Study Notes
Operating System Overview
- An operating system (OS) is essential software that oversees computer hardware and provides essential services for application programs.
- Operating systems represent a crucial part of system software in any computing environment.
Two Perspectives on Operating Systems
-
Resource-Manager View
- This perspective emphasizes the efficient management of computer system components.
- The OS allocates resources like CPU time, memory space, and I/O devices to various applications and processes.
-
Extended-Machine View
- This viewpoint highlights the OS's role in offering user-friendly abstractions that simplify the interaction with hardware.
- Key abstractions provided by the OS include:
- Processes: Represent running programs and their execution contexts.
- Address Spaces: Define memory allocation for applications, creating isolated environments for safe operation.
- Files: Structural units for storing data, managed by the OS to facilitate ease of access and organization.
