Process Management in operating systems is akin to a project manager's role, coordinating and controlling computer processes. It involves managing process life cycles, from creation to termination, and includes strategies like Monoprogramming, Multiprogramming, and Time-sharing. The text delves into the benefits and drawbacks of different management strategies and examines real-world examples from Windows, Linux, and macOS. Emerging trends in Process Management are also discussed, highlighting future directions in technology.
