The logical expressions are

(X NOR Y ) OR Z ⇒ $(\bar X \bar + \bar Y) + Z$
(A NAND B) AND NOT C ⇒ $(\bar A \bar \cdot\bar B) \cdot \bar C$

<h3>How to determine the logical expressions?</h3>

<u>Logical expression 1</u>

X and Y are linked by the NOR gate.

So, we have:

X NOR Y

The X NOR Y is linked to Z by the OR gate.

So, we have:

(X NOR Y) OR Z

Hence, the logical expression is (X NOR Y ) OR Z ⇒ $(\bar X \bar + \bar Y) + Z$

<u>Logical expression 2</u>

A and B are linked by the NAND gate.

So, we have:

A NAND B

The A NAND B is linked to C by the AND gate.

So, we have:

(A NAND B) AND C

Hence, the logical expression is (A NAND B) AND NOT C ⇒ $(\bar A \bar \cdot\bar B) \cdot \bar C$

What are the possible consequences of intentional virus setting?

natali 33 [55]

<u>The possible consequences of intentional virus setting:</u>

Virus is nothing but desktop or laptop or tablet OS has to do certain process as on its own which diverse other to different process such us stealing the data from desktop or laptop or tablet and making slow the performance of desktop and laptop and tablet.

To avoid or protect the computer there are two type of antivirus.

On desktop or tablet or laptop. (It is called resident firewall).

Internet gateway. (It is called firewall)

So company create virus and to rectify they make money of that process.

To protect our desktop or laptop or tablet from virus we are protected with law. In case due to virus attacked our laptop or desktop or tablet Is effected we can fine the or sent to jail by law.

Drag each label to the correct location on the image.

andrezito [222]

Answer:

1.) Relative cell reference - A1

2.) Absolute cell reference - $D$2

3.) Mixed cel reference - $D2

Explanation:

In Microsoft Excel, cell references are very important and critical when dealing with formula. They can give you what you’re looking for or make your entire worksheet incorrect.

A cell reference is a cell address or a range of cell addresses that can be used in a formula.

There are three types of cell references and they are;

a) Relative reference

b) Absolute reference

c) Mixed reference

A relative cell reference is a cell reference that changes when you copy the formula to other cells. It s usually just a normal cell reference like A1, B2, C3. If a formula with a relative cell reference is copied down to other cells, the formula will change. That is a formula with a relative cell reference changes with respect to the cell which it is copied to.

An absolute reference does not change when you copy the formula to other cells. In absolute references, the dollar sign $ is used to “lock” both the row and column so that it does not change when it is copied to other cells. An example is $D$2.

Using a mixed cell reference, one is trying to see that only either the row or column changes with respect to other cells when they are copied. It is like “locking” either the column or the row while changing the other. Just like from the example, $D2 is a mixed cell reference where only the column is locked such that only the row changes when the formula is copied to other cells.

Consider the clipping of a line segment in two dimensions against a rectangular clipping window. Show that you require only the

Semmy [17]

Answer / Explanation:

Assuming we define the end points as ( x₁ , y₁) and (x₂ , y₂) and the rectangular window edge as ( Xmin ,Ymin and Xmax , Ymax)

The illustration of the above assumption is represented in the diagram below.

Now, suppose the line segment is between the points P₁ = ( x₁ , y₁) , and

P₂ = (x₂ , y₂).

We can then create a line recalling and using parametric form,

P(t) = ( 1 - t) P₁ + tP₂ , t ∈ {0 , 1 },

So, for the X axis, we have,

tₓ = P₁ₓ - x ÷ P₁ₓ - P₂ₓ

We need to note that at this point we need to know the minimum and maximum unclipped values for parameter t from each dimension.

Therefore,

- ( tmin , tmax ) = ( 0,1) means unclipped line

-tmin > tmax means completely clipped out line

– Some other range means partially clipped out line.

Write a function that accepts an argument for a persons name. The method should loop through the number of characters in the nam

MatroZZZ [7]

Answer:

#include <iostream>

#include<string.h>

using namespace std;

void printCharacter(string name){

for(int i=0;name[i]!='\0';i++){

cout<<name[i]<<endl;

}

int main()

{

string name;

cout<<"enter the name: ";

cin>>name;

printCharacter(name);

}

Explanation:

first include the two libraries iostream for input/output and string library for using the string.

then, create the main function and declare the variable type string.

cout instruction is used o display the message on the screen.

cin is used to store the value in the name variable.

after that, call the function. The program control move to the the function. In the function for loop is used to print the character one by one until end of the name.

<span>The statement that "Persons who have been given access to an installation can be counted on to be of no threat" is false. If they are not honest enough, they could become the dangerous staff the company could ever had because he or she has access to everything, files, information, etc. That is why, in selecting a person to be trusted with such responsibility, he or she undergoes an intensive training.</span>
