Final answer:
An Internet connection where one computer provides network access to another is known as Internet Connection Sharing (ICS) or a network bridge. The primary computer acts as a router for the others, allowing multiple devices to share a single Internet connection.
Step-by-step explanation:
An Internet connection where one computer connects to the Internet and also provides network access to another computer is known as Internet Connection Sharing (ICS) or a network bridge. This arrangement is commonly used when only one computer has a direct connection to the Internet, often via a distinct hardware interface like a modem or a broadband connection. The primary computer that is connected to the Internet acts as a gateway or router for the other devices, which may connect to it via Ethernet, Wi-Fi, or even a USB connection.
The computer with direct Internet access uses software to handle the routing tasks, essentially sharing its connection with the other devices. This approach can be beneficial in situations where multiple devices need Internet access, but there is only one available external connection point. It is also a cost-effective solution for small networks, eliminating the need for additional hardware like a stand-alone router. However, this configuration may not be as robust or secure as using dedicated networking hardware.
