Q. The fundamental unit of storage in a digital computer is known as a :

A
bit
B
byte
C
nibble
D
megabyte
Solution:
  • In computing and telecommunications, a unit of information is the capacity of some standard data storage system or communication channel, used to measure the capacities of other systems and channels.

  • In information theory, units of information are also used to measure the entropy of random variables and information contained in messages.

  • The most commonly used units of data storage capacity are the bit, the capacity of a system that has only two states, and the byte (or octet), which is equivalent to eight bits.

  • Multiples of these units can be formed from these with the SI prefixes (power-of-ten prefixes) or the newer IEC binary prefixes (power-of-two prefixes).

  • In dimensional analysis, information is considered to be a dimensionless quantity
