An operating system manages computer hardware resources and provides common services for programs. It performs key functions like process management, memory management, I/O device management, and a user interface. Operating systems have evolved from vacuum tube-based serial processing systems to today's personal computing systems. They have progressed from simple batch OSes to multi-programming OSes to time-sharing OSes. In conclusion, operating systems allocate resources, support applications and utilities, and control hardware while providing a user interface.

14. In conclusion, operating systems play several key roles:
Resource Management: Operating systems allocate and
manage computer resources such as CPU, memory, and
storage devices. Operating systems have evolved over time to
become more powerful and user-friendly. Today, there is a
wide range of operating systems available to choose from,
each with its own unique features and benefits.
