Study Notes
Operating System Overview
- An operating system (OS) is system software that manages computer hardware and software resources.
- The primary goal of an OS is to provide a user interface and manage the execution of programs effectively.
Landmark Operating Systems
- The landmark operating system for batch systems generation is IBM's OS/360.
- This OS enabled automated job scheduling, significantly improving processing efficiency.
Multiprogramming and Shared Systems
- Multiprogramming allows multiple jobs to be active in memory simultaneously, maximizing CPU utilization.
- For shared computers, the primary goal of an OS is to efficiently manage resources among multiple users while maintaining system stability.
Mobile Device Operating Systems
- The primary goal of an OS for mobile devices is to optimize battery life, manage resource constraints, and ensure seamless app integration.
Embedded Computers
- An example of an embedded computer is a microcontroller in a washing machine, designed specifically for managing that appliance's functions.
Generational Advancements
- The generation of operating systems that enabled multiple jobs to be active at once is characterized by the introduction of multiprogramming techniques.
- Dedicated systems necessitate exclusive resource allocation for a single user, while shared systems distribute resources among numerous users.
Historic Operating Systems
- The first example of an operating system for batch systems was the Monitor Control Program (MCP), used on early computers to manage jobs.
Virtualization
- Virtualization in operating systems refers to creating virtual versions of physical resources, allowing multiple operating systems to run on a single hardware platform.
Open Source Operating Systems
- The main benefit of free/libre and open-source operating systems is the accessibility to source code, promoting collaboration and community-driven development.
Pre-Operating System Era
- Before operating systems, programs were run manually, requiring users to load each program individually without automated job management.
