Final answer:
Ethernet, a key technology in wired LANs, includes components such as Ethernet Cable, Switch, Router, and NIC. The Internet and the World Wide Web, now essential parts of global communication and economy, evolved from early network concepts and systems like SABRE and proposals by visionaries like JCR Licklider.
Step-by-step explanation:
The Ethernet is a foundational technology for wired local area networks (LANs) and first emerged from the research in network communication done in the 1960s and 1970s. Ethernet became the most common local area network standard and involves several components to function properly. These include an Ethernet Cable, a device called a Switch to manage data traffic, a Router to direct data to the appropriate networks, and a Network Interface Card (NIC), which allows a computer to connect to the network.
Through the evolution of networking, influential systems such as the semi-automatic business research environment (SABRE) and concepts like the 'Intergalactic Computer Network' proposed by JCR Licklider paved the way for what would become the interconnected network landscape we know today, including the Internet and the World Wide Web.
