objective and function of the operating system
Yes, these are an operating system’s primary goals and functions:
Resource Management: Use CPU, RAM, storage, and I/O devices on computers as efficiently as possible.
Process management includes overseeing active processes, allocating work, and guaranteeing equitable access to system resources.
Memory management, which includes virtual memory management, is the control and allocation of memory space to processes.
File System Management: Provide methods for data storage and retrieval by organizing and managing files and directories.
Device Management: Take charge of and maintain peripherals such as disk drives, printers, and keyboards.
Security: Maintain data integrity and confidentiality, safeguard system resources, and enforce access control procedures.
User Interface: Make sure users can interact with the computer system in an easy-to-use manner.
Functions
Booting: Load and initialize the operating system during system startup
Process Management: Create, schedule, and terminate processes, and provide inter-process communication mechanisms.
Memory Management: Allocate and deallocate memory space, manage virtual memory, and implement memory protection.
File System Management: Create, delete, read, and write files, and manage file permissions and access control.
Device Management: Control and manage device operations, handle device interrupts, and provide device drivers.
Security: enforce authentication and authorization mechanisms, protect system resources from unauthorized access.
Networking: Provide networking support for communication between computers and devices.
Error Handling: Detect and handle system errors and exceptions to ensure system stability and reliability.
User Interface: Provide a graphical or command-line interface for users to interact with the system.
System Monitoring: Monitor system performance, resource usage, and system events for optimization and troubleshooting.
