Information:  - U2 are an Irish rock band from Dublin formed in 1976. The group consists of Bono (lead vocals and guitar), the Edge (guitar, keyboards, and backing vocals), Adam Clayton (bass guitar), and Larry Mullen Jr. (drums and percussion). Initially rooted in post-punk, U2's sound grew to incorporate influences from many genres of popular music, yet has maintained an anthemic sound. Their lyrics, often embellished with spiritual imagery, focus on personal themes and sociopolitical concerns.  - Information theory studies the quantification, storage, and communication of information. It was originally proposed by Claude E. Shannon in 1948 to find fundamental limits on signal processing and communication operations such as data compression, in a landmark paper entitled "A Mathematical Theory of Communication". Now this theory has found applications in many other areas, including statistical inference, natural language processing, cryptography, neurobiology, the evolution and function of molecular codes, model selection in ecology, thermal physics, quantum computing, linguistics, plagiarism detection, pattern recognition, and anomaly detection.  - Debt, AIDS, Trade, Africa (DATA) was a multinational non-government organization founded in January 2002 in London by U2's Bono along with Bobby Shriver and activists from the Jubilee 2000 Drop the Debt campaign.  - Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers. It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems.  - Paul David Hewson (born 10 May 1960), known by his stage name Bono, is an Irish singer-songwriter, musician, venture capitalist, businessman, and philanthropist. He is best known as the lead vocalist of rock band U2. Bono was born and raised in Dublin, Ireland, and attended Mount Temple Comprehensive School where he met his future wife, Alison Stewart, and the future members of U2. Bono writes almost all U2 lyrics, frequently using religious, social, and political themes. During U2's early years, his lyrics contributed to their rebellious and spiritual tone. As the band matured, his lyrics became inspired more by personal experiences shared with the other members.  - Jubilee 2000 was an international coalition movement in over 40 countries that called for cancellation of third world debt by the year 2000. This movement coincided with the Great Jubilee, the celebration of the year 2000 in the Catholic Church. From early 2001, Jubilee 2000 split into an array of organisations around the world.  - In computer science and information theory, data differencing or differential compression is producing a technical description of the difference between two sets of data  a source and a target. Formally, a data differencing algorithm takes as input source data and target data, and produces difference data such that given the source data and the difference data, one can reconstruct the target data ("patching" the source with the difference to produce the target).  - Delta encoding is a way of storing or transmitting data in the form of differences ( deltas ) between sequential data rather than complete files ; more generally this is known as data differencing . Delta encoding is sometimes called delta compression , particularly where archival histories of changes are required ( e.g. , in revision control software ) . The differences are recorded in discrete files called `` deltas '' or `` diffs '' . In situations where differences are small -- for example , the change of a few words in a large document or the change of a few records in a large table -- delta encoding greatly reduces data redundancy . Collections of unique deltas are substantially more space - efficient than their non-encoded equivalents . From a logical point of view the difference between two data values is the information required to obtain one value from the other -- see relative entropy . The difference between identical values ( under some equivalence ) is often called 0 or the neutral element .    'delta encoding' is related to which object entity through the relation of 'use'?
