Bit how many bytes

The name is a portmanteau of binary digit. How many bits in 1 byte? Convert Reverse Random. What is byte? What is bit? How calculate b. Computer storage and memory is often measured in megabytes MB and gigabytes GB. A medium-sized novel contains about 1 MB of information. Similarly, one 1 GB is 1, MB, or 1,,, xx bytes. A petabyte PB is 1, TB. Indiana University is now building storage systems capable of holding petabytes of data. An exabyte EB is 1, PB. A zettabyte ZB is 1, EB.

Finally, a yottabyte YB is 1, ZB. Many hard drive manufacturers use a decimal number system to define amounts of storage space. As a result, 1 MB is defined as one million bytes, 1 GB is defined as one billion bytes, and so on. Since your computer uses a binary system as mentioned above, you may notice a discrepancy between your hard drive's published capacity and the capacity acknowledged by your computer. For example, a hard drive that is said to contain 10 GB of storage space using a decimal system is actually capable of storing 10,,, bytes.

A gigabyte is 1,,, 2 30 bytes. A terabyte is 1,,,, 2 40 bytes, 1, gigabytes, or 1,, megabytes. A petabyte is 1,,,,, 2 50 bytes, 1, terabytes, 1,, gigabytes, or 1,,, megabytes. An exabyte is 1,,,,,, 2 60 bytes, 1, petabytes, 1,, terabytes, 1,,, gigabytes, or 1,,,, megabytes. A zettabyte is 1,,,,,,, 2 70 bytes, 1, exabytes, 1,, petabytes, 1,,, terabytes, 1,,,, gigabytes, or 1,,,,, megabytes.

A yottabyte is 1,,,,,,,, 2 80 bytes, 1, zettabytes, 1,, exabytes, 1,,, petabytes, 1,,,, terabytes, 1,,,,, gigabytes, or 1,,,,,, megabytes. As of , there are no approved standard sizes for anything bigger than a yottabyte.

However, the two proposed standards are hellabyte or brontobyte. Calculating the above values is simple once you know the values of each of the above sizes. For example, in the gigabyte section above, we know that 1 gigabyte is equal to 1, megabytes.
