Definition
- Noun:
- A unit of digital information: A 'pebibit' is a specific measurement unit in computing and data storage. It represents a quantity of information or data capacity.
- Equal to 2^50 bits: Its precise mathematical definition is 1,125,899,906,842,624 bits (which is 1024 tebibits or 2 raised to the power of 50).
Usage
- The term 'pebibit' is used in technical contexts, particularly in computer science, data storage, and telecommunications, to specify very large amounts of digital data. It is part of the binary prefix system (IEC 60027-2 standard) which is based on powers of two, distinguishing it from the decimal-based 'petabit'.
Examples
- Noun:
- The new solid-state drive has a total storage capacity of one pebibit.
- Data transfer rates for the network backbone are measured in pebibits per second.
- One pebibit is equivalent to 1,024 tebibits.
Advanced Usage
- "Pebibit" vs. "Petabit": It is crucial to distinguish a 'pebibit' (Pibit or Pib) from a 'petabit' (Pbit or Pb). A pebibit is 2^50 bits (1,125,899,906,842,624 bits), while a petabit is 10^15 bits (1,000,000,000,000,000 bits). The pebibit is approximately 12.6% larger than the petabit.
- For accurate engineering specifications, the system's memory was described as 2 pebibits, not petabits.
Variants and Related Words
- Pebibyte (PiB): A related unit of digital information. One pebibyte is equal to 8 pebibits or 2^50 bytes.
- Tebibit (Tibit or Tib): A smaller unit. 1,024 tebibits equal one pebibit.
- Exbibit (Eibit or Eib): A larger unit. One exbibit is equal to 1,024 pebibits.
Synonyms
- Pibit (Abbreviation): The standard abbreviation for pebibit.
- Pib (Abbreviation): An alternative abbreviation.
Related Phrases
- Pebibit per second (Pibit/s or Pib/s): A unit of data transfer rate, indicating the number of pebibits transferred in one second.
- The experimental data link achieved a speed of one pebibit per second.
Noun
- a unit of information equal to 1024 tebibits or 2^50 bits
