Cloud computing

Traditionally, once you've spent a small fortune on a new computer, you'll then expect to fork out for a raft of software to make sure it can perform the tasks you want it to. The concept of cloud computing – something web companies such as Google are pushing – could change all that. We're all familiar with networks that offer you storage space in a separate location that's shared by a number of users, such as online storage services and many office networks. But cloud computing lets you access and operate web-based software from any machine, as well as your contact information and personal data.
If you've used Google Docs then you've already enjoyed the benefits of cloud computing. Google Docs lets you perform tasks similar to those in programs such as Word or Excel, but without you having to download anything to your PC.

What is a 'cloud'?

The term cloud computing (not to be confused with Wi-Fi provider The Cloud, describes a network, in most cases the internet, that can be publicly accessed. All an individual using the network needs to do is get connected and choose the service they wish to use. Once they've done that, they're ready to go and can operate the services via a web browser. You don't even need to have a laptop or a PC to connect to the cloud – a web-enabled mobile phone will do. Everything required to perform the tasks that the cloud network offers is hosted centrally. The individual computers connected to the cloud make requests and the system automatically designates the necessary resources to accomplish the task. The allocation and use of the resources can also be monitored. The concept of cloud computing isn't new. Many services have for a long time offered all the tools necessary to get certain things done online – look at web-based email applications such as Hotmail, for example. However, cloud networks can offer far more than just email.
