A computer is a machine that uses electronics to input, process, and then output data. Input of data means to read information from a keyboard, a storage device like a hard drive, or a sensor.
The computer processes or changes the data by following the instructions in software programs. A program is a list the steps for doing arithmetic, comparing data, and re-arranging data.
The data is then saved in a storage device, shown on a display, or sent to another computer.
Computers can be connected together to form a network such as the internet, allowing the computers to communicate with each other.
