The smallest and most commonly measured units of data storage capacity in computers and other discs are the bit (short for binary digit). The binary value of a bit is equal to either 0 or 1. A group of four bits or half-byte is equivalent to one nibble. Similarly, a group of eight bits are equivalent to one Byte. Generally,  computers manipulate bits in groups of a fixed size, called words.

Smallest and Largest Data Storage Measurement in Computer

Crumb is rarely measured memory unit in a computer. A pair of two bits is called a crumb. Bit stands for Binary digit. It is the smallest memory measurement unit on a computer and some other discs. It stores just 0 or 1. Currently, the largest memory measurement in computers is Yottabyte. But, we have two proposed names for the next levels, namely Hellabyte or Brontobyte (Hellabyte or Brontobyte = 1,024 Yottabytes). So we’re not there yet. As explained above a Hellabyte = 1,024 Yottabytes or, if we measure in the smallest units, it is equivalent to 1,000,000,000,000,000,000,000,000,000 bytes, or 1 x 1027 bytes.
