Detailed explanation-1: -In the International System of Units (SI) the prefix kilo means 1000 (103); therefore, one kilobyte is 1000 bytes. The unit symbol is kB.
Detailed explanation-2: -Traditionally, 1 kilobyte is used to express 1024 bytes (210 B). The concept of metric kilos is used here because 1024 is close to 1000 for convenience. Today, this notation format is used in many places. Example: Microsoft Windows.
Detailed explanation-3: -1 kilobyte (KB) is equal to 1024 bytes. This is based on the definition of the kilobyte, which is equal to 1024 bytes. The prefix “kilo-” means 1, 000, but in the case of the kilobyte, it is used to denote 1024 (2^10) bytes. This is because the kilobyte is based on the binary system, which uses base-2 units.
Detailed explanation-4: -1024 bytes are there in a kilobyte. 1KB= 1024 byte. 1 Byte = 8 bit.
