Different Types of Mobile Phone Operating Systems?

There are many different mobile phone operating systems currently being used. Some of the most well-known include Symbian, BlackBerry OS, iOS, Windows Mobile, and Android. Most of them are associated with specific brands of phone made by specific companies while others are open-source and are available on a variety of platforms.

Symbian is primarily found on Nokia phones, but phones by Sharp, Fujitsu, Sony and other companies have the operating system installed as well. Symbian is open source, meaning anyone can use it without having to pay. It is widely used, but it is not the most advanced or full-featured of mobile phone operating systems. Most phones that use Symbian are low-end devices, not full-featured smart phones. Many manufacturers, including Nokia, who had long been the biggest supporter of the OS, have switched over to other operating systems.

One of the most well-known operating systems for mobile phones is the BlackBerry OS. It is the only one of the mobile phone operating systems to be found on BlackBerry devices. The BlackBerry OS is tailor-made for business, with functionality taking a seat over personality or appearance. Its main focus is on messaging, email and other communication features. Media players, and other entrainment-based applications are less-common for the device.

Apple's iOS is found on the iPhone, iPad and iPod Touch. Operating system security and compatibility has been a point of contention for some in regards to iOS. It is entirely closed-source, and Apple chooses on its own which software the platform will and will not support. Adobe Flash, for example, does not work on the embedded operating system. Still, it does have a wide variety of apps and an interface that many laud for its ease of use.

Windows Mobile, also known as Windows Phone, is the mobile phone version of Microsoft's operating system. Because of this, it is easily compatible with many Windows programs such as Microsoft Office, making it a popular choice for businesspeople. Windows Mobile was originally designed for Microsoft's line of Pocket PCs before being adapted for use in phones.

The Android is based off of the Linux operating system. Originally developed by an independent organization, it was later bought by Google, although the OS itself remains free and open source. Android is praised by many for his flexibility as a platform. Anyone can develop apps for the OS, and any company can release a phone using it.

There are just some of the mobile phone operating systems currently in use. Palm's webOS, bada from Samsung, and Noki's Maemo are just some of the operating systems that are used on smartphones around the world. Given the ever-changing nature of the technology industry, even more are bound to show up in time.

Standard Mobile Phone versus the Smart Phone

The standard mobile phone is your conventional cellular phone that is intended primarily for mobile communication: you can make and receive calls, send and receive SMS (Short Messaging Service) and MMS (Multimedia Messaging Service), store information and data (such as contacts, calendars, notes and memos, to-do lists, take pictures and record videos using your multi-megapixel camera (usually up to 5MP), organize files through simple file managers, have access to the world wide web via installed browsers, download and play music and games, and other limited mobile services (depending on the capabilities of your mobile phone). The features are very basic. Usually, your standard mobile phone will be equipped with either the numerical format keypad or the QWERTY keyboard. Memory cards can be added and inserted in the phone’s built in slots. Other advanced features will allow you access to Bluetooth technology for internet connectivity and file sharing services.

The smart phones, otherwise known as PDAs (Personal Digital Assistant) or Pocket PCs, are much more complicated devices compared to the basic mobile phone. They run on operating systems making your smart phones serve more like miniature computer systems rather than a simple phone unit. You can have office applications installed—word, power point, spreadsheets, etc. Your emails and other internet-based communications will be in sync. Anywhere you go, you can have access to your emails and social networking site accounts. There are a multitude of applications that you can download (or buy) into your Smartphone: from games to travel trackers to news updates to weather reports to finance management programs to dictionaries and references to live updates on twitter! The world is truly at the palm of your hand when you have a smart phone. Of course, the smart phone is generally more expensive and they come out in a lot more innovative designs. Touch screens has also become the trend among these highly-advanced mobile phones.

Smartphones of April 2013

Samsung Galaxy S4  - Rs 41,500


The latest from the Samsung Galaxy series
The latest device in the series brings with it some new additions to the TouchWiz UI, aiming to make the user experience that much more exciting. Housing Samsung’s new Exynos 5 Octa Processor (1.6GHz quad-core + 1.2GHz quad-core) to run Android Jelly Bean 4.2 and a slew of new features, Samsung’s well-priced S4 is already making big waves in the industry.





