HTTP-based breakpoint transmission and HTTP breakpoint Transmission
A file downloading function similar to thunder is required in recent projects. This type of requirement may be common and may be helpful to those in need.
Requirements:
1. Support for breakpoint Transmission
2. Simultaneous download of multiple files
3. Because it is an internal trial by the cust

Vue data transmission-I have special implementation skills, vue transmission-skills
Preface
Recently, I encountered many questions about the eventBus of vue. I was also asked about the applicability of vuex and eventBus when I set the technology selection. So let's just write it down. There is also a special implementation scheme.
There are several data transmission
Serialization: Converts an object to a buffer, obj---->buf
Deserialization: Converts the buffer into an object BUF--->obj
Program ape like obj, network transmission like BUF.
The well-known serialization, deserialization tool is Google protocol buffer, in the previous article, we have been contacted. Of course, many companies also have their own serialization and deserialization tools. We know that the nature of network
P2661 information transmission and p2661 Information TransmissionDescription
N students (numbered 1 to n) are playing an information transfer game. In the game, each person has a fixed Information Transmission object. Specifically, the information transmission object for students numbered I is Ti.
At the beginning of the game, everyone only knows their birthdays.
Description:Originally, one-way transmission of Streams was directly configured on two database servers,The original source database is two clusters of 64-bit HP-UNIX Oracle11gR2 database,The original target database is a 64-bit Linux Oracle11gR2 database,Now on the basis of the above, the Oracle11gR2 of a 64-bit Linux as the source database, the two clusters of 64-bit HP-UNIX Oracle11gR2 database as the target database,Install the one-way

Linux and Windows File Transfer implementation
I. Overview
When learning about Linux servers, we sometimes need to interact with files in Windows. How do we implement this? Today is my first time to write an article in the blog Park. At this time, when I was studying Linux, I would like to summarize how to use the file transfer tool
IOS-Safe Transmission of user passwords, ios-transmission of user passwords
Correct practice: generate a pair of public and private keys for encryption in advance. When the client logs on, it uses the public key to encrypt the user's password and then transmit the ciphertext to the server. The server decrypts the password using the private key, adds the salt, and then requests MD5 for multiple times. Then,
role of "Network remote control" for multimedia services. Although it is sometimes possible to interleave the RTSP control information with the media data stream, the general condition of RTSP itself is not used to transmit media stream data. The transmission of media data can be done through protocols such as RTP/RTCP.A basic RTSP operation process is:First, the client connects to the streaming server and
media transmission. After analog video and sound signals are converted to digital form by capturing devices, the data volume is amazing. If compression technology is not used, it is unimaginable to achieve network transmission of digital videos and sounds. On the other hand, digital video and sound transmission are highly time-sensitive and have high real-time r
Exercise caution when developing a UDP data transmission system between Android phones
TIPS:1. The communication between mobile UDP and a fixed IP is not a big problem, but it may also cause a slight packet loss. The problem cannot be found here. Do you think there are special considerations for UDP implementation at the android network layer.2. UDP communication between mobile phones and UDP is basically unreliable. Therefore, it is very unreliable t

This article mainly gives you a detailed introduction of the wireless router transmission speed of the reasons, gave a few analysis, here also introduced a number of settings program, I hope to see this article to help everyone. Many friends have found that our actual wireless router transmission rate is not as fast as the product introduction, what is the reason? Is it a false identification made by a me
Wireless LAN, also known as WLAN (Wireless LAN), has become a more and more users of the networking approach. Wireless network installation is very convenient, do not need to rewiring. So it will not destroy the original home decoration, compared to the cable network, wireless network is much more flexible.
In the use of the process, we found that although the WLAN does not have the trouble of wiring, and easy to use, but sometimes we will find its signal is not very stable, data
