Quiz on Distributed Operating Systems

What is a characteristic of a multi-processor system?

• It cannot increase overall system performance.

• It allows multiple processors to work together concurrently.

• It contains only one CPU.

• It is limited to single-threaded applications.

What defines a distributed system?

• A system that only serves one user at a time.

• A system that operates without any network connection.

• A collection of autonomous computers linked by a network.

• A single computer with multiple CPUs.

Which architecture organizes the system into hierarchical layers?

• Event Based Architecture

• Layered Architecture

• Data Centred Architecture

• Object Based Architecture

In Object Based Architecture, how do objects communicate?

• Through method calls.

• By using shared global variables.

• By sending emails to each other.

• Through direct memory access.

What is the focus of Data Centred Architecture?

• Central management of application logic.

• Central management and utilization of data.

• Event-driven interactions.

• Decoupling of components.

What are Event Producers in Event Based Architecture?

• Components that store data.

• Components that manage resources.

• Components that consume events.

• Components that generate events.

What is a key feature of Loose Coupling in Event Based Architecture?

• Direct calls are preferred over events.

• All components must be on the same server.

• Producers and consumers interact through events.

• Producers and consumers are tightly integrated.

Which mechanism is used for object interaction in Object Based Architecture?

• Remote Procedure Call (RPC)

• Shared Memory Access

• Synchronous Data Transfer

• Direct Memory Access (DMA)

What is the role of Event Channels in Event Based Architecture?

• To store data permanently.

• To transmit events between producers and consumers.

• To create user interfaces.

• To manage CPU resources.

What does Layered Architecture promote?

• Single-layered systems.

• Direct interaction between all layers.

• Complexity in system design.

• Separation of concerns.
