<u>Answer:</u>

  • <em>A. divide the decimal number by the base value 2</em>
  • <em>C. note the remainder separately</em>
  • <em>D. divide by 2 until she gets 0 as the remainder</em>
  • <em>B. collect the digits in the reverse order</em>

<u>Explanation:</u>

When we want to convert decimal number to a binary number first we have divide the given number by 2. The next step is to note the reminder of the number in the side every division so that the reminder value is the binary value. Repeat this until an zero is encountered.

We have to collate all the remainders from last of first and then the collated number is the answer for the given problem.

<em>So the given option can be ordered as, </em>

  • <em>A</em>
  • <em>C</em>
  • <em>D</em>
  • <em>B</em>

lukranit [14]

The BIOS feature that enables a hard drive to read or write several sectors at a time is called IDE block mode

Explanation:

IDE block mode setting speeds up IDE drivers when enabled by allowing multiple sectors to read or write operations. This BIOS feature rushes up hard disk drive passage by transferring many divisions of data per interrupt rather than using the normal single-sector transfer mode.

This mode of transfer is known as block transfers. When block transfers are enabled, depends on the IDE controller, nearly 64 KB of data can be transferred per interrupt.

For this lab you will do 2 things:
zepelin [54]

Answer:

Here is the Python program:

COOKIES_PER_BAG = 40 #sets constant value for bag of cookies

SERVINGS_PER_BAG = 10 #sets constant value for serving in bag

CALORIES_PER_SERVING = 300 #sets constant value servings per bag

cookies = int(input("How many cookies did you eat? ")) #prompts user to input how many cookies he or she ate

totalCalories = cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG)); #computes total calories consumed by user

print("Total calories consumed:",totalCalories) #displays the computed value of totalCalories consumed

Explanation:

The algorithm is:

  • Start
  • Declare constants COOKIES_PER_BAG, SERVINGS_PER_BAG and CALORIES_PER_SERVING
  • Set COOKIES_PER_BAG to 40
  • Set SERVINGS_PER_BAG to 10
  • Set CALORIES_PER_SERVING to 300
  • Input cookies
  • Calculate totalCalories:                                                                                                                       totalCalories ← cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG))
  • Display totalCalories

I will explain the program with an example:

Lets say user enters 5 as cookies he or she ate so

cookies = 5

Now total calories are computed as:

totalCalories = cookies * (CALORIES_PER_SERVING / (COOKIES_PER_BAG / SERVINGS_PER_BAG));  

This becomes:

totalCalories = 5 * (300/40/10)

totalCalories = 5 * (300/4)

totalCalories = 5 * 75

totalCalories = 375

The screenshot of program along with its output is attached.
