The new Snapdragon 835 processor supports Quick Charge 4 fast charging, which increases charging speed by 20% and increases charging efficiency by 30% compared to Quick Charge 3.0. In addition, it has a smaller chip size and provides a more flexible interior space design for mobile phone manufacturers. Quick Charge 4.0 fast charging technology can extend the use of mobile phones for 5 hours by charging for 5 minutes. In addition, QC 4.0 also integrates support for USB-C and USB-PD (Power Delivery) for a wider range of adaptations. Qualcomm did not disclose more information about the Snapdragon 835, but said that the 10nm process will bring better performance and improve power efficiency, compared to the Qualcomm Snapdragon 820 based on 14nm manufacturing process. Samsung said that the 10nm process will make the chip faster by 27% and the efficiency up by 40% compared to 14nm. The Snapdragon 625 is Qualcomm's first eight-core processor built on a 14nm process, which is the same process node as the Snapdragon 820 and also supports Quick Charge 3.0 fast charge technology. Although the Snapdragon 625 is part of the Snapdragon 600 series, the Snapdragon 625 uses the latest generation of 14nm process technology, which saves 35% compared with the previous generation Snapdragon 617 and is equipped with eight Cortex-A53 processing cores. The main frequency is up to 2GHz. The Snapdragon 625 processor uses an advanced 14nm process technology. In contrast, the Snapdragon 652, which is also positioned at the mid-end, still uses the old 28nm process. It can be seen that the Snapdragon 625 has a natural advantage in terms of heat generation and power consumption control. This year's mobile phone is already doomed to be extraordinary. Let's first say that the mobile phone's strongest processor is the Snapdragon 835. At present, playing a game, there is no éªé¾™ 835, I dare not test it. Now The mobile phone, only the strong performance can speak, but although the performance of the Xiaolong 835 can be strong, but the power consumption is still quite serious, after all, experience there. Speaking of power consumption, perhaps the processor of the Snapdragon 625 has more say. Although the performance of this processor is not as strong as that of the Snapdragon 835, its long-lasting ability is still very powerful. After all, power consumption is there, maybe many people will I feel that the performance is not strong enough, the power consumption is definitely low, in fact, it is very reasonable. Let's take a look at the two mobile phones with similar prices, and carry these two processors respectively. What is the magical place? Let's take a look at the price first. I started talking about Xiaobian. The prices of these two mobile phones are very close. The price of Xiaomi 6 is 2,499 yuan, while the price of VIVO X9 is 2,598 yuan. The price is almost the same, of course, whether it is The sales strategy is still the main product. The two mobile phones have a slightly different route. VIVO prefers to sell offline. From the front, the two styles are close, the design is round, on the screen, the Xiaomi 6 uses a 5.15-inch eye screen, while the vivo X9 uses a 5.5-inch display screen. The size difference is not obvious, both sides are 1920 & TImes; 1080 resolution, and the border control is very good, no obvious black edges, the value is still very high. Configuration: Xiaomi 6 can be said to be the most cost-effective mobile phone, and the cheapest Snapdragon 835 mobile phone, 6GB storage and 64GB flash memory, the price is really surprisingly high, and VIVO X9 is equipped with Snapdragon 625 processing With 4GB of memory and +64GB of flash memory, there is nothing to say about the performance configuration. I believe everyone has a result in mind, one is pursuing performance and the other is pursuing practicality. On the system, Xiaomi 6 is equipped with the latest MIUI system based on Android 7.1.1, while the vivo X9 is Funtouch OS, the style will be different, but the actual daily use is smooth, but the current system can be said that the level is getting more and more High, I don't know when, Xiaobian's red rice Note4X can be upgraded to install 7.1. In terms of the front camera, Xiaomi 6 is quite satisfactory. It chooses a single lens of 800W pixels to support the third-generation 36-level intelligent beauty technology, while the vivo X9 is more bold. As the main selfie, it has added the design of the dual front camera. The main camera is 2000W pixels, and the sub-lens assisted by the depth of field is 800W pixels. For the girls who like to take selfies, the vivo X9 is more tempting. On the rear camera, Xiaomi 6 adopts the latest zoom dual-camera solution, wide-angle + telephoto dual 1200W lens, the blur effect of the portrait mode, making people more beautiful, while the vivo X9 is a 1600W pixel single. The lens is less playable. Battery, millet 6 is 3350mAh, vivo X9 is 3050mAh, millet 6 slightly superior in terms of battery life, of course, millet 6 canceled 3.5mm headphone jack, and vivo X9 still supports HiFi sound, I don't know how you look. Although the prices of these two mobile phones are not much different, the processors are different. I don't know, everyone will spend almost the same amount of money and buy a mobile phone.
The task of the managed switch is to keep all network resources in good condition. The network management switch product provides a variety of network management methods based on the terminal control port (Console), based on the Web page, and supports Telnet to remotely log in to the network. Therefore, network administrators can perform local or remote real-time monitoring of the switch's working status and network running status, and manage the working status and working mode of all switch ports in a global view.
The switch is the most important network connection device of the LAN, and the management of the LAN mostly involves the management of the switch.
There are also managed switches that provide policy-based QoS (Quality of service). Policy refers to the rules that control the behavior of the switch. The network administrator uses the policy to allocate bandwidth and priority for application flows and control network access. The focus is on the bandwidth management strategy required by the service level agreement and the way of publishing the policy to the switch. Multifunction light emitting diodes (LEDs) used to indicate port status, half duplex/full duplex and 10BaseT/100BaseT at each port of the switch, and switch status LEDs that indicate system, redundant power supply (RPS) and bandwidth utilization A comprehensive and convenient visual management system has been formed. 1U Industrial Switch,L3 Ethernet Switches,24 Port Managed Switch,Managed Industrial Switches Shenzhen Scodeno Technology Co.,Ltd , https://www.scodenonet.com
The network management switch supports the SNMP protocol. The SNMP protocol consists of a set of simple network communication specifications, which can complete all basic network management tasks, has a small demand for network resources, and has some security mechanisms. The working mechanism of the SNMP protocol is very simple, mainly through various types of messages, namely PDU (protocol data unit) to achieve the exchange of network information.
