What's your 100th object?

Rory Cellan-Jones published a nice post this morning on his technology blog about his ideas for the 100th object in our series.

His choice of a simcard is a very clever one because it gets around having to pick any particular model of mobile phone.

Mobile phones and wifi connected technology, such as the iPad, have been popular suggestions so far. However, I like the suggestions that try and dig a little deeper into their circuitry for the thing that lies at the heart of what they deliver.

The simcard is definitely one of those, but my favourite so far is from James Simcock, one of the 主播大秀鈥檚 mobile gurus, who has nominated the IP Packet Switch. It sounds like a con trick from from The Real Hustle but he describes it as 鈥渢he enabling technology behind the internet revolution.鈥

Essentially it鈥檚 the device that lets your pc or smartphone send and receive data over the internet; chopping huge files into tiny little pieces that can be delivered independently and then reassembled.

The router in your home would be an example of a packet switch. And as most of us know from experience of the little green light fizzing out one day: no router, no internet.
