What is Internet Connection Sharing (ICS)?
Internet Connection Sharing (ICS) is a feature that allows multiple devices to share a single internet connection, typically from a laptop to a desktop or other devices. This is particularly useful in scenarios where a desktop computer does not have its own dedicated internet access or when a wireless router is not available. By utilizing the laptop’s internet connection, users can connect their desktops through various methods, including Ethernet cables or Wi-Fi.
ICS works by designating one device (the laptop) as the “host” that receives the internet from a modem or router. The host shares this connection with other connected devices, acting as a bridge. This allows users to enjoy online activities on their desktop without needing separate internet installation or equipment.
