ప్రశ్న 2
Using the binary convention in which 1 KB = 1024 bytes, how many bytes are contained in 2 KB?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• Under the binary convention, 1 KB = 1024 bytes.
• Therefore, 2 KB = 2 × 1024 = 2048 bytes.
• The value 2000 corresponds to multiplying by 1000 rather than by the binary conversion factor specified in the question.
• Therefore, 2 KB = 2 × 1024 = 2048 bytes.
