Follow the Simple Steps to develop the iPhone App and Submit it to App Store

It is not as hard or as simple to develop an iPhone App that one might think. As many people have misconception that iPhone Application development is really very hard, I want to remove this conception and motivate them to go for it by following the steps mentioned in the article below.
“Cooking” up an iPhone application also involves a process similar to Cooking. You can find here the steps which should be followed from head to the bottom i.e. from an app idea to its upload on the iTunes.
It must be clear to you that creating an iPhone app or the iPhone application development is not entirely free; also you will need a Mac at some point and so need to use specific Mac-happy code to develop the application.

Microsoft Commptia A+ Training , Comptia A+ Certification and over 2000+
Exams with Life Time Access Membership at http://www.actualkey.com

Are you excited now? Follow these exhilarating steps:
1. Design a Smart and Unique Idea

Think of a unique idea and craft the design in a way that one want to use your app. Develop the app in a way that people can pay you for that as they will get more in return of their money.

Please cross check about your idea in the app store that there is no app having the same idea. If you found one, go for a better app which already exists.

2. Get a Mac and Register on Apple as an Developer
As the iPhone development tools are available only for Mac Users, so it is necessary to get a Mac to have your app in the App Store. Mac mini will also serve the purpose.

After having a Mac, go for the free registration to become an official Apple Developer by providing them with your details and agreeing to their terms. Only once the registration is needed. After registration, you can develop iPhone apps for any of the Mac products.

3. Download iPhone Software Development Kit (SDK) and XCODE

Now you are an Official Apple Developer, you are allowed to download iPhone SDK. As SDK comes with all types of documents, sample codes and all the other things you might need later. So, the download is HUGE, and so will take a few hours. Do take care of its version, as it depends on the OS you are using.

As per Apple, “XCode is a complete, full-featured IDE built around a smooth workflow that integrates the editing of source code, with the build and compile steps, through to a graphical debugging experience – all without leaving the view of your source code.” So, go for this and download it.

4. Use the Templates in SDK for iPhone Application development
Start designing the app with the templates available in the SDK. In the SDK, you can find lot of templates to choose one from and also have great You tube clip tutorials to tell you how to use these templates effectively.
5. Program your App using Objective-C

Understand the basics of Objective-C and program your app. You can take screenshots as you precede that helps you remember what you tried. Time required by the apps totally depends on the app features and the details you want in it.

6. Test the application

Make the full use of the huge download of SDK you have done. SDK comes with a lovely iPhone simulator, load your app in it and test it on the simulator. Use the app in all the possible ways one can use and try to work out as many bugs as you can. Test it completely.

7. Upload the iPhone application on iTunes for Approval

Loading an app into iTunes costs a one time member fee of $99 (USD), and it is must to be paid. There is no way to get away of this amount. But, if your app is worthy, you can earn it back in many folds.

Test your App completely and work on all the issues and then submit for approval. Apple takes few days to approve it so be patient and wait for the response.

Major Symantec breach highlights risks of running old software

Symantec says it has fewer than 50,000 users of pcAnywhere, a remote-access program that has been around for decades. It now says, for safety’s sake, those users should pull the plug. Immediately.

Best comptia A+ Training, Comptia A+ Certification at Certkingdom.com

PCAnywhere was ancient in June 1996, when Symantec shipped pcAnywhere 7.5 for Windows 95 and Windows NT Workstation 4.0. That’s the oldest press release I can find online, and it’s introducing version 7.5. The product already had seven releases at the dawn of the Windows era. And the software industry didn’t run at Internet speed back then.

People are still using versions even older than that. I am pretty sure the MS-DOS version of the remote-access program goes back to the late 1980s. And yet I found a support request on Symantec’s forums from May 2010—less than two years ago—from someone who needed to connect to a computer running MS-DOS 6.22 and PC Anywhere 5.0 for DOS.

This was well into the 21st Century.

pcAnywhere version 12.0 shipped in 2006. It’s had incremental releases since then, but Symantec hasn’t found any of those events important enough to issue a press release.

