TSO (Time Sharing Option)

TSO (Time Sharing Option) is a command-line interface in IBM mainframe systems that allows multiple users to interact with the computer simultaneously. It provides a way to run programs, manage data, and perform tasks through text-based commands, enabling efficient resource sharing. Users can access system functions in real-time, making TSO essential for managing and operating large-scale enterprise computing environments. It acts as a window for users to communicate directly with the mainframe's operating system, supporting multitasking and streamlined workflow management.
