Document Summary
1. information (conceptual) managed using binary digits (1and 0: hardware (physical) includes gates and circuits and devices that control the ow of electricity, programming software- the instructions used to accomplish computations and manage data. Goal: to solve problems: operating system manage the way hardware devices, programs, and data interact, applications focuses on using the computer to solve speci c real-world problems, communications networks-used to share information and resources. Abstraction a way to think about something which removes or hides the complex details. It leaves only the information necessary to accomplish a goal. Used punch cards as a way to input numbers and mechanical steps. His design was too complex for the technology available to him so he never implemented it. She extended the ideas of the analytical engine. She also came up with the concept of the loop- a series of instructions that repeat. Invented an abstract mathematical model called the turing machine.
