The most basic function of JavaScript in a Web page is to listen to or respond to a user's actions, which is very useful. The user's action some very high frequency, some very rare. Some listener functions execute like lightning, and some heavy drag will kill the browser. In the case of the Resize event in the browser window, this event triggers once for each scale change in the browser window size, and if the listener volume is large, your browser wi

collection and processing technology to build a security monitoring network. The public network wireless (3G/4G) and Mesh Wireless LAN data transmission channels are used to transmit environmental data, alarm data, and video data, real-time online monitoring of the surrounding conditions of overhead transmission lines, towers, and towers. The combination of solar, wind, and energy storage batteries enables uninterrupted power supply around the clock

, which in the past two years has launched several rounds of tenders for td-lte equipment, and has opened a network of experiments in more than 10 cities in China. But even so, the 4G license plate guessing mystery or in the river of suspense tapered, the industry in addition to several operators and 4G standard back and forth to do radish and pit collocation, still did not give a convincing answer. The dou

significantly saving cost. WiMAX networks have many advantages over traditional broadband systems. For example, the WiMAX network is extremely flexible and can achieve hybrid connection between wired and wireless services. Because WiMAX networks do not require fixed lines, the investment required to deploy a WiMAX network is only 1/3 of the total investment of deploying a wired network, and the network deployment time and operation and maintenance costs can be reduced, therefore, it helps impro

4G war re-ignited China Unicom "fight" and mobile "drunk" The language "from the masses to the masses" does not seem so useful in the communication field. But the good news is that the "high" operators have been gradually "observing people's sentiments" and launched a lot of services for the people. Whether it is "toilet paper delivery, dial 10086", "one-stop service" of 10010, or the campus package of China Telecom, It is favored by many users, and

February 3, 2011. Insufficient address seriously restricts the application and development of Internet in many countries, so it is imperative for IPv4 to transition to IPV6. But in terms of quantity, if IPv6 become the mainstream of the Internet domain name distribution system, DNS (domain name resolution System) to deal with the data is more, although IPV6 solves the problem of network address and resources, but also the problem of maintaining security is more complex. In addition,

By reading msdn, you can use PAE to access more physical memory. However, for a specific 32-bit process, the addressing space is still 4 GB. During the process execution, I don't know how to map this 4G memory Where is the physical memory? The cpu mmu is responsible for ing the 4G process address space to the physical memory area with the PAE extended addressing, but through awe on Windows or MMAP in Linux,

Which of the following is the best 4G technology? Clarify the relationship between FDD and TDD (1) 1. Technical aspects: they are all born with a mother-in-law. The technical differences between FDD and TDD are actually very small. The main difference lies in the adoption of different duplex modes. FDD and TDD are two different duplex modes. FDD is used to receive and send messages on two separated symmetric fre
