The editor will share with you what the gateway devices are in the computer. I hope you will have something to gain after reading this article. Let's discuss it together.

Gateway devices are computer systems or devices that provide data conversion services between multiple networks. Gateway devices are: 1, network switch with three-layer switching function; 2, router; 3, firewall; 4, host with routing function turned on by software.

Gateway (Gateway) devices, also known as inter-network connectors and protocol converters, are computer systems or devices that provide data conversion services between multiple networks. It can be said that gateway devices are connectors between different networks, that is, devices that have to be "negotiated" when data is to be transferred from one network to another.

Gateway Typ

Gateways can be divided into different types according to different standards

By connected network:

Local area network / host gateway: local area network / host gateway mainly provides connection services between mainframe computer systems and personal computers

Lan / LAN Gateway: this type of gateway is very similar to LAN / host gateway, except that this gateway is mainly used to connect multiple Lans using different communication protocols or data transmission formats. At present, most gateways belong to this kind of gateways.

Internet / LAN gateway: this gateway is mainly used for access and connection control between LAN and Internet.

By product function:

Data gateways: data gateways usually provide data conversion functions between multiple networks that use different protocols and data formats.

Application gateway: the application gateway is a special system for data translation in an environment where different data formats are used.

Security gateway: a security gateway is a general term for all kinds of hardware or software that provide system (or network) security. It is an organic combination of various technologies, ranging from low-level protocol packets to high-level specific applications.

The following devices can be used as gateways:

1. A network switch with layer 3 switching function.

2. Router.

3. Firewall.

4. the host that turns on the routing function through the software.

Generally speaking, as long as the network device or host device with routing function can be used as a gateway.
