Units of Computer Memory Measurements:

Units of Computer Memory Measurements:

1 Bit = Binary Digit
8 Bits = 1 Byte
1024 Bytes = 1 KB (Kilo Byte)     10³
1024 KB = 1 MB (Mega Byte)        10⁶

1024 MB = 1 GB (Giga Byte)         10⁹
1024 GB = 1 TB (Terra Byte)           10¹²
1024 TB = 1 PB (Peta Byte)               10¹⁵
1024 PB = 1 EB (Exa Byte)         10¹⁸
1024 EB = 1 ZB (Zetta Byte)        

1024 ZB = 1 YB (Yotta Byte)
1024 YB = 1 Bronto Byte
1024 Brontobyte = 1 Geop Byte

Geop Byte is The Highest Memory Measurement Unit!!!
