What is the difference between a router and a routing modem?

The router, which comes with its own network management and supports a variety of protocols, for example, if you fill in the dialing password and other information, he can automatically dial the number, if it is 4 ports.

It means that you can drive 4 computers to surf the Internet at the same time, of course, if this line has a fixed IP is more convenient

Switches, generally used in the computer room, a cabinet to put a number of computers, each computer has a fixed IP, the switch does not have a routing function!

There must be a cat before there is no computer to access the Internet, and the route is not necessary, it can just allow multiple computers to access the Internet, and so on. Separator Lu You does not have a host, just need to set it up when you just press the route, OK,Then the route to see how many ports there are,No port can press a computer,A cost-effective 8-port is more than 200,Q:382961573

I think you'd better use the switch. Words in your dormitory. It should be the line pulled by the school to access the Internet.

Don't dial or anything. The router you bought also has the function of multiple dial-ups. That is, if you are at home, enter the password of the broadband account.

You can go directly to the Internet. If you use it, you don't use the router as a switch.

The routing modem has ** interface directly through ** on ADSL, and cannot be connected to LAN broadband. And a simple router can be suitable for any hospitality, but if you want to connect ADSL, your simple router needs to be connected to an ADSL cat, because a simple router does not have a ** interface.

The routing modem is a cat with a router, which is suitable for ADSL Internet users.

A simple router is suitable for all kinds of users.

The routing cat is a cat with the road tour function.

The road rover should also be used with the cat.

The cat with the route saves you the trouble of dialing.

Of course there is a difference. One is a cat and the other is not a cat.

To put it simply, the cat is on the Internet network, and the router can only go to the LAN (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:

1. The appearance is different.

The shape of the cat and the router is different, the optical fiber is connected to the cat first, and when the router is connected, the computer can only access the Internet through the cat.

2. The interface is different.

The interface of the cat has PON interface for connecting optical fiber lines, tel interface for connecting fixed **, LAN interface for connecting computers or routers, and IPTV interface for connecting network TV. Routers usually have several interfaces, the blue interface is the home network cable, and the other few yellow ports can be connected to several computers at the same time.

3. The number of layers of the OSI model is different.

The OSL model has seven layers, and the cat only converts analog signals to digital signals, and does not involve finding paths, so the first layer is the physical layer. The router should provide a routing algorithm and realize the best function of the packet, so it is located in the third layer of the network layer.

4. The functions are different.

Today's cats have both the functions of a router, being both a cat and a router.

5. The installation position is different.

In terms of installation location, the installation location of the optical modem is generally at the entrance of the optical fiber at home, while the router needs to have a network port nearby, and the other end of the network port is to be connected to the optical modem. For individual households, the router is generally placed in the place where the family can cover the largest area and has excellent signal reception, such as the living room**, bedroom, study, etc.

Precautions for using routers:

1. First of all, all routers will be optimized before leaving the factory, and you can access the Internet with simple installation, so if you don't have special needs, you don't need to make other changes. And in order to prevent others from abusing the bandwidth, you can also turn on the router's traffic control function.

2. Secondly, when installing the router, it should be noted that there should not be too many obstacles around the location, try to place it in a high and wide place, and it should not be too close to other wireless devices, such as microwave ovens and other equipment, otherwise it will cause interference to the router. At the same time, if you find that the network connection of the wireless computer finds excess signal information, you should also delete it.

3. Then, in order to avoid the compatibility problem of wap, for example, if there is no signal or drop in wireless, you can update the wireless network card, and if the wireless function of the router is not properly set, it will also affect the network operation. It is recommended to update and optimize in a timely manner.

The differences between a router and a cat are as follows:1. 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.

2. 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.

3. 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.

In principle, this is the case, but something else:

Cats are modems that are mainly used for signal conversion

Router - Implements the routing of data and **.

The differences in use are:

The cat is used to access the Internet through the ** line (including ADSL broadband and ordinary** line to the Internet), while the router is used to set up a local area network (including wireless and wired), and can also be used with the cat to achieve a ** line and multiple computers to access the Internet at the same time.

