Back in October, Steave jobs Apple CEO announced that company planned to release an Official software development kit called (SDK) in February which allow third parties software developer to create tools or application that would run successfully on apple iPhones.

Now it is end of February and no SDK is release for third party developers. Anticipation is building to see what Apple is thinking for third party iPhone and iPode software development. We have to wait little longer as SDK release might be delayed into March. The unofficial Apple weblog predicted that initial Apple SDK kit would alpha or beta release, where as full version might be release in the coming year.

Whether Apple going to announce SDK in February or March, main concern is how the company plans to threat third party Apple iPhone application developers. When Jobs announced the release of SDK, he predicted four months of gap between the planned and release of SDK is necessary. They explain “we’re trying to do two diametrically opposed things at once–provide an advanced and open platform to developers while at the same time protect iPhone users from viruses, malware, privacy attacks, etc”

I think we will find some new information regarding to Apple iPhone SDK release within short period of time. Just keep you eye on latest news of apple announcement.

Blue tooth technology become very popular in 21st century, people are getting more and more connected with Bluetooth technology. It is one of the best technology in wireless communication. When it comes in basic learning or understanding, Bluetooth can get quite complicated. I tried to mention key learning points of Bluetooth technology to understand basic functionality and operation of Bluetooth technology.

1) Bluetooth is low overhead, energy efficient communication protocol which is ideal for inter device communication like cell phone, radio or other devices.
2) Bluetooth can operate without providing line of sight.
3) Bluetooth can be operated in more than 100 meter of range. it is mainly depends on implementation.
4) The data channel will change frequency, or hops, 1,600 times in a second, between the 79 allocated channels in the ISM band.
5) Data transmission can be operated at around 2.4 GHz frequency range.

More information will be posted here periodically

Blue tooth technology is being used in various devices like Bluetooth headsets, adapter, and headphones. You can also find Blue tooth keyboard, mouse, and many devises which can be operated by Blue tooth technology. Here is some basic understanding of Bluetooth technology.

Bluetooth technology was developed to allow medium or low bandwidth of wireless connection. Bluetooth version 1.1 having main characteristics are low power consumption and short range wireless networking technology that uses radio waves signal to send data from one medium to another at the rates up to 720 kilobits per second. This Bluetooth specification is best suitable for various classes of devices like radio, cell phones, data card etc which allow transmission in the range of 100 meters. Main advantage of Bluetooth technology is, it is not limited to line of sight transmission since it uses directional waves which are capable of transmitting through obstacles.

Bluetooth is a standard for communication of wireless industries that means it enables the communication of other devices as well. Bluetooth technology used for communication between cell phones, computers, digital cameras, and various electronics devices. The specification of Bluetooth defines a radio system and a “stack” of protocol layers. The highest protocol layer is the application layer, while the lowest layer is the radio. Bluetooth technologies have revolutionized personal connectivity and communication market by providing freedom from inconvenient fixed base lines.

Bluetooth devise is a very small in size, as a result it can be built into one or two very small size of microchip which can be integrate in to electronics devices where wireless operations would be operated. Blue tooth also boasts for power optimization, as it functions at radio frequency which is power friendly and the software is also configurable, which limit the power consumption of the device.

I already discuss basic and essential point to be kept in mind while searching for cheap and reliable web hosting company. Here I will discuss another essential thing which helps you to know about web hosting company.

One more good way to test web hosting services is to observe growth of the web hosting company, look at how profitable they are. Generally chip web hosting services should avoid as they provide bunch of free services and charge so little, as a result they can not possibly make a profit. Due to less profit they are not providing quality services, in that case “you will get what you pay for”. If your web host is a public Ltd company than check weather they are running a profit or not. If it’s running a profit than you are in good hand and you will get good services as well, but if it’s not running profit than you should switch web hosts. If your web hosting service provider is a private company, it will be difficult to figure out if they are running profit or not. In that case you should look around services offered by the hosting company and observe if they offered at exceptionally low prices. If they providing all services at such a low amount of money how they can possibly make money or profit? Here you will get what you pay for and if your web hosting company is too cheap than you must change it to reliable hosting provider, otherwise you might be in trouble.

There are many circumstances affect on quality of web hosting company and services. We will discuss more in the next post. Please give your feedback or suggestion here info(at)eltalearning.com
