Memory Measurements

Different Physical quantities has different aspects of measurement.

Example:-

Length is measured in Centi-meter/Meter/Kilometer.

Computer also has its memory and storage sizes measurement units.

Computer only understands the binary language.

The information stored in the computer is in the form of 0`s and 1`s.

0`s and 1`s is called as bits. bit means binary digit.

A bit is the smallest unit of the data/information.
A bit can have only a single value either 0 or 1.

Units of Computer Memory Measurements:

Bit                            = '0' or '1'
4 bits                       = 1 nibble
8 bits                       = 1 Byte
1024 Bytes             = 1 KiloByte
1024 KiloBytes      = 1 MegaByte
1024 MegaBytes   = 1 GigaByte
1024 GigaBytes     = 1 TeraByte
1024 TeraBytes     = 1 PetaByte
1024 PetaBytes      = 1 ExaByte
1024 ExaBytes       = 1 ZettaByte
1024 ZettaBytes    = 1 YottaByte
1024 YottaBytes    = 1 Bronto Byte
1024 BrontoByte   = 1 Geop Byte

Geop Byte is the Highest Memory Measurement Unit.

Size in "bytes"

Kilobyte    (KB)     =  1,024  bytes
Megabyte  (MB)    =  1,048,576 bytes
Gigabyte    (GB)     =  1,073,741,824  bytes
Terrabyte  (TB)      =  1,099,511,627,776  bytes

Petabyte    (PB)      =  1,125,899,906,842,624 bytes

Abbreviations:-

bit                =  Binary digit
Byte             =  B
KiloByte      =  KB
MegaByte    =  MB
GigaByte     =  GB
TeraByte      =  TB
PetaByte      =  PB
ExaByte       =  EB
ZettaByte     =  ZB
YottaByte     =  YB

BrontoByte  = BB

The unit closest to 1000 is attained as follows:

1 byte x 2 = 2
x 2 = 4
x 2 = 8
x 2 = 16
x 2 = 32
x 2 = 64
x 2 = 128
x 2 = 256
x 2 = 512
x 2 = 1,024 bytes (1 kilobyte).
