A2DP Bluetooth (Advanced Audio Distribution Profile)

Now a days, you must have read that smartphones are coming with A2DP Bluetooth so here I tried to give idea what Is A2DP Bluetooth, Hope you like. Bluetooth has more than 36 profiles one of which is A2DP. Others are like HFP (Hands-free calling through the stereo) , AVRCP (Control over music playback directly from the stereo)  OPP (Uploading of contact info to the stereo) and many more. To read more about Bluetooth profiles on Wikipedia : http://en.wikipedia.org/wiki/Bluetooth_profile )

This profile defines how high quality audio (stereo or mono) can be streamed from one device to another over a Bluetooth connection.  For example, music streamed from a mobile phone to a wireless headset. Now a days, consumer demand for wireless everything has meant high quality wireless audio has to be provided, and because you can’t change the reliable, low quality handset profile in Bluetooth, the A2DP profile has been created to compliment it by providing the bandwidth to send high quality audio. All other Bluetooth communication happens through the much wider data layer. A2DP sets aside a section of the data layer and sends high quality audio through it.

Many Bluetooth 1.1 and 1.2 mobile phones and portable media players do not natively support A2DP, while some newer Bluetooth 2.0 headphones do support it. Bluetooth headphones, especially the more advanced models, often come with a microphone and support for the Headset (HSP), Hands-Free (HFP) and Audio/Video Remote Control (AVRCP) profiles. 

Essentially, A2DP creates a "Source/Sink" relationship between your phone and your stereo, in which your phone, the source, sends signal to your stereo, the sink. A2DP is also used in products such as wireless headphones and wireless speaker systems.

Google Nexus 5 with Android 4.4 KitKat

Yesterday 1^st nov. on the time of Halloween as well as Diwali Google took the curtains off the nexus 5 smartphone developed with partnership of LG with a totally new android version of operating system android 4.4 KitKat. Google said that this smartphone is open for international market in play store and it’ll be available in india soon. It is surprising that nexus 5 is not more costly as it’s previous version though it has many good features than previous versions.

The Nexus 5 has 4.95-inch full-HD IPS display and is powered by a 2.26GHz quad-core Qualcomm Snapdragon 800 processor alongside 2GB of RAM.  It has good and high resolution camera then privies version it is as follows: 8.0-megapixel rear camera with optical image stabilization and a 1.3-megapixel front camera. Two different mode storages wise are 16GB (Rs. 28,999 /  $ 349) and 32GB (Rs. 32,999 / $ 399)  with Black and White colours each

According to the news Google and LG both companies are happy to partnership again to develop a fastest nexus phone ever made. One of the big features in KitKat, HDR+. It's a pretty standard HDR feature — silently using a burst mode to take a bunch of photos and composite them together

Overall, the Nexus 5 looks like a wildly capable Android phone. It's fast and big with a beautiful screen and all the accoutrements you'd expect on a flagship phone.

SSD Vs. HDD

Today, in this fast world people cannot afford compromise with speed. Now a days there are two technologies in the market conventional HDD (hard drive) and SSD (solid state drive) for storage of data. User has to evaluate his requirements as well as Budget (of course!!) before selecting a storage device. This leads to question how? And which is best in different scenarios?

Introduction to HDD and SSD: Conventional HDD drives contain multiple disks called platters, which are covered in a magnetic coating and then rotated at high speed. Drive heads then move across the platters, changing the magnetisation of the material beneath to record data, for reading stored data in it does the same job. It stores data though power is off in technical term it is non-volatile memory. Here rotation is required in order to read or write data, takes considerable time as well as power which has major impact on performance of pc. And of course power consumption is one of major factor affecting device running on battery like laptop, tablet.

An SSD performs the same function (saving your data while the system is off, booting your system, etc.) as an HDD, but instead of platters, the data is stored on interconnected flash memory chips. This eliminates the problems of platters, moving heads and problems caused by generation of electromagnetic field due to rotation of head. The flash memory chips can either be permanently installed on the system's motherboard (like on some small laptops and netbooks). This technology is essentially being used in mp3 player, memory cards, cameras and in many more devices.

SSD drive can give excellent performance at the cost of price in other words if you want high performance that you need to pay more. Conventional HDD works like fan, which takes time to reach to the full speed after turning it on while in SSD there is no problem of speed it gives maximum rate of data transfer at any time i.e. it is ready anytime. SSD is also more reliable than conventional HDD. It is advisable for users to use SSD who can’t afford the compromise in speed.

Recently Samsung unveiled the first 3D  NAND memory.
