Drupady [299]

Answer:

Hi, for this exercise we have two laws to bear in mind:

Morgan's laws

NOT(А).NOT(В) = NOT(A) + NOT (B)

NOT(A) + NOT (B) = NOT(А).NOT(В)

And the table of the Nand

INPUT OUTPUT

A B A NAND B

0 0         1

0 1         1

1 0         1

1 1         0

Let's start!

a.

Input            OUTPUT

A       A     A NAND A

1         1             0

0        0            1

b.

Input            OUTPUT

A       B     (A NAND B ) NAND (A NAND B )

0         0            0

0         1            0

1          0             0

1          1             1

C.

Input            OUTPUT

A       B     (A NAND A ) NAND (B NAND B )

0        0           0

0        1             1

1         0            1

1          1            1

Explanation:

In the first one, we only need one input in this case A and comparing with the truth table we have the not gate

In the second case, we have to negate the AND an as we know how to build a not, we only have to make a nand in the two inputs (A, B) and the make another nand with that output.

In the third case we have that the OR is A + B and we know in base of the morgan's law that:

A + B = NOT(NOT(А).NOT(В))

So, we have to negate the two inputs and after make nand with the two inputs negated.

I hope it's help you.

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.

A penetration tester is experimenting with Network Mapper (Nmap) on a test network as a privileged user. The tester would like t
kondor19780726 [428]

The Network Mapper (Nmap) commands that would be useful on this test network are:

  1. nmap xxx.xxx.x.x -p
  2. nmap xxx.xxx.x.x -A

<h3>What is a penetration test?</h3>

A penetration test can be defined as a cybersecurity technique that simulates a cyber attack against an end user's computer system, so as to scan, identify, test and check for exploitable vulnerabilities in the following:

  • Operating system
  • Web software
  • Host device
  • Network

This ultimately implies that, a penetration test avails an tester the ability to exploit a weakness and potential security threats on a test network as a privileged user, during vulnerability assessments of the system.

<h3>The Network Mapper (Nmap) commands.</h3>

In this scenario, the Network Mapper (Nmap) commands that would be useful on this test network are:

  1. nmap xxx.xxx.x.x -p
  2. nmap xxx.xxx.x.x -A
