Document Summary

Digitizing data turns it into zeros and ones so computers read the info. Formulation is said to be distinct or separable (no shades of gray) Not possible to transform one value into another by tiny gradations. Memory is arranged inside a computer in a very long sequence of bits. # of bits determines # of symbols needed (95 symbols for english) Asc2 determines symbols, 8 bit sequence is a byte. Converting binary is half of the problem. You must also describe the information s properties and the characteristics of contents also needs to be encoded. Place value-each place represents the next higher power of 10, starting from right. In binary, it has higher powers of 2. Each pixel is a combination of red, green blue. White is the full intensity of each color. Use a byte to denote intensity of each color. Use a byte to denote intensity of light.
