Study Notes
Overview of Operating Systems
- An Operating System (OS) is software that manages hardware and software resources of a computer.
- It facilitates interaction between users and computer hardware.
- Essential functions include processor management, memory management, and error detection.
Key Concepts in Operating Systems
- Topics covered range from basic to advanced concepts such as:
- System Structure
- CPU Scheduling
- Process Synchronization
- Deadlock Management
- Processes and Threads
- Memory Management
- Disk Management
System Structure
- Involves the organization of various components of an OS and how they interact.
CPU Scheduling
- Manages the execution order of processes to optimize CPU usage.
Process Synchronization
- Ensures that multiple processes operate concurrently without conflict.
Deadlock
- A situation where two or more processes are unable to proceed because they are each waiting for the other to release resources.
Processes & Threads
- Processes are instances of programs in execution, while threads are smaller units within a process.
Memory Management
- Handles allocation and deallocation of memory space to processes as needed.
Disk Management
- Involves managing data storage and retrieval from disk devices.
Types of Operating Systems
- There are various types of operating systems including:
- Batch Operating Systems
- Time-Sharing Operating Systems
- Distributed Operating Systems
- Real-Time Operating Systems
Functions of Operating Systems
- Functions include managing hardware, executing applications, providing user interfaces, and handling system security.
FAQs on Operating Systems
