Engineering Science 1036A/B Lecture 3: Introduction to Computer and Java
Computer and programs: processors: circuits created to process executed code, memory: stored as 0s and 1s. Instructions represented as 0s and 1s are known as machine instructions. Executable program: a sequence of machine instructions together from an executable program. Assembly: programmers created programs called assemblers to, automatically translate human readable instructions such as "mul 97, #9, 98" into machine instructions, known as assembly language instructions. High-level languages: programming using formulas or algorithms. Support high-level languages, programmers created compilers, which are programs that automatically translate high-level language programs into executable programs. Language history: c in 1978, c++ in 1985.
