Which of the following requests information stored on another computer?

In our interconnected world, accessing and sharing information stored on another computer is a common occurrence. There are various methods and protocols that allow us to retrieve data from remote computers. However, knowing which of these options specifically requests information stored on another computer is key. Let’s explore the answer and provide some clarity.

Answer: **Remote Procedure Call (RPC)**

Remote Procedure Call (RPC) is the option that specifically requests information stored on another computer. RPC is a communication protocol that enables a computer program to call a subroutine or procedure located on another computer without being aware of the underlying network details. By using RPC, a program can request and receive data from a remote computer as if it were stored locally.

RPC is widely used in distributed computing environments, where applications and data are distributed across multiple computers. It allows programs to divide tasks and leverage the collective power of multiple machines. With RPC, a program can seamlessly access information stored on another computer without having to physically transfer the data.

Now, let’s address some related frequently asked questions to further enhance our understanding of this topic:

1. How does Remote Procedure Call (RPC) work?

RPC follows a client-server architecture. The client sends a request to the server by invoking a procedure call. The server receives the request, executes the requested procedure, and sends the result back to the client.

2. What are some examples of protocols that use RPC?

Some examples of protocols that use RPC include DCOM (Distributed Component Object Model), ONC RPC (Open Network Computing Remote Procedure Call), and gRPC (Google Remote Procedure Call).

3. Can RPC be used over the internet?

Yes, RPC can be used over the internet. However, it requires specific configurations and security measures to ensure the confidentiality and integrity of the transmitted data.

4. Is Remote Procedure Call the only method to request information from another computer?

No, there are other methods to request information from another computer, such as HTTP (Hypertext Transfer Protocol), FTP (File Transfer Protocol), SSH (Secure Shell), and more. Each method has its own purpose and characteristics.

5. Does RPC only work between computers?

No, RPC can also be utilized within a single computer, where different processes communicate with each other using the RPC mechanism.

6. Is RPC limited to a specific operating system or programming language?

RPC is not limited to a specific operating system or programming language. It is a general communication protocol that can be implemented on various platforms and programming languages.

7. Can RPC be used for real-time applications?

RPC can be used for real-time applications, depending on the latency and network conditions. However, it may not be the best choice for extremely time-sensitive tasks due to the overhead involved in remote procedure calls.

8. What are some alternatives to RPC?

Some alternatives to RPC include messaging systems like AMQP (Advanced Message Queuing Protocol), event-driven architectures using message brokers, and RESTful APIs (Representational State Transfer).

9. Does RPC require authentication?

Authentication is an important aspect of RPC to ensure secure communication between client and server. Authentication mechanisms such as username/password, certificates, or token-based authentication can be employed.

10. Are there any security risks associated with RPC?

Like any network communication, RPC carries certain security risks. These risks include potential vulnerabilities in the implementation, unauthorized access to sensitive data, and the possibility of remote code execution if not properly secured.

11. Can RPC be used for inter-process communication?

Yes, RPC can be used for inter-process communication (IPC) within a single computer. Applications or processes running on the same machine can communicate with each other using RPC mechanisms.

12. How does RPC compare to RESTful APIs?

RPC and RESTful APIs serve different purposes. RPC focuses on invoking procedures or methods on remote computers, while RESTful APIs enable access and manipulation of resources over HTTP using standard request methods like GET, POST, PUT, and DELETE. The choice between them depends on the specific requirements and design of the application.

In conclusion, when it comes to requesting information stored on another computer, **Remote Procedure Call (RPC)** is the option that fulfills this purpose. By leveraging RPC, programs can seamlessly communicate with remote computers and retrieve data as needed. Understanding the different protocols and methods available allows us to choose the most appropriate approach for our specific requirements.
