The world of the mobile phone is a confusing one these days, particularly for those wondering how to start a cell phone business. Few things are perhaps as confusing as GSM frequencies and GSM phones that seem to work in some parts of the world but not in others.
Multiple band cell phones and GSM frequencies can be especially confusing for anyone wondering how to start a cell phone business.
So what is the background behind the GSM network?
The GSM network was first suggested by a group of European technicians and policy makers in 1982 and it didn’t take long for consumers and phone makers to adopt the new network after it first emerged in 1991. It wasn’t long before there was growing GSM coverage in an increasing number of countries.
The GSM world grew quickly. There were more than one million subscribers spread over 70 carriers in 30 countries by the end of 1993.
Not only did the new GSM mobile network send and receive all of its information digitally, making it the first 2G mobile phone to be developed it also gave users a great deal of freedom on what they did with it. For the first time they were able to send short written messages to each other for a fraction of the price of a phone call, they could change their carrier and/or go to a different country without getting a new phone.

Quad core computer contains four processors and can be considered a part of multi core processors family. There is hardly any doubt that the performance of quad core computer is much faster than that of dual core computers. However, the performance of quad core computer depends upon the type of programs that run and the algorithms used in those programs.
There is a popular misconception that the quad core computer runs four times faster than the single processor computers. It does work, but for programs that are designed to perform on quad core computer. The codes written in those programs allow the processor to accomplish four different tasks simultaneously. Games such as Gears of War or Crysis which require multiple tasks like audio, physics benefit or AI to run simultaneously can be played through the multi-threading processors of quad core computer.
Performance wise quad core computers are faster in multitasking and parallel programming. For instance, multiple virtual machines can be run with four processors. Hardware virtualization, high-end video game playing provision, video and photo editing, audio transcoding, data folding, 3D rendering, voice recognition facility, the options are so many to choose from in quad core computers. You can run virtual studio on XP, work on Photoshop projects on core OSX install or do any other programs in lunux distro. You can also run XP virtual machine on top of XP. You will be able to run the maximum amount of virtual machines that ESX 3 is capable of running. However the number of Virtual machines you run depends on the memory space of your quad core computer.
