"What is the internet? It has revolutionised our lives with its technical capabilities, but how did the internet originate and how did it manage to spread across the world and reach more than a billion users? The internet is a global network of computers that works much like the postal system, only at sub-second speeds. Just as the postal service enables people to send one another envelopes containing messages, the internet enables computers to send one another small packets of digital data.
For that to work, they use a common ’language’ called TCP/IP (Transmission Control Protocol/Internet Protocol). If you are on the net, you have an IP address." -

"How do I use hardware to back up my computer? If your hard drive fails, it’s easy to lose precious photos, videos and emails. But there is a way of preventing this from happening to you – by making sure you have backed them up elsewhere. You can back them up to CD or DVD discs, to external hard drives, and even to online services.
There are two main approaches to backing up your computer. The first, and possibly the most common, is to make copies of important files. The second is to back up your whole PC hard drive. This makes it easier to recover from a disaster, but uses more space." -
