Input and Output

1. What is input?

   • An input is data that is entered into or received by a computer. This could include a user pressing a key on a keyboard, clicking a mouse to select something on screen or tapping a touch pad. Some inputs indicate to the computer what we want it to do, while others provide data for the computer to process.

2. What is output?

   • Any information processed by and sent out from a computer or other electronic device is considered output. An example of output is anything viewed on your computer monitor screen, such as the words you type on your keyboard.

3. What is a computer system?

   • A computer system consists of hardware components that have been carefully chosen so that they work well together and software components or programs that run in the computer. The main software component is itself an operating system that manages and provides services to other programs that can be run in the computer.