Here’s a quick look at the S4’s Specs:
  • 5-inch full HD Super AMOLED (1920 x 1080) display, 441 ppi
  • HSPA+, LTE, GPRS/EDGE
  • Wi-Fi 802.11 a/b/g/n/ac, dual-band, DLNA, Wi-Fi Direct, Wi-Fi hotspot
  • Bluetooth 4.0 with EDR and A2DP

  • 16GB internal storage with microSD card for further expansion up to 64GB
  • TV out via MHL
 
  

 HTC One - Rs. 42,900


The "One" to stand out?
 HTC’s latest flagship is simply called the "One". With a robust build and the latest edition of Sense UI, i.e. version 5.0, the One is proving to be a popular device since it’s launch earlier this month. Going with a Unibody design yet again, HTC has tried to re-invent its design form by going all metal and grilles galore. With a 1.7GHz quad-core processor powering it, a few new additions to the UI and an all-new camera tech dubbed UltraPixels, the One is a strong contender for this quarter's top smartphone. Of course, it’s competing with the Galaxy S4 for that position. Nevertheless, it’s got a lot to offer, including Beats Audio enhancement technology.
   The One also features:
  • 4.7-inch full HD Super LCD3 (1920 x 1080) display, 441 ppi
  • HSPA+, LTE, GPRS/EDGE
  • Wi-Fi 802.11 a/b/g/n/ac, dual-band, DLNA, Wi-Fi Direct, Wi-Fi hotspot
  • Bluetooth 4.0 with EDR and A2DP
  • GPS with A-GPS support and GLONASS
  • NFC
  • 4MP UltraPixel camera with LED flash, Simultaneous HD video and still image stabilisation, 1080p video recording.
  • 2MP front-facing camera, 1080p video recording @ 30fps
  • 16GB/32GB internal storage with microSD card for further expansion up to 64GB
  • FM radio
  • TV out via MHL
 

Xperia SP – Rs 27,490

The all-new Xperia SP – could it be worth the money?
Taking its cue from bigger brother, the Xperia Z, the SP is for those who want a similar experience but at a lower cost. The SP isn’t as fully loaded as the Z or ZL, but it does offer quite a bit of functionality for potential consumers. Powering it is a 1.7GHz dual-core processor for Android Jelly Bean 4.1. Sony, for some reason, has always been a little behind of the OS version and also issues updates a lot later than the competition. This could be a problem for the company even though its devices have being gaining popularity recently. Sony’s Mobile Bravia Engine should hopefully keep the display as vibrant as some of the others.
 

Here are the key specs of the Xperia SP:
  • 4.6-inch display with a 1280 x 720 pixel resolution
  • LTE, HSPA+, GPRS/EDGE
  • Wi-Fi 802.11 b/g/n, DLNA, Wi-Fi hotspot
  • Bluetooth 4.0 with A2DP
  • NFC
  • GPS with A-GPS support and GLONASS
  • 8MP primary camera with LED flash, 1080p video and VGA front-facing camera
  • 8GB internal storage, with microSD card slot
  • FM radio
  • TV Out via MHL

Nokia’s Lumia series is fast becoming a popular option among the masses, especially with the Lumia 620 and the recently launched 520 and 720. Their price tags put them in a very competitive position – offering high-end bodies with better than average specifications at reasonable prices. Both these devices run Windows Phone 8 off of 1GHz dual-core processors and provide a fluid UI experience. Nokia’s ClearBlack display technology makes legibility a non-issue in direct sunlight. That coupled with a host of Nokia’s pre-loaded apps, including Nokia Maps and Drive, makes these devices quite a value for money.

