Study Notes
Defining Operating System
- There are two views of an operating system: as a resource allocator and as a control program.
- The operating system manages all resources and decides between conflicting requests for efficient and fair resource use.
Operating System Functions
- An operating system is an interface between the user and hardware.
- It is responsible for executing programs, resource allocation, CPU management, file management, and other tasks.
- The purpose of an operating system is to provide an environment in which a user can execute programs in a convenient and efficient manner.
Operating System Goals
- Execute user programs and make solving user problems easier.
- Make the computer system convenient to use.
- Use the computer hardware in an efficient manner.
Operating System Components
- The kernel is the core part of an operating system, managing system resources and acting as a bridge between applications and hardware.
- System programs are associated with the operating system but are not necessarily part of the kernel.
- Application programs are not associated with the operating system.
Defining Operating System (Cont.)
- There is no universally accepted definition of what is part of the operating system.
- A simple viewpoint is that the operating system includes everything a vendor ships when you order the operating system.
- The features included in an operating system vary greatly across systems, from taking up less than a megabyte of space to requiring gigabytes of space and being based on graphical windowing systems.
- A more common definition is that the operating system is the kernel, which is the one program running at all times on the computer.
This quiz explores the two main views of an operating system: as a resource allocator and as a control program. It delves into how an operating system manages resources and controls program execution. No universally accepted definition of an OS is provided in the quiz text.
