Binary numbers – bits, bytes, and representing information

Computer ScienceData & BinaryAges 11–12

A clickable sequence of 0/1 bits: each bit corresponds to a power of 2, and the decimal number is the sum of the bits that are set. Number mode converts between binary and decimal with a table of successive division by 2; Character mode shows the ASCII code and bit pattern as you type a character; Image mode lets you click cells to draw a black-and-white image, where each row is a sequence of bits. Students see that all information in a computer is ultimately a sequence of bits.