High end features, low price tag

The Ultraphone 701HD from Zen Mobiles features a 1.2GHz quad-core processor from MediaTek and runs on Android Jelly Bean v4.2. Its 720p HD display and 8MP camera also makes it an option to seriously consider. All of this is offered at just Rs 12,000, making it a very affordable device.

iPod shuffle

iPod shuffle

Sleek, anodised aluminium. Eight gorgeous colours. Its main body is crafted from a single piece of aluminium, so iPod shuffle feels solid, sleek and durable. And the colour palette makes it the perfect fashion accessory.

Goes anywhere. And with anything.

iPod shuffle isn’t just portable. It’s wearable too. Clip it to your shirt, jacket, workout gear, backpack or purse strap, and it stays put — whether you’re running an errand or running round the track.

Hundreds of songs to go.

Never leave a favourite tune behind. Along with up to 15 hours of battery life,1 iPod shuffle gives you 2GB of storage capacity, enough for hundreds of songs.2 That’s plenty of room for the essential songs of your workout or commute. And for multiple playlists, podcasts and audiobooks too. 

Control your music with just a click.

 The big, clickable control pad on the front of iPod shuffle makes it easy to see and use the music controls. Press the centre button to play and pause. Press the outer buttons to skip forward or back and adjust volume. Click, click, click. It’s music to your fingers.

Play it your way.

Maybe you’re the spontaneous type. Or maybe you prefer a little order. Just flip the shuffle switch to suit your listening style. Flip it to the left, and you’ll hear your music in a refreshingly random way. Flip it to the middle, and your songs play in order. Or flip to the right to turn iPod shuffle off.

GSM Vs CDMA Technology

Depending on the type of mobile phone you possess, your handset can use either the GSM or CDMA Technology. GSM means Global System for Mobile communications while CDMA is Code-Division Multiple Access. The GSM technology is widely used by over 450 million subscribers worldwide. It allows for international roaming and is more advantageous than CDMA because the latter does not work in areas such as France, Germany, a few European locations, and in Asia. The downside of GSM technology, however, is that it hasn’t fully accessed the American region. CDMA technology, on the other hand, also provides for an increased mobile communication security and efficiency.

There are many types of mobile phones available in the market nowadays—each handset can be taken to cater to a specific target market, but you’ll find that people now just purchase the mobile phone that both appeals to their eyes and satisfies their curiosity for techie features. It doesn’t matter if you’re just a simple college student or a top-notch business CEO—you probably own the same kind of mobile phone.

How To Start A Blog


How To Start A Blog
 by Nitish Bhardwaj


Friends and family members often ask me how to start a blog, and I always enjoy explaining the advantages of a blog over a traditional website, but it is a lot information to take in over dinner. I thought I would document the process to make it easier to understand.

 

 

Decide What You Want To Blog About

There are a lot of bloggers on the web already. If you want to attract readers, you are going to need to establish your credibility. Don't just blog about anything. Pick a topic you are are passionate about. Something that you have lots of experience with.
Decide: To Host or Not To Host

When it comes to starting a blog, your biggest decision will be whether you want to host the blog yourself, or use a free blogging service that is hosted for you.

Free Blogging Services

Yes, it's free, but nothing is really free. When you start a blog with a free blogging service, you don't get your own domain. You get something like nithba79.blogspot.com (where there are a million other blogs at blogspot.com) and you don't actually own the blog. If you ever do decide to move to your own domain, you have no way to take your readers with you, because you have no control over the site.

Cheap - Host your own blog using WordPress free Blog software

This is the method I suggest, because it offers much more flexibility and freedom to do what you want. You will have your own domain name, like google.com, facebook.com. You can get this for as little as $30 per year. In my experience, WordPress is excellent free blog software that allows you flexibility and room to grow.

If you want to go the free blogging service route, check out links to free blogging services. If you want to host the blog yourself, read on.

Find a Domain Name

For me this part is fun. You know what your theme is already, so now you have to find a good domain name.

Find a Web Host for Your Blog

By far, the easiest way to get a website is to go with a hosting company that offers "1 click installs", or instant installations for Blogging and Forum software. Blogs and Forums make it possible for someone with no experience to get good content up fast.
