Detailed explanation-1: -Tera-means 1, 000, 000, 000, 000; a Terabyte is a trillion bytes. Peta-means 1, 000, 000, 000, 000, 000; a Petabyte is 1, 000 Terabytes.
Detailed explanation-2: -A petabyte is a measure of memory or data storage capacity that is equal to 2 to the 50th power of bytes. There are 1, 024 terabytes (TB) in a petabyte and approximately 1, 024 PB make up one exabyte.
Detailed explanation-3: -A petabyte is a collection of about 1 quadrillion bytes, which is around 1, 000 terabytes. In the metric system, peta is a prefix for 1 quadrillion, or 1015. So in some cases, a petabyte is defined as 1 quadrillion, or 1, 000, 000, 000, 000, 000 bytes.
Detailed explanation-4: -Detailed Solution. The correct answer is Terabytes (TB). 1 Petabyte = 1024 Terabytes.
