iPad 2 Review



Apple Inc  recently launched the second generation iPad called the iPad 2 or better known as the “Tablet Computer” on March 2, 2011. It was made available online in the US markets on March 11, 2011. And it was launched in 25 other countries on the 25th of the same month. The  high-tech iPad 2 is manufactured by Foxconn, which has an ongoing contract with Apple Inc.
What exactly is this ?
Apple iPad 2 is mainly designed to play audio music. It has built-in speakers and its output frequency ranges from 20 to 20,000 hertz. When connected with the help of an Apple Digital Adaptor, it gives a Dolby Digital Stereo effect or in other words up to 5.1 pure surround sound.
The other significant addition in the iPad 2 is the VGA front-facing and 720p rear-facing cameras with FaceTime video calling. It is this addition that makes it very attractive to most buyers. Another prominent feature of the iPad 2 is its new dual core Apple A5 processor. Although not designed to use as a mobile phone, a user with the help of a headset can make calls around the Wi-Fi environment using a VoiP application. This option is a real hit with a lot of the buyers.
The battery used is lithium-polymer and which lasts for up to 10 hours. In spite of its speed and enhanced graphics, there is little or no change in the life of its battery. The iPad 2 battery’s long life is one of the product’s main selling points.
Software and Hardware
The software used in Apple iPad 2 is iOS 4.3.1. However, a newer version 4.3.2 is available online.  The hardware used is a new A5 dual core processor with both front and rear cameras along with a 3 axis gyroscope. Many components are reduced in size and shape so as to fit into the new iPad. Apple iPad 2 runs up to twice as fast than its predecessor and graphics performance is nearly nine times faster.

Features
Its storage capacity is 32 GB or 64 GB and its RAM capacity is 512 MB DDR2. The size of the display unit is 9.7 inches with the graphics quality up to 2 Giga pixels.  The salient features are the multi-touch, touch screen, controls in the headset, light sensors, microphone, 3-way gyroscope, magnetometer, accelerometer and micro sim-card tray.
The dimensions of the iPad 2 are 241 mm in height, 186 mm in width, 8.8 mm depth. This makes it the sleekest looking tablet computer on the market. The weight of this model is 610 g or 1.34 lb which is a difference in weight of 100 grams in comparison with its predecessor.
Accessories
Its sleek outer shell has a new “smart cover” that removes any smears. The smart cover has three folds which magnetically sticks to the front and helps it to create a stand so as to make typing easy and watching movies in upright position. To make it more attractive, it has over 65,000 apps, which run faster because of the A5 processor. This gives it a tremendous head start over any competition.
Customer Reviews
The average customer review varies from 4.5 to 5 out of 5 stars.
Customers view the iPad 2 as a slim piece of cake, available in the smallest size with multi functions and incredible audio effects. In short, most, if not all of the buyers are fascinated at the slimness of the iPad.  The slimness of iPad 2 with its rounded edges makes holding easier and is more comfortable to hold the new iPad instead of its predecessor. Customers are thrilled by the Digital Dolby stereo and they feel it is absolutely fantastic.
The mobile phone feature has also given an enormous satisfaction to customers.
Customers estimate that the average sales of iPad 2 for 2011 would be around 35 million. In other words, there was no need for Apple to launch a second generation iPad as its predecessor already has around 80% of the US tablet market.
Some of the customers however feel that its screen resolution and photo quality can improve a bit and it could do with a USB port.
Price Review
Apple offers both white and black versions of the iPad 2 and its base model is priced at $500, which comes with 16GB of storage space and a Wi-Fi connection. However, if you are the tablet geek and require more storage-space for all your apps, photos, movies, videos and music then you can go in for 32GB model which is priced at $600 or the 64GB model which is priced at $700.

The iPad 2 offers a number of additional features in comparison to its earlier version. It’s hard to find any shortcomings or flaws with the iPad 2. Hence my advice is that if you can afford it – go for it, as you sure won’t regret it!

    best inventions of Steve Jobs


    10 finest products from Apple that changed the definition of computers and technology in this sector.
    It has been barely a few hours since Steve Jobs announced his resignation as cheif executive of Apple Inc ending his 14-year reign at the technology giant he co-founded in a garage.
    Even as Apple shares dived seven per cent in after-hours trade, few industry watchers are worried. Because what Steve Jobs created can probably never be destroyed.
    Last month, we'd published an article about the ten greatest Apple inventions. Today, we are republishing this article and looking back at Jobs' legacy.
    Today's Apple machines are small enough to fit into your pockets but it never started like that. About more than 25 years before when Apple's first iconic status machine was released it was like the invention of wheel to cave men. Here's a sneak-peek into 10 best Apple machines of all time.
    1. The Macintosh of 1984
    Macintosh 1984



