Question

Difference between computer keyboard and calculator keyboard

Answer 1

Calculators are single-purpose devices that perform mathematical operations input by the user. Simple calculators just do four-function math, while more advanced calculators handle trigonometric functions, take square roots, and graph equations for solving algebra problems. While some calculators can store series of instructions, they don't run programs that interact with the user or take user input. Computers are calculators that have vastly expanded capabilities, and are often called "general purpose computing devices." Computers can do everything a calculator can do. Every graphical user interface operating system has a virtual calculator, as do most cell phones.
