In the world of computers, networking is the practice of connecting two or more computing devices to share data. Networks are built using a combination of computer hardware and computer software. Some networking explanations in books and tutorials are highly technical and designed for students and professionals, while others are geared more toward home and business computer networking. Here’s a quick, simplified look at the fundamental concepts of networking.

Networks can be categorized in several ways. One method defines a network type based on the geographic area it covers. Networks can also be classified based on topology or the types of protocols they support.
The building blocks of a home computer network include adapters, routers, and/or access points. Wired (and hybrid wired/wireless) networks also include cables of various types. Finally, large-scale business networks in particular often use other sophisticated equipment for specialized communications purposes.
Ethernet is a physical and data link layer technology for local area networks. Homes, schools, and offices around the world all use standard Ethernet cables and adapters to network personal computers.
