What are wireless routers used for?

Wireless routers are the same as wired routers, but there is one more wireless function, the router can share a multi-computer Internet access, which means that a network of multiple computers share the Internet, and the router dial-up is entered into the router, so the computer connected to the router can go to the Internet without dialing.

A router is shared by one network cable. Only 1 time is counted as surfing the Internet at the same time. Now it's all about switching and routing as one. If you buy a few bites, the main thing is to see how many people share the Internet. Generally, 4 mouths are enough.

With a wireless router, your book can go wireless, and you don't need to plug in the network cable.

To explain the concept of a router, you first need to know what a route is. The so-called "routing" refers to the behavior and action of transmitting data from one place to another, and the router is the machine that performs this behavior and action, its English name is router, which is a network device that connects multiple networks or network segments, and it can "translate" the data information between different networks or network segments, so that they can "read" each other's data, thus forming a larger network.

To put it simply, routers have the following main functions:

First, network interconnection, the router supports various LAN and WAN interfaces, which are mainly used to interconnect LAN and WAN to achieve mutual communication between different networks;

second, data processing, which provides functions including packet filtering, packing**, priority, multiplexing, encryption, compression, and firewall;

Third, network management, routers provide functions including configuration management, performance management, fault tolerance management, and traffic control.

In order to complete the work of "routing", the relevant data of various transmission paths is saved in the router, and the routing table is used for route selection. The route table stores the flag information of the subnet, the number of routers on the network, and the name of the next router. The routing table can be fixed by the system administrator, dynamically modified by the system, automatically adjusted by the router, or controlled by the host.

There are two concepts involved in the name of an address in a router: a static routing table and a dynamic routing table. The fixed routing table set by the system administrator in advance is called the static routing table, which is generally pre-set according to the configuration of the network when the system is installed, and it will not change with the change of the network structure in the future.

A dynamic routing table is a routing table that is automatically adjusted by the router according to the operation of the network system. According to the functions provided by the routing protocol, the router automatically learns and memorizes the network operation conditions, and automatically calculates the best path for data transmission when needed.
