BT server realizes file sharing through pyramid scheme, and its working principle. For example, if a BT server divides a file into n parts and four users A, B, C and D download it at the same time, BT will not download all the parts of the file from the server completely, but selectively download the downloaded parts from other users' machines according to the actual situation. For example, if Party A downloads 1 and Party B downloads 2 parts, then Party C will download 1 from Party A's machine and 2 parts from Party B's machine. Of course, Party A, Party B and Party D also download the corresponding parts from Party C's machine at the same time, which greatly reduces the load on the BT server and accelerates the download speed of Party C. That is to say, every computer involved in the download will download from both parties.
At present, there are too many popular BT software, BitTorrent, the originator of BT, bitspirit called BitSpirit, greedy BT, and shareaza, the generalist .............................................................................................................................. In the face of numerous BT software, how should we choose? The following content will help you find the answer!
Tips: Do you know the difference between BT download and ordinary download? Unlike ordinary download files, when you download BT, the addresses you start to link to are all files that end. Rapids. In fact, as long as you download this file, you can download BT by running this file on this machine. BT download links on the Internet are all published and provided by users themselves, which makes the download materials very extensive and not restricted by conventional managers.
The soul of BT download: seeds. No matter what kind of BT client program, the default settings do not limit the download speed and upload speed. This is because BT software will give priority to users who upload faster, which means that the faster the upload speed, the faster the download speed, so if you use broadband, don't limit the upload speed when downloading.
After the download, if you don't close the BT client program (for example, you will browse the web and edit documents while running the upload service provided by BT). ), then you will become the messenger of the torch relay, that is, the "seed". In other words, if a file is divided into 10 parts, but only one person owns the ninth part, that is, there is only one seed, if this user is disconnected or turned off for some reason, then other users can only download to 90%, which is the most annoying thing when downloading BT.
Think about the pain of "zero seeds" when downloading. Take care of yourself. Try not to close the BT program window immediately after downloading, and be a torch relay messenger.
Why BT download speed is not fast?
Sometimes BT download speed is not fast, there are many reasons. For example:
1. is not a public network user. Because intranet users can't provide active connection, the download speed will definitely be slower than that of public users, which is normal.
2. The upload speed is limited. Since all BT client programs provide priority services for users with fast upload speed, if you limit the upload speed, you actually limit your download speed in disguise.
3. The number of seeds is too small. If the number of seeds is too small, it will certainly affect the download speed of other users. There is no way. This still requires every BT user to carry forward the spirit of "Lei Feng". Never shut down BT immediately after downloading, otherwise the number of seeds will be less and less.
4. Firewall blocking. Firewall software will also have a certain impact on the download speed of BT. Of course, in order to ensure the security of the system, this small impact can still be ignored.
Influence of BT download on hard disk life
After the popularization of BT download, there have also been cases that will cause great damage to the hard disk. In fact, the BT download method should be changed. Did you learn it from me? Hey? Most users who download T-shirts use broadband, so naturally they will not consider the Internet access fee. They may leave their computers on all day and all night to download, and BT users usually provide uploading services at the same time. If a file is downloaded by 10 people at the same time, your hard disk will bear 1 downloads and 9 uploads (10- 1). If 100 people download at the same time, the hard disk will take a long time, and it is easy to cause a "fever" of the hard disk due to continuous work, which is why it is rumored that using BT download will lead to the damage of the hard disk.
When downloading BT, the data with corresponding capacity will be written into the hard disk buffer to generate a file with the same size as the downloaded file, and then the corresponding part of the file will be downloaded randomly to fill the file. When all the files are filled, the download is over.
So if you often use BT to download files, you must set the capacity of hard disk cache files larger. In addition, the task manager can be used to appropriately reduce the priority of BT software, so that even if a certain amount of resources are occupied, it will not have much impact on other applications; It is absolutely forbidden to turn off the computer abnormally before the file download is completed, otherwise it may have a certain impact on the life of the hard disk.
