BT Download: Novice Literacy +BT Ultimate Acceleration Method

There is a lot of knowledge about BT download in the forum, which may be scattered. No one wants to finish reading such a long post. I rambled and wrote some words suitable for BT novices to share with you. Experts, don't laugh at me.

1, why BT?

BitTorrent is BT for short. Unlike our usual FTP and HTTP downloads, many people get stuck in traffic. BT is distributed download, as the BT proverb says: the more people download, the faster the speed. It is a very good choice for netizens to exchange large files. But it is not suitable for small files, because everyone will leave after reading it. Less people will slow down. If there is no seed (100%, as long as it is not sealed, it will be a seed), everyone will be stuck in the point with the highest degree of completion. It doesn't matter if the download is interrupted halfway. It supports breakpoint continuation.

2. Commonly used BT software

There are many BT softwares, and the following two are commonly used:

BitTorrent S-5.8.D Chinese version (I use this), download address: there are endless movies and software.

A. to use BT download, you must first find. Torrent files on the internet, generally you will automatically start your BT download software;

B. This file is very small (generally 20k- 100k) and will be downloaded soon. Then a dialog box will pop up asking about the storage location of files/folders (BT can publish the whole directory);

C. BT then starts to allocate space (generate an empty file with the same size as the target file), which takes 1 to 2 minutes, depending on the size of the downloaded file.

D. After the space is allocated, the file will be downloaded by itself. The initial download will be slow, and the speed is also related to your own network. If it's a dial-up or community intranet, it will be pitifully slow, but it doesn't matter. Hang up and go to sleep by yourself.

E. It doesn't matter if the download is interrupted in the middle, and breakpoint continuation is supported. Click the download link again on the forum/release page, or open the log of your BT software, and the selected file can continue.

F After the download is completed, please note: Do not close this window immediately at this time, because you can provide downloads for others at this time. Please remember the motto of BT: The more people download, the faster the speed will be.

G. for beginners, it is necessary to remind everyone that when downloading, look at the release date first. Generally, those released half a month ago are hopeless If you can't connect with other downloaders after more than 20 minutes, you don't need to try again.

Q: I often hear the word BT download. Can you explain its meaning in detail?

A: BT download is an open source P2P software, which adopts the multipoint-to-multipoint transmission principle and is suitable for downloading large files such as movies. Using BT to download is different from using traditional HTTP sites or FTP sites. With the increase of download users, the download speed will be faster. Based on this feature

Download the latest movies, software, etc. with BT. There is a great advantage in speed. The use of BT download software is very simple. On the premise that the software has been installed, you only need to find the seed file (*. Torrent), then click on it and follow the steps prompted by the system to start downloading.

BT actually refers to a novel download method, which belongs to the category of P2P software in essence. Many friends regard BT as a revolutionary download.

However, some ISP vendors regard it as a scourge. Why?

For HTTP, FTP, PUB and other download methods, files are usually put on the server first, and then transmitted to each user's machine by the server. Obviously, if too many users download at the same time, the download speed of all users will be affected. If some users use multi-thread download, the impact on bandwidth will be more serious and the server may crash. So almost all download servers are limited by the number of users and the maximum download speed.

Obviously, due to the above reasons, it is usually difficult to reach the highest download speed promised by operators even if broadband networks are used. There are network reasons, but it is also related to the limitations of the server. Because of this, BT download mode has quickly become the favorite of download lovers after its appearance, and many users use BT software to communicate the latest movie blockbusters or software.

Comparison of common BT software

Below, the author compares the commonly used BT software in China from the aspects of installation and use, operation interface, custom settings and special functions. I hope my friends can choose a satisfactory software, which can not only enjoy the pleasure of extremely fast download, but also won't cause too much damage to the hard disk.

1. bit stream

This is the official client program of BT, and all other BT software is developed based on it. BitTorrent supports breakpoint continuation. Unfortunately, the information provided in the download window is too simple. As shown in the figure, the default setting here is "unlimited". Of course, you can also choose other modes, such as "super seed" to be a super seed.

2.BitTorrent Plus？ two

BitTorrent Plus！ It is an enhanced version of the experimental version of BitTorrent Shadow, and it has an all-Chinese interface. After the installation is completed, the setting interface will automatically open. You can customize the port range, set the maximum upload speed or upload connection, click the "Advanced Settings" button, and set the local IP address, proxy server, default "seeding" mode and other options. If you enable the Psyco module, you can reduce the use of CPU and improve the running speed of the program. This option is recommended for users with more than 256MB of memory. Enabling safe mode can prevent some malicious downloaders from opening multiple clients in order to gain more download rights. This feature can reject multiple connections from the same IP address.

We can set the password under the "Tools" menu, so when restoring the window from the taskbar, we must enter the password, which increases the security. In addition, it also provides the function of making "seed" files, which can be selected from the "Tools" menu. It can be said that it is one of the most powerful client programs of BT.

