So the numbers that are turned ON are 64, 32, 2, and 1 and added up together. The decimal value 99 is same as the binary value 0110 0011. You’ll need to use some math for this question. Using the handy chart that we learned in the lesson, convert this number to its decimal value. The binary value of the ASCII letter “c” is 0110 0011. There are 256 values in a byte, from the decimal number 0 to 255. What is the highest decimal value we can represent with a byte? This allowed us to represent a lot more character types, like emoji. UTF-8 replaced the ASCII character-encoding standard because it can store a character in more than a single byte. ASCII can store a character in more than one byte.UTF-8 can store a character in more than one byte.Why did UTF-8 replace the ASCII character-encoding standard? So 2^8 allows us 256 values from 0 to 255. How many possible values can we have with 8 bits?īits use the binary system, which is also known as the base-2 numeral system. Which of these is a valid byte? Check all that apply.Ī byte is composed of eight bits of zeros and ones. So let’s get started!
