a value that does not change throughout the program
the study of a complex process in order to improve its efficiency
updating a program to correct faults or improve features
an electrical signal with voltage changes that are abrupt or in discrete steps
a description, independent of any programming language, of a process that achieves some task. it is a step-by-step procedure for solving a problem
