Cell phones are one of the truly great technological advances of our times. In just a handful of years they have gone from being massive clunkers that you almost needed to carry in a backpack, to slim line devices that you could almost fit into your wallet.
Cell phones these days do more than just make calls; you can send photos, organize your calendar and to-do lists, surf the internet, play games, listen to music and take photos - in fact everything that you can do on a home PC and more! With so many hi tech varieties on the market, it's easy to get lost in technical jargon. In this article we will take a look at a few of the common terms that you may encounter.
Bluetooth
Bluetooth is a way that phones connect wirelessly to other devices. This is a pretty common feature and is very useful to connect to a wireless headset or car kit, or even another phone to transfer files.
MP3 player
Many phones have built in MP3 players. MP3 is a file format which allows music to be compressed, so you can fit more on your phone. Phones that play MP3s often have a paid download service so you can get more tunes on your phone.
Megapixels
The resolution of a digital camera is measured in megapixels, often abbreviated to mp. 1 mp is equal to 1 million pixels, and 1 pixel is one of the tiny dots that make up a digital image. Be aware that huge megapixel counts are not always a good thing - cramming more resolution into a small camera sensor can decrease picture quality. 3-6mp is probably plenty for typical phone camera use.
GPS
GPS, or Global Positioning System is a method that phones use to identify exactly where the phone is located on the planet. This allows the use of some great mapping software for navigation.
