# What is the largest unit of storage in a computer

**What is a Geopbyte?**

One geopbyte is equal to 10^{30} bytes or a thousand brontobytes.

**What is a Brontobyte?**

One brontobyte is equal to one quadrillion terabytes. And a brontobyte is smaller than a geopbyte. A thousand brontobytes equal to one geopbyte. And there are one thousand yottabytes in a brontobyte.

**What is a Yottabyte?**

One yottabyte is equal to 1000^{8} bytes or 10^{24} bytes. That also means one septillion bytes. It is equivalent to 1,000 zettabytes or one trillion terabytes as well.

Also, remember that yottabytes are used in decimal; yobibytes are used in binary. The unit symbol of yottabyte is YB; the unit symbol of Yobibyte is YiB.

**What is a Zettabyte?**

There are 1000^{7} bytes or 1,000 exabytes in a zettabyte in decimal system. Also, we can say that one zettabyte is 1024^{7} in binary. The unit symbol of Zettabyte is ZB; the unit symbol of Zebibyte is ZiB.

**What is an Exabyte?**

One exabyte is equivalent to one quintillion bytes or 1,000 petabytes. That also means 1000^{6} bytes in decimal and 1024^{6} bytes in binary. The unit symbol of Exabyte is EB.

**What is a Petabyte?**

A petabyte is a unit of digital information equals one thousand million million bytes. 1 petabyte is also equivalent to 1,000 terabytes or 10^{15} bytes. That also means 1000^{5} bytes or 1000^{2} gigabytes in decimal system. The unit symbol of Petabyte is PB.

Gigabyte is one of the most used units of digital information. Petabytes are one million times bigger than gigabytes. 1 PB is 1,000,000 GB in decimal and 1 PB is 1,048,576 GB in binary.

A terabyte is another digital information measurement unit and it is one thousand times bigger than a gigabyte. That means 10^{12} bytes. On the other hand, 1 PB is 1,000 TB in decimal and 1 PB is 1,024 TB in binary. As you can see, a petabyte is one thousand times bigger than a Terabyte.
