The history of operating systems dates back to the early days of computing. The first operating systems were developed in the 1950s and were primarily used for batch processing. These early systems were simple and focused on managing the transition from one job to another. With the advent of time-sharing and multi-user systems in the 1960s, operating systems began to become more sophisticated, allowing multiple users to interact with the computer simultaneously.
Types of OS: Batch, Multi-programmed, Time-sharing, Distributed, and Real-time systems.
