Qno$1$ With the Active Object design pattern, the order of method execution follows the order of method invocation.

True or False

Qno $2$Which of the following is true about a Thread?

A thread is a static entity made up of program statements.

A thread can NOT has its own data and status.

A thread can be associated with more than one process in the same time.

A thread allocates part of the process$$s resources for its needs.

Which of the following is true about Concurrency Architecture?

Special hardware architecture needed to perform multi$-$threading.

Another term for multi$-$processing, system with more than one CPU.

The concurrency architecture identifies the threads of execution, the allocation of software elements to those threads, specifies how the threads will be scheduled, and defines how resources will be shared among them.

A platform $($Operating System plus hardware$)$ specialized for running multi$-$threaded applications.

Which of the following is true about a parallel system?

It gives the appearance of several tasks executing at once.

It can improve performance by a factor of n$,$ where n is the number of CPU$$s in the system.

It can only run Java and Python programs.

It requires a multiple CPU system.

Question $7$

$1$ Point

Which of the following suggests the use of a Monitor Object pattern?

When Multiple threads of control accessing the same object concurrently and we want to ensure that only one method at a time runs within an object.

When we want to decouple asynchronous and synchronous service processing in concurrent systems, to simplify programming without unduly reducing performance.

In an event$-$driven application where multiple service requests arriving on a set of event sources must be processed efficiently by multiple threads that share the event sources.

When we want to decouple method execution from method invocation.
