For my home user, please briefly summarize the difference between a router and a switch

At the same time, of course, you can use a router to surf the Internet.

SwitchYou can understand that the computers connected to the switch form a local area network, so that these computers can exchange information with each other, it is like building a closed village.

The router not only includes the switch function, but also provides a path for people in the village to exchange information with people outside, which is the WAN port of the router.

Router Switches do not have routing functions, so group LAN is more suitable

The routers and switches here are actually the distribution of signals. It doesn't matter which one you choose. The key thing you want to achieve is that there are only two people online.

Then just use a cat. 2 RJ-45 wires.

Connect one computer to another, so that one computer can go on and off the Internet. The other computer can access the Internet through this extranet computer. This is where two computers are required to set up the same network segment.

Hardware requirements: 2 network cards on the external network. Another 1 network card.

For example, the machine settings of the external network:

ip address：

subnetmask：

gateway：

Another: ip address:

subnetmask：

gateway：

Tengda's, TP-Link broadband routing, more than 100 yuan, is suitable for you.

Before the switch, it was mainly the hub, and the hub was equivalent to an urban traffic road, and the road was there, but no one cared how to go, so there was a possibility of conflict.

The switch is equivalent to having a traffic light, and the traffic police, you can drive according to the traffic light or traffic police command.

The router is equivalent to intelligent traffic with navigation, if you want to go from A to B, there may be multiple roads, first of all, the optimal route will be planned, and when some routes can not be driven, it will be automatically recorded, and this road will no longer be selected.

This is not necessarily, some operators provide network cables that can support multiple computers, connect a switch, and directly connect all the computers. This is rare.

Generally on a computer. In this case, you can use one router, and all other computers can access the Internet through this router. If the router does not have enough ports, you can connect the computer to the router through a switch group as a local area network.

You can also use a computer as a server, and other computers will form a local area network with this computer, and other computers will access the Internet through the server. The disadvantage of this method is that if the server is shut down, other computers will not be able to access the Internet.

Well, all of the above is professional

But I believe that if LZ could understand it, I wouldn't have asked so I guess LZ just wanted to split the network, and saw that there were two kinds of routers and switches on the market.

I don't know which one to use

If that's the case.

Just a few of the differences that will be most useful to you:

We need to have an account online, right?

For example, we are now going to divide a network cable between four people.

So if you use a router, then as long as you give the router a network account, these four people can access the Internet.

If we use a switch, we need these four people to have four accounts to access the Internet, and the function of the switch is simply to divide a network cable into many roots

Although there is a switch with a router connection.

But there are already some issues with network deployment scenarios

It is generally used for home use or dormitory.

If each of you has an account to access the Internet.

Just take a switch.

If you only have one account to surf the Internet.

Just plug in a router

That's it

You don't have to think about what to do, you have to worry about it

The router can assign an IP address to each computer, the switch does not have this function, the router has the function of connecting to the Internet, and the switch does not have this function, mainly these two.

The problem of Internet access in the dormitory depends on the method of access.

1. If it is a web login, it may be more troublesome and may not be easy to implement;

2. If the computer is connected, it can be used, there is no login interface, and there is no need to set the IP, you can directly use the switch (the security is relatively poor, and the other dormitories form a local area network), you can also use the router (the security is slightly better, the network segment is different from other dormitories, the dormitory is a local area network, and the dormitory is equivalent to the external network);

3. If the computer uses PPPOE virtual dial-up or fixed IP, then use a router, set the router according to the original Internet parameters of the computer, and then connect the switch if the four ports are not enough.

Knowledge is limited, and that's all I know.

The function of the router contains the switch is more advanced than the switch, and the LAN can be connected with the switch, and a router must be connected to the LAN to make the LAN go to the Internet, so that these machines can access the Internet.

Layer 2 switches cannot dial up and cannot make LAN and Internet connections unaddressable.

Layer 3 switching functions the same as routers.

I'm using the upstairs copy, in addition.

Hubs – Layer 1 devices where all hosts broadcast in the same collision domain can only provide a 10m band.

You're right.

Popular: The router also comes with a switch, and the router function is much stronger than the switch;

Router = Broadband Dial-up + Internet Sharing + Switch.

This popular can't be more popular, it's clear at a glance.

If you don't have money, you buy switches, and if you have money, you sell routers. It's like having no money to buy a copycat domestic machine, but having money to buy an iPhone4.
