new Quiz on introduction to Distributed Systems

What is a distributed system defined as?

• A system where components never interact

• A system with multiple computers but no interconnections

• A system where components communicate by passing messages

• A system with a single computer handling all tasks

What are some trends influencing the development of distributed systems?

• Limited use of mobile devices

• Decrease in network connectivity

• Rise of standalone computing

• Pervasive networking and modern internet

How can performance bottlenecks be avoided in scalable distributed systems?

• By reducing the number of users

• By implementing distribution and replication techniques

• By increasing the number of centralized servers

• By limiting the resources available

What is the role of transparency in distributed systems?

• To confuse users about system operations

• To hide the separation of components from users

• To slow down system performance

• To limit user access to resources

What is the main goal of middleware in distributed systems?

• To limit scalability

• To provide a uniform computational model

• To introduce more heterogeneity

• To mask failures

What are the consequences of using replication and caching in scalable distributed systems?

• Increased complexity and reduced performance

• Improved performance and reduced redundancy

• Enhanced fault tolerance and improved reliability

• Decreased scalability and increased cost

What are the challenges faced by distributed computing systems?

• Absence of concurrency

• Failure handling

• Lack of security concerns

• Homogeneity in networks

What is the purpose of a distributed transaction system?

• To wrap multiple requests into a single larger request

• To avoid resource sharing

• To execute requests independently

• To limit communication between components

What is the main goal of cluster computing systems?

• To avoid parallel processing

• To reduce computational resources

• To limit the number of connected computers

• To run single programs on multiple machines

What are the nonfunctional requirements affecting the quality of service in distributed systems?

• Heterogeneity, openness, and concurrency

• Reliability, security, and adaptability

• Failure handling, transparency, and quality of service

• Performance, scalability, and transparency
