Study about Gateway Network Device

1. Gateway
- A network node that connects two networks using different
protocols together.
- It also acts a bridge between two networks. It may be router,
firewall, server, or other devices that enables traffic to flow in
and out of the network.

3. Brief history
- Early gateways were used in Arpanet (precursor to the internet).
- Evolve from basic routers to intelligent security-enhanced
devices.
- Modern Gateways integrate AI, encryption, and cloud-based
services.
- Essential in IoT cloud computing, and enterprise networks today.

4. Key Features:
- Can be hardware-based (routers, firewalls) or software-based.
- Supports multiple communication protocols.
- Provides traffic control and routing capabilities.
- Enhances network security and performances.

5. Functions of Gateway
- Connects different networks and enable data transfer.
- Performs protocol conversion for seamless communication.
- Enhances security by filtering and monitoring traffic.
- Acts as a firewall, preventing unauthorized access.
