Diferencia entre megabytes y gigabytes

Las unidades nos ayudan a comprender diferentes cantidades y a mantener un seguimiento de cuánto es una cosa. La información digital también se mide en unidades y algunas unidades estándar se describen utilizando una unidad básica llamada bytes. Un gigabyte está formado por dos palabras Giga y byte. Aquí, Giga significa diez elevados al poder de diez. El uso de prefijos como estos prevalece en la medición, por ejemplo, un kilo es un prefijo que significa mil. En términos de Megabyte y Gigabyte, la palabra base es byte y los prefijos son Mega y Giga respectivamente.

Megabyte vs Gigabyte

La principal diferencia entre Megabyte y Gigabyte es que un megabyte significa 1 millón de bytes de datos, mientras que un gigabyte es mil millones de bytes de datos. Los dos prefijos mega y Giga son multiplicadores con valores de 10 elevados a la potencia de nueve y Giga significa 10 elevados a la potencia de seis respectivamente.

Según la definición de unidades SI ’, se utilizan megabytes 1 millón de bytes pero al calcular diferentes definiciones. Según una definición, un megabyte equivale a dos elevados a la potencia de 20 bytes. Microsoft utiliza la definición para medir la memoria de la computadora. También tiene una definición mixta en la que 1 megabyte equivale a 1000 multiplicado por 1024. Se utiliza para medir la capacidad de un disquete HD.

Un gigabyte es una unidad que también se usa para medir la memoria. Se utiliza para medir la memoria digital. Las unidades SI lo definen como mil millones de bytes, pero también tiene algunas otras definiciones basadas en las mismas bases que los megabytes. Se define en términos de una base de dos elevados al poder de treinta. Microsoft utiliza la definición en términos de base dos para definir la memoria de la computadora.

Tabla de comparación entre megabytes y gigabytes

Parámetros de comparación Megabyte 1.073.741.824.Definición mixta Tiene una definición mixta que equivale a 1000 * 1024.No tiene una definición mixta. Comparación Es una cantidad menor en comparación con Gigabyte Es una cantidad mayor en comparación con Megabyte. Ejemplo Un video de YouTube de 5 minutos con una calidad de 1080p equivale a 100 MB. El tamaño del DVD es de 4.5 GB si es de una sola capa.

¿Qué es Megabyte?

Una unidad utilizada para medir información digital con un valor igual a un millón de bytes se llama megabyte. La unidad básica de medición de la información digital es byte, pero debido a la necesidad de otras definiciones para describir grandes cantidades de información digital, se adoptó megabyte. Megabyte también tiene diferentes definiciones. También se define en términos de una base de dos. Cuando elevamos el poder de dos a veinte, es igual a 1,048,576. El valor es cercano a 1 millón y es utilizado por Microsoft para definir la memoria de la computadora.

La definición mixta de megabytes incluye dos conceptos juntos. En este método, multiplicamos mil con mil veinticuatro. Es igual a 1024000. Este método mixto se utiliza para medir la capacidad del disquete HD. El disco con una memoria de 1.44 MB es igual a 1474560 ( el tamaño es de 3.5 pulgadas ). La diferencia entre la capacidad se debe al hecho de que esta definición se usa para describir la memoria formateada.

Megabyte recibe una definición estándar del sistema internacional de unidades que es igual a 1 millón de bytes, pero el término no es ampliamente aceptado debido a que hay múltiples definiciones como se describió anteriormente. Estas definiciones están en uso debido a convenciones y razones históricas de conveniencia.

¿Qué es Gigabyte?

Gigabyte es otra unidad que evolucionó para medir grandes cantidades. También es un múltiplo de un byte. Un gigabyte es igual a mil millones de bytes, que se define de acuerdo con el Sistema Internacional de Unidades. Microsoft utiliza la definición que utiliza la base dos para definir la cantidad para definir la memoria de la computadora. La definición que utiliza la base 10 se usa estrictamente para definir un gigabyte según las indicaciones de IEC ( Comisión Electrotécnica Internacional ).

El advenimiento del rango de gigabytes causó mucha confusión como prefijos decimales anteriores. La controversia surgió debido a que la especificación gigabyte es menor que las expresadas por los prefijos decimales. El valor de un gigabyte es igual al noventa y tres por ciento de Gibibyte, que según los sistemas operativos de la computadora es menor. Si la especificación en la etiqueta dice que 400 GB es igual a solo 372 Gibibyte. Causa confusión ya que los sistemas operativos informan mebibyte como un gigabyte.

La demanda contra los fabricantes por parte de los consumidores ha terminado a favor de los fabricantes, ya que el tribunal tenía el valor de un gigabyte igual a diez elevado al poder de nueve. El silencio descartó la definición binaria sobre la definición decimal y declaró que era la definición legal.

Diferencias principales entre megabytes y gigabytes

  1. Megabyte y gigabyte son múltiples, el byte, que es la unidad básica para la información digital, pero difieren en los números que definen.
  2. Un megabyte es más pequeño en comparación con un gigabyte, ya que un megabyte solo equivale a 10 elevados a la potencia de seis y un gigabyte es igual a 10 elevados a la potencia de nueve.
  3. Un megabyte se puede definir como un valor mixto que equivale a 1000 multiplicado por 1024, mientras que un gigabyte no tiene esa definición.
  4. La definición legal de un Gigabyte es igual a 10 elevado a la potencia de nueve, mientras que Megabyte no tiene una definición legal como tal.
  5. Se utilizan diferentes versiones de megabytes para definir la información digital, mientras que la definición SI para un gigabyte se considera estándar.

Síntesis

Debido al cambio en el uso y la necesidad de forma condensada para definir grandes cantidades, inventamos una forma diferente de unidades. Megabyte y Gigabyte son ejemplos de tales formas condensadas. La unidad básica para ambos son los bytes. Uno difiere del otro en términos de los prefijos que dan valores diferentes. El mega prefijo no es más que un múltiplo que equivale a 1 millón, mientras que Giga es igual a mil millones. Estas definiciones están de acuerdo con el sistema internacional de unidades y se denominan unidades decimales.

Se utilizan diferentes definiciones, como la definición mixta de megabytes que equivale a 1024000 y se utiliza para definir el almacenamiento del disquete HD. Microsoft utiliza la definición binaria para definir el disco de la computadora de memoria.
