(smaller to greater )

→ 8 bits = 1 byte

→ 1024 bytes = 1 Kilo byte ( KB )

→ 1024 KB = 1 Mega byte ( MB )

→ 1024 MB = 1 Gigabyte ( GB )

→ 1024 GB = 1 Tera byte ( TB )

→ 1024 TB = 1 Peta byte ( PB )

→ 1024 PB= 1 Exabyte ( EB )

→· 1024 EB = 1 Zettabyte ( ZB )

→· 1024 ZB = 1 Yottabyte ( YB )

→· 1024 YB = 1 Brontobyte ( BB )

→· 1024 BB = 1 Geopbyte
