  1. Benefits and Limitations ofICT Systems

  2. Benefits of ICT Systems • 1. Increased speed of processing (e.g. MICR in a bank) • 2. Massive Storage capacity (compare filing cabinets to databases) • 3. Environmental gains (Will there ever be a "paperless office"?) • 4. Ability to search and combine data in many different ways (e.g. speed of searching a database vs. searching a filing cabinet) • 5. Instant Response - Computer processing power is measured by how many millions of instructions per second (MIPS) they execute.

  3. Benefits of ICT Systems Cont…. • 6. Accurate and consistent results vs your grand mother doing algebra. • 7. Communication (e.g. Email,MSN Messenger, Facebook) • 8. Improved Company Image • 9. Work tirelessly 24 hours a day, seven days a week without breaks • 10. Consistent results

  4. LIMITATIONS OF ICT • 1. Job losses • 2. Faults in software (bugs or badly designed programs) can cause chaos. • 3. We are completely reliant on electricity • 4. Information overload (e.g. people can be flooded with Email) • 5. Computer crime (hacking, viruses) • 6. Lack of hardware and software standards

  5. HUMAN Advantages • Thinking • Judgement • Creativity • Motivation • Flexibility • Mobility • Storage • Working with Knowledge

  6. COMPUTER Advantages • Speed • Accuracy • Dependability • Little Training • Required Lower costs (in most cases) • Information Processing

  7. COMPUTER limitations • Not creative, but they can solve problems for humans. • Can’t reason. Although a computer shares similarities with the human brain and nervous system they lack many of the mental capabilities possessed by a 5 year old child. • Can’t discriminate or assimilate widely different kinds of data and they have no capacity for ethical evaluations. • Do not make errors. Programs do. • Are literal i.e. might accept 1 but not one, copy but not coppy • Operate logically but are incapable of acting rationally

  8. Exam Questions • Using the knowledge from this presentation you should be able to develop answers in relation to ICT and society • Use this ppt as a reference for the rest of the tasks in this section
