What is the difference between K and KB

k and kb are two completely different concepts: K means thousands, which is a numerical value; and KB is a unit, where B is a byte, KB Represents kilobytes.

G, M, and K all represent numerical values, which refer to 2^10, 2^20, and 2^30 respectively; while B is 1 byte, and B, KB, MB, and GB are all units.

KB stands for kilobytes, which is a unit of information measurement that is commonly used today to indicate the storage capacity of storage media with general capacity such as memory.

Note: When talking about file size, B may sometimes be omitted, so that K and KB are the same, But in fact this is not rigorous, you need to pay attention .

Conversion between B, KB, MB, GB:

● 1B=8bit

● 1KB = 1024B = 1024 * 8bit (1KB : 1024 bytes, that is, 2^10 bytes, not 1 byte)

 ● 1MB = 1024KB (1MB: 2^20 bytes)

 ● 1GB = 1024MB

bit (binary digit): A bit is the smallest unit of computer data. The value of the bit will only be 0 or 1. Although computers also provide bit judgment and operations, computer instructions are generally in bytes. In most computer systems, eight bits are a byte. The value of a bit is usually measured by whether the storage capacitor is charged.
