Study Notes
I/O Device Management
- Hides hardware device peculiarities from the user
- Provides an abstract level of hardware devices
- Manages main memory for devices using cache, buffer, and spooling
- Maintains and provides custom drivers for each device
- Ensures proper use of devices to prevent errors
- Provides a convenient and efficient programming environment for users
File Management
- A file is a sequence of bits, bytes, lines, or records whose meaning is defined by its creator and user
- Files can be of any type, such as alphabetic, numeric, and alphanumeric
- File management involves creating, deleting, and manipulating files and directories
- Operating system responsibilities include file creation and deletion, directory creation and deletion, file mapping onto secondary storage, and file backup
Network Management
- Involves managing and administering a computer network
- Features include network administration, network maintenance, network operation, network provisioning, and network security
- Ensures efficient communication between different computers
- Includes fault analysis, maintaining quality of service, and performance management
Main Memory Management
- Aims to maximize memory utilization on the computer system
- Main memory is a volatile storage device that loses its contents in case of system failure or power loss
- It is a repository of quickly accessible data shared by the CPU and I/O devices
Secondary Storage Management
- Provides secondary storage to backup main memory due to its limited size
- Programs and data are stored on disk until loaded into memory
- Operating system responsibilities include free space management, storage allocation, and disk scheduling
Security Management
- Refers to controlling access to computer resources
- Mechanisms include controlling access to files, memory segments, CPU, and other resources
- Ensures that only authorized processes can operate on resources
- Operating system is responsible for enforcing control mechanisms
Learn about I/O Device Management in operating systems, which involves hiding hardware device details, managing main memory, preventing errors, and providing a convenient programming environment.
