What are the main functions of the router? The basic functions of the router are as follows:

First, network interconnection: routers support various LAN and wide -area network interfaces, mainly used for interconnected LAN and wide -regional networks to realize interoperability of different networks;

Second, data processing: provides functions including group filtration, group forwarding, priority, reuse, encryption, compression and firewalls;

Third, network management: router provides functions including router configuration management, performance management, fault -tolerant management, and traffic control.

No broadband dial. In the past, many of us dialed the Internet through the hub, and it would always be troublesome, but if we connect the cat to the router, we saved the dial. As long as your router keeps open, you can go online immediately. Of course, the computer can also set automatic dial.

*Basic functions are that many people can go online at the same time. The use of broadband to use it is too wasteful to use it alone, so if other people at home or office need to surf the Internet, then we need to buy a router and link the computer or mobile phone to the router to achieve the purpose of surfing the Internet.



You can set up a wireless network. If you want a notebook or mobile phone, you can use WiFi to access the Internet. We need to buy a wireless router. Simply set up some to set up a family wireless network.

You can control it through the settings in the router, such as filtering out some game chat websites or bad spam websites. The office is generally a website that blocks Taobao, Tencent, and other websites.

In the process of forwarding packets, the router has decomposed large data packets into appropriate size data packets in accordance with the predetermined rules in accordance with the predetermined rules.

Multiple protocol routers can connect to network segments that use different communication protocols as platforms that connect to network segments of different communication protocols.

The main task of the router is to guide the communication to the destination network, and then reach the specific node station address. The latter function is completed through the network address. For example, the distribution of the network address part is specified as a group of nodes in the network, subnet and area, and the rest are used to refer to the special station in the subnet. The layered addressing allows routers to information on the network storage address with many festivals.
