The Evolution of Unix: A Story of Collaboration and Innovation Unix Concepts And Applications By Sumitabha Das Pdf Github
In the late 1960s, the world of computing was dominated by mainframe computers, which were large, expensive, and proprietary. The idea of a multi-user, multi-tasking operating system was still in its infancy. This was the era when the Unix operating system was born.
The story begins at Bell Labs, where computer scientists Ken Thompson and Dennis Ritchie were working on a project to develop a file system for the MULTICS operating system. However, they soon realized that the project was too ambitious and decided to create their own operating system, which they called Unix.
Unix was designed to be a simple, yet powerful operating system that could be used by multiple users simultaneously. It was written in a high-level language called C, which was also developed by Ritchie. The first version of Unix was released in 1971, and it quickly gained popularity among computer scientists and researchers.
