PL/I (Programming Language One) is a highly versatile programming language developed by IBM in the early 1960s to support its System/360 mainframe computers. Renowned for its ability to handle scientific, engineering, and business applications, PL/I combines features from different programming paradigms, making it a powerful tool for various computational needs.
Redundancy refers to the intentional or unintentional repetition of computer data or the engineering support of a system's weakness. This practice enhances reliability and safety in various systems by providing backup or fail-safes.
