'bit: (bit) binary digit 0 or a number 1 denotes a
Byte: minimum units (bytes) stored in the computer

1 Byte = 8 bit

Myth: When broadband 100 megabytes of broadband, the download speed is not 100 megabytes, because:
Broadband say 100 trillion refers to: 100Mbps, which is 100 trillion bits
download speeds of 100 megabits refers: 100MB / S , i.e. download speeds of 100 megabytes per second
Thus, theoretically 100 MB broadband actual download speed: 100 Mbps / 8 = 12.5MB / s

Byte = 1024 KB. 1
. 1 MB = 1024 KB
. 1 GB = 1024 MB
size 1 TB = 1024 GB mobile hard disk is located
. 1 PB = 1024 the TB
. 1 EB size = 1024 PB server is
1 ZB = 1024 EB
