Study Notes
Device Management
- Managing diverse devices connected to a system presents challenges.
File Management
- The File Manager is responsible for tracking all files on the system, including data, program files, utilities, compilers and applications.
- It enforces access policies set by system designers.
- It allows authorized individuals to modify permissions and restrictions on files.
Example of Access Control
- A user may have read-only access to a sensitive database.
- A system administrator may have read-and-write access and the authority to manage files within the same database.
File Allocation
- The File Manager manages space on secondary storage devices to ensure efficient data retrieval.
- It needs to understand the technical requirements of the device storing the file.
Network Management
- Operating systems with networking capabilities include a Network Manager for:
- Overall network connectivity.
- Management of resources like memory space, CPU capacity, transmission connections, and encryption types.
Network Types
- Networks can range from small wireless systems to extensive private networks.
User Interface
- The user interface is crucial for interaction with the operating system.
Types of Interfaces
-
Graphical User Interface (GUI)
- Relies on input from pointing devices (e.g., mouse or finger).
- Offers specific menu options and formats.
-
Command Line Interface
- Responds to specific commands typed on a keyboard.
- Requires accurate command input with correct syntax.
Command Structure
- Commands can be combined to execute complex tasks.
- Requires precise assembly to prevent errors.
User Considerations
- Users need to understand how to recover from errors encountered during command execution.
