Bit (ALM157S)

Written by: Newton C. Braga
Category: Banco de Informaciones - Almanaque

 

Bit es una contracción de Binary Digit o Dígito Binario, consistente en la menor cantidad de información, o en la unidad de información. Esta unidad se utiliza tanto en computación como en telecomunicaciones y en la teoría de la información. El principal múltiplo del bit es el byte, que consiste en la agrupación de 8 bits. También se utiliza en algunos casos el nibble que consiste en la agrupación de 4 bits. Los bytes también se llaman octetos. En la tabla siguiente damos algunos múltiplos del bit y del byte, observándose que 1 kb (kilo-bit) corresponde exactamente a 1 000 bits pues los prefijados quilo, mega, etc son válidos para el SI en la base 10. Para la base 2 hubo una nueva estandarización del IEC que puede ser encubierta en el verbo "byte" (consulte). En la nueva tabla, 1 kilobit es abreviado por 1 Kib y vale 1 024 bits, siendo el valor indicado para la base 2. En la tabla de potencias de 2 dada adelante, se pueden ver los valores exactos de bits para los múltiplos.


 

 

Los Múltiples y los Derivados del BIT

bit = unidad de información digital - 0 o 1

byte = conjunto de 8 bits

bps = bits por segundo

Kbps = kilobits por segundo = 1000 bits por segundo

Mbps = Megabits por segundo = 1 000 000 bits por segundo

Gbps = Gigabits por segundo = 1 000 000 000 (mil millones) de bits por segundo

Tbps = Terabits por segundo = 1 000 000 000 000 (un billón) de bits por segundo

Pbps = Petabits por segundo = 1 000 000 000 000 000 (2 elevado a 50) bits por segundo

Ebps = Exabits por segundo = 1 000 000 000 000 000 (2 elevado a la potencia 60) bits por segundo

Zbps = Zetabits por segundo = 1 000 000 000 000 000 000 (2 elevado a 70) bits por segundo

Ybps = Yotabits por segundo = 1 000 000 000 000 000 000 000 (2 elevado a 80) bits por segundo
