The source code, in C, will depend on what type of lossless compression algorithm will be used. A source code should be available from various computer scientists in your area.

What is compressed data file?
A compressed data file is a file where the data has been re-encoded in such a way as to reduce the overall length of the file (in bytes). Data compression is useful as it allows us to fit more data into a given space, which is useful for backup purposes (hence compression programs are also known as archive programs). Compression also allows us to transmit data across a network more efficiently. In addition, we can re-encode multiple files into a single compressed file known as a volume. Large volumes can also be split into a series of smaller volumes. This is useful when a single volume is too large to fit onto a DVD, for instance. Compression programs can also be integrated into the operating system shell program such that we can treat compressed volumes as easily as we can folders, allowing compression and decompression "on-the-fly". There are two ways to compress data: with loss and without loss. Lossless compression means we can faithfully restore the original data from the re-encoded data. All data archiving programs use lossless compression. Lossy compression means the lost data can never be recovered unless we have a backup of the original source data. Audio and video data can both make use of lossy compression (up to a point) because the human eye and ear are quite forgiving; we can remove massive amounts of redundant data before we begin to notice any difference. For instance, MP3 audio compression can reduce a 50 MB CD-quality audio file to around 5 MB without any appreciable loss in fidelity. The audiophile and "golden ear" community will always claim MP3 is inferior to CD (which it technically is), but extensive blind-testing under laboratory conditions has shown that they can't tell the difference. Lossy compression can also benefit from lossless compression to a degree. Once the redundant data has been removed, a lossless compression algorithm can be applied to the remaining data. In the case of MP3, Huffman prefix encoding can be applied to each encoded audio frame. Run Length Encoding, Huffman prefix encoding and arithmetic encoding are common examples of lossless encoding techniques. The more efficient lossless algorithms, such as LZW, are patented and require a licence to use in your own programs, however there are open source algorithms available, including the popular 7-Zip, although some restrictions still apply.

How do i get source code for bide algoritham?
You can get the Java source code for the BIDE data mining algorithm here : (link moved to link section) It is an open-source data mining framework that includes the BIDE algorithm
Why the source coding of every compression utility software is in Visual C plus plus and why not in java?
Compression/decompression is all about raw speed and efficiency. Java is neither fast nor efficient. However, converting from C++ to Java isn't terribly difficult and Huffman's algorithm and its variations are well documented. Just don't expect to create anything that's remotely useful to you in Java.
Java source code for median filter algorithm?
research is going on to develop a source code for median filtering using java
What does a compression wave moving outward from its source produce?
Sound wave
What are magnetic cars?
Magnetic air cars uses air compression as the source for propusion. It is "magnetic" in the sense that a magnetic motor is used for the air compression.
What is a lossless transmission line?
A lossless transmission line is when no energy is lost during transmission of energy from a particular source to destination by a certain material, ie. copper wire. In other words, this material that transmits energy, absorbs none of the energy transmitted. No energy is lost to the material during transfer of energy. It is like saying it is an absolutely perfect conductor having no resistance.
Is AAC lossy or lossless?
yay!! i got a blog!...... But i think Ipods are better because they may not have as much memory as the average Mp3, but the sound is louder and it just looks more..um..STYLISH i guess really! - Mark .j. Townend
Is it most encryption programs compress files?
No. Encryption is not compression. Compression occurs before (and possibly again after) encryption when outgoing, and reversed when incoming. In all probability, the encrypted file is likely to be a few byes larger than the original source data, but since compression is applied first, the overall transmission is likely to be smaller than the source.
Does a tractor pull things?
Yes. Tractors are a source of power that pulls implements behind it that till the ground, spray herbicide, harvest crops, etc.
What is the java code for Bellman Ford algorithm?
The Bellman-Ford algorithm computes single-source shortest paths in a weighted digraph.For graphs with only non-negative edge weights, the faster Dijkstra's algorithm also solves the problem. Thus, Bellman-Ford is used primarily for graphs with negative edge weights. The algorithm is named after its developers, Richard Bellman and Lester Ford, Jr.