    This was the original Mac machine to have all-in-one compact design along with innovative mouse and its graphical user interface (GUI) that was user-friendly. The Mac PC of 1984 changed the computer industry. It made things convenient for users.
    In the early 1980s PCs were controlled through text commands exclusively. First time in 1983 Apple launched a GUI named Lisa, but it was heavily priced at $9,995. This machine failed to capture the attention of people.
    In 1983 Mac was released at much cheaper price. At $2,495 it attracted everyone even who did not know or wish to learn cryptic command-line language. It had 128KB RAM and 8MHz processor.
    2. The PowerBook 100 series of 1991
    PowerBook 100 series 1991



    Apple launched a new series of portable line-up in 1991 that included PowerBook 100, 140 and 170. It was a joint venture with Sony and featured 10-inch monochrome screen. The three models became the blueprint for all subsequent laptops in terms of designs.
    The earlier edition of portable Macintosh called Macintosh Portable weighed 7.2kg. It was not so portable but introduced trackball to mobile computing. The PowerBook series placed keyboard towards the screen so that users get the comfort of resting their palms.
    It also placed the trackball in the centre of the palm rest which was earlier at the side. It became so popular that in the first year it brought $1 billion revenue to Apple.
    3. The Power Mac G3 of 1997
    Power Mac G3 1997

    This Apple machine represented a new beginning for the company. After the return of CEO Steve Jobs, Power Macintosh G3 was the first computer released. He then slashed to few core products from dozens in the product line and also cancelled cloning licences of the company with third-party manufacturers.
    Power Mac G3 took forward Apple in using industry-standard components in order to bring down the cost of its machines. The G3 chip of Motorola gave an improved performance and also used far less power than the earlier chipsets.
    The machine came at 233MHz chip speed. Until the introduction of G4 processor, the G3 chip set was the foundation for all computer lineup of Apple.
    4. The iMac of 1998
    iMac 1998

    iMac reversed the fortunes of Apple, as many pundits claim. It found a place on the desks of consumer and in pop-culture history with its playful colours and distinctive looks. It featured G3 processor but had no legacy ports.
    Moreover, it relied on Universal Serial Bus, which is technology offering plug-and-play ease for hot-swappable capabilities and connecting peripherals.
    iMac became the first machine to drop the floppy drives support. It was priced at $1,299.
    5. The PowerBook G3 'Wallstreet' of 1998
    PowerBook G3 'Wallstreet' 1998

    Wallstreet was the second generation portable lineup of Apple with its sleek shape and featuring G3 chipset. It had 14.1-inch screen, optical drives, two docking bays to hold batteries etc. It became instant classic.
    The Pismo version of Wallstreet released in February was much lighter and thinner in shape. It had FireWire 400 port and AirPort wireless networking.
    6. The iBook of 1999
    iBook 1999

    The iBook G3 brought back the G3 chip. Similar to iMac, the iBook also ditched all legacy ports for USB and it had a handle. It was the first laptop of Apple to come without a latch and also shipped with circular wireless charger.
    One thing to take note of here is it was the first-ever mainstream
    7. The Power Mac G4 Cube of 2000
    Power Mac G4 Cube 2000

    Power Mac G4 Cube was the most controversial release of Apple but it also deserves to be listed as one of the greatest machines of the company. It had bagged several design awards and also found a place at the Museum of Modern Art.
    The machine stood on 8-inch cube of technology suspended in a 10-inch clear acrylic enclosure. It relied on vertical optical drive and had touch sensor. The internals of the machine was cooled with the help of convection currents. The warm air relased from the top vent pulled cool air through the bottom and the acrylic's rear openings.
    Using G4 processor, it was the most compact desktop of Apple then. Its high price made people just to look at it but not to buy.
    8. The (Intel-based) iMac of 2006
    iMac 2006



    Before the launch of Intel-based iMac, Apple announced that it was about to leave the PowerPC architecture and move towards Core Duo processor platform from Intel. The company added that this change would enable thinner engineering and more powerful computers.
    It was January 10, 2006 when Apple made an announcement at Macworld Expo that the new arriving iMac will become the first Apple desktop with Intel chipset.
    Apple facilitated in it the running of Windows either virtually with third-party software or with the software of Apple Boot Camp. Hence, it has given the businesses and users a safety net if they want to switch away from PCs to Macs.
    9. The iPhone/iPod touch of 2007
    iPhone/iPod Touch 2007

