Unit 8  Dealing with the Analog WorldComputers by their very nature are digital devices. Digital data are discrete. At some level all numbers a computer knows are broken down into a series of nes and zeros. Luckily we don't have to do that ourselves to program them. A quick example of digital vs. analog would be the number of students in a classroom at school. You can have 28 or 29, but you can't have 28.7 students. The number of students represents discrete data so can be easily turned into digital data. The total mass of students in the room is continuous. There might be 1909 kg of students in the room. If one ate a Big Mac then there would be 1909.27 kg of students in the room. We can have vary fine gradations in mass. The total mass is like analog data. We live in an analog world. If we convert the analog mass to digital number of students we could not represent the added student flesh due to the Big Mac.
