which is the biggest unit for computer data storage ?

Correct option is D

The correct answer is: (d) Tera Byte

Explanation:
A Tera Byte (TB) is the largest unit listed for computer data storage. It is equal to 1,000 gigabytes (GB) or 1 trillion bytes.

Here’s how the units compare:

• 1 Kilo Byte (KB) = 1,000 bytes
• 1 Mega Byte (MB) = 1,000 KB = 1,000,000 bytes
• 1 Giga Byte (GB) = 1,000 MB = 1,000,000,000 bytes
• 1 Tera Byte (TB) = 1,000 GB = 1,000,000,000,000 bytes

Therefore, a Tera Byte is the largest unit among the options provided.
