It's a small difference, but it adds up over a while. So in actuality, one KB is really 1024 bytes, not 1000.
(You may have heard of kilometers (Km) which is 1000 meters). Why is this so? It turns out that our early computer engineers, who dealt with the tiniest amounts of storage, noticed that 2^10 (1024) was very close to 10^3 (1000) so based on the prefix kilo, for 1000, they created the KB. How many bytes are in a kilobyte (KB)? One may think it's 1000 bytes, but its really 1024. Since there are 8 per line, that's over (4000 x 8) 32,000 1's and 0's just for a single gif image. So a small gif image, about 4 KB has about 4000 lines of 8 1's and 0's. The string of code: 10010101 is exactly one byte. A kilobyte is eight times larger than a kilobit.Ī simple 1 or 0, times eight of these 1's and 0's put together is a byte. This came to be called a byte.Ī bit is represented with a lowercase "b," whereas a byte is represented with an uppercase "b" (B).
#Gb to byte code#
Why eight? The earliest computers could only send 8 bits at a time, it was only natural to start writing code in sets of 8 bits. Eight of these 1's and zero's are called a byte. The smallest amount of transfer is one bit. (one thousand) 10^3 (Kilometer, 1,000 meters) Bits, Bytes, Mega, Giga, Tera (explained)
