<h2>password method</h2>

Explanation:

Rootkit virus is one type of virus which is hidden about its existence and tries to affect the maximum number of system.

Password method: This is a graphical method to identify the text hidden in the signature and confirming that it is not a robot or any other system to protect the system from hacking. This would be really hard-to-read and thus ensures safety.

Antivirus software: This is a system to protect the system, when the virus tries to attack the system. An indication will be given through the software to the user.

If there are 8 opcodes and 10 registers, a. What is the minimum number of bits required to represent the OPCODE? b. What is the
Nimfa-mama [501]

Answer:  

For 32 bits Instruction Format:

OPCODE   DR               SR1                   SR2      Unused bits

a) Minimum number of bits required to represent the OPCODE = 3 bits

There are 8 opcodes. Patterns required for these opcodes must be unique. For this purpose, take log base 2 of 8 and then ceil the result.

Ceil (log2 (8)) = 3

b) Minimum number of bits For Destination Register(DR) = 4 bits

There are 10 registers. For unique register values take log base 2 of 10 and then ceil the value.  4 bits are required for each register. Hence, DR, SR1 and SR2 all require 12 bits in all.  

Ceil (log2 (10)) = 4

c) Maximum number of UNUSED bits in Instruction encoding = 17 bits

Total number of bits used = bits used for registers + bits used for OPCODE  

     = 12 + 3 = 15  

Total  number of bits for instruction format = 32  

Maximum  No. of Unused bits = 32 – 15 = 17 bits  

OPCODE                DR              SR1             SR2              Unused bits

  3 bits              4 bits          4 bits           4 bits                17 bits

Use the values in the range A7:A8 to extend the list of years to the range A9:A11. 3. Use AutoFill to fill the range A9:H11 with
jok3333 [9.3K]

Answer:

Question is incomplete and it needs a proper XL sheet image and more details. I have assumed and answered this question.

1. Use the values in the range A7:A8 to extend the list of years to the range A9:A11

Ans : <em>Use Ctrl + select A7: A8 and drag till A9: A11 : This will extend the list </em>

<em />

<em>2. </em>Use AutoFill to fill the range A9:H11 with the formatting from the range A7:H8.

Ans : Apply format immediately to the cells A9: H11 below with the help of Auto Fill Handle. Using Auto fill button we can able to a cell format to the cell bellow of active cell by just double clicking on the auto fill button.

3. In cell B8, create a formula without using a function that multiplies the value in cell B7 by the value in cell B6 and then adds the value in B7. Update the cell reference to cell B6, from a relative reference to a mixed reference by making an absolute reference to row 

Ans : =($B7*$B6)+$B7

4. Copy the formula from cell B8 to the range B9:B11 and then copy the formulas from the range B8:B11 to the range C8:H11.

Ans:

1. Select the cell B8 that contains which has formula to be copied

2. Click inside the formula bar to activate it and select the entire formula by using mouse and keyboard.

3. Copy the selected formula and press Esc to deactivate the formula bar.

4. Select the cell  B9 : B11 in which you want the copy of the formula to appear.

5. Most range names refer to absolute cell references. This means that when you copy a formula that uses a range name, the copied formula will use the same range name as the original.

6. Paste the formula by using references.

7. Repeat the steps of 1 to 6 for B8:B11 for range C8:H11.

5. Switch to the Cost Estimates worksheet. In cell A9, create a formula using the AVERAGE function that calculates the average of the values in the range A5:A7, then copy your formula to cell D9.

Ans : =AVERAGE(A5:A7) and Copy it to D9 using answer given in 4.

Write a sequence of statements that create a file named "greeting" and write a single line consisting of "Hello, World!" to that
tia_tia [17]

Answer:

The solution code is written in Python 3 as below:

  1. outfile = open("greeting.txt", "w")
  2. outfile.write("Hello World")
  3. outfile.close()

Explanation:

To create a simple text file in Python, we can use Python built-in function, <em>open()</em>. There are two parameters needed for the open() function,

  1. the file name and
  2. a single keyword "w". "w" denote "write". This keyword will tell our program to create a file if the file doesn't exist.

The statement <em>open("greeting.txt", "w")</em> will create a text file named "<em>greeting.txt</em>" (Line 1)

To fill up the content in the greeting.txt, we use <em>write()</em> method. Just include the content string as the argument of the <em>write()</em> method. (Line 2)

At last, we use <em>close() </em>method to close the opened file,<em> outfile</em>. This will release the system resource from the<em> outfile.</em>

Which of the following are examples of algorithms? (Select all that apply, if any do.)
Travka [436]

Answer:

A. The mathematical formula for finding the area of a circle.

D. Instructions for setting up a new DVD player

E. A series of steps that moves a "lighting bot" around to turns on lights.

Explanation:

Algorithm is a systematic procedure (or process) that produces the answer to a question or the solution of a problem in a finite number of steps.

Option A is an algorithm. The mathematical formula for finding the area of a circle gives a solution to a problem. The problem is finding area of a circle and the formula gives the step by step procedure finding the area of a circle.

Option B is not an algorithm. Option B just provide a list of your favourite animals and it doesn't answer a question we know about.

Option C is not an algorithm. A problem statement is still a problem with no solution whereas algorithm provides solution

Option D is an algorithm. It provides the step by step procedures for setting up a new DVD player

Option E is an algorithm. It provides a series of steps that moves a lighting bot around to turns on lights, so it provides a solution.