3. greedy BT

Greedy BT, also called "Greedy BT", is actually just a China version of ABC, which uses Bittorrent Experimental of Shad0w as its kernel. Of course, the original version is BitTorrent, which has unparalleled advantages in speed and function.

As shown in, the default setting can download two tasks at the same time. If you are using Windows 98/Me, it is recommended that the number of tasks running at the same time should not exceed two. As for Windows 2000/XP, it can be increased to 3 ~ 6. If the machine configuration is high, the number of tasks can be increased appropriately. It seems that the name "greed" comes from this.

Greedy BT provides production and publishing functions. When making and selecting the number of blocks, you can choose the "automatic" automatic mode and remote control service. The command permissions that can be set are query, delete and add, but the default setting is to turn off the remote control service when starting the program, which is also for security reasons.

4. Bit spirit

BitSpirit's English name is Bitspirit, which takes up very little memory. It is very similar to FlashGet in appearance and interface. It has the function of defining download category and task management from bottom to top. Because it provides intelligent and controllable caching service, it can minimize the number of hard disk accesses.

It is worth noting that BitSpirit also has a very warm function, that is, it can be set to automatically shut down after downloading, and you can select "Automatically shut down after all tasks are completed" in the tab of "Options → Personal Settings → Others".

In addition, if the full installation mode is selected, two components, BSCC and TorrentBuilder, will be installed at the same time. BSCC from LANSPIRIT.COM is equivalent to an instant messaging software. As long as you enter your favorite nickname and set the server address and port number, you can communicate with other downloaders. TorrentBuilder can guide users to make and publish quickly "? . Torrent file, you just need to select the uploaded file or folder, and then click the "Make" button.

5. Super BT Download Software

In fact, Super BT download software is the China version of Shareaza. It is a highly appraised and popular P2P software abroad, which integrates five popular P2P downloading methods, such as Magnet, Piolet, Gnutella, BitTorrent and eDonkey 2000. It can be downloaded by HTTP and is also a completely free software.

Just drag the *. Torrent "file into the main window of Shareaza, and then click the" Download Now "button. Shareaza will automatically find available download resources from the BT server, and will automatically start downloading files after the connection is successful. What is more distinctive is that Shareaza provides a quite good media player, and you can use it to play media files in CDA, WAV, DIVX and other formats.

Step 6 break out

The special feature of this software is that it displays the corresponding download information in the command line window. Although it looks a little different, it is appropriate to relax your eyes once in a while if you are used to seeing black words on a white background in Windows standard programs. Of course, you can continue to switch to the "Monitor" tab of the main window to view the download information.

Tip: All BT software is free and can only be used after installation, and it is also convenient to uninstall. Except BitTorrent and Super BT Download Software (Shareaza), other softwares can make and publish "seed" files. Almost all software supports drag-and-drop operation, controlling download or upload speed and controlling the maximum number of connections, so I think choosing any BT software should meet your needs. In addition, although Shareaza provides media playback function, I believe that not many friends will take a fancy to this. What I appreciate more is bitspirit's automatic shutdown function after downloading.

Crisis of BT software

On the surface, BT software is booming and enthusiastic at present, but there are also many crises lurking, as follows:

1. Hard disk is damaged.

Many friends think that BT download will damage the hard disk. In fact, this is because before BT download, a mirror file with the same capacity as the downloaded file will be written in the hard disk buffer, and then the data will be written by filling. When the filling process is over, the downloading process is completed. Every time you download, the software also needs to check and calculate all the blocks, which consumes a lot of resources and wears the hard disk. If you read and write at the same time during downloading and uploading, the hard disk may have bad tracks.

Understand this principle, we can appropriately increase the size of the hard disk cache file, in addition, we should pay attention to avoid other reading and writing operations on the hard disk when using BT software, and on the other hand, we should avoid overloading the hard disk, which will generally not cause great damage to the hard disk.

2. Seriously occupy bandwidth

Because the working principle of BT is "multipoint download", that is to say, the more users participate, the faster the download speed of a single user will be. However, in practice, many users generally limit the upload speed in order to avoid excessive occupation of system resources and for security reasons, and sometimes even close BitTorrent immediately after downloading, so that the number of available "seeds" will become less and less. This affects the download speed of other users, and sometimes even the number of "seeds" is zero, which is also the reason why users complain about the slow download speed of BT.

3. Network security

Fundamentally speaking, BT software still belongs to background operation. Whether downloading or uploading files, there are hidden dangers such as illegal intrusion and privacy disclosure. Moreover, opening the port may also lead to the invasion of hackers or Trojan horses, so it is essential to install anti-virus software and firewall software in the system.

However, the author still believes that even if BT software has the above-mentioned crises and its fate has been in an uncertain situation, it is a brand-new way of network enjoyment in the broadband era, "everyone is for me, and I am for everyone", and I believe that BT will have a better tomorrow.
