    ARPANET was created using a packet switching scheme and the system consisted of a number of individual computers connected by private lines. Packet switching is still the dominant basis of today's data communications, unlike older methods of circuit switching. Previously, circuits were reserved for the duration of only one communicating session; therefore meaning it was only possible to communicate between two parties that were interconnected. However, with packet switching, a data system is able to communicate with numerous machines through the same link, as data is collected into datagrams and transmitted as 'packets' whenever network links are free.

Alternatively, we can have our own RFID tags that have personal settings in them, such as your clothing sizes and preferred colours or materials, so when you are out shopping along the clothes rails, the items which match your preferences will be drawn out, for example, by a small flashing LED light.

    Over distances of about 25 miles microwave repeaters are installed to repeater and boost the signal. A geostationary communication satellite essentially acts as a repeater. The diagram below shows how this works in order to be able to transmit signals around the world. Satellites in the sky are roughly 23300 miles from Earth; therefore the signals have to travel roughly 46600 miles from the sending satellite to the receiving one. These signals are sent via electromagnetic beams that travel at 186,000 miles per second which causes a latency of just 240 milliseconds.
