Study Notes
Resource Management
- In computer systems, resources that need management include memory, processing power, and peripherals.
- Evaluating available resources varies by system type, such as servers, desktops, or mobile devices.
- Resource limitations can include insufficient memory, processing speed, or storage capacity, impacting overall system performance.
- Limitations can lead to issues like slow processing, application crashes, or inability to run multiple programs effectively.
Role of the Operating System
- The operating system manages memory allocation, device drivers for peripherals, and coordinates hardware functions.
- Resource management techniques include:
- Scheduling: Optimizes task execution order.
- Policies: Defines rules for resource access.
- Multitasking: Allows concurrent execution of multiple tasks.
- Virtual Memory: Expands physical memory using disk space.
- Paging: Divides memory into fixed-size units for easier management.
- Interrupt Handling: Manages asynchronous events.
- Polling: Regularly checks the status of devices.
- A dedicated operating system enhances performance for specific devices by optimizing resource use.
- Operating systems abstract hardware complexity, enabling users and applications to interact without needing detailed hardware knowledge.
Control Systems
- Control systems can be centralized or distributed, affecting efficiency and scalability.
- Microprocessors and sensor inputs are crucial in control systems, enabling data collection and processing.
- Various input devices (e.g., sensors, cameras) are evaluated based on data collection needs in specific scenarios.
- The relationship between sensor, processor, and output transducer is essential for feedback and control.
Feedback in Control Systems
- Feedback loops are fundamental for dynamic adjustments in control systems, ensuring goals are met and maintaining stability.
- Social and ethical impacts arise from embedded systems, focusing on privacy, security, and job implications.
Distributed Systems
- Centrally controlled systems differ from distributed systems in management efficiency, scalability, and fault tolerance.
- Autonomous agents play a crucial role in distributed systems, executing tasks independently within broader systems.
Object-Oriented Programming
- Recursion refers to functions that call themselves, useful for solving problems with a repetitive nature.
- Algorithms can utilize recursion effectively, demonstrating its application in problem-solving.
- Object references enable dynamic memory management, facilitating easier manipulation of complex data structures.
- Abstract Data Types (ADTs) such as lists are fundamental in programming, providing structured data management.
- Additional data structures include stacks, queues, and binary trees, each serving specific organizational purposes.
- Emphasis on naming conventions and code style is vital for code readability and maintenance.
- Library collections in programming, such as those in Java, optimize development efficiency and provide pre-built solutions.
