Interprocess Communication Online Test

What is Inter Process Communication (IPC)?
A. A process of sharing memory between two processes
B. A process of exchanging messages between two processes
C. A process of running two processes on the same CPU
D. A process of accessing files between two processes
Answer: B. A process of exchanging messages between two processes. IPC is a mechanism that allows two or more processes to communicate and exchange information with each other.

Which of the following is not a type of IPC?
A. Shared Memory
B. Message Passing
C. Remote Procedure Call (RPC)
D. Multithreading
Answer: D. Multithreading. Multithreading is a technique that allows a single process to execute multiple threads concurrently. It is not a type of IPC.

Which IPC mechanism involves the use of a common memory space between two processes?
A. Shared Memory
B. Message Passing
C. Remote Procedure Call (RPC)
D. Semaphore
Answer: A. Shared Memory. Shared memory is a technique where two or more processes share a common memory space to exchange data and communicate with each other.

Which IPC mechanism is used for communication between processes on the same computer?
A. Shared Memory
B. Message Passing
C. Remote Procedure Call (RPC)
D. Semaphore
Answer: A. Shared Memory. Shared memory is the most efficient IPC mechanism for communication between processes on the same computer.

Which IPC mechanism is used for communication between processes on different computers?
A. Shared Memory
B. Message Passing
C. Remote Procedure Call (RPC)
D. Semaphore
Answer: C. Remote Procedure Call (RPC). RPC is a mechanism that allows a process to call a procedure or function in a different process or even on a different computer.

Which of the following is an example of a message passing IPC mechanism?
A. Pipes
B. Semaphores
C. Message Queues
D. Mutexes
Answer: C. Message Queues. Message Queues are an IPC mechanism that allows processes to send and receive messages.

Which of the following is not a characteristic of message passing?
A. Synchronous
B. Asynchronous
C. Blocking
D. Non-blocking
Answer: A. Synchronous. Message passing can be synchronous or asynchronous, but synchronous message passing is not a characteristic of message passing.

Which IPC mechanism can be used for synchronization between processes?
A. Pipes
B. Shared Memory
C. Semaphores
D. Message Queues
Answer: C. Semaphores. Semaphores are a synchronization mechanism that can be used to control access to shared resources between processes.

Which of the following is an advantage of message passing over shared memory?
A. Simpler implementation
B. Higher performance
C. Easier to scale to multiple processors
D. Lower overhead
Answer: C. Easier to scale to multiple processors. Message passing is more scalable than shared memory, especially when there are multiple processors involved.

Which of the following is not an advantage of shared memory over message passing?
A. Lower overhead
B. Simpler implementation
C. Higher performance
D. Easier to debug
Answer: D. Easier to debug. Shared memory can be more difficult to debug than message passing because of the potential for race conditions and other synchronization issues.

Which IPC mechanism provides the highest performance for communication between processes on the same computer?
A. Pipes
B. Shared Memory
C. Message Passing
D. Semaphores
Answer: B. Shared Memory. Shared memory provides the highest performance for communication between processes on the same computer because it eliminates the overhead of message passing.

Which of the following is a disadvantage of message passing compared to shared memory for communication between processes on the same computer?
A. Higher overhead
B. More difficult to implement
C. Lower performance
D. More prone to synchronization issues

Answer: A. Higher overhead. Message passing has a higher overhead compared to shared memory because it involves copying data between processes.

Which of the following is a disadvantage of using Remote Procedure Call (RPC)?
A. It is not secure
B. It is only applicable for communication between processes on the same computer
C. It has a high overhead
D. It is difficult to implement
Answer: C. It has a high overhead. RPC has a higher overhead compared to other IPC mechanisms because it involves marshalling and unmarshalling data between processes.

Which of the following is an example of a synchronous IPC mechanism?
A. Pipes
B. Message Queues
C. Semaphores
D. Signal Handlers
Answer: B. Message Queues. Message Queues can be used for both synchronous and asynchronous communication, but they can also be used in synchronous mode.

Which of the following is an example of an asynchronous IPC mechanism?
A. Shared Memory
B. Message Queues
C. Semaphores
D. Signals
Answer: D. Signals. Signals are a mechanism for asynchronous IPC because they allow a process to notify another process of an event.

Which IPC mechanism is commonly used in multi-threaded applications?
A. Shared Memory
B. Message Passing
C. Mutexes
D. Remote Procedure Call (RPC)
Answer: C. Mutexes. Mutexes are a synchronization mechanism commonly used in multi-threaded applications to protect shared resources.

Which of the following is not a disadvantage of using Shared Memory for IPC?
A. More prone to synchronization issues
B. Difficult to implement
C. Can be less secure
D. Higher overhead
Answer: D. Higher overhead. Shared memory has a lower overhead compared to message passing because it eliminates the need to copy data between processes.

Which of the following is an example of a distributed IPC mechanism?
A. Pipes
B. Shared Memory
C. Message Queues
D. Remote Procedure Call (RPC)
Answer: D. Remote Procedure Call (RPC). RPC is a distributed IPC mechanism because it allows processes to communicate across different computers.

Which IPC mechanism is commonly used in real-time systems?
A. Pipes
B. Shared Memory
C. Message Passing
D. Semaphores
Answer: D. Semaphores. Semaphores are commonly used in real-time systems for synchronization and control of shared resources.

Which of the following is a disadvantage of using Message Passing for IPC?
A. Higher overhead
B. More prone to synchronization issues
C. Less secure
D. More difficult to implement
Answer: A. Higher overhead. Message passing has a higher overhead compared to shared memory because it involves copying data between processes.
