The Full Form of GIAS is Gateway Internet Access Services.

An Internet gateway is a network “node” that connects two different networks that use different protocols (rules) for communicating. In the most basic terms, an Internet gateway is where data stops on its way to or from other networks. Thanks to gateways, we can communicate and send data back and forth with each other.

Gateways can take several different forms from hardware to software – including routers and computers – and can perform a variety of tasks. These can range from passing traffic to the next ‘hop’ on its path to filtering traffic, proxies, or protocol translations. Because gateways are, by definition, at the edge of a network, they are often combined with firewalls, which keep out unwanted traffic or ‘foreign’ computers from a closed network.

For Internet connections at home, the Internet gateway is usually the Internet Service Provider (ISP), who, in this case, offers access to the entire Internet through its own network. If you have a Wi-Fi connection at home, your Internet gateway is the modem or modem/router combination that your ISP provides so that you connect to the Internet through their network.
