What is the server and what is the route

The difference between a server and a router is that a router has a simple structure and looks like a small box. It is mainly used for sharing network broadband. It allows multiple computers to use a single account and access the network at the same time, which can reduce network costs.

A server is the equivalent of a computer host. In addition, it is configured more restrictively than a normal host, as it is used to transmit network data, most commonly, running on a server. They are usually equipped with G-level firewalls and no less than 100m of telecommunications dedicated broadband (Netcom).

There is an essential difference between the two. One is used for data storage and operation, and the other is used for transferring data. A distinction should be made when understanding.

The composition of the router is very simple, the appearance is like a small box, mainly used to share the network broadband, can allow multiple computers to use an account at the same time, and access the network at the same time, which can save the Internet fee The server is equivalent to or serving a computer host, not only that, his configuration is more stringent than that of ordinary hosts, because he is used to carry network data, and the common ** is running on the server, It is generally equipped with a G-level firewall and no less than 100M telecommunications (Netcom) private broadband, which is essentially different, one is used for data storage and computing, and the other is used for transmitting data, which should be distinguished when understanding.

It's hard to put it into words,,, the two are not a level of things,,, the server has a super wide range of uses, it is simply inseparable from our lives,,Mobile phone Internet view**,,It's all the credit of the server,,The so-called service,,You can imagine what we use,See the server,,, router is relatively simple,,Jingbend,That is, the route,,Bright book boring,,To show you the way to **,,, personal opinion is for reference only。

A server is something that is specifically designed to store some network data, including a variety of other data. The router is actually the interface of a network, and after passing the router, the network is connected to more places.

In other words, a server is like a high-configuration computer, and a router is like an optical modem that provides you with Internet access at home, which is understandable.

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, routers support a variety of LAN and WAN interfaces, mainly used to interconnect LAN and WAN, to achieve different networks to communicate with each other;

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 stored in the router routing table (routing

table) for routing. 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 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. The router is based on a routing protocol (routing

protocol) to automatically learn and memorize network conditions, and automatically calculate the best path for data transmission when needed.

Virtual server features in the router:

In layman's terms, you can map the port of any IP in the private address to the port in the public IP, which is the port mapping function.

Through the router's virtual server function, port 80 is mapped to port 80, so that all Internet users can access the ** on your LAN through access.
