Internet networks are systems that connect computers and devices globally, allowing them to communicate and share information. These networks use various technologies, such as routers, switches, and cables, to transmit data. The most common type of network is the TCP/IP network, which forms the foundation of the Internet. There are different types of internet networks, including local area networks (LANs) and wide area networks (WANs). LANs connect devices within a small area, like a home or office, while WANs cover larger distances, linking multiple LANs. Together, these networks enable seamless communication and access to resources worldwide.
