computer network is a collection of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes



wired network connection is described as a configuration that involves cables which establish a connection to the Internet and other devices on the network. Data is transferred from one device to another or over the Internet using Ethernet cables.A wired network is simply a collection of two or more computers, printers, and other devices linked by Ethernet cables. 


A wireless network allows devices to stay connected to the network but roam untethered to any wires. Access points amplify Wi-Fi signals, so a device can be far from a router but still be connected to the network. When you connect to a Wi-Fi hotspot at a cafe, a hotel, an airport lounge, or another public place, you’re connecting to that business’s wireless network.
