What operating system functions are designed to ensure efficient operation of the system itself?
Resource allocation Accounting. Protection and security
Operating systems (OS) have a few functions that are specifically designed to ensure efficient operation of the system itself. These functions include:
1. Memory Management: The OS is responsible for managing the available memory resources to maximize efficiency. This involves allocating and deallocating memory to applications and processes, as well as implementing virtual memory when necessary.
2. Process Management: The OS is responsible for managing and coordinating the various processes running on a system. This involves scheduling tasks so that they are executed efficiently, determining which processes get priority over others, and managing resources such as processor time, memory usage, and input/output operations.
3. Device Management: The OS manages all hardware devices and their associated drivers. This includes configuring, initializing, and coordinating access to peripheral devices, such as printers, scanners, and network adapters.
4. File Management: The OS is responsible for managing files and directories on storage devices. It provides an interface for users and applications to create, modify, and delete files and directories, and also manages access control and file permissions.
5. Security Management: The OS implements various security measures to ensure the system is protected from unauthorized access or attack. This includes password protection, encryption and decryption of files and communication, and user authentication.
Overall, these functions are essential to ensure the efficient operation of the system itself, and to ensure that other applications and processes are able to run efficiently as well.
