Chapter 1 - Introduction to Information Technology

Define computer.

• A machine that can be programmed to accept data (input), process it into useful information (output), and store it away (in secondary storage device) for safekeeping or later reuse

• Any technology that helps to produce, manipulate, store, communicate, and/or disseminate information.

• The interrelationship of user (people) to communicate with programs (software) and physical components (hardware)

• Accept data or commands in a form that the computer can use; they send the data to or commands to the processing unit.
