II. Translate the technical text.

This system is called packet switching (as opposed to circuit switching). In a packet-switching system, the information being transmitted (be it data or digitized voice) is not sent in real time over a dedicated circuit; rather it is stored in a nearby computer until a sufficiently sized packet is on hand. Then a very smart computer seizes a channel heading in the general direction of the destination, and that packet of data is transmitted at very high speeds. Then the channel is released. So, except for some necessary supervisory information (destination, error checking codes, etc.) the channel is 100 percent efficient.



When the distant station gets that message no more than a few milliseconds later, it responds with the necessary handshaking information - again, by , accumulating a packet of data, seizing a channel, and bursting the information out over that channel. Again,100 percent efficient.
