Way back most families had only one team, and raised no other high-tech devices. Access to the World Wide Web is based on dial-up modems that connect directly with a serial cable in the home team. No LAN is required. The advancement of modern technology and acceptance of high-speed connectivity to broadband in homes, requires that the equipment should be networked to facilitate online access and communicate and share information among themselves. What I mean appliances are computers, game consoles, printers, wired or wireless, and storage devices such as NAS. All devices must communicate with each other via a local network, but also need access to high speed Internet. To do this you must configure a home network. With a home-based network that build technically a local network, which can be wired or wireless communication between networked devices at home, and also share the same Internet connection. The network device control at home is the router. It is usually a device that allows you to configure a cable or a wireless network. You can use the Ethernet cable if you make a wired or Wi-Fi for wireless communications. The router shares the Internet connection with your devices. Once you have your network up, you have unlimited opportunities to correct what needs to its network. Things like laptops, desktop computers, game consoles, servers, print servers, etc. After all devices connect to the router, you can share and distribute their files via the LAN parties did in game consoles , video games, and share photos from your computer.
