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 ...

In compilers, backward compatibility may refer to the ability of a compiler for a newer version of the language to accept source code of programs or data that worked under the previous version. [8] A data format is said to be backward compatible when a newer version of the program can open it without errors just like its predecessor.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 cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet .
Convolutional codes are processed on a bit-by-bit basis. They are particularly suitable for implementation in hardware, and the Viterbi decoder allows optimal decoding. Block codes are processed on a block-by-block basis. Early examples of block codes are repetition codes, Hamming codes and multidimensional parity-check codes.
For backward compatibility, the 3270 PC translated these to XT (set 1) scancodes using an add-on card and a BIOS extension. This set is used by Linux by default when it detects a PS/2 keyboard that can properly support scan code set 3. [2] The IBM PC AT introduced the "AT" ("set 2") scancodes.
