  • Applications of ICT
    • Telephone systems
      • Voicemail
        • delete or store multiple messages
        • forward  the message to another voice mail inbox, including being able to add an extra message to explain why its's been forwarded
        • different message if engaged, not answered or on holiday
        • voice recognition
      • Menus
        • provides the caller a choice of services available
          • e.g. school  (using extension numbers)
      • ringback
        • Recipient is engaged and the caller has an option to request a 'ring back' when the recipient gets off the phone.
      • Videophone
        • allows phones to make videophone calls, can see & hear each other.
      • Caller display
        • can look at the display screen to see who's calling. Can decide whether or not to answer the call.
      • Conference call
        • holding a telephone conversation to invite another to join the conversation
    • Banking
      • ATM - Automated Teller Machines
        • Customers insert card, ATM then reads the sort code and account number from the magnetic strip. The customer then puts in pin, which will send a request to database to check if pin matches, if it does, the ATM will give the customer various options, e.g. withdraw money
      • Credit/debit card
        • Electronic Funds Transfer at the Point Of Sale (EFTPOS)
        • Debit card - money transferred directly from buyer's bank account to vendor's bank account. if not enough money, then payment is refused.
        • Credit card -  temport loan by credit card company to pay for goods/sevices. Amount charged is added to the list of other charges the buyer has made over the month
      • Cheques
        • Magnetic ink character recognition is produced iusing a special magnetic ink and include cheque number, sort code adn account number. Sort code identifies bank & branch, The account number identifies the account within that branch and when the cheque number is added to these ,the cheque is uniquely identifiable
    • Software based training methods
      • Computer based training (CBT) is using the computer to assist with training, e.g. for students, employees etc.
    • Production control
      • used in manufacturing industry to automate the production process. The production control systems are configured to change their role based on what is being produced. Robots usually used to carry out the actual production
    • GPS
      • GPS satellites used to identify thei location aqnd this is then shown on an interactive map, this tells them where to go at each junction. If a wrong turn is taken, the GPS system wil reroute you.
      • Points of interest, e.g. railway stations , airports and city centres
    • Navigation
      • achieved by using web-based software e.g. google maps. User enters starting point and destination e.g. street name. Via points are places that should be passed through as part of the route. Options set, e.g. avoiding motorways, toll roads etc
    • Weather forecasting
      • measuring and recording data, modelling a forecast and producing the forecast information
        • temperatures, wind speeds, wind directions, visibility, cloud cover & rain/snow fall will be shown for each area (postcode)
      • Mesuring & recording data
        • Currently happening: satellite images, temperatures, rainfall, humidity etc.
      • modelling a forecast
        • complex computer models are used to predict what the weather will do in the future. GTS ennables weather observations to be passed around the world using high-speed communication links. Super comps. used for vast amount of data that needs processing
    • Limitations of using ICT
      • battery life - e.g. laptop can only last upto 3 hours without mains power supply. meaning not good for camping hols.
    • Use of networks
      • discuss the use of networks, e.g. work and home including advantages & disadvantages.
    • Distributed Databases
      • Partitioned
        • different parts of the data stored at different sites. No single site stores all the data.
          • Horizontal - data is separated across sites based on records
          • Vertical - Data is separated across sites based on fields. e.g. customer name, address etc would be under 'customer'
      • Replicated databases
        • are copied in their entirety at each site within the network, e.g. bank accounts will be stored at every branch of that bank
      • central database with remote local indexes - only stored in one single location
    • Use of distributed databases
      • Compare the storage, queries, data availability  local control, database design and backups of each type of DD.
    • Security issues of distributed databases
      • Interception of data, physical access to data, consistency & integrity of data
    • Decision making
      • expert systems
        • computer program made up of knowledge and rules that can be used to diagnose a problem. Used in decision making and recommending particular courses of action e.g medical diagnosis, printer troubleshooting
          • Components - knowledge base, interference engine and user interface.
      • MIS - Management information system
        • designed to organise info within an organisation in such a way that it can be used to produce useful information to the management of the organisation.
      • reliability of data
    • Digital television networks
      • pay per view - pay to watch particular programme
      • Voting - allows viewers to participate in a TV prog.
      • Game show participation - answering questions along with contestents
      • choosing camera angles -allows viewers to pick a camera angle
      • recording and live pause
      • feedback comments to tv studio
      • consider impact on individuals, television companies and broadcasters
    • Characteristics of systems
      • Personnell
      • Finance
      • Stock control
    • Exchanging info accurately and in a timely manner
      • how is it  achieved: validation, verification, procedures
      • importance: safety, customer satisfaction, profits

Mr A Gibson

Number two of two mind maps which show a great amount of detail related to the Implications of ICT in a range of settings (other resource) and some real life examples of the applications of ICT (this resource). Both of these provide useful examples which could be used in exam questions.
