Study Notes

Performance Factors

Speed: Essential for efficient computing; affects response times and overall system performance.
Cost: Important consideration when selecting technology platforms and systems.
Volatility: Refers to the stability and reliability of data storage solutions.

Caching

Data copied into faster storage systems (e.g., main memory).
Main memory can be viewed as a final cache for secondary storage.

Operating System Structure

Multiprogramming: Enhances efficiency by allowing multiple processes to run simultaneously.
Timesharing (Multitasking): CPU frequently switches jobs, enabling user interaction with multiple running processes.

Process Management Activities

Creation and deletion of user and system processes.
Suspending and resuming processes to manage workload.
Provides mechanisms for process synchronization, communication, and deadlock handling.

Memory Management

Manages data and instructions in memory for execution.
Determines what data resides in memory during processing.

Storage Management

Offers a uniform, logical view of information storage.
Manages file systems to organize and access data efficiently.

Protection and Security

Protection: Mechanisms controlling access to resources by processes or users.
Security: Defends the system against internal and external attacks; differentiates user permissions.

Common OS Commands

dir command: Lists all files in a directory or drive.
cd command: Changes the current working directory to a designated one.
cd .. command: Navigates back to the previously opened directory.
Tree command: Displays files and folders in a tree format for better visualization.

Game Platforms

Environments optimized for gaming, featuring services such as 3D engines and AR/VR APIs.

Platform Technology

Environments designed for building and operating applications, systems, and processes.

Operating System Overview

Acts as an intermediary between the user and computer hardware.
Goals include executing user programs and enhancing convenience of use.

Computer System Structure

Comprises four key components: Hardware, Operating System, Application Programs, and Users.

Operating System Definition

Functions as a resource allocator and control program.
No universally accepted definition; often described as the kernel or the foundational program running continuously.

Computer Startup Process

A bootstrap program is loaded during power-up or reboot to initiate the system.

Computer-System Operation

Input/Output devices operate concurrently with the CPU, utilizing device controllers for improved efficiency.
Local buffers store data temporarily during processing.

Storage Structure

Different types of storage: Main memory, secondary storage, and magnetic disks.
Organized in a hierarchical structure for efficient data management.

Common Types of Technology Platforms

Include Operating Systems, Computing Platforms, Database Platforms, Storage Platforms, Mobile Platforms, Web Platforms, APIs, and more.
Serve as foundational services that enable specific functionalities across software applications.

Cloud Computing and Databases

Database platforms are designed for managing relational, NoSQL, and in-memory databases.
Enables scalability and flexibility in data storage and management solutions.
