Passive Optical Networks are still commonly used. So I studied the comprehensive comparison between ATM Passive Optical Networks and passive optical networks. I would like to share with you here, hoping to help you. Passive Optical Network (PON) is an attractive pure media network. Its main feature is to avoid the elec
This article is about the error of the question.So what's the next thing to happen to this mistake?由于浏览器必须要在执行事件处理函数之后,才能知道有没有掉用过 preventDefault() ,这就导致了浏览器不能及时响应滚动,略有延迟。 所以为了让页面滚动的效果如丝般顺滑,从 chrome56 开始,在 window、document 和 body 上注册的 touchstart 和 touchmove 事件处理函数,会默认为是 passive: true。浏览器忽略 preventDefault() 就可以第一时间滚动了。 举例: wnidow.addEventListener(‘touchmove‘, func) 效果和下面一句一样 wnidow.addEventListener(‘touchmove‘, func, {
Passive changes are always passive.

People who do not know how to change will only fall deeper and deeper into the crisis until they reach the upper limit.
The tragedy of ordinary people is that they only want to suffer in the known field, and never have the courage to explore in the unknown field. However, real wealth, happiness, and freedom exist in
Active mode and passive mode of FTPThe FTP server communicates with the FTP client using 20 and 212 network ports.The FTP server's 21 port is used to transfer FTP control commands, and 20 ports are used to transfer file data.FTP Active Mode:The FTP client sends the connection request to the FTP control port of the server (by default, 21), the server accepts the connection, establishes a command link, and when the data needs to be transferred, the clie
Active mode
1. FTP Client use TCP Port 1026 for command to FTP Server command port 212. FTP Server use TCP port responed to FTP client command Port 10263. FTP Server use TCP port of sending data to FTP client data port 1027 (1026 + 1)4. FTP client use TCP port 1027 (1026 + 1) for data ACK to FTP server Port 20

Crystal oscillator from the material can be divided into quartz crystal oscillator and ceramic crystal two categories, and from the properties of crystal oscillator can be divided into passive crystal and active crystal oscillator. Quartz crystal and ceramic crystal vibration from the appearance of very advantageous to distinguish, after all, is also two completely different materials. and the passive cryst
The concept of a passive interface is to prevent routing updates from being sent from that interface. All IP-based routing protocols other than BGP can use the passive interface. One, using the passive interface in RIP1, the purpose of using the passive interface in some network environment, we do not want to send RIP

As for the concept of passive optical network, the PON standard based on ATM was proposed in early the 1980s, and the corresponding g.983 suggestion was defined by Itu/fsan, namely Apon. The author also participated in the meeting of the National TNS Optical Devices Working Group at the end of last year, and participated in the review of the communication industry standard of "ATM based passive optical netw

How does entering passive mode appear during FTP connection? One of the most common challenges when dealing with Firewall and other network connection problems is the difference between active FTP and Passive FTP and how to perfectly support them. Fortunately, this article helps you clear some confusion about how FTP is supported in the firewall environment.

Many people may not have a special understanding of configuring the dynamic Router Protocol. Here we mainly introduce the Passive-interface command in the dynamic Router Protocol, and managing network bandwidth is becoming more and more important. In a network without other routers, it is meaningless to route the Broadcast Communication outbound from the network interface. This is very inefficient for your network bandwidth and vro resources.
