arduino multiple switches

Currently, the relay distance between switches is greatly increased, which makes it possible for multiple switches with remote distribution and remote connection, and facilitates different networking solutions for users. The simplest LAN usually consists of a hub (or switch) and several computers. As the number of computers increases and the network scale expands

switchcontent (fragment) {If (mcontent! = Fragment) {mcontent = fragment; mfragmentman. begintransaction (). setcustomanimations (Android. r. anim. fade_in, R. anim. slide_out ). replace (R. id. content_frame, fragment) // replace fragment to implement failover. commit ();}} However, there is a problem:During each switchover, fragment will be re-instantiated to reload data on one side, which consumes a lot of performance and user data traffic. Just think about how to make

I. Question proposal: With the increasing number of computers in the school, more than 254 hosts are deployed on the network, and the IP address of a Class c Network (192.168.1.0) is insufficient. Although the lease period of IP addresses can be shortened, however, frequent IP Address requests may cause Network Information congestion, and too many computers in the same network segment may cause a broadcast storm. The center switch of our school network adopts the layer-3 Switch Alcatel Omnistack

This paper analyzes the set of VLAN division methods for multiple vswitches. VLAN implementation methods on vswitches can be roughly divided into six categories: VLAN division methods for vswitches Based on port division and VLAN division methods for MAC address vswitches. ◆ VLAN division of vswitches Based on port Division This is the most commonly used VLAN division method. It is also the most widely used and effective method. Currently, most VLAN-b

Problem:You need to switch fragment in your project, you can replace fragment with the Replace () method: public void Switchcontent (Fragment Fragment) {if (mcontent ! = fragment) {mcontent = Fragment Mfragmentman.begintransaction () .set Customanimations (Android .anim .fade _in, R.anim .slide _out) .replace (R.id _frame, fragment)//replace fragment, implement toggle .commit () } }However, there is a problem with this:每次切换的时候，Fragment都会重新实例化，重新加载数据，这样非常消耗性能和用户的数据流量。Solv

Android-multiple Fragment switches are not re-instantiated Problem:To switch Fragment in a project, you can use the replace () method to replace Fragment: Public void switchContent (Fragment fragment) {if (mContent! = Fragment) {mContent = fragment; mFragmentMan. beginTransaction (). setCustomAnimations (android. r. anim. fade_in, R. anim. slide_out ). replace (R. id. content_frame, fragment) // replace Fra
