Computers and Programs A computer is a universal information-processing machine Computer science is the study of what can be computed: design, analysis, and experimentation Computer system comprised of: 1) CPU, the brain 2) CPU acts on data and programs in main memory (RAM), 3) More permanent memory in secondary memory devices All languages share property… Continue reading Python Programming: An Introduction to Computer Science
