How Does a Download Accelerator Work?
Download Accelerator Basics
-
A download accelerator, is a piece of software that helps a computer download information more quickly over the Internet. A download accelerator is usually one component of a larger software program, known as a download manager. A download manager is a program that assists users with all aspects of downloading and uploading, adding useful options that are not always available through a web browser. Download Accelerator Plus is one of the most popular managers on the web, and boasts more than 100 million users worldwide.
Download Accelerator Functions
-
Download acceleration works in a way similar to downloading a .torrent file: the download manager splits the file to be downloaded into parts that are downloaded separately. The distinction is that a download accelerator assists with downloading a file from a single source, while torrent files and similar person-to-person downloading schemes involve downloading parts from many different sources. Certain cites place limits on bandwidth for single connection, so multiple connections achieve faster download rates. Also, by downloading in parts, a corrupted portion of data spoils only part of the download instead of all of it. So download acceleration doesn't necessarily speed up the user's connection itself, rather it optimizes the download so that it will more easily reach the users maximum connection speed.
Other Benefits
- While most download managers contain download accelerating tools, they can also provide other features to assist advanced Internet users. Some common features aside from download acceleration include: scheduling and queuing download tasks, repairing or resuming broken or failed downloads, and allocating bandwidth to different tasks. Many of the features download managers offer are intended for advanced internet users; the download accelerator portion is only reason many users choose to install a download manager.
How to Configure MSN Download Accelerator
Boost the performance of your MSN dial-up Internet speeds with the MSN
Dial-Up Accelerator software, made available for free to all MSN dial-up
customers. The software works by compressing data as it's routed
through your connection, making browsing and reading emails faster. The
software can be configured at various compression levels, depending on
how much you want to accelerate your internet speed

A download manager is a computer program dedicated to the task of
downloading (and sometimes uploading) possibly unrelated stand-alone
files from (and sometimes to) the Internet for storage. This is unlike a
World Wide Web browser, which is mainly intended to browse web pages,
composed of a multitude of smaller files, where error-free moving of
files for permanent storage is of secondary importance. (A failed or
incomplete web page file rarely ruins the page.) The typical download
manager at a minimum provides means to recover from errors without
losing the work already completed, and can optionally split the file to
be downloaded (or uploaded) into 2 or more segments, which are then
moved in parallel, potentially making the process faster within the
limits of the available bandwidth. (A few servers are known to block
moving files in parallel segments, on the principle that server capacity
should be shared equally by all users.) Multi-source is the name given
to files that are downloaded in parallel.

Adware
Download managers, such as Go!Zilla, were among the first adware
applications displaying a banner ad in the user interface. Adobe
Download Manager is now exhibiting this same feature, while installing
such software as Adobe Acrobat
Features
Download managers commonly include one or more of the following features:
Pausing the downloading of large files.
Resuming broken or paused downloads (especially for very large files).
Downloading files on poor connections.
Downloading several files from a site automatically according to simple rules (file types, updated files, etc. - see also Offline Browser).
Automatic recursive downloads (mirroring).
Scheduled downloads (including, automatic hang-up and shutdown).
Searching for mirror sites, and the handling of different connections to download the same file more quickly (segmented downloading).
Variable bandwidth usage.
Automatic subfolder generation.
Download managers are useful for very active Internet users. For dial-up users, they can automatically dial the Internet Service Provider at night, when rates or tariffs are usually much lower, download the specified files, and hang-up. They can record which links the user clicks on during the day, and queue these files for later download. For broadband users, download managers can help download very large files by resuming broken downloads, by limiting the bandwidth used, so that other internet activities are not affected (slowed) and the server is not overloaded, or by automatically navigating a site and downloading pre-specified content (photo galleries, MP3 collections, etc.) this can also include automatically downloading whole sites and regularly updating them (see Mirroring).
Many download managers support Metalink, an XML file listing mirrors, checksums, and other information useful for downloading.

"Download accelerator" redirects here. For the specific proprietary
program for Windows and Mac OS X, see Download Accelerator Plus.
Download acceleration, also known as multipart download, is a term for the method employed by software such as download managers to download a single file by splitting it in segments and using several simultaneous connections to download these segments from a single server.
The reason for doing so is to circumvent server side limitations of bandwidth per connection. Because in normal networking situations all individual connections are treated equally, rather than actual file transfers, multiple connections yields an advantage on saturated links over simple connections, both in terms of total bandwidth allocation and resilience. Many servers, however, implement a maximum number of simultaneous connections per client in order to mitigate this.
This is not to be confused with segmented downloading, which allows a client to download segments of a file simultaneously from multiple servers.