Let’s paint this picture in stark black and white: This is a six-year-old software program, built on decades of legacy code written in pre-Internet days, that is now in maintenance mode. Or, if you prefer, on life support.

And now Symantec is urging its users to pull the plug, at least temporarily. The company revealed the gory details this morning not in a press release, but in a 10-page white paper (PDF):

Upon investigation of the claims made by Anonymous regarding source code disclosure, Symantec believes that the disclosure was the result of a theft of source code that occurred in 2006. We believe that source code for the 2006-era versions of the following products was exposed: Norton Antivirus Corporate Edition; Norton Internet Security; Norton SystemWorks (Norton Utilities and Norton GoBack); and pcAnywhere.

I wouldn’t be worried about those antivirus and security programs. They have been regularly updated and heavily rearchitected since 2006, with significant upgrades every year. But pcAnywhere has been in maintenance mode, a forgotten product.

Symantec says fewer than 50,000 people are still using pcAnywhere. And now the company says, in no uncertain terms, they should stop:

With this incident pcAnywhere customers have increased risk. Malicious users with access to the source code have an increased ability to identify vulnerabilities and build new exploits. Additionally, customers that are not following general security best practices are susceptible to man-in-the-middle attacks which can reveal authentication and session information. General security best practices include endpoint, network, remote access, and physical security, as well as configuring pcAnywhere in a way that minimizes potential risks.

At this time, Symantec recommends disabling the product until Symantec releases a final set of software updates that resolve currently known vulnerability risks. For customers that require pcAnywhere for business critical purposes, it is recommended that customers understand the current risks, ensure pcAnywhere 12.5 is installed, apply all relevant patches as they are released, and follow the general security best practices discussed herein. [emphasis added]

I am not sure I have ever heard of a company advising its customers to stop using a product completely because it was too dangerous. But apparently the risk with pcAnywhere is so great that this is the only sane option.

There are many, many modern alternatives to allow secure external access to your business network or your home PC. If you’ve been hanging on to pcAnywhere, you’re now officially out of excuses to switch.

Update: Reached for comment, a Symantec spokesperson replied vie e-mail with a statement that repeated, almost word for word, the advice contained in the white-paper advisory. The spokesperson also referred customers to a Symantec site that hosts information on the breach:

Universal Serial Bus (USB) is a high speed bus standard developed by Compaq, IBM, DEC, Intel,
Microsoft, NEC, and Northern Telecom. It provides the Plug and Play capability of Windows to
external hardware devices. USB supports hot plugging, which means that a USB device can be
installed or removed while the computer is running. A single USB port can be used to connect up to
127 peripheral devices, such as CD-ROM drives, tape drives, keyboards, scanners etc. USB 1.1
has a maximum data transfer rate of 12 Mbps, whereas USB 2.0 has a maximum data transfer
rate of 480 Mbps. USB 2.0 is fully backward compatible with USB 1.1.

QUESTION 6
Which of the following features are related to power management?
Each correct answer represents a complete solution. Choose two.

A. Hot plugging
B. Hibernate mode
C. Standby mode
D. Safe mode

Answer: B,C

Explanation:
The Hibernate mode and Standby mode are features related to power management.
Hibernate mode is a power saving feature for computers. In hibernate mode, the current state of a
computer is saved to the hard disk, and the computer shuts down. A user will have to power on
the computer to restore the previous settings. When a computer resumes from hibernate mode, it
reads the saved settings from the disk and restores the system state as it was before it entered
hibernate mode. By default, hibernate mode is disabled. If a computer is not ACPI-enabled or
APM-enabled, users will have to enter hibernate mode manually. Users cannot set the computer
to automatically hibernate after a certain time. With ACPI-enabled and APM-enabled computers,
users are able to set hibernate mode automatically.
The standby mode is a power saving feature for computers. In this mode, a computer does not
shut down completely. The computer goes to low power state and, as a result, it consumes less
power.
When the computer resumes from the standby mode, full power is restored to its devices. During
the standby mode, if the power supply is disconnected or interrupted, data might be lost. The
standby mode is available automatically on ACPI-enabled or APM-enabled computers. Users do
not need to enable this mode manually. This mode is not available in non-ACPI and non-APM
based computers.
Answer option A is incorrect. Hot plugging is a feature in which a device can be installed or
removed while the computer is running.
Answer option D is incorrect. Safe Mode is a Windows feature used to start a computer with basic
drivers, such as mouse, keyboard, etc. It bypasses blocking issues, such as system corruption, or
installation of incompatible drivers or system services, enabling the Administrator to resolve such
issues.

