Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The process of communicating using fiber-optics involves the following basic steps:creating the optical signal involving the use of a transmitter usually ...
In many countries, telephone operators are now gradually rolling out what's calledfiber-optic broadband, which promises much faster connections than traditional broadband but still essentially over the ordinary public telephone network: "much faster" means download speeds of at least 40Mbps (megabits p...
A telephone is not just the thing that sits on your table at home. It's a complete system: the handset at your end, the cable that runs into the wall, a whole collection of communication apparatus (coppercables,fiber-optics, microwave towers, andsatellites) that carries telephone signals ac...
To explain it, Lidin surprised the audience by pulling out a lock of his own hair to show how the prizewinners had laid the foundations for the development of nanoscopy, an ultra-powerful microscope that enables scientists to closely look at the inner workings of a cell, revolutionising disea...
(PhysOrg.com) -- A University of Utah study shows that men hit harder when they stand on two legs than when they are on all fours, and when hitting downward rather than upward, giving tall, upright males a fighting advantage.
A new analysis of European archaeological sites containing large numbers of dead mammoths and dwellings built with mammoth bones has led Penn State Professor Emerita Pat Shipman to formulate a new interpretation of how these sites were formed. She sugges

It is important to note that other ecological factors can also influence social organization and mating system. Habitat use may influence distribution (animals aggregating in certain areas of the habitat due to unspecific physical factors like thermal environment, humidity, etc.; like bats in caves)...
As we've already seen, they can shoot by what's called"line of sight", in a straight line—just like a beam of light. In old-fashioned long-distance telephone networks, microwaves were used to carry calls this way between very high communications towers (fiber-optic cableshave largely made...
That network hooks into the public telephone network and the Internet's mail, web, and other servers using a mixture of fiber-optic and wired connections (orange). Another option is to use a plug-in cellphone-type modem that connects your machine directly to the Internet over a cellphone ...
