Question 17 of 19intermediate🔧 ApplyNumerical4 marks

Check the size of RAM and HDD of a computer in your school. Make a table and write their size in Bytes, Kilobytes, Megabytes and Gigabytes.

Correct Answer

To complete this activity, I checked a computer in our school lab and found the following specifications:

RAM Size: 4 GB

Step 1: Converting 4 GB to MB 4 GB = 4×10244 \times 1024 = 4096 MB

Step 2: Converting 4096 MB to KB 4096 MB = 4096×10244096 \times 1024 = 41,94,304 KB

Step 3: Converting 41,94,304 KB to Bytes 41,94,304 KB = 41,94,304×1024304 \times 1024 = 4,29,49,67,296 Bytes

HDD Size: 500 GB

Step 1: Converting 500 GB to MB 500 GB = 500×1024500 \times 1024 = 5,12,000 MB

Step 2: Converting 5,12,000 MB to KB 5,12,000 MB = 5,12,000×1024000 \times 1024 = 52,42,88,000 KB

Step 3: Converting 52,42,88,000 KB to Bytes 52,42,88,000 KB = 52,42,88,000×1024000 \times 1024 = 5,36,87,09,12,000 Bytes

Explanation

This question tests the student's understanding of memory units and their conversions. The textbook provides the conversion factors in Table 1.1: 1 KB = 1024 Bytes, 1 MB = 1024 KB, and 1 GB = 1024 MB. Students should note that each higher unit is 1024 times the previous unit because computers use binary system. The actual values may vary depending on the computer checked, but the conversion method remains the same.

Solution Steps

  1. Step 1: Identify the RAM and HDD size from the computer (e.g., 4 GB RAM, 500 GB HDD)

  2. Step 2: Use conversion factors from Table 1.1: 1 KB = 1024 Bytes, 1 MB = 1024 KB, 1 GB = 1024 MB

  3. Step 3: Convert GB to MB by multiplying by 1024

  4. Step 4: Convert MB to KB by multiplying by 1024

  5. Step 5: Convert KB to Bytes by multiplying by 1024

  6. Step 6: Present all values in a tabular format
