Computer networking is the gateway of an IP address, which is a combination of hardware or software. This is a network of devices that connect to the network. Gateway 2 networks or workstations, between “Link” or “gate”, do the job Gateway has a network of connected devices that comes with a router, a firewall, a server or a device that connects to network traffic and connects to it. Gateway is a cell phone or computer that connects to a network, but it does not have internet access. The gateway connects to the system from the network but this is the Internet that adds extra security to the gateway.
In the Internet connection, all the other signals are entering the gateway and entering the gateway in the security of the security checks inside and outside of the house. For example, when we connect to the Internet, we will be able to access the incoming internet signals gateway and connect to the PC / Laptop or mobile network. If you are browsing on the Internet or browsing to the Internet, then the traffic on your device is generated and you are entering the gateway on the traffic server, where it is available and it is being used by the traffic server.
It is a firewall that makes the gateway hotter and the firewall is the traditional gateway to go from the inside and outbound traffic to the filter and suspends unauthorized sources. Firewall is a gateway that works but the advancement of the workstation is done by the workstation of a single wall (the wall) that has been blocked or blocked by suspected network signals, but it does not allow unauthorized access to the network.
Gateway function: This data establishes packet transmission routes, it can also localize all processed traffic on different odd network interfaces. Can be a subnet gateway or data link. There is also a specific task, which has not yet been widespread. Now talking about voice gateway is required to transmit sound traffic. Voice gateway is used in the phone.
Operation principle:How does this happen? Gateway is devices that can work on all popular operating systems. We will see the data path of the time when users will press the “Send” button First, an explanation is done using machine languages, which requires a computer. Then all the information in the binary code is encoded. It is divided into data packets. Each of them has the information, what is the part of it and where it is needed encryption is done. The route is determined, and the data packet is sent to the recipient. When they come to their destination, the above procedures are in reverse order, except that the decryption is done. That is, this device works as a gateway-router and now we consider what types of gates are present. We define some gateway.
Default Gateway: In the protocol, the so-called address sends all the traffic, for which it is impossible for the route. This property is also called the entrance of the last hope. A special routing table is used to determine where the data is to be sent. If the final goal is not possible, then they are transferred to it. The last hope gateway was found in those networks where the central router was well expressed, in their client segment, and even smaller in size. In the table, it is given by such records: “0.0.0.0 network with mask 0.0.0.0”. Configuring the gateway of this – it is not complicated (usually configured while installing the drivers)
Additional options for using default gateway: In general, what do they represent and play a role in data transmission? Above, only one possibility was underlined, but it is not providing complete information about whether and why the default gateway allows you to facilitate the coordination of the traffic. how? To do this, it sends all the received data to the central router, which can see a more “voluminous” picture, and accordingly – there is a better chance of finding the recipient, besides it also it is necessary to consider that the routing of the workstation Which table is hosted in, Therefore, there are loops in it, there is a local network segment and default gateway. The latter role is to get all the traffic that was not understood by the first two recipients. When more than one device or equipment units are attached to the same router, the default gateway is available only for the addresses addressing the data. When using multiple connections, this form of data exchange loses its value. In this situation, it is not necessary to configure the gateway for default.
