Operating System Fundamentals: Scheduling Algorithms and Deadlock Management
CPU Scheduling: Core Concepts and Algorithms
CPU scheduling is a critical component of Operating System design. It involves allocating the CPU’s processing time to different processes or threads, ensuring efficient use of system resources and improving system performance.
What is CPU Scheduling?
CPU scheduling determines which process should be executed next by the CPU, allocating CPU time to processes.
Key Goals of CPU Scheduling
- Maximize CPU Utilization: Keep the CPU busy as much as possible.
- Minimize
Operating System Concepts: Scheduling, Synchronization, and Deadlock Management
CPU Scheduling Fundamentals
CPU scheduling is the process of allocating the CPU (Central Processing Unit) to different processes or threads in a computer system. The primary goal of CPU scheduling is to maximize system performance, efficiency, and responsiveness.
Key CPU Scheduling Criteria
- Throughput: The number of processes completed per unit time.
- Turnaround Time: The total time taken for a process to complete, from submission to completion.
- Waiting Time: The time a process spends waiting in the ready
Real-Time Operating Systems: Core Concepts & Scheduling Algorithms
RTOS Fundamentals: Structure and Core Concepts
RTOS Structure and Characteristics
A Real-Time Operating System (RTOS) is an operating system designed to process tasks within strict timing constraints, ensuring predictable and deterministic execution. The structure of an RTOS includes key components such as the scheduler, task management, inter-task communication, memory management, and interrupt handling mechanisms. The characteristics of an RTOS include:
- Determinism: Guarantees task execution within
Collaborative Networks: Virtual Enterprises & Alliances
“A virtual enterprise is a temporary alliance of enterprises that come together to share skills or core competencies and resources in order to better respond to business opportunities, and whose cooperation is supported by computer networks.”
Participation in a collaborative network has the potential to bring significant benefits to the involved entities:
- “Survivability” in a context of market turbulence.
- Acquisition of a larger dimension.
- Access to new/wider markets and new knowledge.
- Sharing of

Oxy-Acetylene Welding: Techniques, Equipment & Safety
Welded Joints: An Introduction
Welded joints: These are created through a welding process, generally joining two pieces by using a heat source to achieve fusion. There are two main types:
- Homogeneous
- Heterogeneous
Oxy-Acetylene Torch Welding
Oxy-Acetylene Torch: This involves reaching the fusion temperature at the edges of the pieces being welded, or reaching the appropriate temperature to melt the filler rod when welding materials of different natures (heterogeneous welding).
