WebIn a byte, i.e. eight bits, we can represent numbers up to 2 8 -1 = 256 - 1 = 255. Because of the importance of bytes, we will concentrate on being able to write numbers as 8-bit sequences, and being able to interpret an 8-bit sequence as a number. The smallest number we can represent in 8-bits is 0, which is the byte 00000000. WebView Notes - PHYS317-Pset-3_0_09_04_2024_18_39.jpg from CSC 269 at Harvard University. 1.
