Let s talk about whether I should buy a router or a router

He moved away You connect the network cable from ** If you run the network yourself, the cats are all sent If you still pull the network cable from someone else's house, people still have cats, so a router is enough.

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 saved in the router, and the routing table is used for route selection. 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. Based on the functions provided by the routing protocol, the router automatically learns and memorizes network conditions, and automatically calculates the best path for data transmission when needed.

In your case, you can't access the Internet when you buy a cat, so it is recommended to buy a router.

Buy a single router now!

Too many features are sometimes not a good thing, especially when operators such as telecom have requirements for cats!

The 1+1 mode is easy to manage!

The routing cat has a cat with a routing function, and there are no more interfaces, so it is equivalent to you buying a cat, and the general home router has 4 or 8 ports, which can pick up multiple people to surf the Internet together, but it does not have the function of a cat.

So you still have to buy a router, the kind of router with the function of a cat and a hub should also be available on the market.

wifi requires a wireless router, or needs a wireless routing cat, that is, an all-in-one machine, with the functions of a cat and a wireless router.

Cats and routing are different things, except that some cats have routing functions. The scientific name of the cat is modem, and its main function is to convert digital signals and analog signals. The function of routing is to realize the distribution of data packets.

In fact, if you want to use wifi, you only need to choose a device with wireless routing function, wireless routing is also OK, or cats with wireless routing function are OK. None is better, and of course if your cat doesn't come with wireless routing, you certainly can't choose a cat. The choice of cat or routing depends on the route taken by your home broadband, ** line will use cats, and you will not need cats directly to the home with broadband.

Cats and routers are two different things,The functions of the two are also different,Cats are used for broadband connections (of course, some broadband connections do not need to use cats,For example, I use Huashu broadband now),If you want to use wifi, you need to use a wireless router。

In other words, if you use a wire yourself, don't route it, wifi doesn't necessarily need to be routed, and most computers have virtual wifi function.

Yes, only routers can transmit wifi signals.

Cats and routers are two different functional things.

However, some cats are integrated with router functions and wireless functions, such as China Telecom's optical modem. At this time, you don't need to buy a router, you can use it directly.

If your cat doesn't have a router function and wants to surf the Internet wirelessly, it's best to buy a wireless router.

Of course, if you only want to use it for mobile phones, the laptop can also share a wireless network, but such a network is not easy to use, when you need to use a wireless network, the computer must be turned on, and the network must be shared.

A router and a cat are not the same, and the two have the following differences:

1. The difference in name definition: routers are divided into wireless routers and traditional routers (that is, routers connected by network cables), which are different from cats, which are called modems, while the commonly used optical modems on the market are actually called optical modems.

2. The difference between transmission signals: the router realizes data transmission by transmitting digital signals, while the cat (i.e. modem) is the converter of transmitting signals, which can convert analog signals into digital signals or convert digital signals into analog signals.

3. The difference between the wiring interface: In addition to the consistent power interface, the router and the cat are mainly network cable interfaces, and usually a router is equipped with 5 network cable interface slots. The cat is equipped with 1 or 2 network cable interfaces, and is equipped with ** cable interface and optical fiber data interface.

4. Functional differences: The router refers to the router, and its main function is to connect different networks and distribute connections, including the formation of LAN and WAN and other functions. The cat is a conversion instrument that transmits signals, therefore, the cat has a dial-up Internet function for users to connect to the Internet.

5. The difference in the number of layers of the OSI model: the OSI model has a total of seven layers, and the cat only converts the analog signal and the digital signal, and does not involve finding the path, so in the first layer of 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.

A router is not the same as a cat.

The computer needs to be connected to the internet and must use a router. A cat is a network signal switching device that transmits between different **.

Differences: 1. Different appearances.

2. Different uses.

The role of the router is about the redistribution of network signals, that is, through the use of routers, multiple computers can use the same network cable to access the Internet.

The function of the cat is to be able to transfer the network signals of different media, such as ADSL, light, wired communication and other different network signals through the cat to convert into standard computer network signals.

3. The number of ports is different.

Routers are generally 4-port and 8-port. The cat is generally 2 ports, and there are two access ports, one is used to connect the ** line, and the other is used to connect the RJ-45 port network cable.

Cats are the tools that turn data signals into network signals and thus convert them and routers are the tools that connect these signals.

The cat is connected to the Internet through the ** line, and now the cat is rarely used, and the router is only civil, and the router is actually just a cat with a routing function.

Basically, it is broadband to the home, if there are multiple computers, you can directly connect to the router.

Router routing function, you can build a small LAN, the cat is only dial-up Internet device, used to use ** online network, to connect to the cat first, the analog signal can be identified by the computer digital signal, so it is called a modem.