QUESTION 7
Which of the following are types of LCD monitors?
Each correct answer represents a complete solution. Choose two.

A. SVGA
B. Active Matrix
C. Passive Matrix
D. X-Matrix

Answer: B,C

Explanation:
Two types of LCDs are available.
Active matrix
Passive matrix
Active matrix LCDs uses individual transistors to control each pixel on the screen. This type of
LCD consumes more power but provides sharper images than the passive matrix LCD. Passive
matrix Passive matrix screens do not refresh quickly to rapid changes. The passive matrix screen
displays weak colors. LCDs consume less power and are cheaper than Active matrix LCDs.
Answer option A is incorrect. SVGA is a type of CRT monitor used with the Desktop computers,
and not the LCD monitor.
Answer option D is incorrect. There is no LCD display type such as X-Matrix.

QUESTION 8
Which of the following transmits all ATSC HDTV standards and supports 8-channel digital audio?

A. DVI
B. S-Video
C. SVGA
D. HDMI

Answer: D

Explanation:
HDMI stands for High-Definition Multimedia Interface. It is a standard, uncompressed, and alldigital
audio/video interface. HDMI is capable of delivering the highest quality digital video and
multichannel digital audio on a single cable. It provides an interface between any audio/video
sources, such as a DVD player or a computer and a digital television (DTV) or video monitor.
HDMI transmits all ATSC HDTV standards and supports 8-channel digital audio, with extra
bandwidth to accommodate future enhancements. HDMI has two types of connectors. Type A and
Type B. Type A and Type B connectors use 19 pins and 29 pins, respectively. The Type B
connector is designed for very high-resolution displays that are expected in near future.
Answer option B is incorrect. S-Video, also known as Y/C video, stands for Super-Video. It is a
technology for video transmission. Using this technology, the video is transmitted into two
separate signals. One is used for color, and the other for brightness. Sometimes S-Video signals
are considered as a type of component video signal. However, its quality is inferior to other
complex component video schemes such as RGB. This technology produces sharper images than
those produced by composite video, which carries the entire set of signals in a single line. For
using SVideo, the device sending the signal must support S-Video output and the device receiving
the signal needs to have an S-Video input jack.
Answer option A is incorrect. DVI stands for Digital Visual Interface. It is a standard for high speed,
high resolution digital display invented by
Digital Display Working Group (DDWG). DVI accommodates analog and digital interfaces with a
single connector. New video cards have DVI as well as VGA ports built into them. Most of LCD
monitors come with a 15-pin VGA connection cable, even if they are capable of handling digital
signals coming from DVI connections. However, some monitors come with both types of cables.
DVI has three main categories of connectors. They are. DVI-A, DVI-D, and DVI-I. DVI-A is an
analog-only connector, DVI-D is a digital-only connector, and DVI-I is an analog/digital connector.
DVI-D and DVI-I connectors are of two types. single link and dual link. DVI supports UXGA and
HDTV with a single set of links.
Higher resolutions such as 1920 x 1080, 2048 x 1536, or more can be supported with dual links.
Answer option C is incorrect. A VGA or SVGA connector is a 15-pin, three rows, female connector,
on the back of a PC used for connecting monitors. Reference. "http.//en.wikipedia.org/wiki/High-
Definition_Multimedia_Interface"

