Multics

Multics (Multiplexed Information and Computing Service) was an influential early computer operating system developed in the 1960s to manage large-scale, multi-user access to powerful mainframe computers. It introduced advanced features like security protections, dynamic resource management, and modular design, laying the groundwork for modern operating systems. Multics allowed multiple users to run programs simultaneously, ensured data security, and provided a flexible, reliable environment. Its innovations influenced later systems like Unix, shaping today's computing architecture by demonstrating key principles of multitasking, security, and scalability.
