The difference between K and KB: 1. The concepts of k and kb are different; 2. K means thousands, which is a numerical value, and KB is the unit, where B is bytes and KB means kilobytes.
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.
