In this vedio content the following content has been explained 

Gateway
1. A gateway is a hardware device that acts as a "gate" between two networks. It may be a router, firewall, server, or another device that enables traffic to flow in and out of the network.

2. Networks have a boundary that limits communication to devices that are directly connected to it. Due to this, if a network wants to communicate with devices, nodes or networks outside of that boundary, they require the functionality of a gateway. When one network wants to communicate with another, the data packet is passed to the gateway and then routed to the destination through the most efficient path. 

 3. A gateway will also store information about the host network’s internal paths and the paths of any additional networks that are encountered.

4. Gateways are basically protocol converters, converts information, data or other communications from one protocol or format to another. An Internet gateway can transfer communications between an enterprise network and the Internet.

5. Gateways can be used for both WAN and LAN interconnects.

6. Gateway operating on any layer of the 7 layer of  open systems interconnection (OSI) model.

Type of Gateways
There are two different types of gateways in computer network which are divided on the basis of direction of data flow  are
1. Unidirectional Gateways.
2. Bidirectional Gateways.

1. Unidirectional Gateways:-These gateways allow to broadcast the data only single direction. All changes are made in the source terminal, and they are replicated to destination node or application. But, they do not permit any change in the destination node are not replicated in the source node. These types of gateway work as archiving tools.

2. Bidirectional Gateways:- Bidirectional gateways are capable to flow the data in both directions. In these gateways, all changes are made to the source node are replicated in the destination and vice-versa. These types of tools are capable to perform all tasks as synchronization tools.

Advantage of Gateway
1. Gateway Used to expand the network.

2. Gateway is a server so it provides some security.

3. Gateways are connected two different types of networks.

4. Protocol conversion is done.

5. Effectively handles the traffic problems.

6. Establishes connections between internal network and external network.

Disadvantage of Gateways
1. Not an intelligent device. 

2. So noise prevention is not done.

3. Never filter out the data.

4. Some what costly.

5. Protocol conversion is done so transmission rate is slower.

6. Some what hard to handle.
