MariaJose73Buenos dias, tengo una duda sobre los bits, bytes, KiloBytes, etc….
A ver si alguien me hecha una manita……
Por que: cuando dice que un bus de direcciones de 1 byte el ordenador podrá gestionar 2’8 = 256 posiciones de memoria.
Cuando la tabla de multiplos es:
* 8 bits = 1 byte
* 1 KiloByte o KB corresponde a 2’10 = 1024 Bytes
* 1 MegaByte o MB ” ” (?) = 1024 KB
* 1 GigaByte o GB ” ” (?) = 1024 MB
* 1 TeraByte o TB ” ” (?) = 1024 GB
ETC…..
No lo entiendo, y si no lo entiendo no me entra……….
Para nz, sigo viendo todas las anotaciones del foro en ingles……..
Un saludo a todos.
Academia OpositasHola MariaJosé73:
Para entenderlo tenemos que empezar desde los bits que son simplemente los famosos “unos y ceros” es decir “abierto o cerrado”.
Vamos a necesitar 8 bits para que su combinación de ceros y unos nos determine un carácter o, para que nos entedamos una letra.
Cada letra en un archivo de texto va a suponer un byte.
Si juntamos 1024 bytes ya tendremos un megabyte.
Con 1024 megabytes tendremos un Gigabyte.
Con 1024 gigabytes tendremos un Terabyte, etc.
En tu tabla (la que os ofrecemos en el temario) vemos el valor posterior en relación con el anterior y puede que así lo veas peor. Espero que con esta forma de verlo podamos haberte resultado de ayuda.
Un saludo
