A terabyte is approximately equal to about how many bytes?

A terabyte is approximately equal to about how many bytes?

• A. One billion
• B. One trillion
• C. One quadrillion
• D. One hundred billion

Answer: (B)

A terabyte is a very large unit of digital information. In the common decimal convention used for storage capacities, 1 terabyte equals 10^12 bytes, which is 1,000,000,000,000 bytes—approximately one trillion bytes. So one trillion is the best match among the options. (There’s also a binary measure, 1 TiB = 2^40 bytes ≈ 1.0995×10^12, but the decimal value is the standard reference for a terabyte.)
