Lecture 3 COMM 202: Introduction to Communication Technology Varying bits and variations can be illustrated with picture resolution. 8 bit 16 bit Lecture 3 COMM 202: Introduction to Communication Technology Bits and resolutions Natural light signal is represented by color variations. The more variations available for computing, Lecture 3 COMM 202: Introduction to Communication Technology The idea of bits show how digital technology is different from older media technology. Lecture 3 COMM 202: Introduction to Communication Technology Digital is much less proportional, and more discrete: it exists or not exists. To represent reality well in digital form, Lecture 3 COMM 202: Introduction to Communication Technology More examples: Lecture 3 COMM 202: Introduction to Communication Technology Advantages of digital technologies Lecture 3 COMM 202: Introduction to Communication Technology Limitation of digital technologies...
