Original Address http://www.dzsc.com/data/html/2011-1-17/88338.html1 IntroductionIn distributed systems, a global time is often needed to determine the sequence of events in the system, to coordinate the transmission of various messages, and to control and monitor the state of the system. It is necessary to unify the local time of each part in the system and clock synchronization. With the widespread application of distributed simulation system and te

Android USB Connections Explained:mtp, PTP, and USB Mass StorageOlder Android devices support USB mass storage for transferring files back and forth with a computer. Modern Android devices use the MTP or PTP protocols-you can choose which one prefer.To select a USB connection protocol, open the Settings app, tap Storage, tap the menu button, and tap USB computer Connect Ion. You'll also see the protocol you

1.PTP ModelsThe PTP (point-to-point) model is queue-based, and for the PTP message model its message is intended to be a message queue (queue), and the message producer always sends the message to the message queue each time it is sent. Message consumers always read messages from the message queue. Advanced Queue messages are first read by the message consumer.Th

Ptp: Image transmission protocol abbreviation, all called: Picture Transfer Protocol; PTP is one of the earliest standards developed by Kodak and Microsoft, which conforms to this standard, which can be better shared by systems and applications after accessing the Windows XP system, especially in the network transmission, the system can directly access these devices used to set up the network album image U

1.PTP Models The PTP (point-to-point) model is queue-based, and for the PTP message model its message is intended to be a message queue (queue), and the message producer always sends the message to the message queue each time it is sent. Message consumers always read messages from the message queue. Advanced Queue messages are first read by the message consumer.

NTP, Network Time Protocol, is a time synchronization protocol defined by RFC 1305 that is used to synchronize time between distributed time servers and clients. NTP is transmitted based on UDP packets, using a UDP port number of 123. The purpose of using NTP is to synchronize the clocks of all devices with clocks within the network so that the clocks of all devices within the network are consistent, allowing the device to provide multiple applications based on uniform time. For local systems ru

architecture emerged, so JMS came out. Here, we use Programming to Implement message transmission in the PTP model. Of course, either model is inseparable from the message server. Because the server is based on the weblogic12c server, and the version of 12 has changed significantly compared with the previous version, to create a queue, you must first create a JMS module.

First look at a STM32 clock system block diagram In STM32, there are five clock sources, namely HSI, HSE, LSI, LSE, PLL. HSI internal high-speed RC oscillator clock, 8mhz;hse, external high-speed clock, 4M__16MHZ;LSI, internal low-speed RC clock, 40KHZ; LSE external low-sp

1.Q: What is the system clock. What is a clock system. A: Usually referred to as the system clock refers to the clock system, which is the oscillator (signal source), timing wake-up, frequency divider and other components of the circuit. The commonly used signal sources are crystal oscillators and RC oscillators. 2.Q
