Representation of a Kilo/Mega/Tera Byte

Question

I was getting a little confused with the representation of different units of bytes.

It is accepted throughout that 1 byte = 8 bits.

However, in a lot of so

Answer 1

When you talk about data information in computer science, you always have to calculate the result by a power of two. See what wikipedia says:

"In computing, a binary prefix is a specifier or mnemonic that is prepended to the units of digital information, the bit and the byte, to indicate multiplication by a power of 2. In practice the powers used are multiples of 10, so the prefixes denote powers of 1024 = 2^10."

Sometimes people use to round it as you have mentioned, but it is a bad use of it.