    Technically it cannot be called a Mac, but its ultra-portable run had stripped-down several versions of Mac OS X. It made Macs small enough to fit in the pockets.
    After its announcement in 2007 at Macworld Expo, the iPhone took the mobile world by storm. Many of its features such as the Core Animation were not available on the desktop version of Mac OS X. The iPhone did the same to the mobile industry as the original Macintosh machine did to computer industry.
    With successive updates of iPhone software and its cousin the iPod touch, the machines gained more stability and more features. The thousands of available applications from App Store gave it the name of a true platform.
    10. The MacBook Air of 2008
    MacBook Air 2008

    The original MacBook Air had no built-in optical drive, no FireWire ports, no expansion card slots, and also had only one USB port. Keeping these aside, the Air was the first Mac machine which featured optional solid-state hard drive along with a special Intel design processor in both 1.6GHz and 1.8GHz model.
    The MacBook Air had 13-inch screen giving room for full-size keyboard comfort typing. It also had new and larger trackpad to support multi-touch capabilities.
    These are the finest products from Apple which changed the definition of computers and technology on this sector.

    Success story of Steve Jobs

    From a college dropout to heading an over $350 billion Apple empire, Steve Jobs dramatically transformed the worlds of personal computing, music and mobile phones, ushering in a new digital era.

    Jobs, who died on Wednesday at the age of 56 after a seven-year battle with pancreatic cancer, was also the man behind the stupendous success of the computer animation firm Pixar, makers of Toy Story and Finding Nemo.

    Though he himself never designed a computer in his life, it was because of him that the Apple products, while largely providing the same services as those from other companies, are perceived to be different. 



    Steve Jobs stands under a photo of him and Apple-co founder Steve Wozniak, January 27, 2010.




    Born on February 24, 1955 to Joanne Carole Schieble and Abdulfattah Jandali, Steven Paul Jobs was adopted by Paul and Clara Jobs. Jandali was a graduate student from Syria who later became a political science professor.

    Paul Jobs, who worked in finance and real estate before moving back to his original trade as machinist, moved his family down the San Francisco Peninsula to Mountain View and then to Los Altos in the 1960s.

    From an early age, Steve Jobs was interested in electronics. As an eighth grader, after discovering that a crucial part was missing from a frequency counter he was assembling, he telephoned William Hewlett, the co-founder of Hewlett-Packard. 



    Hewlett spoke with the boy for 20 minutes, prepared a bag of parts for him to pick up and offered him a job as a summer intern, according toThe New York Times.

    Jobs met Stephan Wozniak, with whom he co-founded Apple in 1976, while attending Homestead High School in neighbouring Cupertino.

    After enrolling at Reed College in 1972, Jobs left after one semester, but remained in Portland for another 18 months auditing classes. In a commencement address given at Stanford in 2005, Jobs said he had decided to leave college because it was consuming all of his parents' savings. 



    Jobs returned to Silicon Valley in 1974 and took a job as a technician at Atari, the video game manufacturer. But, he left after several months and travelled to India with a college friend, Daniel Kottke, who would later become an early Apple employee.

    Jobs returned to Atari and along with Wozniak, then working as an engineer at HP, began attending meetings of the Homebrew Computer Club, a hobbyist group that met at the Stanford Linear Accelerator Center in Menlo Park, California in 1975.



    Personal computing had been pioneered at research laboratories close to Stanford and was spreading. Wozniak designed the original Apple I computer simply to show it off to his friends at the Homebrew.

    It was Jobs who had the inspiration that it could be a commercial product. In early 1976, he and Wozniak, using their own money, began Apple in the Jobs family garage in Los Altos with an initial investment of $1,300 before securing the backing of former Intel executive A C Markkula, who lent them $250,000.

    Wozniak would be the technical half and Jobs the marketing half of the original Apple I Computer. 



    Shortly thereafter, they moved the company to a small office in Cupertino. Reacting to Jobs' demise, a Twitter user named Matt Galligan wrote: "R.I.P. Steve Jobs. You touched an ugly world of technology and made it beautiful."

    In April 1977, Jobs and Wozniak introduced Apple II at the West Coast Computer Faire in San Francisco, creating a sensation. The company went public in 1981, when its sales touched $600 million from $2 million in 1977.

    By 1983, Apple was in the Fortune 500, an achievement for a new firm. In 1981, Jobs joined a small group of Apple engineers pursuing a separate project, a lower-cost system code-named Macintosh, which was introduced in January 1984. 



    Jobs recruited John Sculley as Apple's chief executive in 1983. Sculley, a former Pepsi-Cola chief executive, helped Jobs introduce a number of new computer models, including an advanced version of the Apple II and later the Lisa and Macintosh desktop computers.

