Find the correct pair from the following :
Answer: B
The correct pair is 1 Megabyte = \(10^{6}\) bytes.
In the decimal (SI) system, each prefix is a thousand times the one before: kilo = \(10^{3}\), mega = \(10^{6}\), giga = \(10^{9}\) and tera = \(10^{12}\). So a megabyte is \(10^{6}\), one million, bytes. (In the binary convention a megabyte is \(2^{20}\) = 1,048,576 bytes, which is close to \(10^{6}\).)
The other pairs are each wrong: a kilobyte is \(10^{3}\), not \(10^{4}\); a gigabyte is \(10^{9}\), not \(10^{12}\), which is a terabyte; and a terabyte is \(10^{12}\), not \(10^{15}\), which is a petabyte.
