Nelson English Workbook 4

“Cool Tech” is a thrilling journey through the physical side of the virtual world. Marvel at the technology that keeps you connected, from the ships installing lines deep in the ocean, the robots locating wire breaks, the satellites beaming signals across the earth, the teams retrieving and splicing lines together, to the servers directing and feeding internet traffic around the world. Plus, take a look back at the history of the internet, exploring the people and inventions that led to its creation and tour a virtual museum to see how the technology has progressed over the years changing the lives of ordinary people everywhere.
