Resident monitors, also known as operating systems, brought several improvements to computer operations. Some of the key improvements include:

• Efficient resource management: Resident monitors allowed for efficient management of hardware resources such as memory, CPU, and input/output devices. They provided mechanisms for allocating and sharing resources among multiple processes, optimizing their utilization.
• Time-sharing and multitasking: Resident monitors introduced the concept of time-sharing and multitasking, enabling multiple users or processes to run concurrently on a single computer system. This significantly increased system throughput, allowing multiple tasks to be executed simultaneously.
• Improved user interface: Resident monitors provided a more user-friendly interface compared to earlier systems. They introduced concepts like command-line interfaces and later graphical user interfaces (GUIs), making it easier for users to interact with the computer.
• File management: Resident monitors introduced file systems, allowing users to organize and store information in a hierarchical structure. This enabled efficient storage, retrieval, and management of data, leading to improved data organization and access.
• Program execution and software development: Resident monitors provided mechanisms for loading, executing, and terminating programs. They also introduced debugging and error handling capabilities, making software development and troubleshooting easier and more efficient.
• Device driver support: Resident monitors introduced device drivers, which acted as intermediaries between the operating system and hardware devices. This allowed for standardized and efficient communication with various hardware components, simplifying device management.

Overall, resident monitors brought about significant improvements in resource management, multitasking, user interface, program execution, and device support, making computer operations more efficient and user-friendly.