    But, the two men became estranged and a power struggle ensued when the Lisa failed commercially and early Macintosh sales proved disappointing, leading to Jobs losing control of the Lisa project.

    The Apple board ultimately removed Jobs from his operational role and 1,200 Apple employees were laid off. Jobs then left Apple in 1985. 



    Jobs holds up Apple's Mini Mac computer on January 11, 2005.


    "I don't wear the right kind of pants to run this company," he told a small gathering of Apple employees before he left, a member of the original Macintosh development team was quoted as saying by NYT.

    He was barefoot as he spoke, and wearing blue jeans. In September that year, he announced a new venture NeXT Inc.

    He also established a personal philanthropic foundation after leaving Apple but soon decided, instead, to spend much of his fortune $10 million on acquiring Pixar, a struggling graphics supercomputing firm owned by filmmaker George Lucas. 



    The purchase, though a significant gamble as there was little market then for computer-animated movies, proved profitable when the company, in 1995, along with Walt Disney Pictures, released 'Toy Story', collecting box-office receipts of $362 million.

    When Pixar went public in a record-breaking offering, Jobs became a billionaire.

    In 2006, the Walt Disney Company agreed to purchase Pixar for $7.4 billion, making Jobs its largest single shareholder, with about 7 per cent of the firm's stock. 



    Steve Jobs makes a joke about his blood pressure after introducing the MacBook laptop.


    Meanwhile, Apple, after unsuccessful efforts to develop next-generation operating systems in 1996 with Gilbert Amelio in command, acquired NeXT for $430 million.

    The next year, Jobs returned to Apple as an adviser and became its chief executive again in 2000.

    With his rise, Jobs personal life also became more public. He had a number of well-publicised romantic relationships, including one with folk singer Joan Baez before he married Laurene Powell. Jobs and Laurene had three children -- two daughters Eve Jobs and Erin Sienna Jobs and a son, Reed.

    Jobs had one more daughter, Lisa Brennan-Jobs, from a relationship with Chrisann Brennan.

    C++ Interview questions and answer

    C++ Interview questions and answers
    Define structured programming.
    Structured programming techniques use functions or subroutines to organize the programming
    code. The programming purpose is broken into smaller pieces and organized together using
    function. This technique provides cleaner code and simplifies maintaining the program. Each
    function has its own identity and isolated from other, thus change in one function doesnít affect
    other.
    Explain Object oriented programming.
    Object oriented programming uses objects to design applications. This technique is designed to
    isolate data. The data and the functions that operate on the data are combined into single unit.
    This unit is called an object. Each object can have properties and member functions. You can call
    member function to access data of an object. It is based on several techniques like
    encapsulation, modularity, polymorphism, and inheritance

    Google+ vs Facebook






    It is three weeks old and still not out of the labs but Google+ already boasts over 10 million users. What's drawing in the new fans? 


    Unabashed imitation of Facebook's key inventions and a clutch of great innovations of its own. 


    Here's a feature by feature comparison of the newest social networking rivals. 


    Posts vs Wall 
    /photo.cms?msid=9253368
    /photo.cms?msid=9253369






    A blatant copy: G+ posts are styled like FB's except one addition: you can disable reposts (they're like retweets) and comments right there. 


    Stream vs News Feed 
    /photo.cms?msid=9253402
    /photo.cms?msid=9253403




    Remove the signature Facebook Blue and you can't tell Stream from Feed. Imitation is the best form of flattery. Or maybe an admission Google couldn't think better? 


    Circles vs Lists 
    /photo.cms?msid=9253420
    /photo.cms?msid=9253422




    A winner for G+. 'Circles' are groups to categorise people you know and share posts, feeds or photos exclusively. Basic Circles like 'Friends' and 'Family' are preloaded but you can create your own. (Think 'work monsters'). Compared with this, FB's Lists is plain boring. 


    Hangout vs Video call 
    /photo.cms?msid=9253457
    /photo.cms?msid=9253461




    The cracker. Hangout allows up to 10 people to video chat together. Tiny feeds of buddies line up the bottom of your screen with a big image of the person talking. There's a window for text chats and a button for watching YouTube . FB's latest one-on-one video chat just doesn't make the cut. 


    +1 vs Like 
    /photo.cms?msid=9253482
    /photo.cms?msid=9253484




    There is something about saying I 'Like' that just isn't in I '+1'. But Google is using it to make its search social too. 
    /photo.cms?msid=9253506

    /photo.cms?msid=9253519
