In the digital age we live in today, data is everything. Decimal prefix In byte conversion
Data volumes and storage capacities are an integral part 3
of 21st century technologies. But while computer users Kilobyte(KB) 1000 = 10
measure storage capacities for photos, texts, and videos in Megabyte(MB) 1000000 = 10 6
gigabytes and terabytes, technology giants like Google and Gigabyte(GB) 1000000000 = 10 9
Tesla are already dealing in units of exabyte. 12
According to the decimal system, an exabyte comprises Terabyte(TB) 1000000000000 = 10
18
10 , i.e., one quintillion bytes. A megabyte is made up of Petabyte(PB) 1000000000000000 = 10 15
one million bytes. Around 4 megabytes are required today Exabyte(EB) ……………………………
to save a high-resolution photo. The current largest unit of Zettabyte(ZB) ……………………………
information is the zettabyte. Here are the eight official units
of measurements for byte powers. Yottabyte(YB) ……………………………
Explore through internet and find the number of bytes and
their corresponding exponential form for Exabyte, Zettabyte and Yottabyte.
