The storage unit of the computer

bit: bit. The smallest unit of storage in a computer, the binary computer has 0 or 12 types of values, and the computer uses a different 0-1 combination to represent different information.

BYTE: Byte. 1byte = 8bit, file size is usually in bytes, an English character is 1byte, and a Chinese character takes up 2byte.

1KB = 1024byte

1MB = 1024kb

1GB = 1024MB

Bps:bit per second, that is, bit rate, bit/s. BPS is a common unit of data transmission, such as 100Kbps, 100Mbps.

Bps:byte per second, that is, Bytes/s, 1Bps = 8bps. BPS is a common unit of computer transmission.

The size of the hard drive: for example, 16G, when 16G represents 16gb,b is byte, that is, byte.

USB Transfer speed: For example, 480mbps,mbps represents the megabits, the bit is bit,480mbps = (480/8=60) MB. MB is a byte unit, 1mb/s (megabytes per second) = 8mbps (megabits per second).
