Study Notes
Operating Systems Overview
- An operating system (OS) efficiently manages computer resources and resolves conflicting requests to optimize usage.
- Application programs handle basic computing resources including CPU, memory, and I/O devices.
System Initialization and Configuration
- The bootstrap program, stored in RAM, initializes key components of the computer system upon startup.
Embedded and Shared Computer Systems
- Embedded systems, found in devices and automobiles, typically lack a user interface.
- Shared computers, such as mainframes, focus on resource utilization rather than user convenience.
Core Functions of Operating Systems
- An OS is responsible for the organization of computer systems, operating primarily through:
- Process management
- Memory management
- Storage management
Misconceptions in Operating Systems
- Operating systems do not involve themselves with the protection and security of the computer system.
- Kernel data structures are deemed unimportant in the operational functionality of an OS.
- Contrary to belief, not all operating systems are closed-source; there are open-source alternatives available.