D. AGP

Answer: B

Explanation:
PCMCIA is a widely used expansion card slot for laptops.
What is PCMCIA card? Personal Computer Memory Card International Association (PCMCIA)
card is also known as PC card.
The PC card uses a small expansion slot and is primarily used in laptops. However, PC cards are
also available in some of the desktop computers. There are three types of PCMCIA cards.
1.Type I
2.Type II
3.Type III
Answer option C is incorrect. PCI slots are used in PC's, not laptops.
Answer option D is incorrect. AGP is a legacy graphics slot for PC's.
What is AGP (Accelerated Graphics Port)?
AGP is a high speed 32-bit bus designed for high performance graphics and video support. It
allows a video card to have direct access to a computer's RAM, which enables fast video
performance. AGP provides a bandwidth of up to 2,133 MB/second.

Mozilla touts Firefox impact in SOPA blackout

Mozilla yesterday extolled the impact of its 12-hour participation in Wednesday's anti-SOPA strike, saying Firefox users and fans generated over a third-of-a-million emails to the U.S. Congress.

Best comptia A+ Training, Comptia A+ Certification at Certkingdom.com

Two days ago, Mozilla blackened Firefox's default home page and redirected its websites to an "action page" asking users to contact their federal representatives and voice their opposition to "Internet blacklist legislation."

Mozilla joined other websites, including Craigslist, Google and Wikipedia, in a one-day "virtual strike" to drum up resistance to the Stop Online Piracy Act (SOPA) and the Protect IP Act (PIPA), bills being considered by the U.S. House of Representatives and the Senate, respectively.

Since Wednesday's blackout, Washington politicians have backpedaled on the legislation. Today, Senate Majority Leader Harry Reid (D-Nev.) postponed next week's vote on PIPA, while Rep. Lamar Smith (R-Texas), chairman of the House Judiciary Committee, said the committee was also postponing action "until there is wider agreement on a solution."

According to Mozilla, Firefox users were instrumental in getting the message to Congress.

"Ultimately, 360,000 emails were sent by Mozillians to members of Congress, contributing a third of all the emails generated by EFF's campaign site," said Mozilla in a blog post Thursday.

Both the revised Firefox home page and the special action page offered users a button that led them to a page hosted by the Electronic Frontier Foundation (EFF), a San Francisco-based Internet rights advocacy group. The EFF page provided a way for visitors to quickly email their House and Senate representatives.

More than half of the people who reached the EFF page from Firefox or Mozilla's websites fired off emails to Congress.

In a separate statement today, the EFF said it had helped users send about 1 million emails.

Mozilla also said approximately 30 million people in the U.S. saw the darkened Firefox home page in their browser, and that 1.8 million visited the open-source organization's own SOPA information and action page.

Mozilla's contribution to the anti-SOPA drive was small potatoes compared to Google's: The search giant, which reportedly signed a deal with Mozilla that guarantees the latter $300 millionannually for sticking with Google on the Firefox home page, collected over 7 million signatures Wednesday on its own online petition.

Avaya SMB collaboration platform gets robust new mobile client

Android and Apple iPhone devices will get a richer conferencing and unified communications experience with Avaya IP Office 8.0.

Microsoft Avaya Exam Training , Avaya Certification and over 2000+
Exams with Life Time Access Membership at http://www.actualkey.com

The latest version of Avaya’s unified communications platform for small and midsize businesses boasts two major changes: a robust mobile application and the ability to integrate communications features into certain key business applications.

The mobile component of Avaya IP Office 8.0 is called one-X Mobile Preferred for IP Office. Initially available for Android devices (Apple iPhone is coming soon), the application allows users to manage who is on a conference call — allowing them to invite, view, mute or drop participants. The mobile application is recognized by the IP Office presence application, so that people can tell when you are available or shouldn’t be disturbed. There also is a “geopresence” feature that broadcasts where someone is located. (Part of me can see the usefulness of this feature, but it also smacks a little bit of employee babysitting.)

one-X Mobile Preferred is an extension of Avaya’s Essential Mobility technology.

