tebibit
Học thuậtThân thiện
A computer scientist explains that a tebibit is a large unit of digital information.
Definition
- Noun:
- A unit of digital information or computer storage: A tebibit is a specific multiple of the bit, the most basic unit of information in computing. It is precisely equal to 1,099,511,627,776 bits, which is 2 to the 40th power (2^40) or 1024 gibibits.
Usage
- The term "tebibit" is used primarily in technical contexts to express data transfer rates, storage capacities, or memory sizes using binary (base-2) prefixes, as standardized by the International Electrotechnical Commission (IEC). It distinguishes binary multiples from decimal-based metric prefixes.
- Standard Abbreviation: Tibit or Tib.
- Common Contexts: Describing the capacity of high-performance computer memory (RAM), the size of very large datasets, or the speed of advanced network interfaces.
Examples
- Noun:
- The new server is equipped with 2 tebibits of high-speed RAM.
- A tebibit is equivalent to 1024 gibibits.
- The data pipeline can transfer information at a rate of one tebibit per second.
Advanced Usage
- Binary vs. Decimal Prefixes: A "tebibit" (Tibit) is part of the binary prefix system (kibi-, mebi-, gibi-, tebi-). It is distinct from the metric/decimal "terabit" (Tbit), which equals 1,000,000,000,000 (10^12) bits. This distinction is crucial for precise technical specifications.
- Relationship to Bytes: While a tebibit measures bits, storage is often discussed in bytes. One tebibyte (TiB) is equal to 8 tebibits (Tibit).
Variants and Related Words
- Tebibyte (TiB) (noun): A unit of digital information equal to 1024 gibibytes or 2^40 bytes (1,099,511,627,776 bytes). It is the byte-based counterpart to the tebibit.
- Gibibit (Gibit) (noun): A unit of information equal to 1024 mebibits or 2^30 bits. 1024 gibibits equal one tebibit.
- Terabit (Tbit) (noun): A decimal unit of information equal to 1,000,000,000,000 (10^12) bits. Not to be confused with the binary tebibit.
Synonyms
- 2^40 bits: A mathematical expression defining the same quantity.
- 1024 gibibits: An equivalent definition using the next smaller binary unit.
Related Phrases
- Tebibit per second (Tibit/s or Tibps): A unit of data transfer rate equal to one tebibit of data transmitted per second.
- The research network achieved a sustained throughput of several tebibits per second.