Now the router has integrated the function of the cat, you can set the dial-up on the router, instead of the use of the cat, direct access to the network cable can also be used, generally with several dial-up methods, such as ADS, PPOS for broadband Internet access, etc.

At present, it is already the era of network information technology, and the network is indispensable in our daily life, and auxiliary equipment such as cats and routers are often used when linking to the Internet. But there are still a lot of people who don't know what a cat is and what a router is. So,Is the router a cat

What is the difference between a router and a cat? Let me give you a detailed explanation. Let's find out.

1. Is the router a cat?

Is the router a cat?The answer is no.

Although they are all used for Internet access, but the cat is used for conversion, used for network signal transfer between different media between networks, the cat's name is modem, and the computer can dial up the Internet through it. For example, the cat used in telecommunications is mainly used for ADSL dialing, and only when dialing can you access the Internet; There is also an optical modem for large-scale networks, which is also used to convert optical signals to digital signals, and can be directly connected to the Internet.

The router does not need to be so troublesome and can be used directly for Internet access. Set up the router, and what arrives at the router is already a digital signal, so there is no need to convert it anymore. Routers are more secure than cats, because routers can also be used for some specific networks and prevent intrusions on the network.

In addition, it can also make several computers access to the Internet at the same time with a network cable, which plays a role in allocation.

2. What are the differences between routers and cats?

1. The ports of the two are different.

1) Wireless router: 4 ports are the most common, with obvious antennas as identification marks.

2) Cat: two kinds of ports, one is the first line, and the other is the RJ-45 port that is the network cable.

2. The use of the two is different.

1) Router: Through wired or wifi, the top is connected to the cat, and the bottom is connected to the computer. As mentioned earlier, the router can make several computers access the Internet at the same time with a network cable, that is, it plays a role in allocation.

2) Cat: The top is connected to the ** line, and the bottom is connected to the router. Dial-up Internet access is only possible when the computer passes through it.

3. The settings of the two are different.

1) Cats: Basically no need to set up;

2) Router: There are some complicated steps through the login settings, but the security is high.

4. In other words, the cat is equivalent to the packaging factory, and the router is equivalent to the wholesale retailer. Therefore, if you have broadband at home, you must have a cat, and if you want multiple computers to be able to access the Internet at the same time, you must have a router. If there are a lot of computers, more than the number of interfaces in the router, then you need a switch to link them.

And an introduction to what are the differences between routers and cats. In fact, people who can use computers may not be clear about these professional-level things, and most people install the network to ask professional technicians to configure, so through my understanding of the above information, I should have some understanding in my heart, and I should be able to distinguish who is who.

Routers and cats are common digital devices in everyday life, but many people think that routers and cats are the same thing. This is a big mistake, routers and cats are not the same, the computer needs to be connected to the internet and must use the router. The cat is a network signal switching device transmitted between different **, the actual function and specific parameters can not be confused, the difference between the router and the cat I will introduce to you in this celebration.

Form factor and port.

In addition to the different uses, the difference between the router and the cat also exists in the shape and port connection, there are currently two main types of routers, one is a wired router, and the other is a wireless router, the first time to use the router is a wired router, and the 4 port and 8 port routers are the most common. Wireless routers are generally 4 ports, and it is very simple to distinguish them, wireless routers have antennas. There are generally two kinds of cat ports, one is used to connect the ** cable, and the other is used to connect the RJ-45 port network cable.

Router. What is a router, the role of a router is about the redistribution of network signals, that is to say, through the use of a router, multiple computers can use a network cable to access the Internet. The existence of the cat is like a sub-assembly factory, and the existence of the router is equivalent to the offline wholesale retailer, so in daily use, if you want to use the broadband in the home, you must use the dispatch to the cat, if more than one computer needs to access the Internet, you must use the router, when the number of computers is too much, more than the original router interface, you must use the switch expansion port.

Cat. What is the difference between a router and a cat, first of all, let's talk about cats, the role of cats is to be able to transfer network signals from different media, such as ADSL, light, wired communication and other different network signals through the cat to convert into standard computer network signals.

However, there is currently a kind of cat with the function of a router, that is to say, using this cat is equivalent to using a router at the same time, although this integrated design is convenient, but it is relatively rare, but it can have two functions of router and cat at the same time, and there are more ports, with four network cable interfaces.

I believe we all know the difference between routers and cats, when installing network cables at home, the staff will directly install the cat, when installing a computer at home, you need to buy a router, these two are indispensable, with the use of wireless routers, it has brought great convenience to people, and more people have realized what a router is.
