Decompilation is the process of transforming executable code into a high-level, human-readable format using a decompiler.This process is commonly used for tasks that involve reverse-engineering the logic behind executable code, such as recovering lost or unavailable source code.
To decode a message, You apply the same substitution rules, but this time on the ROT13 encrypted text. (Any other character, for example numbers, symbols, punctuation or whitespace, are left unchanged.) Because there are 26 letters in the Latin alphabet and 26 = 2 × 13, the ROT13 function is its own inverse: [2]
In software development, obfuscation is the practice of creating source or machine code that is intentionally difficult for humans or computers to understand. Similar to obfuscation in natural language, code obfuscation may involve using unnecessarily roundabout ways to write statements.
The Tupolev Tu-4, a Soviet bomber built by reverse engineering captured Boeing B-29 Superfortresses. Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight ...
Backward chaining is implemented in logic programming by SLD resolution. Both rules are based on the modus ponens inference rule. It is one of the two most commonly used methods of reasoning with inference rules and logical implications – the other is forward chaining. Backward chaining systems usually employ a depth-first search strategy, e ...
In compilers, backward compatibility may refer to the ability of a compiler for a newer version of the language to accept source code of programs or data that worked under the previous version. [8] A data format is said to be backward compatible when a newer version of the program can open it without errors just like its predecessor. [9]
In coding theory, Hamming(7,4) is a linear error-correcting code that encodes four bits of data into seven bits by adding three parity bits. It is a member of a larger family of Hamming codes, but the term Hamming code often refers to this specific code that Richard W. Hamming introduced in 1950.
A Viterbi decoder uses the Viterbi algorithm for decoding a bitstream that has been encoded using a convolutional code or trellis code. There are other algorithms for decoding a convolutionally encoded stream (for example, the Fano algorithm ).
