AP Computer Science Principles Unit 3

Four essential functions of computers

Taking input, storing information, processing it, and outputting results.

Evolution of Computer Technology

The development of computers from early mechanical devices to modern electrical machines.

Input Mechanisms for Computers

Methods through which computers receive information and instructions for tasks.

Processing

The manipulation of information by the computer's processor based on algorithms.

Output of Information

The results produced by a computer, which can take the form of displays, games, or signals.

Future of Computing

The uncertain advancement and development of computer technology.

Function of Input

The actions and information that instruct the computer on what tasks to perform.

Role of the Processor

To manipulate information stored in memory based on algorithms.

Example of output forms
