Tech Bowl 4

Input

Something put into a system, such as resources, in order to achieve a result.

Output

The results of the operation of any system.

Process

A series of actions or steps taken to do work with an input

Feedback

Information about the output of a system that can be used to make adjustments.

Goal

The purpose of operating a system

Open Loop System

A system that can not monitor it's own output and has to rely on human feedback to control it.

Closed Loop System

A system that monitors it's operation, compares it to it's programming, and adjusts itself to maintain good operation

Technology

The use of tools, resources, and knowledge to create systems, tools, and techniques to meet a want or need.

Technique

A way of doing something

System

A group of parts working together to achieve a goal

Tool

A device we do work with

Resource

A material or information we do work to

Want

Something we can live and be safe without

Need

Something we would die or be harmed without

Energy and Power Technology

Technology for Generating, Controlling, Storing, and Transmitting Energy

Transportation Technology

Technology for Moving people or cargo from one place to another

Medical Technology

Technology for Preventing, Treating, and Diagnosing Illnesses and Injuries

Agriculture and Bio Technology

Technology for Using and Caring for Organisms from Fungus and Bacteria to Plants and Animals

Construction Technology

Technology for Building Structures

Communication Technology

Technology for Creating, Sending, and Receiving information

Manufacturing Technology

Technology for Planning and Producing items

Technological Impact

The result of using technology

Stone Age

A period of time during which early humans made lasting tools and weapons mainly from stone; the earliest known period of human culture

Bronze Age

A period of time after humans learned to smelt metal. Agriculture and large cities were starting to play a major role in human life

Iron Age

A period of time dominated by the Romans. Steel, roads, and professional engineering were developed.

Middle Age

"Medieval Times" is another name for this period of time. Castles, Sailing ships, and Printing are technologies know from this period

Renaissance

An age of technology where math, science, and art developed at a fast pace. Most basic scientific tools like microscopes or thermometers were develop during this time.

Industrial Revolution

A period of rapid growth in the use of machines in manufacturing and production that began in the mid-1700s

Industrial Age

The period of time after the Industrial Revolution. Many people moved to cities. Machines powered the tools used in the fields and factories.

Information Age

The current technological age brought to us by the Transistor. Information and Electronics that use information dominate our lives.

diode

A device that permits current to flow through it in only one direction.

transistor

A small electronic device used in a circuit to amplify a current or switch a current on/off.

servo motor

a motor that can be positioned within a given angle range using Pulse Width Modulation (PWM)

signal wire

the wire used to send voltage to a component to make it work or to receive information from a sensor for the Arduino to interprete

dc motor

small electric device that converts direct current electricity into mechanical motion

transistor collector

on a transistor, it is the positive lead where you supply voltage to run a component

transistor base

on a transistor, it is the lead where you supply the single to control the transistor

transistor emitter

on a transistor, it is the negative lead where you connect the component

Arduino library

a collection of functions that are specific to a connect component

#include

the code use to add a library to a program

piezo element

a component that vibrates when electricity is passed through it.

pullup resistor

a resistor used to connect a component to a positive voltage so it can used that voltage as a baseline

pushbutton

a button that you push

floating voltage

a voltage that is created in a circuit that is unregulated and can confuse programming or damage components

Light Emitting Diode

A diode that will produce light when current flows through it.

Resistor

An electrical device that resists the flow of electrical current

Jumper Wire

used to establish connections between the central micro controller and other devices such as buttons and sensors.

Breadboard

A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work.

Ground

common return path for electric current, another name for the negative connection point
