one piece of silicon, while Intel’s existing line of quad-core Xeon chips pack two pieces of silicon inside a single package. This was possible because the 45-nanometer process used to make the new chip reduces the size of the features on a chip, increases performance and reduces power consumption.

“We knew that this process would help us pack in more transistors,” Gupta said.

The Xeon 7400 series is the last member of Intel’s Penryn chip family to be released. Later this year, the company will shift to a new processor architecture called Nehalem.

Like earlier chips, the Xeon 7400 relies on a memory controller located in an external chip, which can cause memory bottlenecks in certain applications. The level 3 cache helps to alleviate this problem, but cannot eliminate it entirely. Nehalem will move the memory controller onto the processor itself, which is likely to speed up memory access considerably.

Introduced: June 2007

Announced in January 2007 and released the following June, the iPhone marked Apple’s entry into the cellular phone marketplace. Described by Steve Jobs as “a wide-screen iPod with hand controls… a revolutionary mobile phone… [and] a breakthrough Internet communications device,” the iPhone was the first Apple-branded consumer device to run on OS X. Based around a touch-based user interface with a single button, the iPhone was controlled using a variety of one- and two-finger gestured. It included a custom version of Safari that allowed full browsing of any web page, a revamped iPod interface with CoverFlow, integrated access to YouTube and Google Maps, an iChat-like SMS text-messaging interface (iChat itself was missing from the initial release), and a standard set of cellphone apps, such as a calendar, an address book and a calculator.

The iPhone was available exclusively with AT&T voice/data plans, and was limited to EDGE-based network access, rather than the faster 3G wireless networking standard. This was mitigated somewhat by an integrated 802.11g WiFi chipset, which allowed for faster browsing on any available WiFi network.

Though the iPhone officially only supported web-based applications from third-party developers, an underground development effort was quickly organized, and within a few months native 3rd party applications were widely available. Warantee-breaking hardware modifications to “unlock” the iPhone from the AT&T network were also uncovered. The iPhone was sold in two configurations: a 4GB model sold for $499, and an 8GB model for $599.

Introduced: August 2006

Announced at WWDC in August 2006, the Mac Pro completed Apple’s transition to Intel processors, replacing the PowerMac G5 (Late 2005) as Apple’s professional desktop Mac. The Mac Pro was based on two 64-bit, dual-core Intel Xeon 5100 “Woodcrest” processors, which included a 128-bit Vector Engine. The Mac Pro’s case resembled its PowerMac predecessor’s–with the exception of a second optical drive bay–but the interior of the case was completely redesigned. The Xeon processors required less heat-dissapation than G5 processors, allowing a smaller cooling system. The Mac Pro had four easily accessible hard drive bays (for a BTO maximum of 2 TB of storage) and easy access to its 8 RAM slots, which allowed for a Maximum of 16 GB of RAM.

With the Mac Pro, Apple decided to do something different in terms of configuration. Since the majority of Apple’s professional customers tended to heavily-customize their Macs at purchase time, Apple offered a single, heavily customizable Mac Pro model. In effect, this shifted the decision-making for what configurations to sell to the resellers, leaving Apple with a streamlined manufacturing process. The single model sold for $2,499, and included two 2.66 GHz, dual-core Intel Xeon 5100 processors, 1 GB of RAM, a 250 MB hard disk, a SuperDrive, and an Nvidia GeForce 7300GT graphics card with 256MB of VRAM. BTO options included 2.0 and 3.0 GHz processors, up to 16 GB of RAM, up to 2 TB of storage, a second SuperDrive, a variety of graphics cards, and Airport Express and Bluetooth support.

Notes

The 20″ model had the following dimensions and weight: 18.6″ H x 19.4″ W x 7.4″ D, 22 lbs. 256 MB of VRAM was available for both models as a BTO option.

