A Storage is the amount of information storage that such a device, as well as a system, can accommodate is referred to as storage capacity. This crucial assessment is common in consumer-facing IT including in designing enterprise software or even other larger systems to operate normally.

What is a Bit?

A bit, or binary digit, must be the starting point for any basic explanation of computing or telecommunications. This would be the tiniest bit of digital information that can be sent across a network connection. It is the most basic component of every email and text message you end up receiving. A bit is a single unit of digital information that can represent either a zero or a one. The use of bits to encode data dates back to the early punch card systems which permitted the first mechanical system to perform computations. The more bits you are using, the more data you can send. That is, more bits equals better color, sound, video, storage space, memory, and so on. 

What is a Byte?

A byte is a group of bits, usually eight. Bits are grouped into bytes to increase the efficiency of computer hardware, networking equipment, disks, and memory. The numbers 8, 16, 32, and 64 appear frequently in computing literature, owing to the fact that the 8-bit byte is the basic building unit. The key point to remember is that, while relying on your overall system on only two digits may appear to be restricting, these two digits can also be used to represent almost anything.

Did you know?

A Yottabyte (YB) is a digital information storage unit that is used to indicate the size of data. It is the same as a quadrillion gigabytes, 1,000 zettabytes, or one billion (1,000,000,000,000,000,000) bytes. Among all units, the yottabyte has the biggest storage capacity, however, it is only theoretical since Nothing yet is large enough to be measured in yottabytes.  Is that kind of storage capacity even possible? There was nothing that could be assessed on a yottabyte scale. Thus according to Paul McFedries’ book Word Spy, downloading a 1 YB file would take approximately 86 trillion years, although the entire contents of the Library of Congress would take only 10 terabytes.

There are 8 units of data and those are:

  • Kilobyte

A kilobyte is equal to 1,000 bytes (specifically, 2 to the 10th power or, in decimal form, 1,024 bytes)

  • Megabyte

A megabyte (MB) is a unit of data measurement used in digital computers or media storage. One megabyte (MB) is equal to one million bytes (106 or 1,000,000).

  • Gigabyte

a unit of data equal to one billion bytes.

  • Terabyte

A terabyte (TB) is a unit of digital data equivalent to approximately 1 trillion bytes. A terabyte is exactly one trillion bytes in decimal notation (base 10).

  • Petabyte

A terabyte (TB) is a digital data unit equal to approximately 1 trillion bytes. A terabyte is exactly one trillion bytes in decimal format (base 10).

  • Exabyte

Exabytes are one quintillion bytes, one billion gigabytes, or one million terabytes (TB). In comparison to other digital data and storage units, 8 bits equals one byte.

  • Zettabyte

A zettabyte is a type of digital measurement unit. One zettabyte is equivalent to one trillion bytes or one trillion gigabytes.

  • Yottabyte

This is a theoretical storage capacity and data volume measurement equal to 2 to the 80th power bytes, or roughly one million trillion megabytes (MB).
