Update: PDF is a file format designed to present documents consistently across multiple devices and platforms. It was developed by Adobe and has since become one of the most widely used formats for saving and exchanging documents. A PDF file can store a wide variety of data, including formatted text, vector graphics, and raster images. It also contains page layout information, which defines the location of each item on the page, as well as the size and shape of the pages in the document. This information is all saved in a standard format, so the document looks the same, no matter what device or program is used to open it.

The two major types of dual-SIM phones are active and standby. This latter feature usually requires an additional transceiver for the secondary SIM card, and as such consumes more battery life. The widespread use of the GSM standard has made it easy for most mobile phone users to use their phones overseas thanks to roaming agreements between operators using the same GSM standard. The first GSM network went live in in Finland.
GSM introduced the concept of the SIM card Subscriber Identity Module card - a detachable smart card that lets users swap their phone number and contacts between handset.
The high data speeds are possibly the most prominent feature, and certainly the most hyped. They enable such advanced features as live, streaming video. There are several different 3G technology standards.
The GPU Graphics Processing Unit is a specialized circuit designed to accelerate the image output in a frame buffer intended for output to a display. GPUs are very efficient at manipulating computer graphics and are generally more effective than general-purpose CPUs for algorithms where processing of large blocks of data is done in parallel.
Modern smartphones are equipped with advanced embedded chipsets that can do many different tasks depending on their programming. GPUs are an essential part of those chipsets and as mobile games are pushing the boundaries of their capabilities, the GPU performance is becoming increasingly important. This media may include up to forty seconds of video, audio, one image, or a slideshow of multiple images. Bluetooth is a short-range wireless technology used to create PANs Personal Area Networks among your devices, and with other nearby devices.
Bluetooth allows you to leave your phone in your pocket, while talking on your phone with a Bluetooth headset - with no wires. You can also exchange contact or scheduling information with other Bluetooth-enabled phones nearby, or send such information to a nearby Bluetooth-enabled printer.
Another common use is to give your laptop computer or PDA wireless high-speed Internet access via Bluetooth and your phone. Many newer automobiles also have Bluetooth, which can interface with a phone in a pocket, to allow automatic hands-free phone capability. More innovative uses include playing a game against someone with a similar phone nearby, or using a special Bluetooth pen to send SMS messages by simply writing them on paper.
This is a 2. Wi-Fi - A type of network that makes use of radio channels to connect either to a local area network LAN or a router linked to the Internet. Companies often have a Wi-Fi system installed inside their buildings. Then visitors and workers with laptops can instantly connect to their LAN. There are also publicly available Wi-Fi links to the Internet. These are called Hot-Spots and may be found in airports, train stations and some cafes.
Wi-Fi does include built-in methods of making a network secure, for example turning on WPA Wi-Fi Protected Access or WEP will only allow authorised users to connect but many people do not bother to switch these methods on, with the result that anyone nearby can connect and access their network. Universal Serial Bus USB : A standard port that enables you to connect external devices such as digital cameras, scanners, keyboards, and mice to computers.
The USB standard supports data transfer at three rates: low speed 1. HDMI is a high definition HD interface standard for the transmission of uncompressed digital audio visual data. HDMI can support i, p, i and p with up to eight channels of audio data.
Since HDMI is fully digital and has no image compression the image quality should not suffer form any image degradation.
