What is a “gateway” in networking?
a) A device that connects two different networks
b) A type of firewall
c) A tool for encrypting data
d) A device for storing network configurations
Answer:
a) A device that connects two different networks
Explanation:
A gateway is a network device that connects two different networks, such as a local area network (LAN) and a wide area network (WAN), or a private network and the internet. It acts as a point of entry or exit for data moving between these networks.
Gateways translate data between different network protocols, allowing devices on different networks to communicate with each other. For example, a home router often functions as a gateway, connecting a local network to the internet.
Gateways play a vital role in facilitating communication between disparate networks, enabling seamless data transfer and interaction across multiple systems.
