Generally, a computer is any electronic data-processing device that performs tasks, such as mathematical calculations or electronic communication, under the control of a set of instructions called a program. Programs usually reside within the computer's main memory and are retrieved and processed by the computer's electronics, and the program results are stored or routed to output devices, such as video display monitors or printers.

Science is the objective pursuit of reliable knowledge.

Business, Economics, Education, Family, Geography, Language, Philosophy.

Science refers to a body of knowledge, or a method of study devoted to developing this body of knowledge, concerning the nature of the universe gained through methodological observation and experimentation (scientific method). Exactly what constitutes science and scientific methods are subjects studied by the philosophy of science.
