Answer:
Gateway is used to communicate between different networks. It acts as a bridge or translator between two different networks, allowing them to exchange data and communicate with each other.
Here is a detailed explanation:
What is a Gateway?
A gateway is a networking device that connects two or more networks together and facilitates communication between them. It serves as an entry or exit point for data traffic between different networks, allowing them to exchange information.
Function of a Gateway:
The main function of a gateway is to perform protocol conversion and data translation between different networks. It enables communication between networks that use different protocols, such as TCP/IP, Ethernet, or ATM.
Types of Gateways:
There are different types of gateways, including:
1. Network Gateway: Connects different types of networks, such as LAN (Local Area Network) and WAN (Wide Area Network).
2. Protocol Gateway: Translates data between different protocols, such as converting data from TCP/IP to IPX/SPX.
3. Application Gateway: Enables communication between different applications or services running on different networks.
4. Security Gateway: Provides security features such as firewall and VPN (Virtual Private Network) to protect the network from unauthorized access.
Advantages of using a Gateway:
1. Interoperability: Gateway allows different networks to communicate and exchange data seamlessly.
2. Protocol Conversion: It enables data translation between networks that use different protocols.
3. Security: Gateways can provide security features to protect the network from external threats.
4. Scalability: Gateways can be easily added or upgraded to accommodate the growing needs of the network.
In conclusion, a Gateway is used to communicate between different networks by acting as a bridge and facilitating data exchange between them. It plays a crucial role in enabling interoperability and ensuring smooth communication between networks that use different protocols.

Understanding Network Communication
In the context of networking, various components facilitate communication between different networks. Among the options provided, a gateway is the correct answer.
What is a Gateway?
- A gateway acts as a "gate" between two networks, allowing them to communicate with each other.
- It translates communication protocols, data formats, and other network specifics to ensure seamless interaction.
Functions of a Gateway
- Protocol Translation: Gateways can convert different protocols used by various networks, enabling devices on one network to communicate with those on another.
- Data Handling: They can manage data traffic, directing it to the appropriate destinations and ensuring that packets are correctly routed.
Comparison with Other Options
- ADSL (Asymmetric Digital Subscriber Line): Primarily a technology for transmitting data over telephone lines, it is used for internet access rather than inter-network communication.
- HDSL (High-bit-rate Digital Subscriber Line): Similar to ADSL, HDSL is a type of DSL technology that provides high-speed internet access but does not serve as a communication bridge between different networks.
- Modem: A modem modulates and demodulates signals for data transmission over telephone lines or cable systems but does not facilitate communication between distinct networks.
Conclusion
In summary, a gateway is essential for connecting different networks, enabling interoperability and data exchange, while ADSL, HDSL, and modems serve specific purposes within network infrastructures. Thus, the correct answer is option 'C' – Gateway.
