2 What Is A Computer? An electronic device that receives data, processes data, stores data, and produces a result (output). An electronic device that receives data, processes data, stores data, and produces a result (output). A collection of electronic circuits, which can be on or off (open or closed). A collection of electronic circuits, which can be on or off (open or closed). These two states of the circuit are represented by two digits, 0 and 1, c. These two states of the circuit are represented by two digits, 0 and 1, called a binary system.

3 What is Data? Data: Data: information entered into the computer to be processed, which consists of the following: information entered into the computer to be processed, which consists of the following: Text, numbers, sounds, and images Text, numbers, sounds, and images People: People: the users of the computers who enter the data and use the output. the users of the computers who enter the data and use the output.

4 Data Communications Computer technology enables computers to communicate Computer technology enables computers to communicate You can send text, numeric data, voice or video data from one machine to another.
