Centralized, decentralized, distributed system을 비교하면?5 answersCentralized, decentralized, and distributed systems differ in their organizational structures and coordination mechanisms. A centralized system has a single coordinator controlling all activities, which can lead to system breakdowns if the coordinator fails. Decentralized systems involve equal participation of processes without a central coordinator, making program development more challenging but avoiding single points of failure. Distributed systems, like decentralized ones, lack a central coordinator but involve multiple cooperating processes communicating to achieve common goals. They offer fault tolerance and scalability, crucial for large-scale industrial processes. Resilience studies show that while centralized systems may offer cost savings, distributed systems tend to be more resilient in the face of disruptions. Each system type has its advantages and trade-offs, making the choice dependent on specific requirements and priorities.
Whate are distributed energy resources?4 answersDistributed energy resources (DER) are smaller generation units located on the consumer's side of the meter. These resources include battery storage, wind turbines, and photovoltaic (PV) solar energy systems. DER systems contribute to improved operation of electrical power systems by providing a reliable and almost uninterrupted power supply to the load. They are being increasingly accepted for powering nodes, especially in outdoor wireless sensor systems, due to the regularity and dependability of solar energy. The integration of DER, such as PV systems, wind energy systems, and electric vehicles, aims to reduce total power loss, total cost, and emissions in the source network. DER installations, including residential PV systems and EVs, are emerging technologies in the electric grid sector, creating new types of assets for utilities and changing the landscape of power system operation.
What are the distribution and Management Systems used in Multimedia for parallel and distributed computing?5 answersDistribution and management systems used in multimedia for parallel and distributed computing include a computer-implemented method for distributed management of computing resources, a packet distribution method and a packet distribution management apparatus for parallel packet processing, a distribution management apparatus for rendering and distributing video data to communication terminals, a management method executed by a management apparatus that manages a plurality of information processing apparatuses, and a media distribution system and method incorporating parallel delivery of media content. These systems and methods enable efficient utilization of computing resources, high-performance application affinity, conversion and distribution of video data, management of information processing apparatuses, and secure distribution of media content.
What is the role of a centralized distribution model in the Premier League?4 answersA centralized distribution model in the Premier League plays a role in generating high income for the clubs in the league by collectively selling an attractive televised football product. The Premier League is known for being one of the most competitive football leagues in the world, with many goals being scored in each match. Factors such as shots on target, corners, and red cards can affect the number of goals scored by the home team in their matches. By using a centralized distribution model, the league can negotiate and sell the television rights for substantial amounts of money, making it the second wealthiest sporting league in terms of TV rights annual income. This centralized distribution system allows for the centralized storage and management of data and ensures safety, secrecy, and anti-virus protection.
What are the main differences between decentralized and centralized computing environments?3 answersDecentralized computing environments differ from centralized computing environments in several ways. In decentralized environments, the infrastructure is built on top of decentralization, challenging the legacy tools developed for centrally managed cloud-based infrastructures. Decentralized computing is better adapted to ethical constraints and offers advantages in terms of scalability and fault tolerance compared to centralized computation. On the other hand, centralized approaches lack privacy and control for users, have high costs, and bad performance, making them unsuitable for decentralized data spaces prevalent in various industries. Decentralized computing environments also involve caching significant amounts of data and require frameworks for joint computation scheduling, caching, and request forwarding. By combining the advantages of both architectures, a hybrid approach can overcome the limitations of centralized and decentralized systems, providing a decentralized infrastructure for secure and efficient data sharing and processing.
What is better centralized or decentralized approach for complex projects?3 answersA centralized or decentralized approach for complex projects depends on the specific context and requirements of the project. Both approaches have their strengths and limitations. Centralized formation, where the project issuer forms the team based on individual agents' offers, provides control and coordination but may limit flexibility and innovation. On the other hand, decentralized formation, where agents themselves form a consortium, allows for flexibility and adaptability but may pose challenges in terms of stability and coordination. An integrative systemic approach that combines the strengths of both approaches may be more effective in managing complex projects. This approach allows for continuous assessment of the situation and the development of holistic solutions, providing flexibility while retaining the ability to regulate control over the system. The choice between centralized and decentralized approaches should be based on a careful evaluation of the project's characteristics and requirements.
