Study Notes
Operating System Overview
- An operating system (OS) acts as a manager of computer hardware resources and provides a platform for running application software.
Role of an Operating System
- A OS plays a crucial role in managing computer hardware resources and providing a platform for running application software.
Definition of an Operating System
- A OS is a software that manages computer hardware resources and provides common services to computer programs.
Types of Operating Systems
- A handheld computer OS is designed to provide an environment for executing programs on handheld computers.
Design Priorities of Operating Systems
- Some OS are designed to be convenient, while others are designed to be efficient.
Early Computer Systems
- Early computer systems were designed to perform specific tasks and were not designed to be general-purpose computers.
Modern Time-Sharing Systems
- In modern time-sharing systems, the unit of work is typically a process or a job.
Process Management
- There are two types of processes in a system: I/O-bound and CPU-bound processes.
Batch System vs Time-Shared System
- The main difference between a batch system and a time-shared system is the way the CPU is allocated to jobs or processes.
Process Switching
- The purpose of switching the CPU between processes in an operating system is to improve system performance and throughput.
