Abbreviated PB. Either 1 quadrillion bytes or 1,125,899,906,842,624 bytes. hysical Memory - Memory actually present in the system, as opposed to virtual memory. A computer might have only 4 megabytes (MB) of RAM but support a virtual memory of 20 MB.

a billion megabytes, or about a quadrillion books the size of this one

a large drive, one million gigabytes big

a million gigabytes, and is roughly equivalent to eight times the information in the Library of Congress

a unit of measurement equal to one million gigabytes of information

a unit of measurement in computers of approximately one thousand million million (American quadrillion) bytes

a unit of measurement in computers of one thousand million million ( short-scale quadrillion ) bytes

One Petabyte (PB) is 1024 Terabytes (TB), it is also 1000 Terabytes. The information in two petabytes would be equivalent to all the information stored in all the academic research libraries in the USA.

250 (2 to the 50th power) bytes.

An exabyte is 1000 petabytes. A petabyte is 1000 terabytes. A terabyte is 1000 gigabytes. A gigabyte is 1000 megabytes. A megabyte is 1000 kilobytes. A kilobyte is 1000 bytes. A byte is 8 bits. A bit is either a 0 or a 1, which is true or false, on or off symbolically. Anything that is 1000 of something is not 1000 of it literally. For example, a megabyte is not really 1000 kilobyte, but is close. Most memory names (exa peta tera giga mega kilo) are 1024 of the name lower than them, but it's usually rounded off to 1000.

About one thousand terabytes (one million gigabytes...)

A unit of measure consisting of one quadrillion bytes (1,000 terabytes).

1024 Terabytes or 1 125 899 906 842 624 bytes (2** 50 bytes)

This is 2^50 bytes. One thousand terabytes/one million gigabytes/one billion megabytes/one trillion kilobytes/one quadrillion bytes (approximately).

1000 Terabytes, or 1 million Gigabytes. You don't need it yet, but isn't it nice to know they've thought up a name for it

one petabyte is approximately 1000 terabytes or one million gigabytes.

2**50 (hex 4,000,000,000,000) bytes of data, i.e. 1,125,899,906,842,620 bytes.

One Petabyte (PB) = 1,000,000,000,000,000 bytes (decimal) 1,125,899,906,842,624 bytes (binary)

One thousand terabytes or One million gigabytes

A measure of data size. One petabyte is equivalent to 1,000 terabytes.

1 Petabyte equal to 1024 terabytes or approx. 1,000,000,000,000,000 bytes. 1 PB has the value of 2 to the power of 50.

A petabyte' (derived from the SI prefix peta- ) is a unit of information or computer storage equal to one quadrillion bytes. It is commonly abbreviated PB. Because of a traditional inconsistency, "petabytes" are often intended to mean pebibytes in common speech.
