Relationship of Byte, Word, bit, byte

Word Word
Bytes Byte
Bit bits
The length of the word is the term

1 words = 2 bytes (1 word = 2 byte)
1 bytes = 8 bits (1 byte = 8bit)

A word with a length of 16
The word length of a byte is 8

BPS is the abbreviation for bits per second. The transmission rate of general data machine and network communication is in "bps" unit. such as 56Kbps, 100.0Mbps and so on.
BPS is the abbreviation for byte per second. Computers generally display the speed in bps, such as 1Mbps approximately equal to KBps.
The smallest unit in a bit computer memory, in binary computer systems, each bit can represent a 0 or 1 digital signal.
A byte of byte consists of 8 bits, which can represent a character (a~z), a number (0~9), or a symbol (,.?! %&+-*/), which is the basic unit of memory storage data, requires two bytes for each Chinese character. When the memory capacity is too large, the unit is not enough, so there is a thousand tuple unit KB appear, the following is a memory unit of the correlation between:

1 Byte = 8 Bits

1 KB = 1024x768 Bytes

1 MB = 1024x768

1 GB = 1024x768

USB2.0 Standard interface transfer rate. Many people have misunderstood "480mbps" as 480 megabits per second. In fact, this is wrong, in fact "480mbps" should be "480 megabits per second" or "480 megabits per second", it equals "60 megabytes per second", we see the gap.

This starts with bit and byte: The bit and byte are translated as "bits", which are data measurement units, bit= "bit" or "bit".
The byte= byte is 1byte=8bits, and the two conversions are 1:8 relationships.
Mbps=mega bits per second (megabits per second) is the rate unit, so the correct argument should be that the USB2.0 transmission speed is 480 megabits per second, or 480mbps.
Mb=mega bytes (megabits, megabytes) is the unit of measure, 1mb/s (MBytes/sec) =8mbps (megabits per second).

What we call the HDD capacity is 40GB, 80GB, 100GB, here the B refers to the byte is the "byte".
1 KB = 1024x768 bytes =2^10 bytes
1 MB = 1024x768 KB = 2^20 bytes
1 GB = 1024x768 = 2^30 bytes

For example, the so-called 56kb Modem converted to 56kbps divided by 8 is 7kbyte, so the real download of files from the Internet is the speed of the hard disk is 7kbyte per second.
That is, B, which is related to transmission speed, generally refers to bit.
A capacity-related B generally refers to a byte.

Last but not least: the transfer rate of the USB2.0 480mbps=60mb/s is only a theoretical value, it is also subject to the system environment (CPU, hard disk and memory, etc.), the actual read, write to the disk speed of about 11~16mb/s. But it's also nearly 10 times times faster than usb1.1 's 12mbps (1.5m/s).
