Study Notes

Operating System Fundamentals

Speed, cost, and volatility are critical factors in operating systems.
Caching involves copying data to a faster storage medium; main memory serves as a last cache for secondary storage.

Operating System Structure

Multiprogramming enhances efficiency by allowing multiple processes to run concurrently.
Timesharing (multitasking) enables users to interact with multiple jobs simultaneously via rapid CPU switching.

Process Management Activities

Operating systems manage processes by:
- Creating and deleting user and system processes.
- Suspending and resuming processes as needed.
- Synchronizing processes to ensure proper execution order.
- Facilitating process communication.
- Handling deadlocks that may arise.

Memory Management

Memory management is crucial for managing data and instructions necessary for execution.
It determines what data resides in memory during processing.

Storage Management

Operating systems create a standard view of information storage.
File-system management is a key aspect of storage management.

Protection and Security

Protection mechanisms control access to resources defined by the operating system.
Security measures defend against internal and external threats, requiring user distinction to manage permissions.

Command Line Operations

dir command lists all files in a directory.
cd command changes the current directory; cd.. navigates back to the previous directory.
tree [path] displays files and folders hierarchically, illustrating directory structure.

Game Platforms

Game platforms include optimized environments for gaming, utilizing 3D engines and AR/VR APIs.

Technology Platform

A technology platform provides environments for application development and operations.
Platforms offer toolsets for services that are customizable and tailored.

Operating System Definition

An operating system acts as an intermediary between users and hardware.
Goals include executing user programs and enhancing usability.

Computer System Structure

A computer system encompasses four components: hardware, operating system, application programs, and users.

Computer Startup Procedure

The bootstrap program initializes the system upon power-up or reboot.

Computer System Operation

I/O devices and CPU can operate concurrently using device controllers.
Each controller is responsible for a specific device type, utilizing local buffers for data transfer.

Storage Structure

Two main types of storage are present: main memory and secondary storage (e.g., magnetic disks).

Storage Hierarchy

Storage systems are organized hierarchically for efficient access and management.

Common Types of Technology Platforms

Types include:
- Operating Systems
- Computing Platforms
- Database Platforms
- Storage Platforms
- Application Platforms
- Mobile Platforms
- Web Platforms
- Content Management Systems
- Media Platforms
- API Platforms
- Analytics
- Security
- Robotics
- Internet of Things
- AI Platforms
- Game Platforms

Computing Platforms

Built on operating systems, facilitating cloud computing and virtualized services.
Allow dynamic scaling by adding or removing virtual machines.

Database Platforms

Provide environments for managing databases, including relational and NoSQL types.

Storage Platforms

Offer scalable storage solutions along with APIs for enhanced services like resilient storage.

Application Platforms

Environments and toolkits focused on developing and deploying applications for user interaction.

Mobile Platforms

Include mobile operating systems and environments suitable for mobile app development.
