The first practical implementation of Remote Procedure Call wa on Unix called the Sun's RPC
The Remote Procedure Call could be described as a programming model which allows interaction between apllications, usually between server and client.
The Remote Procedure Call could be related closely to work just like a function call, as arguments or parameters are passed and ability to accept response ls enabled.
The Remote Procedure Call is usually used in the interaction between network applications.
Therefore, the first practical implementation of RPC is called Sun's RPC

Answer:
It depends upon the programming language that you are working on, and you can set your own error message using the try catch option. As an example, suppose you are working on the C#. Code like below can be added:
using System;
class MainClass {
static void Main(string[] args) {
int a = 5;
int b= 0;
int c= 100/2;
console.WriteLine(c);
try {
int d = a / b;
} catch (DivideByZeroException err) {
Console.WriteLine(err);
}
}
}
System.DivideByZeroException: Attempted to divide by zero.
This will give the above error message. And this is an error message by the system. We can also have a user-defined error message.

Answer:
In a rule to disallow connection silently, the action you would use is "Drop" (b).
Explanation:
When you use the "Drop" action in a rule, it means that any incoming connection matching the rule will be silently discarded or ignored. The connection will not receive any response or acknowledgement that it has been dropped. This can be useful in scenarios where you want to block unwanted or malicious traffic without alerting the sender.
For example, let's say you have a firewall configured with a rule that drops all incoming connections from a specific IP address. If a connection attempt is made from that IP address, the firewall will simply drop the connection without sending any response back. The sender will not receive any indication that the connection was dropped, which can help protect your network from potential threats.
It's important to note that the "Drop" action differs from the "Reject" (c) action. While "Drop" silently discards the connection, "Reject" sends a response back to the sender indicating that the connection has been rejected. This can be useful in situations where you want to inform the sender that their connection was not allowed.
In summary, the "Drop" action in a rule is used to disallow connection silently. It silently discards incoming connections without sending any response back to the sender.
b. Facebook
c. NPR Broadcast
d. Time Magazine
Answer:
The answer is option d.
Explanation:
The 'querySelectorAll' function enables you to extract the list of items that fit the CSS selector you choose. It's just a way to find JavaScript components. It is very adaptable and enables you to search for tags, classes, IDs, combinations of parent/child, attributes, etc.
In other words, we can say that the querySelectorAll() method returns all the matches. and other options are not correct that can be described as follows:
