Since a computer network is a very complex system, a structured design approach is often adopted in order to simplify its design.

Computer network architecture refers to the logical structure and function distribution of the entire network system. A computer network system is a very complex system. The structural design approach of breaking down a complex system into several easy-to-handle systems and then dividing and conquering them is the most common method used in engineering design.

Layering is one of the best ways to decompose a system.

The benefit of hierarchies is that each layer implements a relatively independent function. The hierarchical structure also has one thing to do with communication, understanding and standardization. The hierarchy of computer networks is generally represented by a vertical hierarchical model.

This seems to be gray and simple, it is the conventional home network department, the home Internet will have a junction box indoors, home decoration needs to be offline from the junction box to each room that can use the network network cable (whether you use it or not, wiring is a must), class A twisted pair, cat and wireless router depending on the home improvement reservation situation, standard connection: the outer line into the box is replaced with a multi-** junction box, then the cat and the router can be put into the junction box at the same time, the outer line and the cat connection; The cat is connected with the router, and then the route is connected with the network cable of each house, so that no matter which house the notebook can enter the Internet through wired or wireless connection, the mobile phone enters the Internet through wireless, and the gateway is:, IP allocation:

As long as you find two of your favorites in the middle, you can allocate two notebooks respectively, note that the IP cannot be repeated and in addition to the gateway, such as: one is used, the other one is available, not the same 6 or the same 8, subnet mask:, so that the entire home network is successfully configured and can be used.

I found two pictures on the Internet, you see:

No one answered that I'll join in the fun, the separator picks up the cat, the cat connects to the WAN port of the router, since it's a wireless router, then let other devices access the Internet wirelessly, configure it, connect a computer to the LAN port of the router with a twisted pair, open the router, generally enter the router management page in the browser, and the next....No, the network segment, subnet mask, and IP are assigned to these devices from one to another....

1.Signal splitter - modem - wireless router - desktop, laptop, mobile phone in parallel. (Desktop wired, laptop phone wireless).

2.The outer port of the wireless router dynamically obtains the IP address, and the inner port is used as the gateway, which is given to the desktop, and then to the notebook and mobile phone. It's a mask.

3.First, set the external port of the router to PPPoE dial-up Internet access, and set the account password given by the operator. The inner port is set to the address range.

4.It can be obtained automatically, or it can be set manually, if it is set manually, it can be set by pressing the plan in step 2 of the button.
