Answer:
The gates required to build a half adder are :
- AND Gate for Carry.
- XOR Gate for Sum
Explanation:
AND Gate is required for the carry and the XOR gate is required for the sum.
The figures for the gates and the truth tables for the half adder are attached so please refer them for further explanation.
The sum is 1 when one of the input is High or 1 if both the inputs are same then the sum is 0.So this behavior is implemented by X-OR gate.
The carry is High only when both of the inputs are 1.This is implemented by AND-Gate.
Answer:
Permissioned
Explanation:
In this scenario, specified group of banks got together and joined forces by agreeing to use a blockchain for wholesale settlement of all interbank transfers. Thus, this is most likely an example of a permissioned blockchain.
Answer:
Game theory.
Explanation:
In the TV game show Jeopardy! Game theory allows contestant to use a strategy to seek out the hidden Daily Double questions, instead of the more common approach of selecting a single category and selecting questions gradually increasing in the degree of difficulty.
Game theory is the process of using mathematical model in the study of strategic interaction between two or more players in a game or situation having laid down rules and outcomes.
Connections, allow separate systems to communicate directly with each other, eliminating the need for manual entry into multiple systems. They do not entirely eliminate information redundancy, but they do ensure information consistency among multiple systems.
Answer:
Reference
Explanation:
The Reference type variable is such type of variable in C# that holds the reference of memory address instead of value. Examples for reference type are classes, interfaces, delegates and arrays.
We can pass parameters to the method by reference using <em>ref </em>keyword
It’s mandatory to initialize the variable value before we pass it as an argument to the method in c#
For example,
int x = 10; // Variable need to be initialized
Add(ref x); // method call
If you pass parameters by reference in method definition, any changes made to it affect the other variable in method call.
Here's a sample program:
using System;
namespace ConsoleApplication
{
public class Test
{
public static void Main()
{
int i = 10;
Console.WriteLine("i=" + i);
Add(ref i);
Console.WriteLine("i=" + i);
Console.ReadLine();
}
public static void Add( ref int j)
{
j = j + 10;
Console.WriteLine("j="+j);
}
}
}
Output:
i=10
j=20
i=20