The other major enhancement to Avaya’s latest SMB unified communications platform update comes in the form of new plug-ins to widely used business productivity applications. For example, small businesses can use the Avaya platform to make or receive a call from within a Salesforce.com page; they can also go to a single location to view Google Talk and IP Office contact lists.

Opinion: How Apple has changed enterprise computing, forever

Led by the fast-emerging BYOD (Bring Your Own Device) trend, Apple [AAPL] is crunching into the enterprise market, creating a growing market share with the Trojan Horse of its mobile devices and a fast-growing interest in its Macs.

We need promises that deliver

With Windows 8 the latest Microsoft promise to woo the corporate markets, this is a time of decision. Many enterprise-class tech purchasers are looking at whether it's worth upgrading to the next MSFT OS on strength of the firm's mobile-meets-PC promise, or whether to take on any of the two main alternatives for this dream you see around today: Apple or Android.

Despite my reservations concerning Google's moral prerogative when it comes to the way it created Android (I'm an Apple Holic and do feel the feeling of betrayal between Apple and Google has some good reasons to run deep) it must be said that in conjunction with iOS and OS X, these two big firms have freed the enterprise world from the rubber-clad silvery handcuffs of the Microsoft-based hegemony. And the latter firm's CEO, Steve Ballmer, has been unable to crack the whip to preserve the firm's control of the corporate world.

Evidence-based dreaming

This isn't just a pipe dream. Think on this:

-- A UK YouGov survey recently claimed iPad usage in business has doubled in the last year.
-- An Aberdeen Group survey points out that 96 percent of businesses have at least one iPad in use.
-- SAP now has at least 3,300 corporate--owned iPhones and over 11,000 iPads -- a move which has reduced tech spend by a significant amount.

That's just Apple's ecosystem. Google still has work to do to deliver a truly credible alternative to Cupertino's lead -- there's over 500 samples of Android OS malware in the market, with Websense predicting this will rise to "thousands" this year. What does that mean?

It means that at this stage, faced with a choice between re-investment in Windows 8 and the subsequent investment in PC upgrade for machines capable of running that OS, or a move to the credible and secure Apple ecosystem, tech buyers face a truly credible choice for the first time in years.

I said, evidence-based

And this is happening. Recent Gartner and IDC figures show a huge slump in the PC market worldwide -- but also reveals that Mac sales continue to climb, delivering Apple a PC marketshare in excess of 10 percent for the first time in years. I can still recall a time when critics, trolls and naysayers said this would never happen. A note to them: it did.

So what's next? I'm not arguing Apple will ever take over the enterprise, but it must be true to say that true security comes from not being 100 percent dependent on any one OS or computing platform. It makes the chosen platform too attractive to malware-makers: check out the domestic users with broken, virus-laden PCs they can't afford to fix as evidence of this.

The future of enterprise tech will not be Microsoft's. Instead the future will consist of heterogeneous collections of mixed-platforms. This will benefit everyone. Business will gain a more stable work environment. Consumers will benefit from their data shared with and within enterprises being safer than before -- at least, they will in the event enterprise users get it together to make the right decisions to ensure rock-solid security across all platforms.

Make good decisions, please

Virtual Private Networks; App installation policies; usage agreements for private devices on corporate networks; malware protection; fast software upgrades and switched-on, flexible disaster management policies will be among the topics which will matter deeply to business IT planners.

The danger is that in the event the wrong choices are made, then the promise of a global, heterogeneous and secure computing environment could be undermined.

Assuming these questions are resolved, then it's clearly arguable to say that, since 1997, Apple has ably fought back, disrupting not just the MP3 player, digital music, mobile and tablet markets, but also the enterprise sector.

Smart education

Intelligence led its decisions. Rather than compete directly, brandishing its cutlass of platform superiority, Apple achieved this PC tech revolution not through a frontal attack on Microsoft's hegemony, but through a focus on delivering the best devices out there, buoyed by the massive success of the iPad, iPhone and iPod.

Google acquires 200 more patents from IBM

Google has acquired over 200 more patents from IBM, adding to the 1,000 patents it bought from the technology giant last summer.

