One Kilobyte is equal to how many bytes?

Explanation:
In computing, memory sizes are based on powers of two. A kilobyte means 2 to the 10th power bytes, which is 1024 bytes. That 2^10 root fits neatly into how bytes and addressing work, giving a convenient chunk of data. The other numbers are 2^8, 2^9, and 2^11, corresponding to 256, 512, and 2048 bytes, but they don’t match the standard kilobyte size. So, 1 kilobyte equals 1024 bytes.
