The difference between a router and a cat, elaborate in detail?

The cat is the modem, the modem, is the device that switches the analog signal and the digital signal, to put it bluntly, the first line and the network cable use different types of signals, the role of the cat is to convert the signal back and forth, one end of the first line and the other end of the network cable. A router is a device that simply reconnects digital signals to shunt and strengthen, and all ports are connected to network cables. Of course, there are also two-in-one devices, that is, devices with both routing and cat functions, but in terms of function, the two are fundamentally different.

As for the difference between analog signals and digital signals, to put it simply, analog signals are continuous, like wavy lines you draw on paper, and digital signals are segmented.

The two are different things. Cat meow modem. The computer dials up the Internet through it.

It's like your phone. Without him, he wouldn't have access to the internet. The role of the router is to play a role in the distribution of several computers on a network cable.

One wire is only connected to one cat. On one computer, add a router to enable multiple computers to access the Internet at the same time.

Wired and wireless depending on your needs. You don't have a wireless device. Then it's useless to buy a wireless one, isn't it?

But it is recommended that you bring a wireless one. This will be useful in the future, right? It is also recommended that you cat and wireless router together all-in-one machine.

That's one less device. Save electricity.

The router is wireless and capable of automatic dialing. Cat is a connectivity feature, if you need wireless wifi Internet access, both are indispensable, or you can buy a wireless cat. Hope, thank you.

The cat is converted into binary**, and the router is converted into binary**.

The cat is used to decode the router is used to separate multiple signals.

Figuratively speaking, a cat is a man's wife, and the router is a public lover.

1.Router.

2.The scientific name of the cat is the adjustment demodulator.

The router is for unlimited devices to access the Internet.

To put it simply, Liang or cat is resistant to the core is on the Internet network, and the router can only be on the LAN Chang slag digging (that is, the kind that connects multiple computers to the Internet at the same time).

From the looks of it:

The cat has at least two ports: one is connected to the ** line, and the other is connected to the RJ-45 port (network cable);

The router generally has one port: RJ-45, one is a WAN port, and four LAN ports;

Functionally distinguished:

The cat is a modem, in fact, it is also a kind of computer hardware device, and its main role is to convert various signals when the computer is on the Internet.

The router can be seen as a device that sends the broadband network signal connected to the home to the nearby wireless network equipment through the antenna.

The differences between a router and a cat are as follows:

First, the principle is different. The modem is a kind of modem, which converts the signal of etheric light into a device that converts the signal into an Internet signal, and the computer can only dial up the Internet through the modem. A wireless router is a device that can be distributed to several computers with a network cable and has a wireless transmission function.

Second, the ports are different. Like routers, optical modems also have standard network cable interfaces for connecting routers or computers and other Internet equipment, but optical modems have a special interface for optical signal input, which routers do not have;

Third, the connection is different. One end of the optical modem is connected to the ** cable and the computer or wireless router. The wireless router is connected to the optical modem at one end, and the computer can be connected to the computer through wireless wifi or network cable at the other end.

Fourth, the settings are different. The modem basically does not need to be set up. Wireless routers require a login to set up, which is a bit complicated.
