Technology
Normal telephone numbers (following the E.164 standard) may be of any length, and so when dialed from landline telephones, the network must apply heuristics to determine when dialing is complete — in the US, for example, dialed numbers are generally seven or ten digits long, sometimes requiring "1" to be prefixed (the trunk digit). On mobile phones, numbers are terminated with the "Send" or "Call" key and sent all at once over the network, so the network knows the end of the dialed number, and thus one can use short numbers without clashing with longer numbers.
For instance, on a land-line phone, one could not use the short code 12345, since then one could not dial the phone number 1-234-555-4626 (or any other number that shared the prefix 12345), but on a mobile phone there is no such ambiguity.

Famous quotes containing the word technology:
“Radio put technology into storytelling and made it sick. TV killed it. Then you were locked into somebody else’s sighting of that story. You no longer had the benefit of making that picture for yourself, using your imagination. Storytelling brings back that humanness that we have lost with TV. You talk to children and they don’t hear you. They are television addicts. Mamas bring them home from the hospital and drag them up in front of the set and the great stare-out begins.”
—Jackie Torrence (b. 1944)
“Technology is not an image of the world but a way of operating on reality. The nihilism of technology lies not only in the fact that it is the most perfect expression of the will to power ... but also in the fact that it lacks meaning.”
—Octavio Paz (b. 1914)
“Our technology forces us to live mythically, but we continue to think fragmentarily, and on single, separate planes.”
—Marshall McLuhan (1911–1980)
