Thanks to all people who are doing yeoman service to science & Technology.

Answer 2

Most of them still go by cable although nowadays it's usually fibre-optic cable. Satellites are mostly used as temporary replacement for circuits lost when some trawler drags up a cable where it comes up onto the continental shelf ; it takes a while to find the break and patch it so it's handy to be able to switch circuits to satellites when that happens ( always assuming there isn't enough spare capacity on the other cables running under the atlantic).

Answer 3

Nowadays the answer is satellite. But the first ones actually did have a cable ("the transatlantic cable") buried in a trench that a cable-laying ship dug and then backfilled under the sea bed. That was in the 1850's first for telegraph and then for telephone.

Answer 4

HAHA--actually they did....there is a huge trunk of phone wires that connects NYC with the UK that was laid down in the 30's/40's. The original wire was made out of copper. HOwever, modern phone calls and systems will use satellites to transmit calls around the world. You call, your call is transmitted via fiber optic to a routing station which routes it to the most open next routing station which takes it to a transmitting station...then your call is beamed to the satellite and is beamed down to a receiving station in the UK somewhere and then routed to whereever it is going and vice versa. Once the original call is made, then it makes a link between the two and you talk without lag. The Copper trunk is still there and is still used til today for special calls...ie. the presidents red phone.

As many individuals have been unborn or babies while the final referendum became held re starting to be a member of the EEC, sure, there must be a referendum on Europe. The EEC is huge gravy prepare for mrmbers and particular worldwide places vastly (unjustly subsidised farmers with little duty.

There looks little duty to the real people. you in user-friendly terms ought to check out the 'nutrition mountains'. (specifically French farmers) are being heavily subsidised to over produce that's lunacy. easily, it is larger to subsidise farmers to diversify and bring plant life/dairy/meat that are briefly grant? the government won't organize a referendum in this as they comprehend maximum British people will vote against our persevered club (and paying subsidies to) the EEC. I have not got any prob with paying for and advertising with different EEC states and being on friendly words with them (the place they cope with us truly) nevertheless yet no longer component of the EEC. I bear in mind while i became a infant, all people reported that they had voted against starting to be a member of the EEC yet all of us comprehend the tip result which has been unfavorable to the united kingdom. became the effect rigged? We urgently want yet another risk to have our say in this.
