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.
