Operating systems provide a wide range of services to facilitate the operation and management of a computer system. Some of the key services provided by operating systems are:
Process management: Operating systems manage the execution of programs or processes and ensure that they run smoothly, efficiently, and without interfering with other processes.
Memory management: Operating systems manage the allocation and deallocation of memory to different programs and ensure that each program has enough memory to run properly.
File management: Operating systems manage the creation, deletion, and manipulation of files and directories on storage devices, such as hard drives and flash drives.
Device management: Operating systems manage the communication with various hardware devices, such as printers, scanners, keyboards, and mice.
Security: Operating systems provide security services such as user authentication, data encryption, and access control to protect data and resources from unauthorized access.
Networking: Operating systems provide networking services to allow communication between computers and to enable access to the internet.
User interface: Operating systems provide a user interface to allow users to interact with the system and execute commands or applications.
Error detection and handling: Operating systems monitor the system for errors and handle them appropriately to prevent crashes or data loss.
Backup and recovery: Operating systems provide backup and recovery services to help protect data from accidental deletion or system failure.
Virtualization: Operating systems provide virtualization services to allow multiple virtual machines to run on a single physical machine, allowing for greater utilization of hardware resources.