Best IBM Certification Training and IBM Exams Training and more Cisco exams log in to examkingdom.com

Google is ramping up its efforts to bolster its patent position, as it acquires 217 patents from technology giant IBM.

The patents range from server infrastructure technologies to mobile phones, databases and even self-driving cars; something the search giant has been venturing into in recent months.

Google acquired 187 patents and 36 patent-pending applications, adding to the 1,000 it bought off IBM in the summer. From the $12.5 billion Motorola Mobility purchase, the search giant will take 17,000 patents and over 7,000 patents-pending.

But it failed in its bid to acquire a crucial platter of 6,000 patents from bankrupt telecoms giant Nortel.

According to sister site ZDNet UK, the new IBM patents cover areas “pertinent to Android”, such as NFC-enabling technologies and availability policies on virtual machines.

The company continues to spend billions on its technology portfolio in efforts to fight off competitive action from its rivals.

In August, Google accused Apple and Microsoft amongst others of conspiring to attack its Android mobile operating system, saying they were waging a “hostile, organised campaign” of “bogus” patents to make Android more expensive.

Google’s acquisition plans of Motorola Mobility hit a roadblock late last year as European regulators suspended the review. While Google is “confident” that the proposed merger is good for competition, the European antitrust authority seeks the access of further documentation.

The patents alone are worth a goldmine to Google, rather than ‘what’ it can do with the smartphone maker.

Google is also embroiled in a legal spat with Oracle that is expected to go to trial later this year. It is alleged that Android technologies relating to Java infringe Oracle’s patents.

As Android remains in the limelight of global patent turf wars, Google continues the battle with its rivals and competitors in court.

It’s wake-up time for Google, as the company realises that it is late to the game. By bolstering its patent portfolio, it can not only have itself a nest egg for licenses but an additional layer of protection for its valuable mobile operating system from future attacks.

your knowledge about different issues involving the concepts associated
with the updated A+ exam (2009 Edition), which also includes topics on
Windows 7 and IPv6.
Who This Book Is For
If you have studied the content for both the 220-701 and 220-702 exam and feel
you are ready to put your knowledge to the test, but you are not sure that you
want to take the real exam yet, this book is for you! If you have answered other
practice questions or unsuccessfully taken the real exam, and want to do more
practice questions before going to take the real exam, this book is for you, too!
Even when the exam is done and you have passed with flying colors and have the
A+ certificate in your pocket, keep the book handy on your desktop to look for
answers to your everyday security issues.
What You Will Find in This Book
This book is all about practice questions! The practice questions in the book,
some very easy and others with a little complicated problem scenario, all are
intended to raise your confidence level before you take the real exam. You will
find questions that you will face in real life.
This book is organized according to the objectives published by CompTIA for

question. Use this information to learn why an answer is correct and to
reinforce the content in your mind for the exam day.
Note
It is not possible to reflect a real exam on a paper product. As mentioned earlier, the purpose
of the book is to help you prepare for the exam and not provide you with real exam
questions. Neither the author nor the publisher can guarantee that you will pass the exam
only by memorizing the practice questions given in this book.

Hints for Using This Book
Because this book is a paper practice product, you might want to complete your
exams on a separate piece of paper so that you can reuse the practice questions
again and again without having previous answers in your way. Also, a general
rule of thumb across all practice questions products is to make sure that you are
scoring in the high 80% to 90% range for all topics before attempting the real
exam. The higher percentages you score on practice question products, the better
your chances for passing the real exam. Of course, we cannot guarantee a
passing score on the real exam, but we can offer you plenty of opportunities to
practice and assess your knowledge level before you enter the real exam.
When you have completed the exam on paper, use the companion CD to take a
timed exam. This will further help you gain confidence and make a self-assessment
in case you need more study. Your results will indicate the exam objectives
in which you need further study or hands-on practice.
Need Further Study?
Are you having a hard time correctly answering these questions? If so, you probably
need further review of all exam objectives. Be sure to see the following sister
