Study Notes
Operating System (OS) Function and Characteristics
- The primary function of the OS is to manage and provide controlled access to system resources, such as hardware, memory, and I/O devices.
System Resources and Access
- The OS provides controlled access to the system's hardware, memory, and I/O devices.
Excluded Services
- The OS typically does not provide services related to application-specific functions or business logic.
System Abstraction
- The OS masks the underlying hardware and system complexity from the programmer, providing a platform for them to develop applications.
Excluded Services Area
- The OS typically does not provide services related to business logic or application-specific functions.
Application Binary Interface (ABI)
- The ABI defines the interface between the application program and the operating system, including the binary format, memory layout, and system calls.
Interactive Operating System
- An interactive operating system allows the user to interact directly with the computer to request the execution of a job or perform a transaction, such as command-line interfaces or graphical user interfaces.
Early Computer Systems Problems
- A common problem in early computer systems from the late 1940s to the mid-1950s was the need for manual intervention and setup for each job or program, making it inefficient and prone to errors.
Operating System as a Control Mechanism
- What makes the OS as a control mechanism unusual is its ability to provide a layer of abstraction between the application software and the underlying hardware, managing system resources and providing a platform for application development.
Application Programming Interface (API)
- The key function of an API in a typical computer system is to provide a set of predefined functions and protocols that allow application software to interact with the operating system and access system resources.
