Now, Gigabit Networks are becoming more popular, but the practice of Gigabit Networks is not widely understood by many friends. Hope to help you. The gigabit 5 category or over 5 category twisted pair wires are in the same form as the 10-Gigabit network cable. They are also divided into two types: pass-through and crossover. The straight-through network cable is exactly the same as what we usually use. However, the traditional 10-Gigabit network only

Whether you like it or not, Software Diagrams such as the Unified Modeling Language (UML) model and use case model often determine their quality based on their appearance. Neat charts are more favored by readers-often your users or senior managers-than messy ones. I would like to describe several important empirical rules that will make you better than other modeling colleagues. These simple but key suggestions mainly focus on the boxes and lines that make up Software Diagrams (including UML

not, enable the file sharing function. Otherwise, NFS can be mounted but cannot be accessed. I encountered this problem when setting it. I was depressed for a long time. ^ _ ^3.

The serial cable can be divided into straight chain and intersection. Generally for straight line extension PC equip, will 2, 3, 5 connect 2, 3, 5, because PC universal male. But the devices are mostly female, so they are just plain, and it can also be used to extend the connection; the crossover PC is connected to the PC with 2 pairs of 3, 3 pairs of 2, 5 to 5, and the general two are female at both ends!Before the computer appeared, the EIA establis

the end of the conversion of the regular channel, and the transformed data is transferred from the ADC_DR register to the user-specified destination address.Note: Only ADC1 and ADC3 have DMA capabilities. The data converted by ADC2 can be transmitted using the DMA function of the ADC1 via the dual ADC mode.5. Dual ADC Mode(1) Synchronous injection mode: This mode converts an injection channel group. External triggering of the injection group multiplexer from the ADC1 (selected by the jextsel[2:

network segments are isolated. To connect to the Internet, a layer-3 switch that supports 802.1Q VLAN is required. when data is sent out, the VLAN Tag is stripped and the IP address is forwarded to the correct VLAN subnet when data is received. The router performs NAT translation based on the IP address to connect to the Internet.Figure 7. Virtual network B _V0 Figure 7. Virtual network B _V0 Network B can be accurately simulated under virtualization conditions. The six virtual machines will se

The serial line also points through and crosses, pass-through is generally used to extend the PC and equipment, will be 2, 3, 5 respectively connected 2, 3, 5, because the PC is generally male, and the device is mostly female, so just they are universal, can be used for extension can also be used for connection; crossover is generally used for PC docking with PC, 2 to 3, 3 to 2, 5 to 5, usually both ends are female!Before the computer appeared, the EI

values of each chromosome, the best chromosome is selected and the optimal solution is obtained.Simply put, is to give you a bunch of people (and population), let you choose a part of the gene fine (the solution of higher fitness, such as greater value) of the people come out, let them have children to form offspring (choose crossover and mutation), these descendants and previously selected parents, then compare the gene fine, then choose, then inher

Genetic algorithm --- stochastic algorithmThe genetic algorithm (genetic algorithms,GA) was first made in 1975 Year by the American University of Michigan D . J. Professor Holland and his colleagues drew upon the principles of natural selection and Mendel's genetic evolutionary mechanisms in the biological world. After nearly Five years of research and application, genetic algorithm has been widely used in function optimization, robot system, neural network learning process, pattern recognitio

The port of the core switch is mainly a fiber type, but the price of the switch fibre port is very expensive and requires special attention from the user, while the fibre port of the switch is not stacked and can only be used for cascading purposes. Cascading can use either a normal port or a special mdi-ii port. A pass-through cable should be used when the two ports that are cascaded are normal (that is, mdi-x) and Mdi-ii ports. You should use a crossover