The router is used to divide a network cable into several computers on the device, if you are ** line to the Internet, you need to use a cat, if several computers use a ** line to connect to the Internet then connect to the cat and then connect to the router.

Do you know the difference between a router and a cat? If you don't know, then hurry up and take a look at the following article!

Routers: One of the functions of routers is to connect different ones'Another role of the network is to select the route of information transmission. Choosing a smooth and fast shortcut can greatly improve the communication speed, reduce the communication load of the network system, save the network system resources, and improve the smooth rate of the network system, so that the network system can play a greater role.

Optical modem: Optical modem, also known as single-port optical transceiver, is a three-piece optical fiber transmission equipment developed for special user environments. The device adopts a large-scale integrated chip, simple circuit, low power consumption, high reliability, complete alarm status indication and perfect network management function.

There is a big difference between the ports and form factors of routers and cats

The form factor and port of the router (wired routers and wireless routers).

Note: Routers are divided into wired routers and wireless routers, wired routers are most common with 4 ports and 8 ports: wireless routers are most common with 4 ports; There are obvious antennas as identification signs.

Cat profile with ports

There are two commonly used cat ports: one is connected to ** wire, and the other is connected to RJ-45 port (network cable).

There is also a cat with a router function (router and cat as one), this is relatively rare, this cat has the dual characteristics of cat and router, there are more ports, a wire, four network cable interfaces.

What is a cat?

The cat's meow is called a modem, and the computer can dial up the Internet through it.

What is a router?

The role of the router is to make several computers access the Internet at the same time with a network cable, which plays a role in allocation. Connect the cat on the top and the computer on the bottom.

The ports are different:

1) Wireless routers are most common with 4 ports, with obvious antennas as identification marks;

2) Two kinds of ports for cats: one for ** line and one for RJ-45 port (network cable);

Difference Between Cat and Router What is the difference between a cat and a router.

The connection is different:

1) Cat connection ** cable and (router or computer);

2) The router connects the cat and the computer via wired or wifi.

The settings are different: (1) the cat basically does not need to be set;

2) The router is set up through login, which is a bit complicated.

The differences between routers and cats are: different shapes, different functions, different ports, different connections, different settings, etc.

1. The shape is different.

The cat does not have an antenna, it is connected to the fiber through the port, whereas the router has an antenna, and it transmits the signal source through the antenna.

2. The role is different.

The router can distribute the network signal to multiple computers, mainly playing the role of distribution. The cat plays a modulating role for the network, and without it, the computer will not be able to dial up the Internet normally.

3. The wide port is different.

Wireless routers are most common with 4 ports, with obvious antennas as identification marks. There are two kinds of ports for cats, one for the ** cable and one for the network cable.

4. The connection is different.

The cat connects the ** cable to the router or computer, while the router connects the cat and the computer via wired or wifi.

5. The settings are different.

The cat basically does not need to be set up, and the router logs in to the setting through the router background, and the process is a bit complicated.

With the optical modem computer, dial-up Internet access can be carried out, and the router is just a device that helps multiple computers to share a network.

Optical modems usually have only two ports, while routers usually have four or more ports. The modem does not require any settings after activation, and the router can only be used after logging in to the settings. One end of the modem is connected to a ** cable, and one end is connected to a computer or router, while one end of the router is connected to a modem, and the other end can only be connected to a computer.

Difference 1: The role is different.

Internet access must have a light mu shed He cat, with a light cat computer to dial-up Internet. But you can access the Internet without a router, which is just a device that helps multiple computers share a network.

Difference 2: The ports are different.

The shape of the optical modem and the router is very similar, which is one of the reasons why we can't tell the difference. However, there is a big difference between them, and that is the port. Optical modems generally have only two ports, while routers have more ports, usually four.

How to use the wireless router

Step 1: Please link the device as shown in the figure below, power is the power supply) LAN is the output port, WAN is the network cable plug in port, and RESET is the reset button (hold down the sharp object for 5 seconds when you need to reset).

Step 2: After the connection is completed, check the running status of the indicator light. The sys system status indicator should be flashing, the 1 2 3 4 LAN status indicator should be solid or flashing at the corresponding light of the LAN end of the computer and the base port, and the WAN status indicator should be solid or flashing.
