9Information Technology Information Technology is the process of gathering and storing data to be used in various forms: It has:Streamlined access to vast sources of informationAllows us to produce more accurate forms of communicationExpanded resource choicesEnabled us to retrieve data in seconds
10Examples of Information Technology Data collected on paperData stored in computersData stored in booksData stored in equipment or machines
11Impacts of Information Technology POSITIVE IMPACTSNEGATIVE IMPACTSCOMPUTERS – use of a computer to gather data easily and storeINTERNET – using to store information for easy accessOBSCELENCE – machines need to be maintained and upgraded INTERNET – information is not always accurate or reliable
12Communication Technology Communication Technology is a process of giving or exchanging information.It has:Streamlined publishing techniques and allows us to produce more accurate drawingsExpanded entertainment choicesEnabled us to contact people thousands of miles away
13Examples of Communication Technology Cell PhonesComputer Aided DraftingVideo Cassette RecordingsInternetRadioTelevisionGraphic Arts
14Impacts of Communication Technology POSITIVE IMPACTSNEGATIVE IMPACTSCAD – using a computer to generate drawingsINTERNET – a means of communicating quickly and inexpensively over long distancesPAPER USAGE – people tend to create and print more documents INTERNET – people tend to misuse the internet for personal gain
15Bio-related and Agricultural Technology Biotechnology is the application of the principles of biology to create commercial products or processes.Agricultural Technology is the application of processes that make it possible for food to be available year-round and to conserve resources.Both deal with living thingsPlantsAnimalsPeople
16Examples of Bio-Related and Agricultural Technology Bio-related TechnologyPharmaceuticalsArtificial limbsGenetic engineeringHydroponicsImaging devicesCardiovascular devicesEthicsAgricultureFood, Fiber, and FuelPlant growthMachinesProduction of ag productsTransportation of ag productsStorage of ag products
17Impacts of Bio-Related and Agricultural Technology POSITIVE IMPACTSNEGATIVE IMPACTSHEALTH – improves quality of lifeHEALTH – Drugs may cause birth defectsENVIRONMENTAL – can produce more food per acre than beforeENVIRONMENTAL – Chemicals have found their way into ground water, polluting good drinking water
18Medical TechnologyMedical Technology is the study of medicine through the use of and advances of technology, such as medical instruments and apparatus, imaging systems in medicine, and mammography.Related terms: Bio-medical EngineeringMedical Innovations.
19Examples of Medical Technology Medical instruments and apparatusVaccinePharmaceuticalsArtificial limbsImagining equipmentErgonomics – the study of designing equipment to fit the human body, its movement & thinking patterns
20Impacts of Medical Technology POSITIVE IMPACTSNEGATIVE IMPACTSHEALTH – improves quality of lifeHEALTH – use of technology may hinder life spanDISEASE – research on controlling diseases and their spread is shortenedDISEASE – not all cultures embrace use of vaccines and thus disease spreads
21Environmental Technology Environmental Technology is study of the processes to control waste, soil erosion, reducing sediment in waterways, conserving water, and improving water quality, artificial ecosystems, and the effects of technology on the development of flora and fauna.
22Examples of Environmental Technology ConservationSynthetic energyWaste management
23Impacts of Environmental Technology POSITIVE IMPACTSNEGATIVE IMPACTSEARTH – improves quality of lifeEARTH – use of technology may hinder life span of the planetDISEASE – reduces chance of disease from bad air and chemicalsDISEASE – economical forces the need to make choices that are not easily made
24Production Technology Production Technology is the manufacturing of physical goods on an assembly line and the construction of structures on a job site.
25ManufacturingManufacturing is the process of changing materials into usable productsNatural (found in nature) orSynthetic (human-made)Most takes place in factories on assembly linesResults in items that are either consumer products (used up) or industrial products (used to make other products)
26Examples of Manufacturing Technology ClothingEntertainment devicesAutomobilesChemical productsLumberSteelFood
27Construction Technology Construction Technology is the study of the processes toBuild a structure – made by joining parts to meet a certain need.Involves building a foundation, erecting the super structure, and finishing work.Support the load – external force on an object.Control the quality of construction using control systems.
28Examples of Construction Technology Human-made structure:HousesHigh-rise buildingsBridgesRoadsDamsSchools
29Impacts of Production Technology POSITIVE IMPACTSNEGATIVE IMPACTSMANUFACTURING – new products help to make our life easier and increase leisure time.MANUFACTURING – many industries use materials that can harm the environment.CONSTRUCTION – provides shelter, improves roads, creates employment opportunities.CONSTRUCTION – noise and debris, traffic problems, accidents & injuries
30Transportation Technology Transportation Technology is the process by which people, animals, products, and materials are moved from one place to the next.FlightLand TransportationWater TransportationGoods Transportation
31Examples of Transportation Technology AirAirplaneRocketSpace ShuttleHelicopterWaterCommercial shipsCruise ShipsUtility vesselsLandTrainSubwayAutomobileBicycleGoodsConveyor BeltsRobotsTrucks
32Impacts of Transportation Technology POSITIVE IMPACTSNEGATIVE IMPACTSCommuting is easier;Traveling long distances fasterPollutionAccidentsUse of energy
33Energy and Power Technology Energy is the ability to do work.Power is the rate at which energy is transformed from one form to another or as the rate at which work can be done.Technological products and systems need energy to function.The availability of energy often determines the development of technology.
34Examples of Energy and Power Technology Chemical EnergyGasolineMechanical EnergyMotionThermal EnergySteamPower Measurement Examples:HorsepowerKilowattElectrical EnergyElectricityRadiant EnergyLightPower System Examples:TurbinesPortable generators
35Impacts of Energy and Power Technology POSITIVE IMPACTSNEGATIVE IMPACTSWithout energy and power, most technologies would not exist or work.The overuse of natural resources is a concern of many people.
