Explanation. Downloading large amounts of data over the Internet for software updates can induce high network traffic problems, especially when a network of computers is involved. Binary Delta Compression technology allows a major reduction of download size by only transferring the difference between the old and the new files during the update ...
the L+1-bit binary representation of N+1, followed by; all but the leading bit (i.e. the last N bits) of X. An equivalent way to express the same process: Separate X into the highest power of 2 it contains (2 N) and the remaining N binary digits. Encode N+1 with Elias gamma coding. Append the remaining N binary digits to this representation of N+1.
In information theory, Shannon's source coding theorem (or noiseless coding theorem) establishes the statistical limits to possible data compression for data whose source is an independent identically-distributed random variable, and the operational meaning of the Shannon entropy . Named after Claude Shannon, the source coding theorem shows ...
In data compression, a universal code for integers is a prefix code that maps the positive integers onto binary codewords, with the additional property that whatever the true probability distribution on integers, as long as the distribution is monotonic (i.e., p ( i ) ≥ p ( i + 1) for all positive i ), the expected lengths of the codewords ...

Some web apps offer free PDF editing and annotation tools. The Free Software Foundation was "developing a free, high-quality and fully functional set of libraries and programs that implement the PDF file format and associated technologies to the ISO 32000 standard", as one of its high priority projects.
compress (software) compress is a Unix shell compression program based on the LZW compression algorithm. [ 1] Compared to gzip 's fastest setting, compress is slightly slower at compression, slightly faster at decompression, and has a significantly lower compression ratio. [ 2] 1.8 MiB of memory is used to compress the Hutter Prize data ...
Binary-coded decimal (BCD) is a binary encoded representation of integer values that uses a 4-bit nibble to encode decimal digits. Four binary bits can encode up to 16 distinct values; but, in BCD-encoded numbers, only ten values in each nibble are legal, and encode the decimal digits zero, through nine. The remaining six values are illegal and ...
