can write it Criterion ? If so : If not In this way, you will understand more about this. 　 Let's introduce the logical operators ,! | ^ These four logical operators represent non, And, or, respectively. If you have never touched the set theory before, the explanation of the three operators may involve a lot of effort, so I will not give them a detailed explanation. I just want to give a brief introduction to the logic circuit (in fact, this is also very troublesome ), there are three operator

in a timely manner, and improve the wireless network in your home. 3. Correctly place the router location Another problem also affects the wireless network speed, which is greater than that of hardware, that is, the placement of routers. In fact, there is still a lot of attention to the placement of routers, because the wireless signal strength will continue to decline with the distance, especially in the case of obstacles (physical walls, so when your bedroom or home is too far away from the r

for networking. Since personal decoration is generally promoted by decoration companies, the sales can be achieved relatively high, so there are generally more functional requirements for the family, the number of points of implementation is also more. At this time, there are also requirements for system reliability and scalability. Because wiring is not a big problem at this time, the home decoration market should try to adopt star and bus methods. The old house transformation market generally

under the floor or decorative board, and the information socket should also be embedded, bury the bottom box in the wall. 3. Simple Design Because the number of information points is small, it is very convenient to manage, so home wiring does not need to use distribution frames. One end of the twisted pair wires is connected to the information outlet, and the other end can be directly connected to the wire set device, saving money and reducing management difficulty. 4. Proper Redundancy The s

, you can also look at other people's comments on the chip (the level of comments is high and low, different purposes, cannot be completely trusted ). Evidence 2: memory capacity Statement: "I have 16 MB of memory. You can see that it is only 8 MB, and the performance is much better than it. " Misunderstanding: This sentence has two traps. One problem is that memory is also an important component of a broadband router. Like a processor, the performance of a vro with low memory usage is not good,

Speaking of the chassis, this time we do not recommend the dark rack-mounted server chassis. What we use at home still requires the beauty of some household appliances. This is a small PC chassis with a white piano paint surface, with the silver front panel border, it is very elegant, small, very delicate, and has the feeling of Home Appliances. Although the chassis is not big, the large motherboard that ca

different from other household electrical appliances. other electrical appliances are loads. For example, if the power of the water heater is 1500 W, 1.5 kWh of electricity will be consumed in an hour. Misunderstanding 4: The rated power is enough. Most people are used to calculating the overall power consumption of the platform when purchasing power supplies, and then setting aside about 50 W of redundanc

card of the PCMCIA Interface does not have this problem. Wireless LAN faults: The system crashes after the wireless PCMCIA Nic is unplugged. Cause and solution: Generally, this type of operation is caused by non-standard operations. The standard operation sequence is to first disable the device in the PCMCIA Nic attribute, and then unplug the device. Or select "pop-up Device" and unplug the NIC. Wireless LAN faults: If you purchase a new wireless network device, it is often abnormal when you ch

consider the environment when selecting the placement location. Keep the route away from cordless phones and microwave ovens as much as possible. In addition, it can even be used in air conditioners, washing machines, and refrigerators to avoid electromagnetic interference or disconnection. Due to the special nature of the wireless network signal, we have to consider the environment when installing or deploying the network. In the family, the main devices that can affect wireless networks inclu

homes can connect electrical appliances in consumer homes with a wireless network, so that various audio and video information can be transmitted and exchanged between these electrical appliances. The Application of uwb wpan Technology in the digital office can connect all electronic office equipment via wireless networks, saving the trouble of wiring and making the office environment more convenient and f

communication devices and computer devices to connect to the Internet without using cables, and enable wireless Internet access, its practical application scope can also be expanded to various household appliances, consumer electronic products and information appliances such as automobiles, forming a huge wireless communication network. Bluetooth is a short-distance, low-cost wireless connection technology

, are the application of this principle.　　Dependency inversion Principle (DIP) – dependency inversion principleHigh-level modules should not rely on the implementation of low-level modules, but rather on high-layer abstractions.For example, the wall switch should not rely on the switch implementation of the lamp, but should rely on an abstract switch standard interface, so that when we extend the program, our switch can also control other different lights, and even different electrical

Internet of things "strong centrality" and "intelligent control" mode, has emerged in the smart home scene: On the one hand through the mobile phone collection and analysis from smart home and smart home appliances and other equipment data, on the other hand, based on the results of data analysis and reverse control of smart home and intelligent home appliances and other equipment, to optimize the family e
