Today we're going to be talking about Data Size. The smallest size we can have is called a bit. That bit can only be a 1 or a 0, and that goes back go binary we've been talking about. After that, we've got a Nibble, which is 4 bits, which isn't common but it's adorable. The Byte, which is very common, is 8 bits. A lot of things are expressed in binary Bytes. After we get past the tiny bit and the small Byte, we get bigger really fast. The next step up is a Kilobyte, 1024 Bytes, or 1,048,576 bits. After that there's Megabyte, or 1024 Bytes to the power of two. Then it's Gigabyte, 1024 Bytes to the power of three; Terabyte, 1024 Bytes to the power of 4, and Petabyte, 1024 to the power of 5. These get much bigger really quickly! ❤️ Support for this channel comes from our friends at Scrimba – the coding platform that's reinvented interactive learning: https://scrimba.com/freecodecamp
