Summary The Internet is a worldwide collection of computer networks,
accessed through ISPs.
Internet Protocol (IP) controls the structure and addressing of data packets for transport through the Internet cloud.
ISP Network Operations Centers (NOCs) utilize high-end, high-speed devices with redundancy.
Home networks feature multi-function devices which perform switching and routing.
Networks use physical cabling media which must conform to standards in construction and termination.
Cabling best practices are designed to reduce attenuation and crosstalk.