Announced in January 2006 alongside the MacBook Pro, the iMac (Early 2006) was the first desktop Mac based on an Intel processor. Running on the Intel Core Duo processor, which had two processor cores on a single chip, the iMac (Early 2006) was significantly faster than its predecessor, the iMac (iSight), when running Intel-compiled code. It also features faster bus and memory speeds, a better graphics chip set, and a mini-DVI port which featured monitor spanning (a first for consumer Macs). It was available in two configurations: the 17″ model, with a 1.83 GHz Core Duo processor was $1299, and the 20″ model, running at 2.0 GHz, was $1699. The iMac (Early 2006) was discontinued in September 2006, following the release of the Core2 Duo-based iMac (Late 2006).

Notes

The MacBook’s graphics chipset used a portion of main memory as VRAM. Though reported as a 64 MB graphics system, the chipset actually used a minimum of 80 MB of RAM, resulting in a maximum of 432 MB of RAM available for system use in the base system.

Announced in May 2006, The MacBook replaced the existing 12- and 14-inch iBooks and 12-inch PowerBookmodel, completing the transition of Apple’s portable computers to Intel Processors. The MacBook shipped in a newly-designed case, built around a 13.3-inch “glossy” LCD panel, and included many of the system enhancements of the previously announced MacBook Pro: a dual core Intel Core Duo processor, a faster 667 MHz bus speed, a faster and larger Serial-ATA hard drive, an integrated iSight camera, a MagSafe power adaptor, and a bundled remote control with Apple’s Front Row Software. It also included some features previously found only on Apple’s professional laptops: optical audio in/out, a DVI port capable of monitor-spanning, and Gigabit Ethernet. Two features unique to the MacBook were a magnetic latching system with no moving parts, and a resigned recessed keyboard. One potential drawback to the new MacBook was that its graphic chipset used a portion of main memory, resulting in less RAM available for system tasks. This was offset, however, by the MacBook’s two RAM slots, which allowed the installation of up to 2 GB of memory.

The MacBook shipped in three configurations. The low-end model, with a 1.83 GHz Core Duo processor, 512 MB of RAM, a 60 GB hard drive, and a CD-RW/DVD-ROM Combo Drive, sold for $1,099. The middle-end model, with a 2.0 GHz Core Duo processor, 512 MB of RAM, a 60 GB hard drive, and a CD-RW/DVD±RW SuperDrive, sold for $1,299. Finally, a high-end model shipped in a black case (the first black Apple portable in more than five years). It improved upon the middle-end model with an 80 GB hard drive, and sold for $1,499. All models were replaced in November 2006 by the Mac Book (Late 2006).

Announced in January 2006, the MacBook Pro was the first portable Mac to use Intel Processors. The name for Apple’s professional portable was ostensibly changed from PowerBook because Apple felt that all Macintoshes should have “Mac” in their product names, but was probably chosen because the Mac Book Pro no longer used a PowerPC processor—Though the PowerBook name predates the use of PowerPC processors, it was used in the naming of the Power Macintosh line to differentiate it from the previous 68k Macs.

Though the MacBook Pro included a number of enhancements to the final iteration of the PowerBook G4—a thinner case, a built-in iSight camera, a remote control with Apple’s Front Row home media center software, an ExpressCard/34 slot, improved wireless reception, a larger screen and the new “MagSafe” power connector designed to be less prone to damage—there were also some notable omissions. The MacBook Pro no longer included FireWire800, s-video or modem ports (a USB modem was available separately), and the slot-loading SuperDrive no longer supported dual-layer DVD+R media. Though it shipped with a Serial-ATA bus, the hard drive capacity was reduced from 120 GB to 80 or 100 GB.

The big news, however, was that the MacBook Pro included a dual-core processor, a first for an Apple portable. Though announced at 1.67 and 1.83 GHz, the MacBook Pro actually shipped with 1.83 or 2.0 GHz Intel Core Duo processors, with a 2.16 GHz processor available as a BTO option. The MacBook Pro shipped in two configurations: 1.83 GHz/80 GB/$1999 and 2.0 GHz/100 GB/$2499. Both configurations were speed-bumped in May 2006 to 2.0 GHz and 2.16 GHz, respectively, and were made available with a glossy screen as a BTO option. It was replaced in October 2006 by the Mac Book Pro (Late 2006).
