Ask about the knowledge of switches and the way switches are exchanged

Scold. The switch works in much the same way as the wire collector you are talking about.

At the top end is the router. At the bottom is the switch. This switch also doesn't need to be set up at all. As long as the router is set up with IPOther computers can be connected to the switch.

However, there is a network cable between this routing and switching"Cross-cable"with"Straight cables"The difference. Some require cross-cables. Some require a straight cable. All in all, it's pretty simple.

Now there are also 8-port and extra-large 16-port routers. If you want to make it easier or more convenient, just change to a multi-port route.

Generally, the switch you buy back can be used as a hub without any settings

The switch is only technically different, the switch data is transmitted from port to port, and the hub is broadcast to all ports for transmission Hehe For you, the switch has a great advantage over the hub to transfer files between 10 computers

If you buy a normal switch (not managed or higher), the use is the same as the hub, so to speak, there are only benefits and no harm.

Switches on port switching suppress some broadcast storms.

The main feature of the switch is the VLAN function, and nothing is equipped with VLAN1 to work.

Different hosts can be assigned to different VLANs.

Network equipment for electrical signals**.

A switch is a type of network equipment used for electrical signals**. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common type of switch is an Ethernet switch. Other common ones include voice switches, fiber optic switches, etc.

In actual use, the Ethernet switch generally does not need both sides of the communication to send and receive at the same time, such as a one-way transmission device such as a printer, half-duplex or even simplex can be competent, and there is no need to reverse the one-way transmission equipment such as a printer, half-duplex or even simplex can be competent, and there is no need to reverse the direction. Here are the switches I brought to exchange in the following three ways:

1.Straight-through:

A pass-through Ethernet switch can be understood as a line matrix switch that crosses each port vertically and horizontally. When it detects a packet at the input port, it checks the header of the packet, obtains the destination address of the packet, starts the internal dynamic lookup table and converts it into the corresponding output port, connects it at the intersection of input and output, and passes the packet directly to the corresponding port to realize the switching function.

Since it does not require storage, it has very low latency and very fast switching, which is its advantage. The disadvantage is that because the packet content is not stored by the Ethernet switch, it cannot check whether the packet being transmitted is incorrect, and it does not provide error detection capabilities. Since there is no cache, input and output ports with different rates cannot be directly connected, and packet loss is susceptible.

2.Storage**:

The storage method is the most widely used method in the field of computer networking. It stores the packets at the input port first, then performs CRC (cyclic redundancy code check) checking, and only then takes out the destination address of the packet after processing the error packet, and converts it into an output port through the lookup table to send the packet.

Because of this, the storage mode has a large delay in data processing, which is its disadvantage, but it can error detect the data packets entering the switch and effectively improve the network performance. In particular, it can support conversion between ports of different speeds, keeping the high-speed and low-speed ports working together.

3.Fragment isolation:

This is a solution that falls somewhere in between. It checks whether the length of the packet is 64 bytes, if it is less than 64 bytes, it means that it is a fake packet, and the packet is discarded; If it is larger than 64 bytes, the packet is sent. This method also does not provide data validation.

It processes data faster than storage**, but slower than straight-through.

Applications of Ethernet switchesIf you have a large number of users, busy applications, and a variety of servers on your Ethernet network, and you haven't made any adjustments to the network structure, the performance of the entire network can be very low. One of the workarounds is to add a 10 100Mbps switch over Ethernet.

Not only can it handle 10Mbps regular Ethernet data streams, but it can also support 100Mbps fast Ethernet connections. If the network utilization is more than 40% and the collision rate is greater than 10%, the switch can help you solve the problem.

Switches with 100Mbps Fast Ethernet and 10Mbps Ethernet ports can operate in full-duplex mode and can establish dedicated 20Mbps to 200Mbps connections.

1. The network cable cannot be directly connected to the router.

2. The landlord may have used the kind of router at home, and people just named him a router, but in fact, his function is to integrate the routing function and the switch function.

3. The router is to convert the IP address (the IP address given by Netcom or Telecom is converted into the IP address) 4. A wire from the router is connected to the switch, and the role of the switch is to separate a lot of wires (the principle of the switch is not much to say).

1.When to use the road.

Composed? Routes are required for communication between different network segments and different VLANs. Routes can be provided by routers or Layer 3 switches.

However, at this stage, high-level switches still cannot replace routers, and routers are generally needed at the network edge, which can provide a better network assurance mechanism than switches.

2.When is a switch used?

Layer 2 switches are mainly used in the access layer, that is, where there are terminal accesses, which can provide sufficient ports for users to use. Layer 3 can be used in some core networks because it has a very strong data exchange capability, which cannot be compared with routers.

3.How do the two work together?

Generally, it is connected to the switch under the router, and the router mainly plays the role of data, that is, the function of addressing and routing. The switch serves the purpose of user access.

4.How do I set up and use the two?

The switch is mainly divided into VLANs according to the requirements, and the router is mainly configured with routing and security protocols!

Routers generally have fewer interfaces, most of which have 4 ports, while switches have more 4-32 ports. The function of connecting computers.

Routers and switches function differently. **Different. The efficiency of processing data is different. Different equipment should be used according to different needs.

Routers are mostly used for WAN access and interconnection, it is based on IP address ** packets, its software and hardware are more complex, the cost is high, the same port and processing power in the case, ** is much more expensive than the switch.

Switches (layer 2 switches) are mostly used in the LAN, through the MAC address ** data frame, the data ** can be realized through the hardware, the same port and processing power, ** is much cheaper than the router.

Proper use of routers and switches can lead to the fastest network speeds at cost savings. For example, you can use a switch to connect to the computer within the organization, and you need a router to connect to the Internet. For home use, there are not many computers, so the two are often combined and a 4-port router is used.

Routers and switches used to have different functions, but now routing also has a switch function, and multi-port routing can make the routing of the switch expensive.

A switch, also known as a switching hub, is an important device in a local area network. It sends packets received by the user to the appropriate port based on the destination address**. It differs from a general hub in the following ways:

The hub is to send data to all hub ports, both computers in the same network segment share inherent bandwidth, and the transmission is carried out through collision detection, the more computers in the same network segment, the more transmission collisions, and the transmission rate will be slower; The switch has a fixed bandwidth for each port, has a unique transmission method, and the transmission rate is not affected by the increase in the number of computers, so it is better.

A switch is a data link layer device that connects multiple LAN segments to a large network. At present, there are many types of switches, and according to the architecture characteristics, switches can be divided into three types: rack-mounted, fixed-configuration with expansion slots, and fixed-configuration without expansion slots.

According to the application scale, switches can be divided into enterprise-level switches, departmental switches, and workgroup switches.

What is a switch and what is it used for? Used to exchange voice and data. The switch is to play the role of a data ** to give you a **, see if you are satisfied. Work on the data, nirthi

To put it simply, a switch allows you to use several computers with one network cable, and these computers can form a local area network between them. The main functions of the router and the switch are almost the same, but the router has a little more functions, you can set up automatic dial-up Internet access, and you can also have a wireless network with wireless function.
