What is a fool switch? It is easy to understand the introduction is not to take care of its switch, connected to the network equipment can be used.
With the development of modern society, the modern "lazy person" also more and mo
Often see network friends in the difference between the switch and router, in fact, if you have used both switch and router friends should know, for everyone, switch and router use the biggest difference is that the router can realize dial-up internet access, and then shared to multiple computers at the same time the I
broadcast all the ports.
The continuous cycle of this process, for the whole network of MAC address information can be learned, the second-tier switch is to create and maintain its own address table.
Characteristics
From the two-layer switch can be inferred from the operating principle of the following three points: (Small series recommended:
Experts tell you what a layer-3 switch is. Now every household has their own computer and understands what a layer-3 switch is. At that time, the layer-3 switch was based on software an
In the early 90, with the improvement of computer performance and the increase of traffic, traditional LAN has more and more exceeded its own load, switching Ethernet technology came into being, which greatly improved the performance of LAN. The two-tier switch plays a key role in the development of the switch technology, but with the maturity of the two-layer switch
The core switch adopts the distributed CrossBar and distributed switching architecture to solve the large-capacity switching problem. Currently, all switches support full duplex. The advantage of full duplex is low latency and high speed, the following is a description.
Applications are always the driving force behind technological development. In the face of inc
Many friends more on what is Poe Switch memory Switch Poe feature is not very well understood, the following system is introduced.What is Poe?Power over Ethernet (PoE)
Spring Parent-child relationships. Spring MVC corresponds to a context that is a child context of spring and can access properties in the spring context.Reference: https://www.cnblogs.com/huntdream/p/6012390.html The so-called traditional type, is the action, service, DAO Three layer architecture, based on the complex business of large company development model.For this mode, the general spring context
ears? Moreover, the software uses a MIDI device to play the video, ensuring that there is no deviation in the sound accuracy. It can also calculate your accuracy rate! 10. Fruity loops may be a headache for editing drums and percussion voices? The pace of Self-editing is either fragmented and uncentered, or lacks changes. In addition, drums in the sequencer software cannot hear the effects of loop repetiti
Step 1 in the online world: what is an Ethernet switch? a switch in the broad sense is a device that completes information exchange in a communication system. Of course, we have already popularized programmable switches, and the exchange process
Often have friends to consult the most fire software station small series, about the difference between switches and routers, in fact, if you have used the switch and router friends should be aware of, for everyone, switches and routers in the use of the biggest difference is that the router can achieve dial-up Internet, and then through sharing to many computers at the same time online, But the
What is the function and working principle of fiber Switch fiber switch: Fiber Optic switch is a high-speed network transmission relay device, which uses fiber optic cable as transmission medium compared with ordinary
The second-tier switch and the third-tier switch are end-to-end Exchange processes based on port addresses, although this kind of switch technology based on MAC address and IP address can greatly improve the data transmission rate between the nodes, it cannot determine or dynamically restrict the exchange process and data flow of the port according to the applica
in detail the differences between switches and hubs through theories and instances. To sum up, this article fully discusses the differences between vswitches and hubs from the outside to the inside, from the surface to the essence.
In today's global network era, networks have become essential for human life. As an important device for LAN Construction: switches and hubs play a "pivot" for LAN data transmission. So what
What is the difference between an interface and an abstract classWhat is the basis of your choice to use interfaces and abstract classes?The concepts of interfaces and abstract classes are different. An interface is an abstraction of an action, and an abstract class is an ab
1. The clock period is equal to the reciprocal of the single-chip crystal oscillator frequency. For example, if a common external 12 m crystal oscillator is used, the clock period is 1/12 m.2. machine cycle: 8051 series single-chip microcomputer machine cycle = 12 * clock cycle, this is because a single clock cycle can

What is open collector (OC )?
Let's talk about the structure of open collector output. As shown in structure 1 of open collector output, the transistor on the right has no collector, so it
to the case value, and if the result is directly output if it is equal to the value of the instance, break in PHP switch is used to directly block the next case code from running. If the above $like equals singing, then output the CASE1 value directly. (You can refer to the online tutorial: "PHP QuickStart Free Tutori
In the WIN8 system, we can directly switch the local account to the Microsoft account, so as to achieve the sharing of the account network.
